Effect of Rearing Condition without Soil Medium on Growth,Development and Reproduction of Eupolyphaga sinensis

In order to reform the technique of the manpower feeding,predigest the method of breeding,reduce the intension of working,increase the yield and quality of E.sinensis,E.sinensis the rearing without soil medium was tested.Under the rearing conditions with and without soil medium,the weight,ecdysis rate,death rate and oviposition pattern of female E.sinensis were measured for 2 months.The results showed that:(1) When food was sufficient,the weight increasing rate of E.sinensis fed with and without soil medium was respectively 39.42% and 47.06%;(2) The ecdysis rate of E. sinensis fed with and without soil medium was respectively 13.36% and 15.12%.(3) The egg-pouches that were laid by the E.sinensis fed without soil medium were big and full,the average weight of egg-pouches was higher than that with soil medium;(4)The total death rate without soil medium was 15.56%,but that with soil medium was 29.17%.Therefore,the rearing technique without soil medium should be applied for E.sinensis rearing.
