Electroantennographic response and odorant-binding protein expression alterations induced by host plant volatiles in <i>Athetis dissimilis</i> (Hampson).

ABSTRACT: Athetis dissimilis is one of the main pests affecting crops, and is currently managed through chemical control methods. Plant volatiles can stimulate insects to feed and lay eggs. The investigation of plant volatiles and the development of effective attractants are essential for sustainable pest control. In this study, we examined plant volatiles using electroantennogram (EAG) analysis, and observed alterations in OBP expression in A. dissimilis. The EAG results indicated that the EAG responses for trans-2-hexenal, cis-3-hexen-1-ol, and trans-2-hexen-1-ol in male adults were the highest, measuring 1.35 ± 0.02 mV, 1.30 ± 0.10 mV and 1.27 ± 0.18 mV, respectively. This was followed by (E, E)-2,4-hexadienal (1.01 ± 0.06 mV), octanal (0.69 ± 0.04
