| 中文摘要: |
| 通过3年调查研究,初步明确在浙江温州夏秋季节斜纹夜蛾喜产卵于毛芋上,毛芋上平均卵块量为0.162块／m2,青菜上为0.04块/m2,是青菜上的4.0倍;青菜套种毛芋与青菜田(CK)相比青菜上平均落卵量和幼虫量分别减少39.13％和52.17％;青菜田套种毛芋控制斜纹夜蛾落卵的有效距离约20 m。青菜田套种毛芋并用频振式杀虫灯控害效果更佳,与青菜田(CK)相比,落卵量和幼虫量平均减少73.91％和83.23％,比单用频振式杀虫灯的控害效果提高21.74％。 |
| 英文摘要: |
| The results of 3 year s investigation showed that Prodenia litura (Fabricius) preferred to oviposit on taros in summer and autumn. The average oviposition on taros was 0. 162 lumps/m2 whereas that on Chinese cabbage was 0. 04 lumps/m2. Its oviposition on taros was four times higher than that on Chinese cabbage. The average oviposition and larvae of P. litura were reduced by 39.13% and 52.17% respectively, in Chinese cabbage fields interplanted with taroes compared with that in Chinese cabbage fields (CK). The combination of stroboresonance insecticidal lamps with interplanting resulted in optimum pest control effects so that the average oviposition and larvae of P. litura was reduced by 73. 91% and 83.23% respectively, compared with that in Chinese cabbage fields (CK). The pest control effect of combinatorial practice was raised by 21. 74% compared with that of stroboresonance insecticidal lamps. The effective control distance was 20 - 30 m in Chinese cabbage fields interplanted with taros. |
