In a Nutshell

    Fruit fly larvae feed on the fruit's internal tissues, causing lesions and decayExit holes on the exterior of the coat are characteristicMatured mangos may discolor, secrete fruit juice and show a gummy consistence

Symptoms

The symptoms for C. cosyra infection are exclusively visible on the fruits. The females inject their eggs predominantly into matured mangos. The affected fruits exhibit a gummy consistence due to the internal feeding and the digesting process of the larvae. The exit holes of the larvae are visible on the surface of the fruit. Inner decomposition results in brown and sometimes black lesions on the peel. The peel may also be scabbed or pitted. The fruits may discolor and show stains of mold as they progressively decay. They subsequently feature a foul odor and may secrete a mixture of fungal and fruit ooze.

Trigger

The symptoms are caused by the larvae of the fruit fly Ceratitis cosyra. Adults have a yellowish body with black spots scattered on the thorax. Their wings are yellow and may reach a span of 4-6 mm. Females implant eggs into the ripening mango fruits and continue to do so for about two weeks. After 2-3 days, the larvae hatch and start digging tunnels through the mango flesh. Fruits may be infested with up to 50 larva each and can sometimes start to show symptoms only after harvest. To pupate, the larvae let themselves fall onto the ground and dig into the upper layers of the soil. After 9 to 12 days the fully grown flies hatch.

Biological Control

Traps containing protein baits can be effective for the monitoring and catching of C. cosyra populations. The fungus Metarhizium anisopliae parasitizes the pupae of C. cosyra on the ground and can be dispersed by hand or as oil-based spray. Post-harvest hot water treatment of the fruits at temperatures above 46 degrees or prolonged storage at 7.5 degrees or below also destroy the larvae.

Chemical Control

Traps containing an insecticide (e.g. malathion or deltamethrin) combined with a specific bait (protein hydrolysate or protein autolysate) are recommended. This method ensures punctual treatment of the flies, attracting all surrounding individuals. Males of C. cosyra can be attracted and trapped with terpineol acetate or methyl eugenol.

Preventive Measures

    Plant early-maturing varieties to make sure the fruits ripen when fly populations are lowPick infested or dropped fruits every dayInstall protein bait traps to monitor possible fly invasionsDo not grow alternative host plants such as citrus, guava, papaya, melons, etc nearbyWeed and till carefully around the trees to detect fallen fruits under residuesPreferably grow mango varieties with similar growth cyclesTransport and sell unaffected mangos onlyEnsure immediate consumption or proper destruction of unsold fruitTilling around the trees kills the ground-developing pupae
