春尺蠖羽化期监测及其无公害防治试验

目的]通过对新疆阿克苏市春尺蠖羽化期的动态监测,旨在掌握春尺蠖的最佳防治时期;春尺蠖的无公害防治试验,为春尺蠖高效无公害防治技术在阿克苏地区的推广应用提供参考.方法]成虫期利用光控杀虫灯、糖醋液、树干涂胶来进行动态监测;成虫期采取树干直接涂胶、间接涂胶来进行防治;幼虫期采取两种生物制剂来进行防治.结果]阿克苏市春尺蠖的羽化期在3月5～27日.雄虫的羽化期比雌虫的羽化期要早3～5 d.无公害防治试验结果表明:树干直接涂胶比间接涂胶的捕获数量高出6.8倍;从幼虫虫口密度减退率来看,树干间接涂胶后的幼虫虫口密度比树干直接涂胶后的幼虫虫口密度高出2.2倍;两种生物制剂以核型多角体病毒的效果最好,其防治效果达到90.74;.结论]春尺蠖的最佳防治时期应在3月5日之前,利用雌、雄虫不同的羽化期分而治之.羽化期的监测使用控杀虫灯的效果较好,发生量监测使用树干涂胶效果较好.无公害防治试验中树干直接涂胶和核型多角体病毒的效果好,且对果树、果品安全.

Eclosion Monitoring and Non-pollution Control Trial of Apocheima Cinerarius Erschoff

【Objective】To ascertain the best control periods against Apocheima cinerarius Erschoff through dynamic monitoring of its eclosion period in Akesu,Xinjiang.By conducting non-pollution control trials against Apocheima cinerarius Erschoff,reference will be provided for popularization and application of high efficacy non-pollution techniques to control Apocheima cinerarius Erschoff in Akesu area.【Method】Light control insecticidal lamps,sweet and sour fluid,and glue spraying on the trunk are used for dynamic monitoring of Apocheima cinerarius Erschoff during adulthood.Direct spraying glues on the trunk and indirect spraying on the adhesive tape are used to control Apocheima cinerarius Erschoff during adulthood stage.Two biological agents are used to control Apocheima cinerarius Erschoff larvae.【Result】The results of dynamic monitoring showed that eclosion periods were between March 5-March 27 in Akesu.The male eclosion period was 3 or 5 d earlier than female eclosion period.The results of non-pollution control trial showed that the trunk with direct glue spraying treatment has a captured pest number 6.8 times higher than the indirect adhesive glue spraying treatment.In the view of the mortality of larval population density,the larval population density of the trunks treated with direct glue spraying is 2.2 times higher than that of treated with indirect adhesive glus spraying.As for the two biological agents,AciNPV has a better control effect,its control efficacy can reach 90.74%.【Conclusion】The best periods for controlling Apocheima cinerarius Erschoff is before March 5,and they can be controlled differently based on different male and female eclosion period.In the monitoring process during eclosion period,the light control insecticidal lamps have a good control efficiency,while by utilizing glue spraying on the trunk to monitor its occurrence have a good effect.Spraying directly on the trunk and AciNPV have the best control efficacy in the non-pollution control trial.They are safe both for the fruit trees and fruit.
