Title: Effects of host plant density on the population dynamics of Bemisia tabaci and its chemical control.
Abstract: Effects of host plants density on the population dynamics of Bemisia tabaci(Gennadius) and its chemical control were studied in 2008 in Shanghai.The results indicated that during growing stage of potato and cucumbe plants,the population of Bemisia tabaci increased continually.The differences between the population density of adult and 4~(th) instar nymphs during the peak of Bemisia tabaci on various planting densities on both potato and cucumber were significant,and the order was low-densitynormal densityhigh-density.The pesticide of Emamectin benzoate and Nitenpyram could effectively control the pest.
