| 摘要: |
| 普通钩土蜂(Tiphia communis Anen et Jaynes)成虫具咀嚼式口器。上颚发达,镰刀形,长而尖,两侧缘有宽的纵沟,沟的两边均如刀口一样锋利;在上颚的内、外两面都有纵向的细沟,并在上颚基部与两侧缘的宽沟汇合;上颚无特化的端齿与基齿。下颚的内、外颚叶均为膜质的瓣状构造。下唇的中唇舌发达,膜质,上面有细密的横沟;侧唇舌很小。舌膜质,上面有横沟。内唇亦为膜质,形状、大小与舌相似。成虫可咬断寄主附肢或用上颚刺入寄主体内,膜质的内唇、舌和内颚叶等部分可以组成临时的通道,在吸泵作用下,把流出的寄主体液吸入消化道内。所以普通钩土蜂成虫与其幼虫一样可视为金龟子的重要天敌昆虫。 |
