The studies presented here illustrate the value of the recently sequenced honey bee genuine for the expansion of our knowledge of insect evolution and physiology. In the first study, a novel lineage of insect opsins is ...

Culex pipiens was the only species collected from the Champaign-Urbana, overwintering site. Temperature was the key factor in resting site choice by these females, with most found in the coldest areas of the site throughout ...

The resource utilization patterns of native vernal bees visiting Salix (willows) were studied at a site in Champaign Co., east central Illinois during 1982-84. Hourly sweep collections of insects visiting willows and several ...

Pesticides are ubiquitous contaminants of the freshwater aquatic environment. Pesticide residues are found in varying amounts in all components of the aquatic ecosystem including water, animal and plant tissue and sediments. ...

Research on the chemical ecology of cerambycid beetles has revealed that the pheromone chemistry of related species is often highly conserved. Sympatric species often share pheromone components, even having identical ...

The objective of this study is to develop a framework for biological research on Thereva (1) using molecular data to test a phylogenetic hypothesis that posits a monophyletic Thereva with respect to a diverse sample of ...

Parasitoid wasps play a pivotal role in maintaining the structure and dynamics of complex food webs. However, classical species sampling techniques such as malaise, light and yellow pan trapping, generally lack information ...

Psocodea is an order of insects that includes parasitic and non-parasitic lice. The phylogenetic relationships of many groups have never been tested with phylogenetic methodology. Most species are small in body size and ...
