摘　　要：实验在室内温度为(26±1)℃、相对湿度为75%±5%、自然光照的条件下,以四季豆、大豆、饭豇豆、苜蓿、转基因抗虫棉99B和非转基因棉石远321为食料,用生命表方法系统研究了不同寄主植物对中黑盲蝽实验种群生长发育、存活及繁殖的影响。结果表明中黑盲蝽(Adelphocoris suturalis)取食6种不同的寄主植物时,各虫态的发育历期、存活率、成虫寿命、产卵前期、产卵期、产卵量、5龄若虫体重等均有显著差异。用生命表参数综合评价表明,四季豆最适合中黑盲蝽的生长发育及繁殖,其次分别为苜蓿、转基因抗虫棉99B、非转基因棉石远321、饭豇豆、大豆,同时也表明转基因抗虫棉对中黑盲蝽无显著抗性。田间取食选择性试验表明,中黑盲蝽喜食饭豇豆和豇豆,可在棉田周围种植饭豇豆、豇豆作为诱集作物。The effects of diverse host plants on the development, survival and fecundity of the cotton mirid Adelphocoris suturalis Jakovlev （Hemiptera： Miridae）was evaluated using life table methods. A. suturalis was reared on kidney bean, soybean, cowpea, alfalfa, transgenic Bt cotton 99B and non-transgenic cotton Shiyuan 321 in the laboratory with natural illumination, temperature 26℃± 1℃ and the relative humidity 75% ± 5%. The mean duration of development, survival rate of each stadium, body mass of 5^th instars, longevity of adults, preoviposition duration, oviposition duration, and fecundity of female A. suturalis were significantly different amongst the six host plant types. Based on the life-table parameters, host plant suitability for development and reproduction of A. suturalis was highest on kidney bean, followed by alfalfa, transgenic Bt cotton 99B, non-transgenic cotton Shiyuan 321, cowpea, and lowest on soybean. The present study indicates that transgenic Bt cotton has no resistance to A. suturalis. In the field, A. suturalis preferred to feed on cowpeas and this host plant could be planted around the cotton field as a trap crop.
