A farmer friend complained about his ampalaya prematurely ripening on the vine and of small holes appearing on the fruit. Other farmers were quick to point out that these were indications of a fruit fly infestation.
“The yellowing means the files have gotten to it already,” Raphael Dacones of Teraoka Family Farm says.”You can check if there’s a hole. If there is, it means it’s been fed on already.”
Fruit flies (Drosophila melanogaster) can be a pest for farmers. The flies love off rotting and fermenting produce, laying their eggs near their food sources so the resulting maggots can feed on them after. Aside from ampalaya, they also like to feed on tomatoes, squash, and the like.
Cleanliness is essential in preventing fruit fly infestations. In a garden, covering crops that tend to attract these pests with paper can be enough of a deterrent.
“Raf is right. Ampalaya is a target for fruit flies. Use methyl eugenol or Supernet,” says Julius Barcelona of Harbest Agribusiness Corp.
Natural farmers can also dilute Perla brand or other coconut-based soap in water and use the mixture to liberally “wash” affected plants for two weeks, making sure to cover all surfaces where insects might nest, including underneath leaves. The soap leaves a coating that’s non-toxic to humans but lethal to insects. That brand of soap is made from 50% coconut oil and has a cult following among gardeners for its insecticidal properties. Neem oil and other natural insect repellents can also be applied.
If you think that you’ve already got an infestation on your hands, you’ll have to get rid of all affected fruit to make sure no eggs or larvae are left. “Perla might work but not if the worms are inside. Burn or bury the damaged fruits as they will be the new home base of the pest to attack your other fruits,” Barcelona adds.
Keeping your garden clean is important to keeping pests at bay, as this lessens their chances of breeding in the area. Pests are just one of the challenges a farmer may encounter but with proper prevention and should an infestation occur, rigorous eradication, you’ll be able to enjoy your harvests without having to share them with creepy crawlies.
