六种植物挥发物对不同日龄梨小食心虫成虫触角电位反应的影响
Effects of six plant volatiles with different dosages on electroantennogram responses of oriental fruit moth Grapholita molesta at different adult ages
摘要
Abstract
To elucidate the interaction between the dosage of plant volatiles,age and mating status of oriental fruit moth Grapholita molesta,the electroantennogram(EAG)responses of female adult G.mo-lesta at various ages to five different doses of six plant volatiles were measured.The results showed that a significant interaction effect between age and dose was observed in the EAG responses of female G.molesta to four volatiles:benzaldehyde,benzonitrile,nonanal and farnesene.The EAG response of G.molesta to volatiles at a fixed dose gradually increased with age,stabilizing after five days.When G.molesta was five days old,an interaction between mating status and dosage was observed in the EAG responses to benzaldehyde and cis-3-hexenyl acetate.Decanal elicited higher EAG responses in mated females than in unmated ones across all treatments.As the dosage increased,the EAG responses of mat-ed females to farnesene and nonanal significantly increased.Unmated G.molesta females exhibited the highest EAG responses to benzaldehyde(0.01 μg/μL and 0.1 μg/μL)and cis-3-hexenyl acetate(1,10 and 100 μg/μL),while mated females showed the highest EAG responses to benzonitrile(0.01 μg/μL),nonanal(0.1 μg/μL and 1 μg/μL),cis-3-hexenyl acetate(10 μg/μL),and decanal(100 μg/μL).These re-sults indicate that the age and mating status of G.molesta crucial factors influencing their EAG respons-es to host plant volatiles.关键词
