Population dynamics of whitefly (Bemisia tabaci Genn.) in chilli and screening of genotypes against chilli leaf curl virus

Gayatri Kumari Padhi, Labani Maity, Arup Chattopadhyay and Arunava Samanta

The present investigation was carried out to study the seasonal incidence of whitefly in Chilli and its correlation with different weather parameters alongside, fifteen genotypes were subjected for screening against Chilli Leaf Curl Virus. The incidence of whitefly was started from the 45th standard week of (observations-2.07 adults/three leaves) (Fig no.1),and reached its peak in the 48th standard week of observations (7.07adult/three leaves) and again declined subsequently upto 1st standard week of observations with a population of 1.80 adult/three leaves. Then gradually, its incidence reached the peak again in 4th and 5th standard week of observations (6.40 adults/three leaves) and gradually declined. The incidence of whitefly was found to be significantly negatively correlated with maximum temperature (rTemp max=-0.179*) and only negatively correlated with minimum temperature (rTemp min=-0.062) while negatively correlated with with rainfall and sunshine hours with rRF=-0.253* and rSS=-0.281 respectively. Genotypes namely 13/CHVar-1 and 13/CHVar-2 were found to show resistance to CLCV (Chilli Leaf Curl Virus) in field conditions.
