Objective: Basilepta melanopus is a defoliator of Camellia oleifera in southern China. The sexual selection, mating, and fecundity of B. melanopus (Coleoptera: Chrysomelidae) were studied to determine the pest occurrence mechanisms. It may help in the development of sex pheromone used in trapping method for controlling the pest.Method: Mature overwintered larvae were collected from the soil under the trees of Camellia oleifera in Yongan (Changsha, Hunan), and reared in the laboratory to obtain adults for this experiment. Mating pairs of newly e...

【目的】角胸叶甲(鞘翅目: 叶甲科)是危害油茶叶子的重要害虫。研究角胸叶甲性选择和交配及产卵等行为学特性,为性干扰诱杀技术提供理论依据。【方法】从湖南永安镇油茶林土壤中挖出越冬代幼虫在室内连续繁殖,羽化后单头饲养,配对后观察其交配行为(记录交配前、交配和交配后3个阶段的交配行为) 、交配产卵日节律(统计白昼和夜晚的交配次数和产卵量) 、长期配对下成虫体质量及交配经历对性选择的影响。【结果】成虫羽化5 ~ 6天后开始交配,日平均交配(5 ± 4.2)次,交配持续时间最短1 min,最长可达40 min,平均交配持续时间(18.88 ± 9.3) min。交配后6 ~ 7天开始产卵,平均每雌产卵量为(275.5 ± 13...
