在松墨天牛等蛀干害虫活动期,在云南松-杉木、柏树针叶混交林,云南松-栎类、木荷针阔混交林2种不同的林分中,选用广东林科院研制的A-3型松褐天牛引诱剂和与之配套的YB-50诱捕器,在混交林中首次进行了鞘翅类害虫诱捕试验。试验结果显示,A-3型引诱剂诱获鞘翅类昆虫747头,隶属于8个科11种,一种天敌昆虫,并对主要蛀干害虫活动期进行统计分析。A-3型引诱剂诱捕是监测混交林钻蛀性害虫种群动态和降低虫口密度的重要方法。
In Monochamus alternatus and other pests, two kinds of stands were selected from two different stands of Pinus yunnanensis-Cunninghamia lanceolata and Cypress coniferous forest, Pinus yunnanensis-Quercus acutissima and Schima superba mixed forest, A-3 Monochamus alternatus and their associated YB-50 traps, the coleopteran pest trap test was first conducted in the mixed forest. The results showed that 747 coleopteran insects were induced by type A-3 attractants, which belonged to 11 species of 8 families and one natural enemy insect. Statistical analyzes were carried out on the active periods of major stem borers. Trapping A-3 attractant is an important method to monitor the dynamics of population of borer pests in mixed forest and to reduce population density.
