  • Carlos Marcondes added an answer:
    What statistical analysis should I use for measuring dispersal of insect vectors using mark–release–recapture techniques?

    I intend to study the dispersal pattern of phlebotomine sand flies in a forested area in the cerrado (savanna) biome of Northeastern Brazil. Human dwellings and domestic animals are commonly found in the area. What is the best statistical test that should be applied in the analysis? The insects will be trapped, marked with fluorescent dust and then released at different collecting points. I will try to recapture the phlebotomine sand flies in the next ten days. I want to gather information about dispersal range, spatial memory, host fidelity, site fidelity and longevity. Can you help me?

    I would suggest you to download Service's book on Mosquito Ecology (3rd edittion) from Springer site. I have done this, and it seems to have information at least in chapters 14 and 15.

    Is it possible that drywood termite use chemicals on fecal pellets for intra-colony communications?

    As individuals of drywood termite colony are distributed on different position inside nest-gallery, how do they "attract" nest-mate or inform their presence in certain chambers?

    S. Khoirul Himmi · Indonesian Institute of Sciences

    Thank you very much for your answer.

    But I think those communication traits using fecal pellets you mentioned were mostly found in higher termites. Do you have any suggestive references, specifically refer to drywood termite, or, at least fellow one-piece nesters

    Any experiences, comments or suggestions on insect monitoring?

    We are organising insect diversity monitoring networks in China. 

    I just drafted the talk to present on the 1st Biodiversity Monitoring Conference, China. All texts are in Chinese at the moment. http://blog.sciencenet.cn/blog-536560-860261.html 

    If you have any interests, comments or suggestions, please kindly contact me. Certainly, you are welcome to discuss on potential collaborations.

    For many years, we have used photovoltaic powered light traps for the nocturnal insect fauna in agricultural regions far away from electricity supply. The development of these traps was done at the technical University at Aachen Juelich, in Germany, by L. Wagner & A. Neskakis, 1994. If you are interested I can send you more details and contacts. 

  • Nick Stewart added an answer:
    Can anyone suggest peer-reviewed articles(s) noting the spread of Osmia taurus in Eastern US - especially as it relates to its southerly migration?

    Since the unintentional Nearctic introduction of O. taurus to the Mid-Atlantic in the 1970's, the species has been spreading - colonizing & naturalizing as it goes. While mostly recorded spreading due-West & North-East along the coast from its original landfall to date, Georgia now marks the most southerly progression of the species. Both its adaptability to the environs of the Eastern US, as well as its remarkable population growth once present, should be of note for both researchers and farmers. 

    To track the progression of Osmia taurus into the Deep South, I would really appreciate any peer-reviewed literature which identified O. taurus outside its suspected original Mid-Atlantic port-of-call - most importantly South of the Mason-Dixon (anywhere from MD through WV, VA, KY, TN, SC, NC...).

    ** Also, any papers like those requested above - but pertaining to the presence of Osmia cornifrons & Anthidium manicatum - would likewise be very much appreciated!! **

    Nick Stewart · Georgia Gwinnett College

    Dr. Biddinger,

    You said in response to my initial question that: "I was told while in some meetings in S. Korea that it [O. taurus] might be a bit of a social parasite of O. cornifrons since the Japanese website on cornifrons lists it as harmful/parasitic."

    What website can that be found on &/or do you have any published sources mentioning that? 

  • Nikolaus Szucsich added an answer:
    Does anyone do research with insects on Castanea sativa?

    I would like to know some information about species diversity of insects on Castanea sativa  or C. crenata, C. dentata. It should be mainly beneficial species which eat or collect pollen during blooming period or rare species.

    I will be grateful for any information about this issue.

    Nikolaus Szucsich · Naturhistorisches Museum Wien

    Hello Michal

    Most works deal with pests on Castanea (like "Insects Feeding on The Sweet Chestnut (Castanea sativa Mill.) in Bulgaria"), but there are some studies on pollinators

    you can look for: de Oliveira D, Gomes A, Ilharco FA, Manteigas AM, Pinto J, Ramalho J. 2001. Importance of insect pollinators for the production in the chestnut, Castanea sativa. Acta Horticulturae 561: 269–273

    Dear Joanna Zalewska Gałosz,

    After choosing a format or adopting one according to journal guideline, try using KML file format for the points.

    It is a useful format which allows one to easily map the points.

    You can use both coordinates formats in a KML file.

  • Where is Megasoma mars distributed?

    We have collected male and female Megasoma mars in Paraguay, however, scarce information from the web suggests a different distribution range. I would appreciate any information regarding this species as well as sources of information to contrast. Both specimens were found dead in forest islets and with almost five years apart when found them. I also attached two pictures in case this might be a case of wrong identification.

    Karim Musálem-Castillejos · Centro de Investigación del Chaco Americano, Paraguay

    I have contacted a researcher specialist about this issue, and has very kindly helped me. He has indeed corrected the identification to Megasoma janus janus, and has provided with a picture for M. mars to notice the differences (mostly in the horns). M. janus is indeed distributed in Southern Brazil and Paraguay.

  • Timothy A Ebert added an answer:
    Does anyone has experience on developing an automated counter for insect census?

    To develop a program inside the device

    Timothy A Ebert · University of Florida

    Ah, that is better. The radar system works for flying insects, as might the photonic fence. I have used a camera and Image Pro Plus to analyze for pesticide deposits on a leaf surface. The biggest problem is contrast. However, bag worms are large (relative to pesticide deposits) and are usually darker than the leaf surface. However, the leaf would probably have to be back lit to maximize contrast.

    If the bagworms do not leave the plant when the larvae are mature it may be difficult to determine if the bagworm is still alive.

  • Nyonka Vuchkova Velcheva added an answer:
    How do I determine if a moth specimen has never been found in the state or county before?

    I found adult moths, caterpillars, and pupa of the Lantana Stick Moth (Neogalea sunia) on a Lantana plant in Sacramento County, in California. Range information shows this as a first record of this species in California. Where can I go to find out if this is really the first recorded time this moth has been found in California, or at least in Sacramento County? If this is a first appearance for the state or county, how do I and should I report this pest? I have live caterpillar specimens, live cocoons, and a dead moth specimen.

    Nyonka Vuchkova Velcheva · Agricultural Academy - Bulgaria

    Found the gentalii of male on http://www7.inra.fr/papillon/noctuid/noctuide.htm and check you moth. Threre are many papers about this species in Internet.

  • Does anyone know where can I get relative air humidity data for South America?

    I'm trying to model the distribution of a species of fly, so I used the Bioclim data from Worldclim.org. The problem is that relative humidity plays an important role in insects distribution and I can't find the data for it anywhere.

    Is there any place where I can download it?

    Thanks in advance

  • Steve W Wilson added an answer:
    Do you have any experiences on the spread and damage of Metcalfa pruinosa (Flatidae) in your country?
    Citrus flatid planthopper, a native insect to North America, have had for a long time a scarce economic importance there. However, being polyphagous made small damage on citrus trees and some ornamentals. In 1979 it was introduced to Italy where it established and spread quickly. It is now an invasive alien species (IAS) continually spreading in South and Central Europe causing considerable damage in grapevine, fruit trees and various ornamentals.

    In Hungary M. pruinosa causes damage - as in other European countries - in grapevine, fruit and other ornamental trees and shrubs. Unfortunately, it spreads in semi-natural and natural areas like hedges. I have observed nymphs, adults and vaxy filaments of M. pruinosa on the majority (70%) of the trees and shrubs in a hedge.

    Infested plants – among them some with American origin – were: Acer negundo, Celtis occidentalis, Clematis vitalba, Crataegus monogyna, Hedera helix, Juglans regia, Lycium barbarus, Malus domestica, Morus alba, Prunus domestica, Prunus padus, Prunus serotina, Prunus spinosa, Robinia pseudo-acacia, Rosa canina, Ulmus campestris but also Euphorbia cyparissias.

    The length of similar hedges can be several hundred km long, which means M. pruinosa has plenty of opportunity for spreading along the railway and infesting agricultural and ornamental cultures.

    Where and on which vegetation have you observed this IAS? How much important damage have you detected?

  • Michał Bogdziewicz added an answer:
    What method would you recommend to count weevils on sites?

    Hi all,

    I would like to compare and abundance of weevils on two sites to learn if the increased weevil infestation of acorns is due to differences in abundance of those insects. Thus, I need some index of abundance. I have not yet worked with weevils yet so I am not sure what kind of method should I use.

    I read on the Internet about weevil traps and I found for example traps like that:

    http://www.iscatech.com/ecommerce/index.php?main_page=product_info&cPath=24_1&products_id=22

    Maybe installing them on trees in autumn and then couting catched indivuduals in spring will work? Or maybe I could even install them now and get and index of abundance this year?

    I am doing my research on red oaks in eastern US.

    Anyone who has any experience with the subject - please share!.

    How can I determine the population of mosquitoes?

    I am working in an area and have caught some mosquitoes over a period of time? How can i determine the population of mosquitoes in the location and in the state in general? Is there any formula I can use, please how do I go about it?

    Ayman Ahmed · US Naval Medical Research Unit-3

    As Mr. Renaud said you have to go with Mark-Release-Recapture, which you have to mark known number  of Mosquito with fluorescent dye, and release them at the targeted area and give them time to get homogenized with wild population, and recapture mosquito and sort the harvest to marked and wild mosquitoes and use the equation to estimate the population size. for details :-

  • András Bozsik added an answer:
    What could be the interest to include some parasitoid species (like some Hymenoptera Braconidae) into the Redlist of IUCN?

    Threatened insects are not so common and nearly none of them are parasitoids.

    But some of the parasitoids species could probably also be considered as threatened because their high specialization to one or few hosts, their distribution (a lot of species of Braconidae are known only from few specimens or few places, even if this could be a bias of sampling) or their presence in threatened area (like rain forests).

    Is this opportunity could help to their studies or the conservation of several areas/ecosystems? Did you have information, ideas, papers, example of such cases?

    András Bozsik · University of Debrecen

    Dear All,

    The lectures in York may be interesting but cannot influence either the saving of parasitoids or their recognitions. Most of parasitods belong to the order Hymenoptera which are enormously difficult to identify. Unfortunately, majority of growers has no idea on natural enemies. Many of them use blindly pesticides.

  • In which country are insects the most popular human food and what kinds of insects?
    In Western Kenya, termites are a delicacy.
    Eduardo Goncalves Paterson Fox · University of Lausanne

    People should always be reminded that insects are regularly consumed in food in all countries as an inevitable outcome of agriculture and storage and exposure of goods until consumption, particularly remains of eggs and larvae. If one is young, lives in a really cold country and totally avoids vegetables, there might be a chance that this person has yet never eaten any insect. Regarding accidental consumption of insects, I would assume that residents of tropical and subtropical regions must have the highest inadvertent rates of entomophagy.

  • Ranjith Raveendran added an answer:
    Who knows a good place in the southern US where Microplitis croceipes can be collected on the field?
    If possible, in AL, GA, MS, TN, FL
    Ranjith Raveendran · University of Calicut
    Microplitis croceipes (Cresson) 1872, is a potential parasitoid of Helicoverpa zea Boddie, 1850 (Corn worm) and Heliothis virescence Fabricius, 1777 (Tobacco bud worm). If there is Corn field and Tobacco plants in Southern US you can easily see the Host larvae and try to collect the larvae and starts to rear it. This parasitoid is specific for those host larvae.
  • Anya Nova Metcalfe added an answer:
    Is anyone familiar with the larval stage of Cisthene moths (Arctiidae)?
    Can the caterpillars be found in bio soil crusts? I collect adult Cisthene angelus by the thousands along the riparian corridor of the Colorado River in Grand Canyon National Park, but their caterpillars are nowhere to be found. There's not a ton of lichen throughout the river corridor, it depends on which rock layers are exposed (seems like the lichen is mostly on limestones). What can you tell me about these elusive caterpillars? Where have you found them?
    Anya Nova Metcalfe · United States Geological Survey
    Christian - I will keep this in mind and look for tree lichens on my next trip down Grand Canyon. There are not too many trees in the riparian zone, I'm going to check the mesquites and cat claw acacias in the old high water zone for lichens. Do you have any further advice for finding them? Will the caterpillars be easiest to spot with white or UV light? Do you know of anything they are attracted to? Are the eggs large enough to be seen with the naked eye?

    Sorry for the bombardment of questions. Thanks so much for your response!
  • Muhamad Ikhwan Idris added an answer:
    Why are lowland forests insect species more diverse than in the highland forests?
    The lower the elevation, the more diverse the insect species are than those living in places at higher altitude.
    Muhamad Ikhwan Idris · University Malaysia Sarawak
    Highland forest can be regarded as an habitat island (surrounded by different kind of habitat due to its altitude). The land area doesnt necessary (or guaranteed) to have a higher number of species. Numbers of habitat that present in one particular (even though it's smaller) could lead to a higher number of diversity compared to a bigger area with less types of habitat.

    It's all governed by the plant species and distribution. Since many plants can adapt to lower altitude, many plants could be found thus leads to many species of insects (provided that they might be specialist). However, those which could adapt to the highland forest could be unique and cant be found elsewhere.

  • Paride Dioli added an answer:
    Any ideas or suggestions about the passive transport of insects on highways by windage?
    Working on the spread of Lygaeus creticus (Heteroptera) I suggested that the median of the highway, which is made ​​up of oleander, has transferred this species from southern to northern Italy. It seems that even windage operated by heavy goods vehicles has a significant impact. I'm checking out the possibility that this hypothesis is applicable to other species of insects and am looking for references in Literature.

  • Peter Hondelmann added an answer:
    Have any one encountered fruit flies (Tephritidae) flying (or drifting) at high altitude?
    I am interested in migration pathways of fruit flies in general and Medfly in particular. Medfly tend to reappear “out of the blue” in certain places without living a clue to where they came from and how. Many insects are flying quite high when crossing long distances, and I guess so are the tephritids. So I guess this question is mainly addressed to aerobiologists who are practicing different approaches to detect flying insects.
    Peter Hondelmann · Leibniz Universität Hannover
    There are surprisingly many publications about "aerial plankton" such as "Studies in the distribution of insects by aerial currents" by Hardy & Milne (1938), Hardy & Cheng (1986) (with three parts) at least mentioning Drosophilidae in the first one, but I've no access to the others. Anyway they contain family and species lists. "Transoceanic dispersal studies of insects" by Holzapfel & Harell (1968) mentions Trypetidae in their catches,
    Also "THE DISTRIBUTION OF INSECTS, SPIDERS, AND MITES IN THE AIR" by Glick (1939) lists Trypetid species. So you have your answer (but medfly?).
    If you search for aerial plankton and Trypetidae (the older name for Tephritidae) you surely find more articles, since many of the studies were done before 1990.
