The western tarnished plant bug, Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of fruit, vegetable, and field crops in the western United States, but many aspects of L. hesperus ecology are poorly documented. A sound understanding of oviposition behavior and characterization of the phases of embryonic development would be useful in studies of interactions between L. hesperus and its ...

The selection of an appropriate oviposition site is crucial to the maternal fitness of eggraft producing mosquitoes. Females in this group of mosquitoes produce a single egg-raft during their lifetimes. All egg-raft producing mosquitoes are members of the subfamily Culicinae and include the medically important genera Culex and Culiseta. Egg-raft producing mosquitoes use several physical and che...

Mechoris ursulus (Roelofs) (Coleoptera: Attelabidae) is a pest weevil of Fagaceae oak trees in eastern Asia. The female has a distinct branch-cutting behavior in conjunction with oviposition in the acorns of its host plant. This study analyzed the factors influencing oviposition preference by carrying out continuous field surveys over the course of 2009-2010 and through laboratory rearing. The ...

Teleost v1r-related ora genes constitute a small and highly conserved olfactory receptor gene family, and their direct orthologs are present in lineages as distant as cartilaginous fishes. Recently, the first member of the ora gene family was deorphanized. ORA1 detects p-hydroxyphenylacetic acid with high sensitivity and specificity. This compound elicits olfactory-mediated oviposition behavior...

Artificial light at night (ALAN) is a pervasive and growing issue worldwide. ALAN disrupts the physiology natural crepuscular nocturnal behavior of organisms, with widely observed effects on insects. Mosquitoes (Diptera: Culicidae) are disease vectors that evaluate select freshwater habitats as oviposition sites. This has both ecological epidemiological implications. However, it unknown how aff...
