Used for controlling cucurbit fruit fly (mainly Bactrocera cucurbitae) in vegetable crops like cucumber, gherkins, squash, melons (water melon, muskmelon), pumpkin, ash gourd, bitter gourd, ribbed gourd, bottle gourd, etc.The development period of this fly, from egg to adult ranges from 12 to 28 days. The female may lay as many as 1,000 eggs. Eggs are generally laid in young fruit but are also laid in the succulent stems of host plants. The eggs are deposited in cavities created by the female using its sharp ovipositor. After eggs hatch into small, white larvae, they eat from their nesting site, absorbing the nutrients and energy needed to transform into adults. Larvae then locate dark, dry places for pupation. During this stage, the legless larvae grow six legs and a pair of wings before emerging as adults.
