Study on biological habits and control of Scirothrips dorsalis hood on mangoes | 芒果茶黄蓟马生物学特性及其防治研究

Chinese. [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。

English. [Objective] This study aimed to explore the biological habits of Scirothrips dorsalis Hood and methods for controlling this pest. [Method] From 2009 to 2011, the biological habits of Scirothrips dorsalis Hood and the regularity of its occurrence on mangoes were investigated at the experimental base of the Institute of Tropical and Subtropical Cash Crops, Yunnan Academy of Agricultural Sciences and Shuanghongqiao Mango Orchard in Baoshan, Yunnan Province. In addition, a field trial on the effects of four medicaments on controlling this pest was also conducted. [Result] The result showed that Scirothrips dorsalis Hood completed 10-12 generations per year in Baoshan area, and the peak period of its incidence was from February to April. The results of the pest control testing showed that at 0.05 level, there were significant differences of effect on pest controlling among the treatments I, II and IV, and the treatment III showed significant differences of controlling effect with the treatment IV, while no significant differences with either the treatment I or the treatment II; at 0.01 level, there was no significant difference among the treatments I, II and III, while all the three treatments showed significant differences with treatment IV. [Conclusion] This study revealed that the occurrence and the severity of Scirothrips dorsalis Hood on mangoes in Baoshan, Yunnan Province. In addition, pesticides with certain efficacy on controlling Scirothrips dorsalis Hood were screened, which provides more options for fruit growers to control this pest on mangoes.
