متن کاملThe plant sesquiterpene germacrene D specifically activates a major type of antennal receptor neuron of the tobacco budworm moth Heliothis virescens.
Plants release hundreds of volatiles that are important in interactions with insects or other organisms. However, knowledge is scarce as to which of the compounds are detected by the organism's olfactory receptor neurons. In the present study, single receptor neurons on the antennae of the tobacco budworm moth, Heliothis virescens, were screened for their sensitivities to naturally produced pla...
متن کاملCharacterization of esterases associated with profenofos resistance in the tobacco budworm, Heliothis virescens (F.).
The utility of microplate and electrophoretic assays for detection of biochemical and physiological mechanisms underlying resistance to profenofos in the tobacco budworm, Heliothis virescens (F.), was assessed. Esterase (EST) activities were significantly higher in profenofos-resistant than -susceptible larvae, and activities were highly correlated (r(2) = 0.87) with resistance to profenofos. B...
متن کاملPlasma phenoloxidase of the larval tobacco budworm, Heliothis virescens, is virucidal
Heliothis virescens larval plasma contains high levels of an antiviral activity against the budded form of the Helicoverpa zea single nucleopolyhedrovirus (HzSNPV) in vitro. Preliminary results indicated that phenoloxidase is primarily responsible for this virucidal effect. However it is known that other enzymes that generate antimicrobial reactive oxygen intermediates and reactive nitrogen int...
متن کاملFunctional characterization of pheromone receptors in the tobacco budworm Heliothis virescens.
Functional analyses of candidate Heliothis virescens pheromone odorant receptors (HvORs) were conducted using heterologous expression in Xenopus oocytes. HvOR6 was found to be highly tuned to Z9-14:Ald, while HvOR13, HvOR14 and HvOR16 showed specificity for Z11-16:Ald, Z11-16:OAc and Z11-16:OH, respectively. HvOR15, which had been considered a candidate receptor for Z9-14:Ald did not respond to...
