The establishment and analysis of the experimental population life table about Trichogramma sppreproduced on artificial eggs
|
Abstract:
The experimental population life tables of Tricho gramma dendrolimi Matsumura and T.confusum reproduced in the artificial eg gs were established by calculating the fecunditiy and survival rate of Trichog ramma by right of the Substantiality Microscope (WILD N8). The result shows th at the parasitizating capacity of Trichogramma population reared in artifici al e ggs is good. The intrinsic rate of natural increase (r m) of them are 0 24 42 and 0 3159 and the former is adapter to being continuously reared in artific ial eggs than the latter For T. dendrolimi Matsumura, the average number of eggs layed per female in artifical eggs is 61 5, and the survival rate of eg g, larvae and pupae 1 00, 0 7020, and 0 9431, respectively. Emergence rate is 0 7387. While for T.confusum, the average eggs one parasite lay in eggs of Coccyra cephalonica is 104 2, and the survival rate of egg, larvae and pup ae 1 00, 0 6454, 0 9383 ,respectively. Emergence rate is 0 7276.
