AN EXTENSIVE SURVEY OF BEMISIA TABACI (HOMOPTERA: ALEYRODIDAE) IN AGRICULTURAL ECOSYSTEMS IN FLORIDA

Abstract

An extensive survey of B. tabaci populations in 15 economically important crops and 8 weed species in Florida was carried out from March 2000 through May 2001. Sex ratios did not significantly differ among host plants. Biotype analysis by RADP/PCR indicated the presence of only the B biotype of B. tabaci in all collections. These data suggest that in Florida the B biotype of B. tabaci has excluded the native non-B biotypes in agricultural ecosystems.\n\nMention of a trademark or proprietary product does not constitute a guarantee or warranty of the product by the U.S. Department of Agriculture and does not imply its approval to the exclusion of other products that may also be suitable.
