黑拟谷盗Tribolium madens(Charp.),是新疆、甘肃、青海、宁夏等地面粉厂害虫,亦能为害小麦的胚乳。国内尚未报道此虫的生物学特性的论文。其卵在17℃以下,22、27、30、35、37、40℃不同温度及相对湿度40％、70％条件下处理后,卵孵化率有明显的差异。可分三个温区:17℃以下及40℃时卵孵化率为O,37℃孵化率为50％左右,其它温度下黑拟谷盗卵有70％以上孵化。从卵期来言,温度低卵期长,温度高卵期短。湿度对卵孵化率无影响。在温度17℃以下及37℃时黑拟谷盗幼虫不能进入蛹期。赤拟谷盗、杂拟谷盗在37℃时却有部分幼虫化蛹。27℃黑拟谷盗、杂拟谷盗幼虫死亡率为10％,赤拟谷盗在20％以下。黑拟谷盗个体幼虫在此温度条件下需要32—40天才能全部化蛹,群聚生活的幼虫二个月内仍处于幼虫期。赤拟谷盗、杂拟谷盗个体与群体幼虫化蛹天数的差异不如黑拟谷盗明显。相对湿度70％,温度范围20—30℃条件下黑拟谷盗幼虫发育随温度升高而加快,幼虫期缩短。黑拟谷盗蛹期在35℃为4.3天,27℃为5.6天,22℃为20天。黑拟谷盗卵孵化卒,幼虫发育仅仅在低湿条件下一个很狭窄的温度范围25—30℃内最佳。卵期、幼虫发育期,蛹期均短。且幼虫具有群聚性而延长幼虫期的特性,从而导致在西北某些地区偶而发现黑拟谷盗成虫的现象。
Tribulation Tribolium madens (Charp.) Is a pest of the flour mills in Xinjiang, Gansu, Qinghai and Ningxia, as well as the endosperm of wheat. The article has not yet reported the biological characteristics of this worm. Eggs hatched at 17 ℃, 22,27,30,35,37,40 ℃ under different temperatures and relative humidity of 40%, 70% under the conditions of treatment, egg hatching rate was significantly different. Can be divided into three temperature zones: below 17 ℃ and 40 ℃ egg hatching rate of O, 37 ℃ hatching rate of about 50%, other temperatures black to be pigeon eggs have hatched more than 70%. From the egg period, the temperature is low, long egg, egg temperature is short. Humidity has no effect on egg hatchability. At temperatures below 17 ° C and at 37 ° C, the black curly larvae could not enter the pupal stage. Red imitation Brava, miscellaneous grains at 37 ℃ when there is some larvae pupation. At 27 ℃, the death rate of black curd, miscellaneous grains and turpentine larvae is 10%, and that of red currant is below 20%. Black intends to Solitary Curlew individual larvae at this temperature requires 32-40 days to fully pupate, group life larvae are still in larvae within two months. The difference between the numbers of pupae in the groups of red-foxtail millet, miscellaneous grains and larvae was not as obvious as that of black millet. Relative humidity 70%, temperature range 20-30 ℃ under the conditions of Black Curio larvae development accelerated with temperature, larval period shortened. Black pobium pupal stage at 35 ℃ for 4.3 days, 27 ℃ for 5.6 days, 22 ℃ for 20 days. Black Egg Pigeon eggs hatch, larval development is only a very narrow temperature range of 25-30 ℃ in low humidity conditions within the best. Egg stage, larval development, pupal period are short. And larvae have clustering to extend the larval period of the characteristics, resulting in some parts of Northwest occasionally found black albino adult phenomenon.
