Repellent action of cashew (Anacardium occidentale L.) nut shell liquid (CNSL) on adult papaya fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae)

The fruit fly, Bactrocera dorsalis is a major pest of papaya and known to cause economic losses to the agricultural industry globally. It attacks the fruits causing premature ripening and rotting. This study aims to investigate the repellency activity of the liquid extract of the cashew nut shell us...
