Insecticidal Resistance of Okra Fruit Borer (Earias vittella) and its Management

Insect pest is one of the major Earias vittella is one of the important pest of okra and its management is also difficult for its insecticidal resistance mechanism though few chemical and bioagent are effective against fruit borer. Insecticidal like quinalphos, monocrotophos, fenvalerate, deltamethrin, Flubendiamide etc. are effective to manage this insect. Combination of these insecticides is also effective and also able to overcome Insecticidal resistance mechanism. Few biological agent like Trichogram machllonis, T. brasiliensis etc. also identified as an effective control measure against this pest. But Insecticidal resistance is a bottleneck for its management. Many resistance mechanisms like metabolic resistance, non-metabolic, GST, EST etc. play an important role for its resistance behaviour. However many technique like log dose probit (hlp) assays, dry film technique etc. are being used to identify Insecticidal resistance in Earias vittella.
