摘要:
以中国梨木虱Psylla chinensis为试虫，采用田间药效试验方法，研究了3种新型杀虫剂对中国梨木虱的田间防效，以期确定防治梨木虱的理想药剂及最佳时期。结果表明：在2次试验中螺虫乙酯悬浮剂对梨木虱药后7~21 d防效均达90%以上，是防控梨木虱首选药剂；其它药剂防效较差，其中氟啶虫胺腈与乙基多杀菌素混用防效优于单剂；在卵孵化末期施药的防效优于若虫期。建议在梨木虱一代卵孵化末期选用240 g?L-1螺虫乙酯悬浮剂3 000倍液进行防治，注意与其它药剂轮换使用，避免梨木虱对该药剂产生抗药性。
Abstract:
In order to determine the efficient pesticides and suitable period to control the pear psylla Psylla chinensis (Hemiptera：Psyllidae),the filed control efficacy of three new insecticides on pear psylla were studied.The results showed that the spirotetramat performed the best against the pear psylla with control efficiency above 90% after 7—21 days of application in the two treatments.The other two pesticides showed little efficiency.However,the mixture of sulfoxaflor and spinetoram showed higher control efficiency than single dose.Application of insecticide at the end of egg hatching stage of the first generation showed higher control efficacy at the nymphal stage.It was recommend that spraying at the period of the end of egg hatching stage of first generation using 3 000 times dilution of spirotetramat 240 g?L-1 SC for the control of pear psylla.Alternative insecticides should be used for rotation to avoid the development of resistance of pear psylla in field.
