在建立由水稻、交替寄主粉虱Aleurocybotus indicusDavid和Subramaniam（半翅目：粉虱科）和自然能虫Encarsia sophia Girault和Dodd（夜蛾科）组成的高效的银行种植系统时，寻找最适合培养交替寄主的水稻植株是首要步骤。A.用双性生命表法测定了印度螟在不同水稻品种上的取食量。结果表明：A.取食长优、杭优和光山稻的时间分别为7.2 d、6.8 d和6.9 d，而取食宁靖和罗优稻的时间分别为8.0 d和8.0 d。A.取食CY（47.3粒）、JJ（金晶，42.1粒）和NJ（47.9粒）的籼稻的成虫产卵量大于取食LY（24.7粒）的水稻。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）显著大于LY（0.1378 d−1）。因此，CY和JJ水稻是繁殖A. indicus。
When establishing an efficient banker plant system consisting of rice plant, alternate hostAleurocybotus indicusDavid and Subramaniam (Hemiptera: Aleyrodidae), and natural energyEncarsia sophiaGirault and Dodd (Hymenoptera: Aphelinidae), searching the most suitable rice plant to culture alternate host is the primary step. The population fitness ofA. indicusfeeding on different rice cultivars was measured with the method of two-sex life table. The results showed that the developmental time ofA. indicusfeeding 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) ofA. indicusfeeding 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 breedingA. indicus.
