This pack contains one pheromone lure of Bactrocera cucurbitae (Melon Fruit Fly), specially designed for use in fruit fly traps for efficient monitoring and management of fruit fly infestation in cucurbit crops. The lure attracts adult flies into the trap, helping farmers detect pest presence early and take timely control measures to minimize crop damage.
Identification
The eggs are pure white, elliptical, about 2 mm long, slightly curved, and usually laid inside young fruits or tender plant parts. The larva is white, maggot-like, cylindrical, and legless with a tapered front end and flattened rear. It has three larval stages (instars) and may grow up to 7.5–11.8 mm in length. A distinguishing feature is a dark horizontal line near the rear end below the spiracles. The adult fly is about 6–8 mm long, with a yellowish head marked with black spots, reddish-yellow thorax with light markings, and characteristic patterned wings.
Life Cycle
The development from egg to adult takes about 12–28 days in warm conditions, but may extend in cooler weather. Female flies start laying eggs after 7–26 days and can continue for 39–95 days, laying up to 1000 eggs in their lifetime. Eggs are laid in young fruits, tender stems, or soft tissues using a sharp ovipositor. Larvae feed inside fruits and later pupate in the soil at a depth of up to 2 inches. Adult flies can live for several months and feed on plant juices, nectar, and honeydew. There may be 8–10 generations in a year under favorable conditions.
Nature of Damage
The larvae cause severe damage by feeding inside fruits, making tunnels that lead to rotting. Affected fruits show water-soaked patches, become deformed, and often drop prematurely. These tunnels also allow entry of bacteria and fungi, accelerating decay. In addition to fruits, larvae may attack young seedlings, roots, stems, and buds of host plants like cucumber and squash. Heavy infestation significantly reduces yield and market quality, and also affects export potential due to quarantine restrictions.
Target Crops
Watermelon, Muskmelon, Pumpkin, Bottle gourd, Cucumber, Ridge gourd, Bitter gourd (Karela), Tinda, Parwal and other cucurbit crops.
