Host-associated strains within Ugandan populations of the whitefly Bemisia tabaci (Genn.), (Hom., Aleyrodidae).

摘要: : Studies were undertaken to investigate host relationships of populations Bemisia tabaci taken from the major crop hosts in Uganda. B. adults cotton and sweet potato did not colonize cassava. None survived for longer than two days nymphs emerging eggs laid on cassava died. Cassava contrast showed limited colonization retained ability cassava, confirming genetic basis distinction between ‘strains’ suggested by previous isozyme studies. The implications these findings with regard role epidemiology African mosaic geminivirus are discussed.
