Effects of Mythimna separata on Development and Fecundity of Harmonia axyridis
摘要
Abstract
The eggs,young and old larvae of Mythimna separata were used as prey for Harmonia axyridis in this study to assess their effects on the growth,development and reproduction of H.axyridis.The results showed that there were significant differences in the developmental duration,adult weight,survival rate and reproduction of H.axyridis fed on the three preys.The developmental duration of the whole larval stage of H.axyridis in the egg group(9.85 d)was significantly shorter than that in the young larva(10.45 d)and the old larva(11.28 d)groups,but that of the pupal stage(5.80 d)was significantly prolonged in the egg group.The pupal and adult weight of H.axyridis of the three groups showed no significant difference,except that the female adult weight(30.39 mg)was significantly higher in the egg group.The overall larval survival rate of H.axyridis in the egg group(100％)was significantly higher than that in the 1st—2nd instar larva(83.33％)and the 5th—6th instar larva(33.33％)groups.The pupal survival rates in the egg and 1st—2nd instar larva groups(100％)were significantly higher than that in the 5th—6th instar larva group(50.00％).Only the egg group H.axyridis deposited eggs normally,with a maximum fecundity of 1585 eggs/female,whereas the larvae group H.axyridis only exhibited mating behaviors.The current results indicate that all the three preys can support the growth of H.axyridis,but only the eggs of M.separata can produce fertile H.axyridis.It is feasible to use M.separata eggs as prey for mass rearing of H.axyridis.关键词
