A Fruitful Fly Discovery

Even the smallest of players have tales worth telling within the intricate dances of nature. Enter the Fruit fly, Drosophila spp. (roughly meaning “love moisture”), a miniature entomological marvel with a penchant for fermentation and a story woven deep into the fabric of daily living.

As the Fruit fly free ranges, this outwardly insignificant insect carries secrets of biology, behavior, and perhaps even solutions to challenges many face. Let’s unravel a few mysteries of Fruit fly, from its vibrant eyes to the potential threats it poses, and the pest control solutions at our disposal.

What is a Fruit fly?

Background:

  • The Fruit fly has been a part of human history for centuries
  • Associated with fermentation sources
  • Although a pesky fly species, the study of Fruit flies has brought numerous beneficial research discoveries in genetics and biology
Understanding their ecosystem:
  • In nature, saprophage Fruit flies play a crucial role in decomposing organic matter
  • Fruit flies become pests when they damage crops and invade human environments
Appearance:
  • Adult length about 1/8 inch
  • Distinctive reddish-brown eyes
  • Bristles or hairs on the tan thorax
  • Narrow blackish bands on the abdomen
Biology and Behavior:
  • Adult Fruit flies are attracted to fermenting organic matter
  • Yeast cells express acetate compounds to attract Fruit flies for cell translocation and colonizations
  • Adult female Fruit flies can lay up to 500 eggs/lifetime in and on fermenting materials as well as fermenting points in and on containers
  • Fruit flies free range flight near abundant food and reproductive resources
  • Erratic flight patterns help to evade predators
Health concerns:
  • Fruit flies effectively transfer pathogens from unsanitary areas to food
  • Contamination can result in food borne illness
  • From a fermenting bolus to your beer!

How long do Fruit flies live?

  • Under favorable conditions, the developmental time of egg to adult is 8 to 10 days
  • Adult Fruit flies can live 1 to 2 weeks
  • Significant reproductive capacity

Do Fruit flies bite?

  • Fruit flies lack mouthparts capable of inflicting bites
  • Mouthparts are structured for sponging up nutrients from fermenting food
  • Persistent adult fly presence is highly annoying

Where do Fruit flies come from?

  • Fermenting food (resource sites) include fermenting rotting produce, liquids, sugary syrups, and even effluence
  • Adult fly-spotting on surfaces results in light-colored spots (saliva) and dark-colored spots (feces)

How to catch Fruit flies?

How to kill Fruit flies?

  • Fruit flies demonstrate attraction to UVA light
  • Utilize numerous fluorescent UVA light traps or new LED technology UVA light traps

How to get rid of Fruit flies?

To control Fruit flies, fermenting foods (reproductive sources) must be eliminated. More obvious sources include garbage and residues inside containers, fermenting produce, food spills containing dairy products and bread, and fermenting liquids (wine, sake, beer, mead, cider, vinegar, etc.). Additional sources include floor mop heads and buckets, soiled linen and uniform storage, floor mats, floor drains, cracks in floors, failing baseboards; behind which, floor cleaning has translocated fermenting wastes.

  • Store produce in coolers to reduce perishability
  • Properly rotate food and beverages–first-in, first-out (FIFO), last-in, first-out (LIFO) and first-to-expire-first-out (FEFO)
  • Ensure that trash containers are sealed and kept clean
  • Dispose of heavy-wet garbage within puncture and tear resistant 6 mil trash bags
  • Conduct routine camera inspections of floor drains
  • Routinely clean floors, floor mats, mop buckets, and mop heads
  • Routinely clean floor drains
  • Repair plumbing leaks, cracks in flooring, and separations in baseboards and wallcoverings
  • Routinely launder table linens and uniforms or use a linen service
  • Install walk-by-monitoring devices to detect low-level Fruit fly activity
  • Install numerous light traps for both monitoring and reducing populations
  • While eliminating fermenting resources, overwhelming Fruit fly populations can be drastically reduced by installing numerous Electronic Fly Killers (EFKs), which can capture large numbers of flies
