Abstract
Effects of an insecticidal soap on the survival, development and reproduction of the green peach aphid, Myzus persicae, were studied. Twenty-four hours after application at a concentration of 37.50 g L-1, the soap caused 100% mortality in all aphid instars, and LC50 (lethal concentrations causing 50% mortality in the population) were 1.50, 3.25 and 5.50 g L-1 for first and second instars, third and fourth instars, and adult M. persicae, respectively. Aphids that survived the LC50 had a shorter longevity than the controls. Both insecticidal soap and parasitoids could be used on a crop but, as the LC50 of the third and fourth instars and adult M. persicae are higher than that of the aphid parasitoid Aphidius colemani (2.75 g L-1), it is essential to avoid treating aphids with insecticidal soap when adult parasitoids are present in the crop.
研究了一种杀虫皂对桃蚜(Myzus persicae)存活、发育和繁殖的影响。施用后24 h，皂液浓度为37.50 g L-1，对1、2龄、3、4龄和成虫的LC50分别为1.50、3.25和5.50 g L-1，对所有蚜虫的死亡率均为100%。在LC50环境下存活下来的蚜虫寿命比对照组短。杀虫皂和拟寄生蜂均可用于作物，但由于桃蚜3、4龄和成虫的LC50高于拟寄生蜂蚜的LC50 (2.75 g L-1)，因此当作物中存在成虫时，应避免使用杀虫皂处理蚜虫。
