What does fruit fly larvae look like? Fruit fly larvae are similar to maggot-like blowfly larvae. They are legless, tapered at the front, and blunt at the back. Before ovipositing, some female larvae may regurgitate bacteria onto fruits. Fruit fly larvae lack legs and have no wings. They have two hooked mouthpieces that allow them to feed by tearing flesh.
The adult fruit fly lays eggs in mature, ripe fruit. These eggs hatch into larvae in two to three days. The larvae develop and pupate within the fruit and eat fungi and yeast. These bugs are attracted by fermented fruits and vegetables because they feed upon the yeasts that cause disease. Infestations of fruits and vegetables are common in the United States.
Adult flies are dark brown to black in color. Female fruit flies lay their eggs in fermenting organic matter. The larvae emerge with a food source right away. Although fruit flies are not capable of biting, they can transmit disease-causing germs to animals and humans. Fruit fly larvae can cause diarrhea and gastrointestinal discomfort if eaten. For more information, contact a pest control professional.
When the adult fruit fly emerges from the pupal case, it burrows towards the surface and inflates its wings. It can mate within a week of its emergence. This insect lives for several weeks, and both the female and male continue to lay eggs. Fruit flies eat rotting fruits and secretions of aphids. During the adult stage, they reach sexual maturity in about a week and can live for 40 to 50 days.
A series of developmental stages is required for fruit fly larvae. At the end of the third larval stage, fully grown fruit fly larvae grow to about 9 mm in length. They burrow approximately five centimeters into the soil under a tree. Then, they develop into a barrel-like pupal case made of their own skin. They can live for several weeks depending on the temperature.
If you have discovered that your fruits and vegetables are infested with fruit flies, your next step is to remove them from your home. You can prevent fruit fly infestations by making sure all fruit and vegetables are airtight and stored properly. Fruit flies can be prevented from breeding in your kitchen by removing any rotten or overripe produce from your fridge. And of course, keep your kitchen trash cans clean and empty regularly. Also, clean up any fruit juice or other fruit items that may have escaped from your kitchen.
To identify a SWD infestation, look for a pink tint on the fruit. The SWD stings are so small that a magnifying glass can help visualize them. Break open a suspect fruit and examine the insides to find white larvae. Spray the fruit to kill any larvae, then remove it as soon as possible. Bag it and throw it away. To control the flies, you can also spray pesticides.
