为有效防止茶园的黑刺粉虱,提高茶园的种植效益,采用信息素诱虫板对黑刺粉虱进行诱捕试验,试验结果表明防治效果明显,诱捕区黑刺粉虱虫口减退率达到79.0%,能有效防治黑刺粉虱对茶园的危害。由此表明,信息素诱虫板防治茶园黑刺粉虱可大力推广应用。黑刺粉虱为广布性昆虫,是目前全国大部分茶区常见的主要茶树害虫。从多年研究报道资料可见,茶园出现大发生的概率较高,田间虫口密度大,危害严重,对茶叶产量品质影响较大。
In order to effectively prevent black spot whitefly in tea plantation and improve the planting benefit of tea plantation, trapping experiments on blackfly whitefly were carried out with pheromone-induced board, the results showed that the control effect was obvious, and the reduction rate of blackfly whitefly was 79.0% , Can effectively prevent the blackfly whitefly on the hazards of the tea plantation. This shows that the pheromone trap board Tenebrio Tenebrion Prevention and Control can be vigorously promote the use of. Black twig whitefly is a widely distributed insects, is currently the main tea tree pests in most tea areas. From years of research reports, we can see that there is a high probability of large occurrence of tea plantations, large density of insect pests in the field and serious harm to tea yield and quality.
