摘要
采用叶碟浸液法,研究松香基三环二萜类脱氢枞基酰胺及亚胺衍生物对粘虫(Mythimna separata)的拒食活性。结果显示,含有脱氢枞基结构的酰胺衍生物脱氢枞基酰胺(A-1)、脱氢枞基酰苄胺(A-3)、脱氢枞基酰邻氟苯胺(A-4)、脱氢枞基酰三氟甲基苯胺(A-8)、脱氢枞基吗啉(A-10)及含有亚胺结构的衍生物脱氢枞胺对三氟甲基苯甲醛(I-6)对粘虫的拒食活性较高,24 h的拒食率均达到90%以上。A-1、A-4、A-8、A-10及I-6在48、72 h的拒食率也达到80%以上。大部分酰胺化合物表现出拒食活性,部分亚胺衍生物施药时间长的情况下表现出一定的诱食活性。部分化合物在拒食活性测试过程中发现幼虫死亡现象,可以作为杀虫剂继续开发。
In this study,the antifeedant activities of rosin-based tricycle diterpenoids dehydroabietyl amides and imines derivatives against Mythimna separata were investigated by leaf-disc immersion method. The results showed that amide derivatives,A-1,A-3,A-4,A-8,A-10,and imine derivatives I-6 containing dehydroabietyl structure had good antifeedant activities to Mythimna separata and their antifeedant rates were all over 90% in 24 h. The antifeedant rates of A-1,A-4,A-8,A-10,and I-6 were over 80% in48 h and 72 h. The majority of amide compounds showed antifeedant activities and some imine derivatives showed feeding attracion activities after long time. Some compounds could cause the death of armyworms during antifeedant activity test,so these compounds could be developed as insecticides.
