有关土壤水分对棉铃虫蛹存活的影响，前人已做过许多工作。张孝羲等［１］报道了土壤含水量对棉铃虫化蛹与羽化影响的室内模拟试验，吴子江［２］报道了大田土壤自然含水量对棉铃虫蛹存活的影响，结果均表明土壤含水量越高，棉铃虫蛹存活率及羽化率越低。但土壤水分对棉铃...
The impact of soil moisture on the survival of the cotton bollworm pupae, many people have done a lot of work. Zhang et al. [1] reported an indoor simulation experiment on the effect of soil water content on pupae and emergence of cotton bollworm. Wu et al. [2] reported the effect of natural soil moisture on the survival of the cotton bollworm pupae. The results showed that the higher the soil moisture content The survival rate and emergence rate of H. armigera pupae were lower. But the soil moisture on the cotton boll ...
