When establishing an efficient banker plant system consisting of rice plant, alternate host Aleurocybotus indicus David and Subramaniam (Hemiptera: Aleyrodidae), and natural energy Encarsia sophia Girault and Dodd (Hymenoptera: Aphelinidae), searching the most suitable rice plant to culture alternate host is the primary step. The population fitness of A. indicus feeding on different rice cultivars was measured with the method of two-sex life table. The results showed that the developmental time of A. indicus feeding on Changyou (CY, 7.2 d), Hangyou (HY, 6.8 d), and Guangshan (GS, 6.9 d) rice plants was shorter than when feeding on Ningjing (NJ, 8.0 d) and Luoyou (LY, 8.0 d) rice plants. The net reproductive rate (R0) of A. indicus feeding on the CY (47.3 eggs), JJ (Jinjing, 42.1 eggs), and NJ (47.9 eggs) was greater than that when feeding on the LY (24.7 eggs) rice plant. The intrinsic rate of increase (r) seen in CY (0.1718 d−1) and JJ (0.1638 d−1) plants was significantly greater than that seen in LY (0.1378 d−1). In conclusion, the data show that CY and JJ rice plants were the most suitable hosts for breeding A. indicus.

Aleurocybotus indicus (Hemiptera: Aleyrodidae) 饲喂不同水稻品种的繁殖性能

在建立由水稻、备用寄主 Aleurocybotus indicus David 和 Subramaniam(半翅目:Aleyrodidae)以及天然能源 Encarsia sophia Girault 和 Dodd(膜翅目:Aphelinidae)组成的高效银行家植物系统时,寻找最适合培养备用寄主的水稻植物是首要步骤。采用两性生命表法测定了以不同水稻品种为食的A. indicus种群适应度。结果表明,A. indicus 取食昌油(CY,7.2 d)、航油(HY,6.8 d)和广山(GS,6.9 d)水稻植株的发育时间短于取食宁靖(NJ,8.0 d) 和洛油 (LY, 8.0 d) 水稻植物。A. indicus 以 CY(47.3 枚卵)、JJ(Jinjing,42.1 枚卵)和 NJ(47.3 枚卵)为食的净繁殖率 (R0)。9 个鸡蛋)比喂食 LY(24.7 个鸡蛋)水稻时要多。在 CY (0.1718 d-1) 和 JJ (0.1638 d-1) 植物中观察到的内在增长率 (r) 显着大于在 LY (0.1378 d-1) 中观察到的。总之,数据表明,CY 和 JJ 水稻植物是最适合培育 A. indicus 的宿主。
