摘 要 ：用含不同浓度SO₂(40—160ppb)的空气熏气处理过的油菜饲养桃蚜(Myzus persicae),研究SO₂污染对这种蚜虫实验种群生长的影响。结果表明,与对照组相比,40和80ppb SO₂处理组桃蚜的种群增长指数分别提高39.2％和91.％,净繁殖率(R_ō)增加35.5％和83.9％,内禀增长力(r_m)分别升高11.9％和10.5％。使用的SO₂浓度更高时,桃蚜实验种群的这些参数逐渐降低。还比较了在不同浓度SO₂污染条件下,桃蚜实验种群的其它重要参数。

Abstract:This papar deals with performances of laboratory populations of green peach aphid,Myzus persicae(S>ulzer),living on the rape leaves fumigated with SO₂ doses ranging from 40 ppb to 160 ppb. The trend indexes of population, the net reproduction rates(R_ō), and the innate capacities for increase(r_m), of the aphids fed on the rape leaves exposed to SO₂ concentrations of 40 ppb and 80 ppb increased by 39.2,%, 91.0%; 35.5%, 83.9% and 11.9%, 10.5%, res- pectively, compared to those of the insects on the control lea...
