ABSTRACT
Laboratory experiments were conducted at Department of Agril. Entomology, Junagadh Agriculture University, Junagadh Gujarat, to study the behavioural response of okra shoot and fruit borer Earias vittella (Fab.) to Btk. Results revealed that, the Btk @ 1 to 4 g per litre had no any adverse effect on feeding of E. vittella larvae as well as oviposition. Therefore, Btk with 1-4g/l can be used for the control of this pests. The higher doses of Btk could not be recommended because, it affects the larval feeding and simultaneously expensive also.
Key words :
Abelmoschus esculentus, Bacillus thuringiensis, behavioural response, biopesticide, Earias vittella, okra.
