日本佳盾蜾蠃Euodynerus nipanicus(Schulthess)是一种重要的独栖捕食性天敌昆虫,对我国南方林区鳞翅目蛾类害虫的控制具有一定作用。本文报道了日本佳盾蜾蠃的形态特征、生活史及幼虫和成虫的行为等生物学特性。该蜂在江西赣州地区1年发生4代,以滞育的老熟幼虫在巢管虫室内越冬,滞育期约190 d。翌年的4月下旬成虫开始外出活动,主要包括交配、筑巢、产卵、捕食等行为。通过野外收集筑巢巢管,室内饲养观察等,发现该蜂的卵近似微弯的长圆柱形,长2.912±0.127 mm,卵期2-4 d,平均2.5±0.99 d;非越冬幼虫期8.1±0.99 d;预蛹期4.3±0.48 d;蛹期7.4±0.84 d;雌雄比约为2.95∶1。本研究丰富了日本佳盾蜾蠃的生物学基础知识,为进一步利用该蜂防治南方林区鳞翅目蛾类害虫提供了依据。
Euodynerus nipanicus (Schulthess) is an important predatory natural enemy insect and plays a certain role in the control of Lepidoptera moth pests in southern China. This article reports on the morphological characteristics, life history, and the biological characteristics of larvae and adult worms in Jiandu, Japan. The bee in the Jiangxi Ganzhou area occurred 4 years a year, diapause of mature larvae in the nest pipeworm indoor winter, diapause of about 190 d. In late April of the following year, adults begin to go out activities, mainly including mating, nesting, spawning and predation. The nests of the bees were found to be slightly cylindrical in shape with a length of 2.912 ± 0.127 mm and the egg period of 2-4 days with an average of 2.5 ± 0.99 days. The nonwintering larvae period 8.1 ± 0.99 d; pre-pupal stage 4.3 ± 0.48 d; pupal stage 7.4 ± 0.84 d; the male-female ratio was about 2.95: 1. This study enriched the basic knowledge of the biology of Jigula japonica in Japan and provided the basis for further utilizing the bee to control the lepidopteran moth pests in the southern forest.
