[目的]评估氯虫苯甲酰胺对螟黄赤眼蜂和玉米螟赤眼蜂的安全性。[方法]室内测定该药剂对2种赤眼蜂的急性毒力、发育、存活和寄生能力的影响,以高效氯氰菊酯和阿维菌素作为对照药剂。[结果]阿维菌素毒力最高,安全系数最低(0.007~0.011),而氯虫苯甲酰胺毒力最小,安全系数最高(1.594×103~3.054×103);氯虫苯甲酰胺处理赤眼蜂的羽化率最大(88.19%~89.32%),阿维菌素处理的羽化率最低(8.87%~16.73%);接触各残留期氯虫苯甲酰胺,2种赤眼蜂的死亡率最低(3.33%~13.33%),寄生米蛾卵数量最多(27.1~39.7粒)。[结论]在实施释放赤眼蜂的IPM方案中,阿维菌素尽量避免使用,而氯虫苯甲酰胺值得推广使用。
[Objective] To evaluate the safety of chlorantraniliprole against Trichogramma ostriniae and Trichogramma ostriniae. [Method] The effects of the agent on the acute toxicity, development, survival and parasitism of two Trichogramma species were determined indoors. Beta-cypermethrin and abamectin were used as control agents. [Result] The avermectin had the highest virulence with the lowest safety factor (0.007 ~ 0.011), while the lowest virulence of chlorantraniliprole with the highest safety factor (1.594 × 103 ~ 3.054 × 103) The emergence rate of eye bee was the highest (88.19% -89.32%), and the lowest was the rate of emergence of avermectin (8.87% -16.73%). The lowest mortality was observed when exposed to each of the residual chlorantranifolin (3.33% ~ 13.33%), the largest number of parasitoid moth eggs (27.1 ~ 39.7). [Conclusion] Abamectin should be avoided as far as possible in the IPM program of Trichogramma decumbens. However, it is worth to promote the use of.
