Population Genomics of Polistes Wasps
… genomic data set for primitively eusocial paper wasps in the genus Polistes. The third chapter of the thesis uses the dataset generated in chapter two to estimate patterns of natural selection on the Polistes genome, and to evaluate the importance of novel and caste biased genes on the fitness of …

After all, what do wasps want? The choice of sexual partner in the paper wasps Polistes
… of recessive deleterious alleles. Social paper wasps like Polistes fit this situation, but surprisingly little is known about how sexual selection operates in this taxon. Here, we examine proximal and ultimate causes involved in the choice of sexual partner in Polistes paper wasps. We conducted …

The Effects of Urban Land Use on Wasps (Hymenoptera: Apocrita)
… study examines the role of insects, specifically wasps, in urban gardens and vacant lots in Cleveland, Ohio. This study is intended to (1) provide a broader survey of Hymenoptera in an urban context; (2) provide new information on diversity and distribution of parasitoid Hymenoptera; (3) assess …

BEES AND WASPS IN A CHANGING ENVIRONMENT: MULTIPLE RESPONSES TO ANTHROPISED LANDSCAPES
Bees and predatory wasps provide highly relevant ecosystem services, the former being the main pollinator group and the latter regulating arthropod populations. Anthropisation, the way in which human activities shape natural ecosystems, threatens these insects from the community to the individual …

Understanding Virulence Mechanisms of Parasitoid Wasps of Drosophila: A Comparative Approach Across Clades
… species encapsulate parasitoid wasps’ eggs to inhibit wasp development. Parasitoid wasps of the genus <em>Leptopilina</em> are known to produce extracellular vesicle (EV)-like secretions in their venom. Well-characterized in <em>L. heterotoma</em>, these vesicles kill host …

Phylogeny of parasitic wasps of Torymidae (Hymenoptera: Chalcidoidea) and evolution of their life-strategies
The thesis is focused on phylogeny of the family Torymidae (Hymenoptera: Chalcidoidea) and evolution of their life-strategies. The study consists of general introduction to the phylogeny and classification of the family Torymidae chapter, four published papers in international journals and one …

The endocrinology and evolution of tropical social wasps: from casteless groups to high societies
… and behavior of three social vespid wasps was studied in northeast Brazil (São Cristóvão, Sergipe) from 2010-2011. There were two main objectives of this work: to test a hypothesis on the origin of reproductive castes (i.e. queen and worker phenotypes) in a communal species (Zethus …

Space in Aristophanes: Portraying the Civic and Domestic Worlds in Acharnians, Knights, and Wasps
… space in Aristophanes' Acharnians, Knights, and Wasps, and the comedies' attitude towards a variety of domestic and civic spaces, taking into consideration the cultural context in which the plays were composed. I argue that by using visual creativity and the available staging resources, …

Integrating Molecular, Ecological and Morphological Data to Explore the Biodiversity of Microgastrine Parasitoid Wasps
… genitalia and ecology of female microgastrine wasps. The morphology of the insect ovipositor apparatus is often functionally constrained for females and strongly correlated with and convergent on feeding behavior of its host caterpillars. Discriminant analysis found that male genitalia shape …

Comparative Physiological and Genomic Analyses of Division of Labor in Honey Bees and Paper Wasps
… castes. Expression patterns of individual wasps were predictive of behavioral state with a high (up to 80%) rate of success. In addition, I found 34% of genes to be associated with differences in wasp foraging state. In summary, I have demonstrated shared patterns of physiological and …

Nutritional status influences behavior, physiology, and brain gene expression in primitively eusocial Polistes metricus paper wasps
… of foraging trips per day for individual starved wasps was also significantly higher than for fed wasps. Starvation also caused a slightly significant increase in the proportion of foragers in a colony. At the physiological level, individuals from starved colonies had significantly lower abdominal …

The Influence of Weeds Associated With Reduced-Tillage Corn on a Black Cutworm Parasitoid, Meteorus Rubens (Nees Von Esenbeck), and Computer Simulation of The Consequences for Black Cutworm Damage
… 7.6 days, more than twice as long as starved wasps. Total parasitism and reproduction, 12.3 hosts and 164.7 offspring per wasp respectively, were also more than twice as great in nectar-fed wasps. In the field, wasps were visible in cages ca. 50% longer when flowering weeds were present, 6.1 …

Phylogeny and codivergence in the fig-fig wasp mutualism : sycoecine and agaondid fig wasps (Chalcidoidea, Hymenoptera) associated with Ficus section Galoglychia (Moraceae)
The interaction between figs and figs wasps is idealised as a classic example of coevolution through codivergence and cospeciation. Traditionally, the mutualism has been distinguished by a one-to-one ratio of host-specificity, whereby each species of fig tree (Ficlls, Moraceae) is pollinated by a …

Wasps (Hymenoptera: Chalcidoidea) associated with galls in seed-capsules of Eucalyptus camaldulensis (Myrtaceae) in South Africa : species composition, trophic relationships and effects
… the presence of two species of chalcidoid wasps, both regarded as gall inducers, in the seed capsules of E. camaldulensis in South Africa. The current study was motivated by the need for information on the biology of these two species and the effect they were having on seed production in …
