Abstract
Bhendi is one of the most important vegetable
crops grown in India throughout the year. A number of insect pests severely
limit the output of bhendi. Among the insect pests, the bhendi Shoot and Fruit
Borer, Earias vittella Fab. poses a serious threat and ultimately lowers
both the output's quality and quantity. The first line of defence against
insect pests among the numerous management strategies is the employment of
tolerant and/or resistant genotypes. After taking this into account the goal of
the current study was to evaluate the induction of resistance by agriculturally
beneficial microorganisms in bhendi accessions through feeding and
ovipositional preference test at the Department of Entomology, Faculty of
Agriculture, Annamalai University, Tamil Nadu, India during 2022. In case of
feeding preference, with regard to free choice test, the preference of E.vittella
larvae to the fruit was minimum towards the accessions Salem Local treated with
K-solubilizer and maximum damage recorded in the accession Arka Anamika treated
with Azospirillum. Whereas in confined condition, the accession Salem
Local treated with Azospirillum+ Phosphobacteria + K-solubilizer,
recorded minimum tunneling of fruit by the larvae even after 8 hours, while the
accession Arka Anamika treated with Azospirillum recorded maximum tunnelling.
In terms of ovipositional preference, the accession Salem Local treated with
K-solubilizer produced the minimum number of eggs by the adult moths of E.vittella,
while the accession Arka Anamika treated with Azospirillum produce more
number of eggs in both free choice and no choice tests.
