[目的]研究茶黄蓟马生物学特性及其防治方法。[方法]在2009～2011年间,以云南省保山市隆阳区路江镇省农科院热经所试验基地和保山市隆阳区潞江镇双虹桥芒果园为试验地点,开展芒果茶黄蓟马生物学特性及发病规律研究,并选择4种药剂在田间进行药效试验。[结果]芒果茶黄蓟马在保山每年发生10～12代,2～4月是发生高峰期。药效试验结果显示,处理1、处理2、处理4在5%显著水平下差异显著;在5%显著水平下,处理3与处理4之间差异显著,与处理1、2之间差异不显著;在1%极显著水平下,处理1、2、3之间差异均不显著,但处理4与处理1、2、3之间均存在极显著差异。[结论]该研究明确了芒果茶黄蓟马在云南保山的发生规律及危害情况,同时筛选出对芒果茶黄蓟马有一定防治效果的杀虫剂,为果农开展芒果茶黄蓟马的防治提供了更多的选择。
[Objective] The research aimed to study the biological characteristics of Thrips palmi and its control methods. [Method] From 2009 to 2011, taking the thermal experiment base of Lujiang Town Provincial Academy of Agricultural Sciences in Longyang District, Baoshan City, Yunnan Province and Mangrove Orchard of Shuangghong Bridge in Lujiang Town, Longyang District, Baoshan City as test sites, Thrips biological characteristics and pathogenesis study, and select four kinds of agents in the field efficacy test. [Result] The mangrove tea thrips occurred in Baoshan from 10 to 12 generations per year, and peaked from February to April. The results of the efficacy test showed that treatments 1, 2 and 4 showed significant differences at the 5% significant level; at the 5% significant level, there was a significant difference between treatments 3 and 4, and there was no significant difference between treatments 1 and 2 ; At the extremely significant level of 1%, the differences between treatments 1, 2 and 3 were not significant, but there was a significant difference between treatments 4 and 1,2,3. [Conclusion] The study identified the occurrence and damage of Phylloxia trigianis in Baoshan, Yunnan. At the same time, it also screened the insecticides that had certain control effect on Thrips palmi, preventing and controlling mango. Provide more choices.
