摘要
用金龟子绿僵菌(Metarhiziumanisopliae)3305-6、球孢白僵菌(Beauveriabassiana)9139布氏白僵菌(Beauveriabrongniartii)7201的分生孢子混以天然活性剂后与试管鲜土拌匀引入两星牧场金龟的室内生测,用球孢白僵菌9139菌剂混以天然活性剂防治玉米暝的小区试验结果表明,在玉米喇叭口期加有KL-天然活性剂的比对照有明显缩短害虫病程、提高真菌病原毒力的效果。
Aphadius elegans and Ostrinia nubilalis were. controlled using conidia of B. basiana 9139, B. brongniartii 7201 and M. anisoplies 3305-6 with natural active compound KL in laboratory and field. Experiment results showed that the conidia with KL was able to shorten the course of disease and increase a pathogenic percentage. Especially, the effect of a strain 7201 was very distinct.
