福腮钩土蜂生物学及其利用的研究

福腮钩土蜂是大黑鳃金龟幼虫的一种外寄生天敌。成蜂以红麻、甘薯蜜腺和菜豆花蜜为补充营养，卵主要产于寄主后胸与第一腹节之间的腹面．单雌平均产卵22粒。幼虫共4龄，咀食寄主组织，只残留头壳，老熟幼虫作茧越冬。生活史有1年1代和2年1代型，成蜂发生时期与大黑鳃金龟发生期相一致。据此提出，在花生田种植蜜源植物，为土蜂提供食物资源．通过从蜂源地助迁土蜂已在邹城市定居．展示有明显的自然控制作用。

STUDES ON THE BIOLOGY OF TIPHIAPHYLLOPHAGAE AND ITS UTILIZATION

Tiphia phgllophag ae Allen & Jaynes. an external parasite attacking the grub ofHoloolrichiaoblita Falderman. develops 1 generation in 1- 2years and overwinters with maturelarva within the cocoon under ground.The occurrence of the wasp highly synchronizes with H. oblita The wasp takes the flower nectar of Poly0onun regnoutria. Hibiscns cammabinus or Ipo-moea batatas as its additional nutrition and can produce 22 eggs per female. Eggs are mainly laidon the body surface between metathorax and lst abdominal segment.Larva of the wasp f with 4instars. feeds on the tissue of the grub and leaves the head capsule of the host eventually. Plant- ing the honey plants around the peanut fields can provide rich honey resource for the wasps. which have been in troduced ln to Zoucheng. and show a promising result for the control of H. oblita.
