摘要：利用人工气候箱,按照正交设计方法,设置了8种不同温度、湿度、光照条件组合,运用生命表技术,对胭脂虫进行了种群动态研究。研究结果表明:15℃以下,胭脂虫卵有少量孵化,但不能完成世代;20、25、30℃条件下胭脂虫能完成世代。从培育的胭脂虫的怀卵量、种群趋势指数及大小方面比较,以温度25℃、相对湿度60%和80%、光照强度980lx和60lx的组合条件为好;胭脂虫的雌雄性比远大于1:1,环境因子对性比具有较大的影响;胭脂虫的种群趋势指数一般大于20,平均约40,对培育十分有利;发育起点温度为9 0℃,世代有效积温为822 9日度;多因素方差分析结果显示,温度为影响胭脂虫发育的最显著因素,而湿度和光照的影响相对较小。
A study on the population dynamics of cochineal insect in the lab is carried out by using artificial climate cases The method is to set 8 kinds of combinations of temperature, humidity and light according to orthogonal design and then establish the life tables of the insect The temperature has four levels:15, 20, 25 ℃ and 30 ℃, and the relative humidity has two levels: 60% and 80%, while the light also has two levels: 980 lx and 60 lx Through observations and analysis of several generations, the results indicate that the cochineal insect cannot finish generations under 15 ℃ associated conditions, while at associated conditions of temperatures 20?25?30 ℃, the insect can finish generations, but comparing from the amount of eggs, generation inclination indexes and the sizes of the female adults, 25 ℃ associated conditions are the best The results also indicate that average hatching percentage of egg is about 50 and the survival percentage is probably 70 at 20～30℃, and that the number of females is more than that of the males in the cochineal populations,environmental factors have large effect on the sex ratio of the cochineal insect and the generation inclination index usually surpasses 20 The development starting point temperature of the insect is 90 ℃, and effective accumulated temperature of one generation is 8229 daydegrees The results of multifactor analysis of variance show that temperature is the most remarkable factor to affect development of the insect
