3种无公害技术防治落叶松叶蜂研究

Control of Pristiphora erichsonii with Three Kinds of Pollution Free Agents

为探索落叶松叶蜂无公害防治技术,2017年在六盘山林区开展了利用粘虫板、烟碱·苦参碱、六盘山翠金小蜂防治落叶松叶蜂试验。结果表明,在绿色、黄绿色、土黄色、红色4种颜色粘虫板中,落叶松叶蜂成虫最趋向于绿色;不同浓度的烟碱·苦参碱对幼虫都有一定的防治效果,其中稀释10倍液防治效果为92.39%,最经济有效;不同放蜂量的六盘山翠金小蜂,按虫蜂比为1∶5放蜂最经济有效。筛选出的3种无公害技术对落叶松叶蜂防治效果均高于90%,具有较高的推广价值。

In order to explore the non-pollution prevention technology of Pristiphora erichsonii in 2017, the experiment of controlling using the armyworm board, nicotine-matrine, and Tritneptis liupanshanensis was performed in the forest area of Liupan Mountain. The results showed that in four colors of the sticky plate which are green, yellow-green, yellow, and red colors, the adults of Pristiphora erichsonii have the highest propensity in green; Different concentrations of nicotine and matrine have certain control effects on larvae, and the control effect of diluting 10 times liquid is 92.39%, which is the most economical and effective; The ratio of Pristiphora erichsonii to Tritneptis liupanshanensis is most effective when it is 1：5. The three non-pollution technologies screened out have higher control efficacy than the other 90%, and have high promotion value.
