Article
Ants intercepted by the Hawaii Department of Agriculture in 2018 and 2019 identified as Solenopsis spp., and possibly S. invicta, were submitted to the United States Department of Agriculture-Agricultural Research Service-Center for Medical, Agricultural and Veterinary Entomology, Imported Fire Ant and Household Insects Research Unit for further ta...
Article
Full-text available
Emerging evidence shows that the cuticular and silk lipids of spiders are structurally more diverse than those of insects, although only a relatively low number of species have been investigated so far. As in insects, such lipids might play a role as signals in various contexts. The wasp spider Argiope bruennichi has probably the best investigated...
Article
Full-text available
South American fire ants, Solenopsis richteri and Solenopsis invicta , were accidently introduced into the southern USA in the 1900s and 1930s, respectively. The rapid spread and high population densities of S. invicta , and its potent sting, resulted in broad economic impacts and a variety of research efforts. In the 1970s, their venom alkaloids w...
Article
Full-text available
Social insect queens have evolved mechanisms to prevent competition from their sexual daughters. For Solenopsis invicta , the fire ant, queens have evolved a primer pheromone that retards reproductive development in their winged reproductive daughters. If these daughters are removed from the influence of the queen, it takes about a week to start re...

Methods for killing insects (eg, Drosophila species such as Drosophila suzukii), involving treating an object or area with an insect (eg, Drosophila species such as Drosophila suzukii) killing effective amount of a composition containing at least tyramine and/or N-methyl-tyramine, optionally a phagostimulant (eg, sucrose), optionally food material...

Patent
The present invention provides novel compositions and methods for using the insect neuromodulator tyramine and/or one or more derivatives thereof delivered to insect populations to control certain aspects of such populations. The amount of tyramine and/or one or more derivatives thereof delivered on a per insect basis is significantly greater than...
Article
Animals change sensory responses and their eventual behaviors, depending on their internal metabolic status and external food availability. However, the mechanisms underlying feeding state-dependent behavioral changes remain undefined. Previous studies have shown that Caenorhabditis elegans hermaphrodite exhibits avoidance behaviors to acute exposu...
Article
Experiences during early development can influence neuronal functions and modulate adult behaviors [1, 2]. However, the molecular mechanisms underlying the long-term behavioral effects of these early experiences are not fully understood. The C. elegans ascr#3 (asc-ΔC9; C9) pheromone triggers avoidance behavior in adult hermaphrodites [3–7]. Here, w...

Full-text available
Insect vectors are required for the transmission of many species of parasitic nematodes, but the mechanisms by which the vectors and nematodes coordinate their life cycles are poorly understood. Here, we report that ascarosides, an evolutionarily conserved family of nematode pheromones, are produced not only by a plant-parasitic nematode, but also...

Article
The analysis of cuticular extracts from the cleptoparasitic spider Argyrodes elevatus revealed the presence of unusual esters, new for arthropods. These novel compounds proved to be methyl-branched long chain fatty acid esters with methyl branches located either close or remote from the internally located ester group. GC/MS analysis of the prosoma...

Full-text available
Males of many spider species risk being attacked and cannibalized while searching for, courting, and mating with conspecific females. However, there are exceptions. We show that the funnel-web spider, Hololena curta, has three adaptations that minimize risk to males during courtship and mating, and enhance reproductive success. First, males detecte...

Significance Many free-living and parasitic nematode (roundworm) species use pheromones called ascarosides to control their development and behavior. The molecular mechanisms by which environmental factors influence pheromone composition are unknown. The side chains of the ascarosides are derived from long-chain fatty acids that are shortened throu...

AbstractA variety of signals mediate reproductive behaviors of Tephritidae, and studies of such behaviors have focused predominantly on economically important tephritid pest species. Trupanea vicina (Wulp) (Diptera: Tephritidae: Tephritinae), an Asteraceae‐feeding fruit fly, was not considered a pest until recently, when large populations developed...
Article
Mealybugs are widely distributed pests of numerous agricultural crops and ornamental plants. In addition to causing direct damage, they are known vectors of plant pathogens such as grape leafroll viruses. The identification and several alternate syntheses of the irregular terpenoid pheromones of three important mealybug species (obscure, longtailed...
Article
The trienoic and tetraenoic polyenes, (3Z,6Z,9Z)-3,6,9-nonadecatriene, (3Z,6Z,9Z)-3,6,9-henicosatriene, and (3Z,6Z,9Z)-1,3,6,9-henicosatetraene were found in the abdominal cuticle and pheromone gland of the winter moth Operophtera brumata L. (Lepidoptera: Geometridae), in addition to the previously identified single component sex pheromone (3Z,6Z,9...

As a result of relaxation of importation restrictions ordered by the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture, shipments of fresh avocados from Mexico began entering California year-round in 2007, despite the fact that these shipments were heavily infested with a number of exotic and potentially invasive armo...
Conference Paper
The invasive scale species Acutaspis albopicta (Cockerell) is a serious potential threat to avocado production in California and possibly other plants as it has a broad known host range. Because little was known about its basic biology, we examined several life history parameters. Female scales only reproduced sexually, with most females surviving...

Adults of the sorghum chafer, Pachnoda interrupta Olivier (Coleoptera: Scarabaeidae: Cetoniinae), form aggregations during the mating period in July, but also in October. The beetles aggregate on food sources, e.g., Acacia spp. trees or sorghum with ripe seeds, to feed and mate. During the mating season, field trapping experiments with live beetles...

Wespenspinne sucht Partner: Die Weibchen der Wespenspinne (siehe Bild) verwenden Methylcitronensauretrimethylester (siehe Struktur) als fluchtiges Sexualpheromon, um die Mannchen anzulocken. Auf einer sonnigen Wiese im Hochsommer gelang es erstmals, Spinnen mit Pheromonfallen zu fangen (Photo: Helen Sandford).
Article
(Figure Presented) Wasp spider looking for a mate: Female wasp spiders (see picture) use trimethyl methylcitrate as a volatile cue to attract males. The experiments were performed on a sunny meadow, showing for the first time that spider traps can be used to trap spiders in the field (photo: Helen Sandford).
Conference Paper
Spider webs and spider silk are well known vectors for chemical signals and help in the conceptual understanding of the spider behavior in communication and sexual interactions1. Only few pheromones have so far been identified from spiders, and no successful field application has been reported till date. Extracts of volatiles from virgin and mated...

We explore the role of chemical communication in spiders. Behavioural observations clearly demonstrate that male spiders are attracted to females from a far. We investigated the sexual pheromone of the wasp spider Argiope bruennichi whose biology we are particularly interested in since it shows strong sexual dimorphism, sexual cannibalism, alternative mating tactics and rapid range expansion (see related research topics on our homepage).
