摘　　要：为了探索大草蛉对不同基质的产卵偏好性,选择7种不同颜色与质地的产卵基质,探索在室内自然环境条件下,大草蛉在不同基质上的产卵生物学特性。结果表明,大草蛉对白色基质有产卵偏好性,白纸和白色网布上产卵总量显著高于其他处理,均值分别为675.7和634.0粒;白纸上有效产卵天数最长,平均为33.3 d;但白纸和白色网布上雌成虫寿命并非最长,绿色网布、白纸、透明PET膜、荧光黄网布、黄色网布、棕色养蚕油纸和白色网布的寿命从大到小依次为50.0、49.0、48.7、47.3、42.7、29.7和26.7 d。另外,各处理在4月27日(平均温度为22.7℃,相对湿度为50.5%)产卵量有明显高峰。该研究为提高大草蛉人工饲养效率和卵的收集效率提供理论依据。To explore their oviposition preference for different substrates,seven oviposition substrates of different colors and textures were selected in this study to explore the oviposition biology of Chrysopa pallens on different substrates under indoor natural environmental conditions.The total number of eggs laid on white paper and white mesh was significantly higher than in the other treatments,with a mean of 675.7 and 634.0 eggs,respectively;the number of effective spawning days on white paper was the longest,with an average of 33.3 days;but the life span of female adults on white paper and white mesh was not the longest,and the life span was 50.0,49.0,48.7,47.3,42.7,29.7 and 26.7days in the following order of magnitude:green mesh,white paper,transparent PET film,fluorescent yellow mesh,yellow mesh,brown oiled paper for rearing of silkworms,and white mesh.In addition,there was an obvious spawning peak in each treatment on 27 April(average temperature of 22.7℃and relative humidity of 50.5%).This study provides a basis for improving the artificial rearing efficiency and egg collection efficiency of Chrysopa pallens.
