Effect of Wolbachia as biocontrol agent on fecundity and survival of cassava whitefly in northwest Nigeria

Whitefly (Bemisia tabaci Genn.) is known to vectored Cassava mosaic virus (CMV) and brown streak (CBSV), these viruses caused major diseases of cassava in Africa. An experiment was conducted determine the effect Wolbachia as biocontrol agent on fecundity survival whitefly infesting cassava. Whiteflies were captured reared using rearing cages. isolated from infected whiteflies, cultured used for inoculations. The under control conditions glass Results this research revealed that number eggs lay by Bemisia inoculated with significantly (P = 0.05) reduced weeks after inoculation which differ among genotypes. Number B. free higher (964.35) than those (46.541) at 4 (4WAI). genotype ‘Dan Aliero’ had highest (4WAI 82.33), while, ‘Farin rogo’ lowest 23.33). nymphs adults also when Wolbachia. 59.00) 51.00), respectively. recorded (17.67) (13.00) 4WAI, For first time, evaluated whiteflies management. From finding study, can be suppress infestation other vegetable crops.
