通过田间调查及行为反应、EAG反应和产卵选择性测定,研究了板栗挥发物对桃蛀螟(Conogethes punctiferalis)成虫寄主选择行为的影响.2004-2008年的田间调查结果表明:桃蛀螟在农大1号板栗上的蛀果率为16.1%~25.3%,而在河源油栗上的蛀果率均小于5%,桃蛀螟对前者的危害明显较重.农大1号板栗的果实和叶片挥发物对桃蛀螟雌蛾均有显著吸引作用,其中果实比叶片挥发物的吸引作用更强,但上述挥发物对雄蛾没有明显吸引作用;河源油栗的果实和叶片挥发物则对雌、雄蛾均无吸引作用.触角电位反应试验表明,桃蛀螟雌蛾对农大1号板栗果实挥发物的反应比河源油栗果实强烈,但雄蛾没有明显差异;同一品种中,雌、雄蛾对果实的反应均比叶片强烈.桃蛀螟雌蛾在农大1号板栗果实上的产卵量明显高于叶片及河源油栗的果实和叶片,而后三者之间差异不显著. The effects of chestnut volatiles on the host-selection behavior of adult adults of Conogethes punctiferalis were studied by field investigation, behavioral response, EAG response and oviposition preference.The field survey results from 2004-2008 showed that: Nongda 1 chestnut fruit borer rate of 16.1% ~ 25.3%, while in Heyuan oil chestnut fruit rate were less than 5%, the borer borer harm to the former significantly heavier.Nongda No. 1 chestnut fruit and leaves Volatiles on the moth bore moth female have significant role in attracting, of which the fruit is more attractive than leaf volatiles, but the volatiles on the male moth did not significantly attract the role of Heyuan oil and leaf volatiles of the female , Male were non-attracting role.The tentacles potential response test showed that the female moth borer on the Nongda 1 chestnut fruit volatiles than the Heyuan oil chestnut strong, but the male moth no significant difference; the same species, male and female The response of moths to the fruit was stronger than that of the leaves.The fecundity of the female moth borer was significantly higher than that of the leaves and the hen oil, but the difference was insignificant.
