Virus morphogenesis of Helicoverpa armigera nucleopolyhedrovirus in Helicoverpa zea serum-free suspension culture

open access: yesJournal of General Virology, 2000
Helicoverpa armigera single nucleopolyhedrovirus (HaSNPV) replication in Helicoverpa zea serum-free suspension culture was studied in detail and the sequence of virus morphogenesis was determined by transmission electron microscopy.

Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

open access: yesPest Management Science, EarlyView.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...
