摘    要:白蜡虫阔柄跳小蜂Metaphycus ericeri Xu et Jiang在昆明地区一年发生5代,以3、4、5龄幼虫和蛹在白蜡虫雌成虫体内越冬。该蜂的发育起点温度和有效积温分别为11.45℃和552.93日度。18 ℃、21℃、24℃、27℃和30℃恒温条件下的平均世代历期分别为 66.87天、42.27天、35.56天 、30.84天和27.81天。成虫需取食蜜露或白蜡虫雌虫体液作补充营养。性比为1.75~2.88:1(平均2.25:1)。产卵前期2~3天。开始产卵后的2~5天产卵量占总产卵量的62.21%。 27℃的产卵量和产卵率分别为19.31粒和89.81%。18℃时仅4.37粒和18.56%。15℃时不产卵。补充营养、性别和产卵与否对成虫寿命有显著影响。幼虫共5龄。1~4龄以寄主体液和组织为食。5龄幼虫不取食,3~4天后化蛹。

Abstract:Metaphycus ericeri Xu et Jiang is an important parasitic wasp of female white wax insect, Ericerus pela Chavannes. The parasitic wasp has 5 generations per year in Kunming and overwinters as 3rd, 4th, 5th instar larvae and pupae in host body. The thermal threshold and thermal sum for the development are 11.45℃and 552.93 daydegrees respectively. The mean generation times at 18℃, 21℃, 24℃, 27℃ and 30℃ are 66.87d,47.27d,35.56d,30.84d and 27.81d respectively. The adults sucked honey dew and the host body fluid for its complementary nutrition. The sex ratio is 1.75~2.88:1 (mean 2.25:1). The pre-oviposition period is 2~3 days. At 18℃,21℃,24℃,27℃ and 30℃, the number of eggs produced per female is 4.37,13.29,18.16,19.31 and 15.14,and percentage of eggs produced is 1856%,64.14%,83.49%,89.81% and 75.81%respectively. The female wasp doesn't oviposit at 15℃. The adult longevity is influenced by food, sex and oviposition. The larvae undergo 5 instars. The 1st~4th instar larvae live on the host body fluid and tissue. The 5th instar larvae stop feeding, excrete and pupate in the host body.
Keywords:Metaphycus ericeri    life history  thermal threshold  generation time  behaviour
