摘 要:1991—1994年对屎克螂适宜的繁殖条件研究结果:1.土层40cm和60cm的平均温度分别为15.92±6.34℃和15.89±6.08℃;平均土壤含水量分别为26.70±3.74%和23.72±1.88%,使各虫态处于一个几乎恒温恒湿的条件,有利于生长发育与越冬,2.土壤含水量17%、20%、22%、26%和29%,其产卵最多的深度分别在65─70cm,75─80cm,65─80cm,65—80cm和35—50cm,分别占产卵总数的34.16%、42.42%、68.42%、55.40%和90.56%。3.不同土壤的产卵深度,沙壤土以土下45—50cm处最多,占产卵总数的34.78%;沙土以65—85cm最多,占产卵总数的86.67%;粘土以45—60cm最多,占产卵总数的51.11%。on the natural conditions,the average depth of laying egg of Catharsius molossus insandy loam was 44.42± 4.67cm.Under ground,when the depth was 40cm and 60cm,theminimum temperature was 6℃,and the maximum was0.6 25.9℃.The annual average oftemperature was 15.92± 6.34℃and 15.89±0.08℃,and the water content was 26.70±6.34%and 23.72±1.88%,which could make all stages of the insect on the soil condition ofthe constant temperature and humidity,When water content in soil is 17%,20%,22%,26%and 29%,most eggs could be found in the depth of 65─70cm,75─80cm,65 80cm,65 80cm and 35 50cm respectively. As far as soils,it laid more eggs at the depth of 45 50cmin sandy loam, 65 85cm in sandy soil and 45 60cm in clay,and the egg percent was 34.78%,86.67%,and 51.11%,respectively.
