Four kinds of Asian Corn Borer（ACB） eggs masses were obtained by using basements material includevegetable parchment, nontoxic plastics cloth, fresh maize leaves and mimeograph paper. Parasitic characters of fourTrichogramma strains on different ACB eggs were studied in artificial climate box. The results showed that parasiticof Trichogramma to four kinds basements material of ACB eggs had selectivity. Lay and parasitic characters of differ-ent Trichogramma strains to the same ACB eggs were significantly different. Parasitic characters of small eggsTrichogramma was better than those large eggs Trichogramma. When species and strain of Trichogramma was largeeggs or small eggs only, the egg masses parasitism rate of T. chilonis was better than that of T. dendrolimi, but thenumber of eggs laid per female of T. dendrolimi was better than that T. chilonis. It was found that lay and parasiticeffect of the same Trichogramma was best on ACB eggs masses of fresh maize leaves, next was on ACB eggs massesof nontoxic plastics cloth, and that was worst on ACB eggs masses of mimeograph paper. This conclusion offers foun-dation and reference for breeding and application effect evaluation of Trichogramma in the future.
