【摘要】 通过对生物学特性的研究,探明了在27℃条件下黄粉虫各虫态历期和成虫寿命。成虫产卵期达60d以上,日产卵量保持相对稳定,为6～10粒/d;成虫产卵量直接受密度影响,夜间产卵量多于白天。更多还原

【Abstract】 The results of test identified the interim of different developing stage of Tenhrio notlitorlinn and the life span of adult under the temperature of 27 ℃.The adult egg laying stage could be over sixty days, the number of eggs was relatively average about six to eight per day. The density showed a direct influence on the number of eggs, and the number at night is more than that at daylight.更多还原
