摘要
间斑寇蛛幼蛛过冬和早期饲养管理是人工饲养的关键。通过比较不同保存温度和不同保存时间下过冬幼蛛的孵化率、存活率和平均体质量，研究了间斑寇蛛幼蛛过冬的规律，并探讨了相对湿度、环境温度和食物种类对幼蛛离开卵囊后的早期生长发育的影响。结果表明：4℃左右是比较理想的卵囊保存过冬温度，但在此温度下保存7个月后存活率开始下降，到13个月幼蛛存活率降为零；卵囊放入低温保存前需在室内放置一段时间（约2个月）以使卵粒孵化成幼蛛；4℃左右下过冬的幼蛛离开卵囊后，在相对湿度55％～60％、环境温度25℃～30℃的条件下，用黄粉虫喂养4周后体质量增长40余倍，成活率达80％以上。
Overwintering and early rearing of Latrodectus tredecimguttatus baby spiders is the key of artificially rearing the spiders. Through the comparison of the hatch rate, survival rate, and average body mass of overwintered baby spiders under different preservation temperature and duration, this paper studied the overwintering pattern of L. tredecimguttatus baby spiders, and the effects of relative humidity, environmental temperature and food on the early growth and development of the baby spiders after leaving egg bags. The results showed that the optimal temperature for the preservation and overwintering of the egg bags was around 4 ℃, but the survival rate of baby spiders decreased gradually after 7 months of the preservation under this temperature, and got to zero after 13 months. To let the eggs hatch out, egg bags should be placed indoor for a period of time （ around 2 months） before preserved at low temperature. After left egg bag and reared with Tenerio molitor for four weeks, the average body mass of overwintering baby spiders under 55% -60% relative humidity and 25 ℃ -30 ℃ increased by 40- or more fold, with a survival rate greater than 80%.
