【摘要】 利用玻片记数法测定了改装的高压(3万V)静电喷粉机的喷粉效果,并利用此机在林间喷施苏特灵(Bt混合生物制剂)粉剂对3～4龄马尾松毛虫进行了防治试验。结果表明,静电喷粉效果平均为常规喷粉的3.2倍,静电喷粉杀虫效果平均为常规喷粉的2.5倍。更多还原

【Abstract】 The dusting effect of the refited high voltage (30,000v) electrostatic duster was determined using the sheet glass counting methode, and the control experiment dusting Suteling powder (a Bt insecticide) against Den-drolimus punctatus was carried out in masson-pine culture by use of the high voltage electrostatic duster. The results showed that the effect of electrostatic dusting was average 3 times as the routine dusting, and the mortality of D.punctatus larvae (3 ~ 4instar) by using electrostatic dusting technique was over 2.5 times as by using routine dusting technique.更多还原
