Effects of different host plants on the host selection and development of B-biotype Bemisia tabaci
The selection of B-biotype Bemisia tabaci from among tomato,cabbage and sweet pepper and the effects of those host plants on B-biotype Bemisia tabaci growth and development were studied in the laboratory at (26 ± 1 ) ℃, (70 ± 5) ％ RH and a photoperiod of L∶ D = 14∶ 10.The results showed that B-biotype B.tabaci liked tomato best of those host plants,and cabbage next.B-biotype B.tabaci could grow and develop normally on those host plants,with its population assuming an obvious upward trend.But there were significant differences in the larva development duration ,survival rate,adult longevity and egg production capacity among host plants.The shortest larva development duration, the largest survival rate, the longest female adult longevity, the highest egg production capacity and the highest intrinsic rate of the population occurred on tomato plants,indicating that tomato was a comparatively suitable for the population growth of B-biotype B.tabaci.
