Molecular Basis of Pheromonogenesis Regulation in Moths
Chapter 8 Molecular Basis of Pheromonogenesis Regulation in Moths J. Joe Hull and Adrien Fónagy Abstract Sexual communication among the vast majority of moths typically involves the synthesis and release of species-specifc, multicomponent blends of sex pheromones (types of insect semiochemicals) by females. These compounds are then interpreted by conspecifc males as olfactory cues regarding female reproduc- tive readiness and assist in pinpointing the spatial location of emitting females. Studies by multiple groups using different model systems have shown that most sex pheromones are synthesized de novo from acetyl-CoA by functionally specialized cells that comprise the pheromone gland. Although signifcant progress was made in identifying pheromone components and elucidating their biosynthetic pathways, it wasn’t until the advent of modern molecular approaches and the increased avail- ability of genetic resources that a more complete understanding of the molecular basis underlying pheromonogenesis was developed. Pheromonogenesis is regulated by a neuropeptide termed Pheromone Biosynthesis Activating Neuropeptide (PBAN) that acts on a G protein-coupled receptor expressed at the surface of phero- mone gland cells. Activation of the PBAN receptor (PBANR) triggers a signal trans- duction cascade that utilizes an infux of extracellular Ca2+ to drive the concerted action of multiple enzymatic steps (i.e. chain-shortening, desaturation, and fatty acyl reduction) that generate the multicomponent pheromone blends specifc to each species. In this chapter, we provide a brief overview of moth sex pheromones before expanding on the molecular mechanisms regulating pheromonogenesis, and con- clude by highlighting recent developments in the literature that disrupt/exploit this critical pathway.

The results of this study make clear the importance of palynology at the time of establishing the diet of these species, in addition to reflect its role of those species as possible provider in ecosistemic services either in wild plant as a crops in Solanaceae case.

Electronically produced using Free Software and in accomplishment with an Open Access spirit for academic publications Social behaviour in ants of the genus Leptothorax is reviewed. Attention is paid to the existence of collective robust periodic oscillations in the activity of ants inside the nest. It is known that those oscillations are the outcome of the process of short-distance interactions among ants and that the activity of individual workers is not periodic. Isolated workers can activate spontaneously in a unpredictable fashion. A model of an artificial society of computer automata endowed with the basic behavioural traits of Leptothorax ants is presented and it is demonstrated that collective periodic oscillations in the activity domain can exist as a consequence of interactions among the automata. -

The virus may also be detected in other insect species, including Bombus terrestris adults from wild and managed colonies. In this study, individuals of all stages, castes, and sexes were sampled from three commercial colonies exhibiting the presence of deformed workers and analysed for the presence of DWV. Adults (deformed individuals, gynes, workers, males) had their head exscinded from the rest of the body and the two parts were analysed separately by RT-PCR. Juvenile stages (pupae, larvae, and eggs) were analysed undissected. All individuals tested positive for replicative DWV, but deformed adults showed a higher number of copies compared to asymptomatic individuals. Moreover, they showed viral infection in their heads. Sequence analysis indicated that the obtained DWV amplicons belonged to a strain isolated in the United Kingdom.

Associations Between Birds and Social Wasps in the Pantanal Wetlands

ABSTRACT: Nesting associations between birds and wasps may increase reproductive success of birds because the stings of these insects serve to protect the offspring against predators. The predation of wasps by birds is known from elsewhere and usually birds feed on the wasps during flight. Here we report on nest associations between birds and social wasps and comments on wasp nest predation by birds in the Brazilian Pantanal wetlands. The study was conducted in the sub-region known as “Pantanal de Poconé”, state of Mato Grosso, Brazil. We recorded seven associations involving four bird species: Paroaria capitata, Myiozetetes similis, M. cayannensis and Columbina talpacoti, and four wasp species: Polybia sericea, P. ruficeps xanthops, Chartergus globiventris and Parachartergus fraternus. One successful nest of M. cayannensis (14.2%) was associated to P. sericea wasps. On the other hand, 42.8% of the bird nests were abandoned, and 42.8% were preyed upon. Additionally, a direct event of wasp nest predation was recorded, in which a group of Melanerpes candidus attacked a nest of P. -
An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Sarah A. Maxfield-Taylor for the degree of Master of Science in Entomology presented on March 26, 2014. Title: Natural Enemies of Native Bumble Bees (Hymenoptera: Apidae) in Western Oregon Abstract approved: _____________________________________________ Sujaya U. Rao Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in these declines, believed to affect bumble bee colonies in the wild and during rearing, is natural enemies. A diversity of fungi, protozoa, nematodes, and parasitoids has been reported to affect bumble bees, to varying extents, in different parts of the world. In contrast to reports of decline elsewhere, bumble bees have been thriving in Oregon on the West Coast of the U.S.A.. In particular, the agriculturally rich Willamette Valley in the western part of the state appears to be fostering several species. Little is known, however, about the natural enemies of bumble bees in this region. The objectives of this thesis were to: (1) identify pathogens and parasites in (a) bumble bees from the wild, and (b) bumble bees reared in captivity and (2) examine the effects of disease on bee hosts. Bumble bee queens and workers were collected from diverse locations in the Willamette Valley, in spring and summer. Bombus mixtus, Bombus nevadensis, and Bombus vosnesenskii collected from the wild were dissected and examined for pathogens and parasites, and these organisms were identified using morphological and molecular characteristics. -

Journal of Hymenoptera Research 38: 135–139. doi: 10.3897/JHR.38.7763 Abstract Male behavior of Neotropical swarm-founding wasps has rarely been observed. The few published ob- servations about male activities only describe their behavior during the short period they spend inside nests. In consequence, virtually nothing is known about what they do outside the colonies, and even less is known about mating behavior. This paper provides the first report of Epiponini males arriving at a colony with virgin females. The behavior of males and workers after queen removal was observed in one colony of Chartergellus communis located at a farm in Pedregulho, São Paulo, Brazil. The day after queen elimination, males were observed outside the nest.
