【摘要】 生测结果表明,温度对杀虫植物苦皮藤麻醉成分的毒力有显著影响,在试验温度范围内,毒力随温度升高而降低,即苦皮藤是具有负温度系数的杀虫剂。温度升高,昆虫体内酯酶活性增加,解毒作用加强,这可能是产生负温度系数的主要原因。更多还原

【Abstract】 The results of the bioassay showed that temperature affected the toxicity of the narcotic component of Celastrus angulatus significantly. Within tested temperatures, the toxicity became lower as the tested temperature was higher, i. e. Celastrus angulatus was a botanical insecticide with negative temperature factor. With higher temperature, the activity of esterase in the insect bodies was increased, while the detoxication was enhanced as a result of increasing esterase activity. This may be a main reason for negative temperature factor.更多还原
