Population Genomics of Polistes Wasps
… 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 this primitively …

After all, what do wasps want? The choice of sexual partner in the paper wasps Polistes
… 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 laboratory …

Nutritional status influences behavior, physiology, and brain gene expression in primitively eusocial Polistes metricus paper wasps
… behavior of primitively eusocial insects such as Polistes metricus paper wasp. This is an interesting consideration because if the related behaviors displayed by these two independently evolved social insects are mediated by similar pathways, it may give more insight into the evolution of …

Interakcje gospodarz – parazytoid na przykładzie Polistes nimpha (Christ, 1791) (Hymenoptera: Vespidae) i Latibulus argiolus (Rossi, 1790) (Hymenoptera: Ichneumonidae)
Praca dotyczy interakcji gatunku osy Polistes nimpha będącej gospodarzem parazytoida Latibulus argiolus. Badania prowadzono w latach 2012 – 2014, w okolicach Suchego Lasu, wykorzystując metodę cotygodniowych inwentaryzacji gniazd os oraz nagrywania zachowań klecanek oraz parazytoidów za pomocą …

The endocrinology and evolution of tropical social wasps: from casteless groups to high societies
… devoted to the study of wasp physiology beyond Polistes, a large genus of primitively eusocial paper wasps. In Polistes, juvenile hormone (JH) has been shown to be important for reproduction, dominance, chemical signaling (e.g., cuticular hydrocarbons (CHCs)) in queens while promoting the early …

Acquisition and Retention of Bacterial Spores (Bacillus Atrophaeus) by Eight Insect Species
… (Tenebrio molitor L.), common paper wasps (Polistes exclamans exclamans Viereck), red paper wasps (Polistes Carolina L.), red harvester ant (Pogonymyrmex barbatus Smith). Individual insects were offered BG-treated food and sacrificed at specified time intervals following one, two or three …

Cooperation And Competition In Paper Wasp And Human Societies
… I focus on the primitively eusocial wasp Polistes dominulus, as individuals display behavioral flexibility and benefit from investing in both cooperation and conflict. In chapter 3, I use field and lab experiments test theoretical predictions that P. dominulus may not face a simple …

Multi-faceted analyses of plant-pollinator interactions: From ecological communities to individual foraging decisions
… when visited once by a male paper wasp Polistes fuscatus compared to when a flower was freely visited by P. fuscatus and Bombus impatiens. Lastly, I used a matched field and individual-based model to determine how bees use past experiences to alter foraging behavior. I found the foraging …

Comparative Physiological and Genomic Analyses of Division of Labor in Honey Bees and Paper Wasps
… independently evolved sociality, the paper wasp Polistes metricus. I also found low abdominal lipid in P. metricus foragers. I then developed an EST project of sequences representing approximately 5000 P. metricus genes. I examined the expression of a set of 32 P. metricus orthologs to genes …

BEES AND WASPS IN A CHANGING ENVIRONMENT: MULTIPLE RESPONSES TO ANTHROPISED LANDSCAPES
… 1805) (Hymenoptera: Megachilidae), and the wasp Polistes dominula (Christ, 1791) (Hymenoptera: Vespidae). The field studies were preceded by a re-analysis of published data on wild bee communities in different cities around the world, which showed how highly urbanised areas filter for bee species …
