摘要: 应用酶联免疫吸附试验(ELlSA)来研究捕食作用能较准确地评价捕食性天敌对害虫的控制作用。ELlSA检测表明,不同种类的捕食性天敌对稻飞虱的捕食作用有较大差别,其中以优势种食虫沟瘤蛛和拟水狼蛛的捕食作用最大,阳性反应率与稻飞虱的种群密度有一定的相关关系,但在稻飞虱密度较低的情况下也表现出较高的阳性反应率。

Abstract: Results of enzyme-linked immunosorbent assay (ELISA) showed that therewere significant differences among the predatory effects of different predatory arthropods on whitebacked rice planthopper Sogatella furcifera (Horvath) and brown planthopper Nilaparvata lugens Stal in rice field. In these results, the predation effects of predominant spiders Urnrneliata insecticeps (Boes. Et Str. ) and Pirata subpiraticus Boes. Et Str. , werr thebest, their positive reaction rates were closely correlated with the population density of the planthoppers, and high positive reaction rates occurred even under low rice planthopper density.

Key words: ELISA, predatory arthropods, rice planthoppers
