摘要

随着以天敌为生物防治手段的综合防治体系的推广,茄粉蚧(Phenacoccus solani Ferris)已成为我国严重的害虫。我们在实验室和茄子田测试了现有杀虫剂的功效。实验室实验在25°C, 14L:10D的受控环境下进行,材料为绿豆小叶。为了区分不同的发育阶段,研究人员每天对茄茄的体长和发育时间进行研究。我们不能通过体长来区分粉蚧的不同发育阶段;然而,我们可以从出生的天数(日龄)来估计发育阶段。以日龄计算,1龄若虫发育期小于4天,2龄若虫发育期为8 ~ 9天,3龄若虫发育期为14 ~ 16天,雌成虫发育期大于25天。用14种杀虫剂对2、3龄若虫和雌成虫进行了试验。三种化学杀虫剂(啶虫脒、硝啶虫胺和亚砜)和两种阻断螺旋的杀虫剂(癸烷辛烷酰甘油和氢化淀粉水解物(HSH))特别有效。还在温室中评价了选定的杀虫剂(啶虫脒、亚砜和HSH)的药效。结果表明,磺胺呋虫胺是最有效的,其次是啶虫脒,第三是HSH。

Effectiveness of Available Insecticides against the Solanum Mealybug, Phenacoccus solani(Hemiptera: Pseudococcidae)
The solanum mealybug, Phenacoccus solani Ferris(Hemiptera: Pseudococcidae), has become a serious pest with the extension of the IPM system based on biological control using natural enemies. We tested the efficacy of available insecticides in the laboratory and eggplant fields. Laboratory experiments were performed under a controlled environment of 25°C and 14L:10D using green bean leaflets. To distinguish each developmental stage of P. solani, the body length and developmental time were investigated every day. We were unable to distinguish the different developmental stages of the mealybugs by body length; however, we could estimate the developmental stage from the number of days from birth(day-age). The estimated developmental stages in terms of day-age were below 4 days for 1st instar nymphs, 8–9 days for 2nd instar nymphs, 14–16 days for 3rd instar nymphs, and over 25 days for female adults. Fourteen insecticides were tested against 2nd and 3rd instar nymphs and female adults. Three chemical insecticides (acetamiprid, nitenpyram, and sulfoxaflor)and two spiracle-blocking insecticides(decanoyloctanoylglycerol and hydrogenated starch hydrolysate(HSH))were particularly effective. The efficacy of selected insecticides (acetamiprid, sulfoxaflor, and HSH)was also evaluated in a greenhouse. The results showed that sulfoxaflor was the most effective, with acetamiprid in second place, and HSH in third.
