【摘要】 实验表明,感染有根结线虫的土壤或植株,施用家蝇幼虫饲料残渣及其浸渍液,能显著减少线虫虫口密度;并使病株对病虫害抗性提高,明显促进生长.用1∶4浓度浸渍液直接处理多种植物线虫成虫和根结线虫幼虫,4～5d可致死亡.这与饲料残渣中含有蝇幼虫分泌物及其蜕的皮等几丁质物质有关.蝇幼虫饲料残渣既具有优质有机肥,又具有防治病虫害、促进植物生长的双重功效.更多还原

【Abstract】 In this paper, it was sound that foodresidue of housely larva and its soak solution can significantly decrease the rootknot nematode population density in infected soil and plants, enhance plants’ disease resistance and remarkably facilitate their growth. Treated directly with soak solution which was diluted by 5 times, plantparasitic nematodes and rootknot nematode larva were killed within 4～5 days. The effect of food residue is due to its containing of larva’ secretion and some chitin substance,such as ecdysis and so on.Our results suggested that housely larva food residue is a good organic fertilizer which can not only promote plant growth but also control pests.更多还原
