摘要
为了有效提升对云杉芽小卷蛾幼虫的防治效果,通过室内和田间药效试验对比了3种药剂不同浓度梯度下的防效水平,为有效控制虫害,减少经济损失提供可行性方案。结果表明:0.05%~0.067%的阿维菌素乳油防效最高,在室内及田间应用效果最佳。实际生产中可在每年的7月份,根据当地情况,联合使用阿维菌素乳油与高渗苯氧威乳油,可有效提高对云杉芽小卷蛾幼虫的防治效果。
In order to effectively improve the control effect on larva of spruce bud,the effective levels of three kinds of agents under different concentration gradient were compared through indoor and field efficacy tests,which provided a feasible plan for effectively controlling insect pests and reducing economic losses. The results showed that 5 % to 0.067 % of the abamectin Emulsifiable oil had the highest preventive effect and was the best in indoor and field applications. In actual production,it can be used in July each year. According to local conditions,the combined use of abamectin Emulsifiable oil and percolated benzoyl Emulsifiable oil can effectively improve the prevention and treatment of spruce Bud moth larvae.
