Abstract
Bracon hebetor say
is important biocontrol agent of the larval stage of many pests of economic
importance. Present study was carried out to evaluate the efficacy of B.
hebetor as a biological control agent against okra fruit and shoot borer,
Earias vittella. Efficacy of augmentative release of B. hebetor as
biological control of E. vittella in field was evaluated during the
period from February to June 2021. Total number of parasitized larvae of E. vittella
by B. hebetor were recorded at 1, 5, 10 and 15 days after release (DAR).
A 74.8 % maximum field parasitization percentage of B. hebetor to E. vittella
larvae was recorded at 5 Days after release (DAR) followed by 10 DAR and 15
DAR. The study revealed that, B. hebetor parasitizes about74.8% under
field conditions. The augmentative release was effective and larval mortality
was increased.
