植物次生代谢物丁布对苜蓿斑蚜的控制作用
Effects of Plant Secondary Metabolite DIMBOA on Therioaphis trifolii Monel(Homptera:Aphididae)
摘要
Abstract
The effects of plant secondary metabolite DIMBOA on the growth,development and reproduction of Therioaphis trifolii Monel were investigated by mixingdifferent concentrations of DIMBOA with artificial diet.The results showed that the survival rate,reproductive rate and protease activity of T.trifolii were significantly reduced by high concentration of DIMBOA.When the T.trifolii adults were fed 800 μg/mL DIMBOA for 72 h,compared with the control group,the survival rate was reduced by 53.06%and the reproductive rate,by 53.82%.The survival rate of the T.trifolii larva was only 35.8%,significantly lower than that of the control group.The activities of aminopeptidases(APs),chymotrypsin(CTP),trypsin(Tr),and total protease(Pr)in T.trifolii adults were significantly inhibited by different concentrations of DIMBOA,especially by high concentration of DIMBOA.The activities of Aps,CTP,Tr and Pr were reduced by 61.5%,67%,65.1%and 55.9%,respectively,in the insects fed with 800 μg/mL DIMBOA for 72 h.These results indicate that DIMBOA can significantly reduce the survival rate and reproductive rate of T.trifolii,showing a potential for the development of plant-derived pesticides.关键词
