摘要
中山温泉高尔夫球场自八十年代中期建成使用以来,球场草地就受到害虫的为害。主要害虫为水稻叶夜蛾(也称眉纹夜蛾)Spodoptera mauritia 和水稻切叶野螟 Herpetogra-mma licarsisalis.开始时用辛硫磷防治,效果很好,经多年连续使用,效果越来越差.1990年7月,笔者在室内用98%巴丹原粉2000倍、50%巴丹可溶性粉500倍、25%杀虫双200倍和虫敌Ⅰ号1000倍,对水稻叶夜蛾杀虫率达到92.89～100%.98%巴丹原粉对水稻切叶野螟毒力测定,24小时后检查杀虫效果,y=13.7162+5.3381x,r=0.9611(相关非常显著)LC_(50)为4293.67倍,LC_(90)为2471.97倍.
The Zhong Shan Hot spring Golf Club was established in 1980's.since
then the growth of gras of this Club has been suppressed by pests.The important
pests were Spodoptera mauritia and Herpetogramma.licarsislis.Using phoxim for
control of the two pests gave better offect at early stage,but after many years,
the controlling efficiency became lass and lass.A series of experiments on the
effectiveness against these pests was carried out in 1990.Results of laboratory
experiments showed that the spraying of 2000 times of 98% C.P.padan,500 times
of 50% S.P.padan,200 times of 25% dimehypo and 1000 times of“Chongdi-1”to
the larvae of S.mauritia gave the mortality of 92.89～100%.The LC_(50) and LC_(90)
of spraying 98% C.P.padan to the larvae of H.licarsislis were 4293.67 times and
2471.97 times after 24 hours respectivily(y=13.7162+5.3381x,r=0.9611).
