从欧洲玉米螟Ostrinia nubilalis幼虫虫粪中提取雌蛾产卵的忌避物,1983年Dittrick已有报导。我们发现亚洲玉米螟Ostrinia funacalis的幼虫虫粪中也存在雌蛾产卵的忌避物。 60年代初叶,作者在田间观察到有幼虫虫粪的玉米植株上,第一代雌蛾就很少去产卵。1964年辐射不育的玉米螟纱笼释放试验时,也出现田间观察到的类似现象。玉米螟雌蛾产卵场所的这种选择性,说明它们在长期生命活动中,对某种生化物质形成了条件反应,此生化物质引起“行为”隔离,调节产卵趋避的运动方向,引起作者注意。
Dirtshields have been reported in 1983 to extract female egg-laying bogey from the European corn borer Ostrinia nubilalis larvae. We found that the female moth oviposit also existed in the larvae of the Asian corn borer Ostrinia funacalis. In the early 1960s, the first generation of female moths rarely spawned on the corn plants observed to have larvae in the field. A similar phenomenon observed in the field also occurred during the test of releasing silage from maize in 1964. This selectivity of the oviposition site of the female corn borer suggests that they exert a conditioned response to certain biochemical substances during long-term life events that cause “behavioral” isolation and regulate the direction in which the eggs lay away, note.
