Enhanced Attraction of <I>Plutella xylostella</I> (Lepidoptera: Plutellidae) to Pheromone-Baited Traps With the Addition of Green Leaf Volatiles

Antennal Sensillum Morphology and Electrophysiological Responses of Olfactory Receptor Neurons in Trichoid Sensilla of the Diamondback Moth (Lepidoptera: Plutellidae)

“…The presence of ORNs highly specialized for detecting green leaf volatiles with the highest sensitivity to 1-hexanol and (Z)-3-hexenol is in part corroborated by EAG recordings reported by Dai et al (2008) and Li et al (2012). Some other non-alcohol green leaf volatiles such as (Z)-3-hexenyl acetate and (E)-2-hexenal, which were shown to be behaviorally active in P. xylostella (Dai et al 2008, Li et al 2012, did not elicit any responses from the ORNs present in the trichoid sensilla examined in this study. It is likely that ORNs specifically for this compound are present in other non-trichoid sensilla such as sensilla coeloconica and sensilla auricillica in P. xylostella.…”

“…Research on insect-host interactions, particularly the host volatile organic compounds (VOCs), has flourished in recent decades, whereby knowledge of VOCs not only has benefited our fundamental understanding of plant-insect interactions, but also allowed the development of some plant-derived chemicals that are used for insect pest management (Dickens 2000;Light et al 2001;Li et al 2012).…”

An antennae‐enriched carboxylesterase from Spodoptera exigua displays degradation activity in both plant volatiles and female sex pheromones

“…For example, in Noctuidae acetates constitute ∼40% of the total sex pheromone components identified (Dong et al ., ). Additionally, many ester volatiles emitted by living plants are important clues for moths to locate their hosts, and some of the volatiles, such as (Z)‐3‐hexenyl acetate could enhance male attraction of the female sex pheromones in Spodoptera exigua (Deng et al ., ), Plutella xylostella (Li et al ., ) and Manduca sexta (Allmann et al ., ). Studies of enzymes active with ester odorants are particularly important, not only for the clarification of the enzymatic inactivation of odorant signals, but also for the development of ODE‐based strategies in pest management.…”

Semiochemical modulation of host preference of Callosobruchus maculatus on legume seeds

“…Several studies have showed that VOC blends are more attractive to insects than individual components (Kessler and Baldwin, 2001;McComic et al, 2012;Hammack, 2001;Siderhurst and Jang, 2010;Beck et al, 2012;Li et al, 2012), and VOCs that are not attractive individually may contribute to olfactory contrast that enhances attraction to the most active compounds in a blend (D'Alessandro et al, 2009). However, there are a few examples of a single compound attractant for many insect species including z-3-hexenylvicianoside that attracts predatory insects to tomato pests (Mescher and De Morales, 2014), dipropyldisulfide attracts flies to onions (Dindonis and Miller, 1981), and isothiocyanate that attracts crucifer-feeding insects (Vincent and Stewart, 1984).…”
