Beschreibung
Zusammenfassung:	The invention relates to the field of insect prevention and control, in particular to a paecilomyces lilacinus strain XI-5 and crude toxin extracted and identified from the paecilomyces lilacinus strain XI-5 and generated by secondary metabolites of the paecilomyces lilacinus strain XI-5. The invention proves that the secondary metabolite of the paecilomyces lilacinus strain XI-5 generates cyclosporin C. The cyclosporin C has a stomach toxicity effect on bemisia tabaci adults. After the cyclosporin C is applied for 24 hours, the LC50 concentration of the cyclosporin C on bemisia tabaci adults is 31.75 g/ml; compared with a control group, the LC30 concentration of cyclosporin C leads to reduction of female egg laying amount/reproductive power of bemisia tabaci. 本发明涉及昆虫防治领域，具体涉及淡紫拟青霉菌株XI-5，以及从中提取和鉴定淡紫拟青霉菌株XI-5次生代谢物产生的粗毒素。本发明证实了淡紫拟青霉菌株XI-5次生代谢物产生环孢菌素C。环孢菌素C对烟粉虱成虫具有胃毒作用。应用24小时后，环孢菌素C对烟粉虱成虫的LC50浓度为31.75µg/ml；与对照组相比，环孢菌素C的LC30浓度导致烟粉虱雌性产卵量/生殖力降低。
