【摘要】：齿缘刺猎蝽是国内广泛分布的一种捕食性天敌昆虫,能捕食多种农林业害虫。为了充分利用该虫,我们对齿缘刺猎蝽的生活史、形态特征和行为进行了研究。结果表明,齿缘刺猎蝽在湖南一年发生一代,以成虫越冬;5月份产卵,若虫4龄,初孵若虫黄褐色,2-4龄若虫由黄绿色到淡绿色,4龄若虫可见明显白色翅芽,8月份羽化为成虫,成虫灰褐色。各龄若虫和成虫体表均分布有较多棘或刺。成虫平均寿命长达312.5 d,不太活跃,有一定的飞行能力,取食和交配的时间较长,整个产卵期产卵量为每头雌虫35-41粒。
[Abstract]:As a kind of predatory natural enemy insect widely distributed in China, it can prey on a variety of agricultural and forestry pests. In order to make full use of the insect, we studied the life history, morphological characteristics and behavior of the bug. The results showed that there was a first generation in Hunan Province, and the eggs were laid by adults in May, and the nymphs at the 4th instar of nymphs were hatched from yellowish green to pale green. The white wing buds of the nymphs appeared as adults in August. Adults are grayish brown. There were more spines or spines on the body surface of nymphs and adults at all ages. The average life span of adult is 312.5 days, it is not very active, it has certain flying ability, feeding and mating time is longer, the number of eggs per female is 35-41 during the whole spawning period.
