Dangerous disease from "Drosophila" if allowed to fly to the eyes and food


Get to know “Drosophila”

Mrs. Nipa Benjapong, Medical Scientist 8W., Insect Museum and Taxonomy Department. The Public Health Science Research Institute provides information that Drosophila is a small insect approximately 3-4 mm long. It is usually yellow in color and has red eyes. It is an insect of no medical importance. But it may be economically important. Because it is often found on various rotting vegetables and fruits. Fruit kept in our homes may always be infested by this insect. Caterpillars often live in spoiled fruit, where fungus occurs.


Where are the flies?

The Food Sanitation Division, Department of Health, Bangkok,  stated. That Drosophila is a commonly seen disease vector. Especially around garbage piles, sources of food scraps, fruit peels, rotting fruit, rotting vegetables, and fruit juice fermentation tanks. Wine fermentation tank Vinegar plant, fermented food, aphids, sap. Comes out of wounds on plant stems and may also be found in mountain forests along various roads and in houses as well


Dangerous disease from flies

This is because flies breed in garbage sources, pickled vegetables, rotting fruits, mold, sewage, animal droppings, and hairy bodies and legs that cause various germs such as 

  • Typhoid dysentery has a chance of being transmitted by flies that swarm on food. Contamination of various germs in human food causes gastrointestinal diseases to be transmitted to humans. 
  • Red Eyes Drosophila are small insects that have a habit of flying in groups. Swarming in moist places, such as people’s eyes, can spread conjunctivitis.
  • Pig Mouth Sores: Drosophila can also be a carrier of pig mouth sores.


How to control and get rid of flies

  • Improving environmental sanitation
  1. Throw away food scraps, vegetable scraps, fruit, and various garbage in trash cans with closed lids. Does not leak or seep water and carries.
  2. Get rid of animal manure and waste by burying, composting, and composting in biogas fermentation tanks.
  3. Vegetables, fruits, and pickles should be stored in containers. Food storage cabinets, or with fine cheesecloth lids. Don’t let flies swarm.
  4. Areas of cooking establishments, kitchens, restaurants. Restaurants should be lined with wire mesh screens. Prevent flies from disturbing or swarming with food.
  • Destruction of Drosophila larvae
  • Dry the animal droppings in the sun to destroy the eggs/maggots of the Drosophila.
  • Use chemicals to kill flies according to label instructions, such as pyrethrin, diazimon, chlorpyrifos, malathion.
  • Destruction of adult flies

Mechanical method: Use jackfruit rubber or insect glue on a rope and hang it over the rotting fruit. To catch flies

chemical method

– Use chemicals that are less dangerous to humans, such as pyrethrin 0.1-0.4%, sprayed in buildings.

– Use chemicals to spray breeding areas outside of houses, such as

  • Malathion 2-5%
  • Diazinon 0.5-1%
  • Fenetrothion 0.5-1%
  • Ronnel 1%
  • Use fermented products such as pickled mango, pickled pak choi or pineapple mixed with Proproxur 0.1-2% mixed with bait to lure flies.
