小花蝽Orius minutus是棉红蜘蛛的重要天敌之一。为了探讨对小花蝽的保护和利用,我们于1977～1978年对它的生物学特性和保护利用进行了初步的研究。现将其各虫态的主要形态特征、生物学特性和人工助迁防治棉红蜘蛛的效果叙述如下。一、形态特征成虫体黑色,体长约2.2毫米。雌成虫腹部两侧对称,产卵管贴于腹部后方正中,由镰刀状产卵辦组成。雄成虫腹部两侧不对称,腹末数节向右扭曲,其左侧有一螺旋形抱握器。卵茄子形。产于嫩茎或叶柄内,卵盖外露。
Orius minutus is one of the important natural enemies of cotton spider mites. In order to explore the conservation and utilization of the water bug, we conducted a preliminary study of its biological characteristics and protection and utilization from 1977 to 1978. Now its main morphological characteristics of each insect state, biological characteristics and artificial removal of the effect of cotton spider mite described below. First, the morphological characteristics Adult body black, body length of about 2.2 mm. Female adult abdomen on both sides of the symmetry, oviposit tube affixed to the back of the abdomen, by sickle-like spawning office. Adult male abdomen on both sides of the asymmetry, the end of the dorsal section of the right twist, the left side of a spiral grip. Eggplant egg-shaped. Produced in young stems or petioles, ovoid exposed.
