摘要: 福鳃钩土蜂和弧丽钩土蜂是蛴螬的重要天敌。两个种在形态上极为相似。本文研究了它们的生物学及其相互区别特征。福鳃钩土蜂的田间寄主为大黑鳃金龟,一年发生1代或两年1代,成蜂主要产卵于寄主后胸及第1腹节之间的腹面,主要寄生3龄幼虫;弧丽钩土蜂田间寄主为暗黑鳃金龟,尚系首次记录。一年发生1代,成蜂产卵于寄主腹部第4~5节之间的侧面。在山东丘陵花生、甘薯栽培区,种植红麻、菜豆等蜜源植物和合理施用化学农药,可以提高钩土蜂的寄生率,控制蛴螬的危害。

Abstract: The biology of two closely related Tiphia species, T. phyllophagae A. et J.
and T. popilliavora Rohwer were describedin this paper. The field host of T.
phyllophagae is large black chafer. Holotrichia oblita Faldermann, its life history
is well synchronized with that of host; with one generation lasting either one
or two years. The egg was deposited singly between the ventral surface of
metathorx and first abdomensegment. The field host of T. popilliavora is black
chafer, H . parallela Motschulsky and its life history is one year one generation.
Its egg was placed singly on the lateral side between 4- 5 abdominal segments. Adult wasps feeds on plant nectar, such as Hibiscus cannabius, Ipomoea batatas, Phaseolus vulgaris etc.
