Odonates tend to glide, fly, hover, and move frequently. During transect surveys, it is possible to count one individual more than once if it flies back and forth. Is there any method (statistical or some protocol to be followed by the researcher) to avoid this error?
Relevant answer
Answer
To avoid repeated counting of individuals during an Odonate Transect Survey you can follow these strategies:Establish Clear Survey Routes: Define specific routes or areas for your survey. Clearly mark the boundaries and ensure surveyors know where to start and finish, reducing the chances of double-counting.Use Marking Techniques: If possible, mark the individuals you have counted without harming them. For example, you can use non-toxic, temporary markers like colored dots on wings. This way, you can identify previously counted individuals and avoid counting them again.Time Gaps Between Surveys: If conducting multiple surveys in the same area, introduce time gaps between surveys. Odonates are highly mobile, so waiting for a while can allow them to disperse, reducing the likelihood of recounting the same individuals.Record Environmental Conditions: Note down environmental factors such as temperature, humidity, and wind speed. These conditions can affect odonate behavior. If conditions change significantly between surveys, it's less likely that the same individuals will be present.Train Surveyors: Properly train surveyors to recognize odonate species and avoid counting the same individuals multiple times. Training can enhance the accuracy of the survey results.Use Standardized Survey Methods: Adhere to standardized survey protocols and guidelines. Following established methods ensures consistency and helps in minimizing errors related to repeated counting.Employ Technology: Consider using technology like photography or video recording to capture the odonates during the survey. Later, you can review the recordings to confirm identifications and avoid double-counting.

What is the Schistosomal Life cycle and infections with the host of Public Health Entomology?
Relevant answer
Answer
The Schistosomal life cycle involves a complex interplay between humans and freshwater snails, and public health. While these snails are not insects, they play a vital role in the transmission of schistosomiasis, and their study is important in understanding and controlling the disease. In this context, public health entomologists may extend their expertise to include snail biology and ecology due to their relevance in the life cycle of the parasites causing schistosomiasis.

It's known that phytates are a P storage in plants, in particular seeds. Plants produce enzymes to release P upon need. Also ruminants can digest phytates thanks to their gut microbiome. However, for many animals phytic acid is an antinutrient because it binds nutrients in cationic form (Ca2+, Mg2+ etc.). Insect have proven able to digest a wide variety of substrates thanks to their gut microbiome. I found mentions of phytates in insect-based products, but it wasn't addressed whether insects can digest them. Do you know if any experiment proved they can digest phytates?

Answer
The cubital index is a measure of the relative length of the cubital vein, which is a vein located in the forewing of a honeybee. The cubital index is calculated by dividing the length of the cubital vein by the length of the wing and expressing the result as a percentage.
The cubital index is used as a morphological character in the identification and classification of honeybee subspecies and populations. It has been found that the cubital index can vary significantly among different honeybee subspecies and populations, with some subspecies having a relatively long cubital vein and others having a relatively short one.
There is some evidence to suggest that the cubital index may be related to the foraging behavior of honeybees. Some studies have found that honeybees with a higher cubital index may be more efficient at foraging and more successful at finding food resources, while those with a lower cubital index may be less efficient at foraging.
In addition to its use in the identification and classification of honeybees, the cubital index may also have practical applications in the management of honeybee colonies. For example, some beekeepers may use the cubital index as a tool for selecting bees with desirable foraging traits for breeding purposes.

Hi frds,
if organic farming were to be implemented 100%, what is its capacity in feeding the global population?
Cherish your insights.
Relevant answer
Answer
Dear Thomas Schuermann, the question is interesting and full of meaning. When we look at the history of the agricultural revolution, unfortunately, it was both an opportunity and a threat. The decline in human resources in the agricultural sector, the increase in production per unit area, was given opportunity, but caused serious threats, erosion and environmental pollution (types of diseases, etc.). Therefore, the people of the world (even leading countries) will not have a good future in the field of health and food security. So, organic farming can help reduce the problems facing the world. In this regard, a research paper has been attached that can help us achieve our goals for the first time in a managed target area.

Hi frds,
If organic insect-aware farming were to be implemented completely, assume bad harvests such as the potato famine would be around the corner at some stage.
What is the tradeoff of organic farming vs short-term stable pesticide farming with potential disruptive biodiversity loss in the insect population in the long term?
Cherish your research and/or qualitative opinion.
Relevant answer
Answer
The idea that organic farming represents a low yield and solution is erred.
The Rodale Institute Farming Systems Trial show that comparative yield using strictly organic biological based inputs is completely competitve to agrichemical reliance.
As furth example I would take the case of potato farming which has enormous ability to provide nutrition directly to consumers. Commercial potato farmers have become major users of compost in order to increase both the yield and quality of potatoes.
The hungry potato crop responds very positively to compost and rotation which are core organic practices allowing both high yields and reduced use of pesticides.
The idea that pesticides and fertilizers guarantee high yield and stable production is flawed.
After a 3-year transition to organic agriculture the Rodale Institute has shown there is no significant reduction in yield and in years of drought the organic systems improve yields over conventional agriculture.
The reliance of solely the use of agrichemical inputs increases farmer costs but biological inputs can avoid their side effects and lead to high more stable production of maize, soybean and wheat which are major field crops in North America.
The use of organic agriculture techniques reduces the carbon foot footprint of the production systems and the ability to increase soil carbon and nitrogen not only counteracts need for synthetic inputs but also contribute to counterbalancing the enrichment of atmospheric greenhouse gases,

I'm very curious about which courses did or did not stop insect collection for education purposes. And if so, what alternative methods are used now to teach taxonomy, biodiversity monitoring or insect morphology?
Because of the increasing moral concern about collecting and killing insects for the sole purpose of educating insect identification or monitoring techniques, exploration of alternatives are needed. This can be challenging.
If still traditional methods are used (i.e. collecting, killing, preserving insects) for teaching, is there a discussion about ethical arguments?

It depends on students' major, but ... How about concentrating on agricultural pests, those which will be controlled by pesticides anyway? They must cover enough diversity of insects for education purpose.

I have insects stored for morphomolecular species identification in ethanol (EtOH). These weevils (Larinus spp.) were stored in 100% EtOH at the recommendation of more experienced entomologists. Now that I am trying to pin these weevils, they are quite brittle and difficult to pin without cracking an elytrum. It was suggested to me that I could dilute the EtOH in the storage vial to ~80% to 95% to rehydrate the weevils enough for pinning, but I am concerned this may result in DNA degradation.

Hi everybody,
we are using circular pitfall traps (regular yogurt cups) since many years, and unfortunately, sometimes we encounter mice and lizards as by-catch in our samples.
These animals fall in the pitfall traps, are not able to climb out of it and drown...
Researches (e.g. see link attached) and personal reflections resulted in the following possible easy-to-install preventive measures:
1) covering the pitfall traps with a thin, wide-meshed iron grid, so it is too thin to "grab and climb" for invertebrate, but slippery enough for insects and spiders
2) using funnels with a slippery surface, so small vertebrata can't enter, while insects can fall into it
I personally like more solution 1, but I wanted to ask you to share your experience :-)
We aim mostly on spiders, centipedes, millipedes, beetles and other surface insects.

I once attended a virtual event from one of the entomology societies in Europe. They say they are doing research by rearing locusts in the laboratory and then releasing them into nature for conservation purposes.
Why do you think they did that? Can you explain to me or share information regarding this?
What if one day the locusts that are released into nature actually migrate and cause harm to local agriculture and or even attack agricultural crops in other countries?
Please give your best opinion.
Thankyou. Best Regards!
Relevant answer
Answer
Locusts in natural ecosystems are an integral component. She plays an important role and ultimately - useful. In agroecosystems, locusts are harmful. The term harmful and useful insect was coined by man to describe the role of each insect in relation to man. But there are no harmful species in nature. The problem of locust harm lies within ourselves. An agroecosystem is a monoculture. When plants are grown in a small area field that are a food source, this causes a surge in the number of the locustes. Not all locusts harm the fields, only 3 species potentially cause crop damage.

In early 2022 I'll be completing a length field campaign, collecting Lepidoptera, Odonata and Hymenoptera in a very humid flooded forest in central Africa. Due to the nature of this work we will not be able to use conventional drying boxes, and will not have access to any electricity (we are not taking a generator for logistical reasons). What is the best approach to drying and preserving these specimens (which will number in the thousands) in the field?
Our proposed solution currently is a makeshift drying box with an air intake we will position over a fire, before storing in tupperware with silica crystal. However, this method is difficult to maintain and ensure equal and not excessive drying. One proposed solution is direct immersion in silica crystal, but this is not possible with delicate specimens which will later be analysed for pollen loads (contamination an issue). Alternatively, one could dry specimens in direct sunlight, perhaps under black tarpaulin, but our habitat type is not convenient for this. Drying is necessary (as opposed to e.g. alcohol immersion) due to other aspects of the research.

Hi,
I notice that oppose to many other Heteroptera, Sciocoris move their antenna fidgetly. I assume it related to an antennal sensory organ. Does anyone know why does it do that and if I can expect to fine any unique structure on its antenna compare to antenna of other Heteroptera which doesn't act like that?
See example to antennal movement in attached movie.
Relevant answer
Answer
Dear Assaf Nir
This effect is also observed in other insects.
I can assume that this is related:
1. When the insect is frightened: by chemical irritants or in case of danger to life.
2. It is possible that an individual examines a new stop using antennas.

Dear Entomologists, I need to pick the swarm brain.
I'm planning to mark moths with fluorescent dust for better observation and recapturing at night. Can anybody provide experience with DNA extraction from insect marked with this kind of dust? Or point me towards suitable publications? I can't seem to find any. There is lots of mosquito marking, but without subsequent DNA extraction.
Thank you, swarm :-)

Answer
@Patrick Gorring
Thanks for your answer and making me realize that my question is not clear. Should have seen this from David's answer already. My concern is the contamination of the extracted DNA with the pigments, not with DNA from unclean dust. In the past, we had trouble with eye pigments inhibiting PCR, for instance.

I am planning on starting grad school in about a year and a half but you can never start researching project advisors too soon!
I am interested in investigating the use of fungal parasites of insects such as Cordyceps in integrated pest management. Unfortunately, this seems to be an unpopular field of study, as so far in my searches I have only seen professors who study plant-insect relationships in IPM, but not fungal-insect relationships in IPM. Ideally, I am hoping to stay on the west coast of the US. My undergraduate background is in ecology and evolutionary biology, but I am currently broadening my skills in molecular lab techniques.
Faculty pages on university websites cannot always represent the scope of a professor's research interests. That said, can anyone recommend a recommend a colleague of theirs who might be looking for graduate students in a year and a half, and with a background in mycology, entomology, and IPM?

Biological experiments are nowadays being added as preprint in different archives such as biorixv.. Can an author add taxonomic descriptions as well before published as a journal article?
Relevant answer
Answer
Publishing descriptions of new taxa as preprints is definitely a bad idea.
(i) the name would very probably not be made available through use in a preprint
(ii) others could start using the name before the description has been officially published, causing confusion with regard to priority and date of publication
(iii) as Thierry Bouyer pointed out, someone else could come in and quickly describe the same taxon using their own name. Taxonomic vandalism is a thing...
Under the rules of the Code, nothing could modify that (although herpetology has challenged those rules in recent years).

I would like to observe/ record insects behavior under webcam setting at night. So we are looking for some suitable infrared(Red light) lamps or IR LED to do this. Can anybody recommend us some proper products?
Relevant answer
Answer
Hi,
In the paper attached, we used DC-Infra, 620.5–645 nm LED. It's not infrared per se, but it's red light, close to the IR spectrum. It was enough to keep our carabid beetles undisturbed by the light source.
In another project on aphids, I have used Sima 36-LED (Hauppauge, NY, USA) and Vision Technologies IR-130 (Houston, TX, USA) infrared lights, coupled with a full spectrum Sony A6000 camera. It worked nicely and we recorded nice footage of insect behavior at night.
Hope this helps,

Hi, i have been working with Canada balsam as mount medium for Thysanoptera slices, but it´s too old and thick, i´ve tried using xylene to dissolve it, but it´s not working. So my question it´s maybe someone has tried using other mount medium for Thysanoptera species?
Relevant answer
A mixture of acrylic resins in xylene may be suggested. Drying time 20 - 30 minutes. Does not form bubbles. Ideal optical properties, the refractive index is 1.5. Stable when exposed to moisture, temperature, UV rays.
These are such mounting media as: Elyashev's environment, Kolbe's environment, Hyrax, Pleurax, Styrax, Caedax, Naphrax, ZRAX, Styraplus, Dammaplus
For preparations with Euparal, Malinol, water or oil immersion is not terrible, there is no crystallization.

Earth have diverse group of insects, if a species of insect got extinct, how we can assess and identify them? What are the criteria’s to follow?
Relevant answer
Answer
Dear Kariyanna,
I believe that several other replies here have added useful information for attempting to define this. Though I had some entomology courses and instruct a bit of this in my zoology teachings, I work largely with mammals. Extinction can be difficult, if not impossible, to verify for many species, so a consensus, such as the IUCN description is a useful working application.
In graduate school, a fellow researcher worked on a possible population census of wolverines in the state of Oregon. Though it was assumed that wolverines exist in Oregon, none were definitively sighted for several years. The research was based upon trace evidence - burrows, hair, tracks, and alleged sightings or predation of this species.
I myself assisted a colleague on trace evidence and reports of the thylacine (Thylacinus cynocephalus) in Tasmania. Largely considered to be extinct, but with continued reports, some from reputable sources. Is it extinct? Most mammalogists would say yes, but I am still uncertain with some of the reports and a large amount of suitable habitat that is difficult to access. On the other hand, species such as the Great auk, the passenger pigeon, and Steller's sea cow have no doubt that they are extinct and no sightings have been reported for a century or more.
Here is one reference for insect sampling and potential declines: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7069279/

I've just spent the last 3 hrs searching for information about dried Santolina species and their ability to repel moths, especially the greater and lessor wax moth and their larvae.
I've also looked for information about the possible toxicity of dried Santolina species on bees.
Good info is hard to find. There is info saying Santolina species repel silverfish and clothes moths but everyone copies everyone and there is little science behind it.
I'm wondering if I can use dried Santolina species inside my weak beehives, to help them resist wax moth.
Has anyone seen what I'm looking for or perhaps done the research themselves? Or has anyone seen another plant I could grow and use for this purpose?
Failing that, is anyone interested to take on this as a research project?

Sergey Viktorovich Pushkin right statements. It really depends on the age of the samples. During my PhD thesis, I was dealing with old alcohol arthropods with an age of 15 to 30 years and it was impossible to extract DNA from them as I was really eager to do that. Instead I used a DNA extraction method to clear these specimens to inspect them under microscope for accurate identification for further biodiversity calculations. Just check the link below:

Dear Erin Krichilsky I'm just wondering why you are looking for "a journal that accepts publications in two languages or at least is bilingual friendly". What is it good for to publish in different languages? We used to publish our research papers in German back in the 1970's and 1980's, but then we realized that the papers were not read by many researchers abroad. Then we switched to English to make sure that our papers are read worldwide (and eventually cited).

I will be working on stream amphibians in Sichuan in 2020, and part of the work will focus on the diet of some aquatic species and prey availability. I thought I'd identify macroinvertebrates with a key to North American or European aquatic macroinvertebrates, but I would like to use the closest key possible to avoid possible mistakes.
I don't know precisely to which taxonomic level I can identify available preys and prey items, certainly to Order, and hopefully to Family with intact invertebrates from the streams. I trained with North American Plecoptera and Odonata from France under a microscope, and it seems reasonnable that I could go as far as Family level with an adequate key.
Another way of putting the question can be : do you think I can identify these prey items and intact insects to order or family level with a key to macroinvertebrates from North America or Europe ?
Thanks in advance !

Ethanol and propylene glycol are both used to preserve mites, and each have their drawbacks (i.e., evaporation and specimen distortion). Some people add a small amount of glycerol to vials of ethanol to prevent samples from drying out over time if containers prove less than perfectly airtight. Does anyone have experience with the long-term performance of ethanol/propylene glycol mixtures as preservatives for mites, and particularly for oribatids?
Relevant answer
Answer
Dear Kara,
The usual concentration for ethanol is 70%. The more percentage makes specimens fragile in long-term even in short-term. About propylene glycol, I should say it may not go to the bottom of vials and it helps to reduce the evaporation of ethanol.
