The efficiency of cassava brown streak virus (CBSV) transmission by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) and spiraling whitefly (Aleurodicus dispersus) Russell (Hom, was determined. utilized field collected adult populations fed on (allowed 48 h acquisition access feeding period (AAP)) CBSD (cassava disease) symptomatic leaves before transfer onto clean recipient plants. In subsequent experiments, numbers each species were varied per plant to determine the effect rate CBSV transmission. transmitted B. allowed AAP infected at a higher 40.7% compared that A. dispersus 25.9%. This work reports for first time dispersus. A likely biological property reported here is its ability be two belonging different genera (Bemisia Aleurodicus). Management therefore needs focus control reduce chances rates infection disease spread.

Key words: Aleurodicus dispersus, tabaci, CBSD, whitefly, efficiency.
