不同防控措施对黄曲条跳甲的应用效果

Application Effect of Different Control Measures on Phyllotreta striolata(Fabricius)

为了解不同防控措施对黄曲条跳甲的应用效果,促进土壤处理和防虫网的推广应用,通过田间试验,以常规施药为对照,比较防虫网和土壤处理联合防虫网处理对黄曲条跳甲的防治效果,以及其使用成本和对作物产量的影响。结果表明,土壤处理联合防虫网对黄曲条跳甲的阻隔作用最高,达86.5%,防虫网对黄曲条跳甲的阻隔作用为77.2%。土壤处理联合防虫网和防虫网处理区单株质量和产量均比常规防治区高,农药使用次数减少2~3次,农药使用量减少38%~58%。综合考虑防治效果、物资成本和增产效果等因素,生产中推荐全生育期使用小拱棚防虫网防治黄曲条跳甲,经济允许条件下可利用生物制剂进行土壤处理,具有一定增效效果。

In order to study and understand the application effects of different control measures on Phyllotreta striolata(Fabricius),promote the promotion and application of soil treatment and insect prevention nets,field experiments were conducted to compare the control effects of insect prevention nets and soil treatment combined with insect prevention nets on Phyllotreta striolata(Fabricius),as well as their use costs and effect on crop yield.The results showed that the soil treatment combined with insect prevention net area had the highest barrier effect,reaching 86.5%,and the barrier effect of the insect prevention net area on Phyllotreta striolata(Fabricius)was 77.2%.The quality and yield of individual plants in the soil treatment combined with insect prevention nets and insect prevention nets treatment area were higher than those in the conventional control area,with a decrease of 2-3 times in pesticide use and a decrease of 38%-58%in pesticide use.Taking into ac⁃count factors such as prevention and control effects,material costs,and yield increase,it was recommended to use small arched shed insect prevention nets throughout the entire growth period to prevent and control Phyllotreta striolata(Fabricius).Under economic conditions,biolog⁃ical agents could be used for soil treatment,which had a certain synergistic effect.
