Acrolepiopsis assectella andPlutella xylostella frass volatiles, trapped on Tenax GC, were examined by capillary gas chromatography. In both moths, the same three disulfides, dimethyl, dipropyl, and methyl propyl, were the most abundant substances, but in different proportions. The synthetic disulfides elicited the same behavioral response by the parasitoid,Diadromus pulchellus as frass. The plant origin of these substances is discussed.
小菜蛾和黄曲条跳甲幼虫粪便挥发物用 Tenax GC 捕获后,用毛细管气相色谱法进行了检测。在这两种鳞翅目昆虫中,同样的三种二硫化合物,二甲基、二丙基和甲基丙基,是最丰富的物质,但比例不同。合成的二硫化合物与黄曲条跳甲幼虫粪便一样,引起了寄生蜂草蛉的相同行为反应。这些物质的植物来源正在讨论中。
