Influence of Temperature on Parasitic Ability of Tetrastichus brontispae to Its Host
摘要
Abstract
The influences of temperature on the parasitic ability of Tetrastichus brontispae Ferriere with various ages were studied in the laboratory. The results showed that temperature had no significant influence on the sex ratio of T. brontispae. The parasitic ability of T. brontispae to the pupae of coconut leaf beetle Brontispa longissima ( Gestro) was not markedly effected by the temperature of 24 ～28 ℃, while when the temperature decreased further, the parasitic rate of T. brontispae and the quantity of T. brontispae coming from the pupae were significantly decreased. Slightly high temperature was favorable for the parasitic ability of T. brontispae. Within 1～4 days after emergence and mating of T. brontispae, there were no significant changes in its parasitic ability. However, along with the increase of age, the parasitic ability of T. brontispae dropped gradually. The storage of T. brontispae at different temperatures for 1 ～3 days had little effect on its quality, but its parasitic ability would decline sharply after 4 days' storage.关键词
