摘要: 为明确天敌昆虫益蝽(Picromerus lewisi)雌成虫的产卵行为,筛选出适合雌成虫产卵的介质,在室内采用网室法观察了益蝽成虫的产卵行为,同时分析益蝽雌成虫在折叠与未折叠处理的牛皮纸、硫酸纸、A4打印纸和纱布4种介质上的产卵量、卵块集中度、产卵持续时间和卵的孵化率。结果显示,益蝽雌成虫的产卵行为表现为寻找产卵位置、产卵和停歇3个步骤;雌成虫能多次产卵且卵以卵块形式分布;雌成虫对折叠纱布具有较高的产卵选择性,在折叠纱布上的产卵集中度最高,为38.86%,产卵量(49.33粒)和总产卵量(140.87粒)较大,产卵持续时间最长,达38.27 d;折叠与未折叠的产卵介质对益蝽卵的孵化率无显著影响,牛皮纸、硫酸纸、A4打印纸、纱布4种介质上卵的孵化率均在90.00%以上。综上,天敌昆虫益蝽雌成虫产卵量大且卵的孵化率高,折叠纱布是室内规模繁育益蝽的有效产卵介质。

Abstract: To clarify the oviposition behavior of the natural enemy insect Picromerus lewisi and screen the suitable medium for female oviposition,this study was carried out to observe the oviposition behavior of P.lewisi using net room method in laboratory. At the same time,the egg mass concentration,oviposition quantity,oviposition duration and egg hatching rate on four mediums(folded and unfolded) were analyzed,including kraft paper,sulfuric acid paper,A4 printing paper and gauze. The results showed that oviposition behavior of P.lewisi adults was mainly divided into three steps:finding a suitable oviposition site,ovipositing and resting.P.lewisi adults could lay eggs multiple times and eggs were distributed in the form of egg mass.Female adults had higher preference for oviposition on folded gauze.The highest concentration of oviposition on folded gauze was 38.86%,the maximum oviposition quantity and total oviposition quantity were 49.33 and 140.87,respectively,and the duration of oviposition was 38.27 d.Oviposition mediums(folded and unfolded)had no significant effect on the hatching rate of eggs.All of the hatching rate of eggs on four mediums including kraft paper,sulfuric acid paper,A4 printing paper and gauze exceeded 90.00%.In summary,the oviposition quantity of P.lewisi female adults is large and the hatching rate of eggs is high.The folded gauze is an effective oviposition medium for indoor large-scale breeding of P.lewisi.
