摘要
文章分析研究了锡林郭勒草原不同季节温度变化对蝗虫卵的生存、孵化出土以及蝗蝻摄食和成长的影响。结果表明,秋季首次寒潮天气出现的时间越早,对蝗卵的影响越大,冬季低温能减少蝗虫卵的成活率,春季至夏初的温度升高,不仅提高蝗虫卵孵化率,而且能促进蝗蝻和初龄成虫的成活。
The article studies the effects of season＂ s temperature change in Xilingole grassland on locust ovum survival, hatch, larva feeding and growth. The result shows that more earlier of the appearance time of autumn first cold wave, more hurt to ovum; winter low temperature could increase ovum cold mortality; during spring to summer temperature increase, not only improve hatch rate, but also accelerate survive rate of larva and early imago.
