Bactrocera cucurbitae

(Melon fruit fly) -This melon fly remains active throughout the year on one or the other host. During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. During the hot and dry season, the flies take shelter under humid and shady places and feed on honeydew of aphids infesting the fruit trees. It is reported the survival of adults for a year at room temperature if fed on fruit juices. In general, its life cycle lasts from 21 to 179 days. There are 8 to 10 generations in a year. The egg incubation period has been reported to be 1.0 to 5.1 days depends on the cucurbits. The larval period lasts for 3 to 21 days, depending on temperature and the host. The full-grown larvae come out of the fruit by making one or two exit holes for pupation in the soil.
Host plants
Melon fruit fly infests over 70 host plants, amongst which, fruits of Bitter gourd, Muskmelon, Snap melon and Snake gourd, pawpaw, Gherkin, are the most preferred hosts.
Damage
For cucurbits, the melon fruit fly damage is the major limiting factor in obtaining good quality fruits and high yield. It prefers young, green, and tender fruits for egg laying. The females lay the eggs 2 to 4 mm deep in the fruit pulp, and the maggots feed inside the developing fruits. At times, the eggs are also laid in the corolla of the flower, and the maggots feed on the flowers. The fruits attacked in early stages fail to develop properly, and drop or rot on the plant.
The females prefer to lay the eggs in soft tender fruit tissues by piercing them with the ovipositor. A watery fluid oozes from the puncture, which becomes slightly concave with seepage of fluid, and transforms into a brown resinous deposit. The eggs are laid into unopened flowers, and the larvae successfully develop in the taproots, stems, and leaf stalks. After egg hatching, the maggots bore into the pulp tissue and make the feeding galleries. The fruit subsequently rots or becomes distorted. Young larvae leave the necrotic region and move to healthy tissue, where they often introduce various pathogens and hasten fruit decomposition. The extent of losses varies between 30 to 100%, depending on the cucurbit species and the season.
ETL for Bactrocera Cucurbitae is 10 No’s of per trap per day.
Use 8 No’s Catch-a-flyTM Traps per acre at 1 week before flowering starts for effective control.
Trap canopy should be placed one feet above crop canopy to achieve optimum catch.
Recommended trap model: Catch-A-Fly™ Fruit fly trap.
Recommended for: Ridge gourd, Ivy gourd, Bitter gourd, Snake Gourd, Musk Melon, water melon, Snap Melon, Pawpaw, Gherkin, Cucumber, Tomato…etc.,
