摘要
就不同浓度的橡胶籽提取物对新菠萝灰粉蚧的选择性和非选择性忌避作用进行试验测定。选择性忌避试验结果表明:橡胶籽提取物300倍液(0.667ml/L)比其他浓度的忌避效果好,达到84.3%。非选择性忌避试验结果表明:以功夫3000倍液(0.008ml/L)作对照时,对新菠萝灰粉蚧的忌避率在900倍液(0.222ml/L)效果较好。
The article talks about determining the selective and the non-selective repellent ettect to the Dysmicoccus neobrevipes Beardsley with different concentration of extracts of rubber seed.The results of the selective repellent tests showed that： the repellent effect of the extracts of rubber seed with 300 times （0.667ml/L） was better than any other effects with different concentrations, reached 84.3% . The results of the non-selective repellent tests showed that： compared with Lambda-cyhalothrin EW with 3000 times （0.008ml/L） as control group, the repellent rate on D.neobrevipes was better on the concentration of 900 times （0.222ml/L）.
