摘要
在(25±1)℃、相对湿度(RH)70%±5%、光周期L∶D=13∶11条件下,用小叶龙船花花粉、豇豆花粉、扶桑花粉、台湾相思花粉、棉花花粉、玉米花粉饲喂卵圆真绥螨。结果表明,6种花粉饲喂均能使卵圆真绥螨完成生长发育及繁殖,其中豇豆花粉饲喂卵圆真绥螨时发育历期最短,为(5.07±0.06) d;存活率最高,为93.75%±3.05%;净增殖率最大,为16.78±1.22;单雌总产卵量第二,为(32.33±2.17)粒。综上所述,豇豆花粉较适宜卵圆真绥螨生长发育和繁殖。
In order to assess the life history of E. ovalis feeding on Ixora chinensis Lam. pollen, Vigna unguiculata (Linn.) Walp pollen, Hibiscus rosa-sinensis pollen, Acacia confusa pollen, Gossypium spp. pollen and Zea mays Linn. sp. pollen, we compared the developmental periods, survival rate, total egg production and the life history parameters of E. ovalis. The results showed that the growth and reproduction of E. ovalis was achieved by feeding on the six kinds of pollen. Among them, the shortest developmental period (5.07±0.06) d, the highest survival rate 93.75%±3.05%, the highest net reproductive rate 16.78±1.22, and the second biggest total egg production 32.33±2.17 were found when feeding on V. unguiculata under the condition of (25±1)℃, RH 70%±5%, L∶D=13∶11. The results showed that the pollen of V. unguiculata was more suitable for the growth and reproduction of E. ovalis.
