Abstract

The insecticidal efficacy of aqueous extracts of R. communis L. and Z. officinales L. was tested in a field study for the control of two important leaf defoliators (Podagrica uniformis and Nisotra sjostedti of okra). The extracts were applied at 10% (w/v) and sprayed every week for five consecutive weeks. R. communis significantly reduced (P<0.05) abundance of the pests on the 2nd day after spraying and increased the yield of okra. Numbers of fruits and weight yields were significantly higher in plots treated with R. communis compared to plots treated with Z. officinales and the untreated control. R. communis had the same weight yield with Karate (synthetic insecticides). The results indicated that R. communis could be used to control Podagrica uniformis and Nisotra sjostedti of okra.

植物性杀虫剂对秋葵叶片脱叶虫(均匀足跖虫和黄足跖虫)的防治效果研究

以秋葵为研究对象，对两种重要的落叶害虫——均匀足跖虫(Podagrica uniformis)和秋葵尼索特拉(Nisotra sjostedti)的防治效果进行了田间试验。提取液以10% (w/v)的浓度施用，每周喷洒，连续5周。在喷施后第2天，褐飞蛾显著降低了害虫的丰度(P<0.05)，提高了秋葵的产量。与未处理的对照和铁皮草处理相比，处理过的田块的果实数量和单产显著增加。与合成杀虫剂“空手道”(Karate)产量相当。结果表明，黄芪可用于防治秋葵的长角天牛和小角天牛。
