摘　　要：对椰心叶甲啮小蜂羽化、求偶、交配、产卵、繁殖现象进行了观察研究。结果表明,补充营养对雌蜂的寿命和繁殖力均有影响。没有补充营养的情况下,雌蜂的平均寿命为2.48 d,一生可产21.43粒卵;每天补充10%蜜糖水,且雌蜂与寄主(椰心叶甲初蛹)比例为1:3时,雌蜂平均寿命为13.43 d,一生可产53.6粒卵;每天补充10%蜜糖水,且雌蜂与寄主(椰心叶甲初蛹)比例为1:1时,雌蜂平均寿命为14.78 d,一生可产42.5粒卵。椰心叶甲啮小蜂对水椰八角铁甲蛹的寄生率为82.25%,平均每寄主出蜂量为12.24头。Eclosion, courtship, mating and oviposition behaviors of Tetrastichus brontispae were studiod in this article. Results showed that supplying nutrition would influence the longevity and fecundity of the female T. brontispae. Without exogenous nutrition supply, the average longevity and egg production per female was 2.48 days and 21.43 individuals respectively. While supplied with 10% honey （v/v） and the ratio of female to host （ young pupae of T. brontispcte） was 1：3, the average longevity and egg production per female was 13.43 days and 53.6 individuals respectively. When suppliod with 10% honey （v/v） and the ratio of female to host （ young pupae of T. brontispcte） was 1 ： 1, the average longevity and egg production per female was 14.78 days and 42.5 individuals respectively. The parasitism rate of T. brontispae to the pupae of Octodonta nipae （Maulik） was 82.25%, the average number of adult T. brontispae per parasitized pupae was 12.24 individuals.
