摘要
为考察无公害技术对落叶松叶蜂的防治效果,文章分别考察了不同颜色粘虫板、不同浓度烟碱·苦参碱、不同虫蜂比对落叶松叶蜂的防治效果。结果显示:颜色不同的粘虫板对落叶松叶蜂表现出不同的防治效果,趋色性为红色<土黄色<黄色<绿色,其中绿色粘虫板的防治效果为94.51%,显著高于其他3种颜色的粘虫板处理;采用烟碱·苦参碱乳油进行防治,稀释5倍后的校正防治效果最高为95.29%,但与10倍液防治效果(92.95%)无显著差异,喷施10倍液最为经济有效;释放六盘山翠金小蜂防治效果显示,虫蜂比为1∶6时,校正防治效果达到了92.73%,高于90%,显著高于其他虫蜂比处理。
In order to investigate the control effect of pollution-free technology on Pristiphora erichsonii Hartig,this paper investigated the control effect of different colors of armyworm plates,different concentrations of nicotinic acid matrine and different insect bee ratios.The results showed that different colors of armyworm plates showed different control effects on Pristiphora erichsonii Hartig,and the color trend was red<earthy yellow<yellow<green.The control effect of green armyworm plates was 94.51%,which was significantly higher than that of the other three colors of armyworm plates.The control effect of nicotine-matrine emulsion was 95.29%after 5 times dilution,but there was no significant difference with the control effect of 10 times liquid(92.95%).Spraying 10 times liquid was the most economical and effective.When the ratio of insect to bee was 1∶6,the corrected control effect reached 92.73%,higher than 90%,which was significantly higher than that of other treatments.The three tested prevention and control technologies are all pollution-free,and can achieve more than 90%of the control effect,and the promotion value is high.
