Observation on the first three times of flying, after the wasps being released. revealed that the first flying was an escape style and not showed preference to land on any special crops. 81. 82% wasps landed on corn leaves at the second flying but stayed for just about 3 min. In the sweet potato-peanut field, 51.43% wasps landed on sweet potato in contrast with 48.57% landed on peanuts and in the afternoon 33. 53% on sweet potato compared with 76.4% landed on peanut field. Majority preferred landing on peanut field on the third flying in both type fields of inter-cropping. Behavior of flying was different between morning and afternoon. The time length between two flies showed that wasps were more active in the morning than in the afternoon.展开更多
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...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。展开更多
