Chrysomya megacephala Fabricius (Diptera:Calliphoridae) belongs to Chrysomya genus, Calliphoridae family, Diptera order, and was used in forensic entomology for obtaining biological evidence to determine time, location, and causes of death in criminal case because the larvae often feed on meat and corpse. On the other way, C. megacephala was a good pollinator for plants. The protection agriculture developed rapidly and was noticed increasingly by many farmers for considerable economic efficiency. Relative isolated environment prevented the plant from the pollination insects made the increasing potential limited and the quality receded. Based on the need of effective and more pollination insects in protection agriculture, C. megacephala was studied on its artificial rearing technology, foundation of pollinating behavior, and pollinating effects. The main results were as follows:1 Research on larval food of C. megacephalaThe different dosage of fish meal in the larval feed of C. megacephala influenced larval body length. The protein feed could promote its growth was concluded from the fact that the preliminary body length of larvae increased quickly. The orthogonal test showed that the optimum feed was 15% fish meal, 1% sheep dung, 10% maize meal, 20% bean residue, and 54% bran. The feed with 60% water content fermented for 4d was best.2 Research on the rearing density of C. megacephalaThe length and weight of C. megacephala larvae were different between different density rearing. In the later period a phenomenon that the body length of larvae reduced was observed. The weight of pupae decreased when the rearing density increased. When larvae of C. megacephala reared under high density, the amount of pupae present at the same time was low, and vice versa.Under the different raising density, there were no significant differences between the preoviposition period, oviposition period of C. megacephala female. However, significant difference with average eggs per female was found. The amount of eggs under low raising density was high in new emerge days, but decreased gradually. The amount of eggs under high raising density was successively a little lower.3 Effects of food on fecundity of C. megacephalaOviposition matter (bran) added Urea and Ammonia could allure more adults of C.megacephala to lay eggs, and the corrupt fish flesh as well.C. megacephala adults fed on the rape pollen, powered milk, granulated sugar,...
