摘要
本文调查研究了油茶宽盾蝽Poecilocoris latus 在杭州市富阳区油茶林的发生危害特点并且通过室内饲养明确其生物学特性.结果表明:2021年和 2022 年,油茶宽盾蝽在富阳区对油茶林的平均危害率分别为 25.67%和27.59%,呈现危害率逐年上升趋势;该虫一年发生一代,若虫共五龄,以老熟若虫越冬,可为害油茶果和新生枝叶;通过饲养观察卵块 35块、共计 423粒卵,孵化后共得到雌虫 209头、雄虫 169头,孵化率为 89.36%;雌虫平均寿命为 69.77 d,雄虫平均寿命为 60.32 d,雌性略高于雄性;成虫危害期为 6-9月,若虫危害期在 4-7月(越冬代)和7-10月.
Abstract
In this paper,the damage caused by Poecilocoris latus in the Fuyang region and its biological characteristics were observed.The results showed that the average hazard rates in Fuyang district were 25.67%and 27.59%,respectively,over the past two years.This insect has one generation per year,and the nymphs have five instars in total.Poecilocoris latus overwinters in the state of mature nymphs and feeds on the fruit or tender leaves of Camellia oleifera.Through breeding,a total of 423 eggs were obtained,with a hatching rate of 89.36%,resulting in 209 females and 169 males.The average lifespan of females is 69.77 days,while males'is 60.32 days.The adult damage period is from June to September,and the nymph damage pe-riod is from April to July(overwintering generation)and from July to October.
