5种杀虫剂对橡副珠蜡蚧的田间防效

Control Effects of Five Insecticides on the Sapphire in Field

橡副珠蜡蚧是橡胶树重要害虫。为了推荐生产上有效药剂,在室外开展了 5 种杀虫剂[爱本(氟啶·毒死蜱)、螺虫乙酯、噻嗪酮、氟啶虫酰、毒死蜱]对橡副珠蜡蚧的防治试验。结果表明:施药 15 d 后,爱本悬浮剂防治效果最好,其 1500 倍液和 2500 倍液的防效分别为 100%、99.21%;其次为毒死蜱乳油 800 倍液,防效为 98.5%;噻嗪酮悬浮剂的防效一般,其 1000 倍液和 2000 倍液的防效分别为 79.29%、70.72%;螺虫乙酯 3000 倍液、氟啶虫酰胺 3000 倍防效最差,分别 38.62%、30.07%。根据防效测定结果,推荐生产上可选用爱本悬浮剂 1500~2500 倍、毒死蜱 800 倍作为橡副珠蜡蚧防治药剂。

Parasaissetia nigra Nietner is a main pest of rubber trees.In order to find the effective pesticides to it,five kinds of insecticides[Ai Ben(fluridine,chlorpyrifos),spirotetramat,buprofezin,flonica,chlorpyrifos]were applied to the test the control effects the Parasaissetia nigra Nietner.The results showed that after 15 days of application,Aiben suspension was the best,and the control effects of 1500 times and 2500 times liquid were 100%and 99.21%,respectively.It was followed by chlorpyrifos cream 800 times,and the control effect was 98.5%.The buprofezin suspension had general control effect,the control effect of 1000 times liquid and 2000 times liquid were 79.29%and 70.72%,respectively.The spirotetraethyl ester 3000 times liquid and flonica amide 3000 times had the worst control effect,respectively which were 38.62%,30.07%.According to the results,it is recommended to use 1500-2500 times of the Aiben suspension or 800 times of the chlorpyrifos as the control agent with applicabe concentration of the Parasaissetia nigra Nietner.
