5种杀虫剂对苹果绵蚜的田间防效和安全性综合评价

摘要

In this paper,the field effect and safety of five kinds of insecticides were analyzed and evaluated comprehensively through the control effect,rapid availability,persistence,mortality (prediction),detection rate,acute risk and chronic risk by using membership function and factor analysis.The results showed that the seven comprehensive evaluation indexes of field control efficacy and safety could be transformed into three main components of safety factor,control factor and rapid availability factor.The comprehensive evaluation values were as follows:2％ abamectin EC＞ 20％ imidacloprid EC ＞ 10％ cypermethrin EC ＞ 40％ chlorpyrifos EC ＞ 5％ acetamiprid WP.2％ abamectin EC is the best pesticide for controlling apple aphid because of its high safety and good control effect.%本文应用主成分分析法,通过防治效果、速效性、持久性、预测死亡率、检出率、急性膳食摄入风险和慢性膳食摄入风险7个指标,从田间防效和安全性两方面对5种杀虫荆的田间应用效果进行了分析和综合评价.结果表明:7个田间防效和安全性综合评价指标可转化为安全性因子、防效因子和速效性因子3个主成分.综合评价值从高到低依次为:2％阿维菌素乳油＞20％吡虫啉乳油＞10％氯氰菊酯乳油＞40％毒死蜱乳油＞5％啶虫脒可湿性粉剂;2％阿维菌素乳油安全性高、防效好,是防控苹果绵蚜的理想药剂.
