概要 Neochrysocharis okazakii Kamijo (Hymenoptera: Eulophidae) is endoparasitoid capable of developing on several Liriomyza leafminer species, and a dominant parasitoid associated with the stone leek leafm...iner Liriomyza chinensis (Kato) (Diptera: Agromyzidae) in Vietnam. Its biology on L. chinensis was studied in the laboratory at a constant temperature of 25℃ and a photoperiod of 16L: 8D. Total developmental time from egg to adult emergence was 12.1 and 12.2 days for males and females, respectively. Pupal development lasted slightly shorter than the combined egg and larval stages. The females laid a mean of 60.1 eggs and caused other 36.4 host larvae died during an average lifespan of 20.1 days. Fecundity peaked at age 3 days. The offspring sex ratio was female-biased as 27.8% males. The intrinsic rate of natural increase (γ^m) (day ^{-1}), net reproduction (Ro), and generation time (T) (day) were 0.219, 17.7 and 40.3, respectively.続きを見る
