Chang Di et al.
Insect biochemistry and molecular biology, 84, 48-62 (2017-04-04)
Lepidopteran caterpillars rely on olfaction and gustation to discriminate among food sources. Compared to the larval gustation, the larval olfaction has been poorly investigated. To uncover the molecular basis of olfaction in Helicoverpa armigera larvae, we identified 17 odorant receptor
Wei-Chan Cui et al.
Insect biochemistry and molecular biology, 97, 31-39 (2018-04-27)
Plant volatiles are vital cues in the location of hosts for feeding and oviposition for Lepidoptera moths. The noctuid Helicoverpa assulta is a typical polyphagous moth, regarded as a good model for studying the olfactory reception of plant volatiles. In
