McPhail Trap

The McPhail Trap is used around the world to monitor fruit flies in area wide monitoring programs, Sterile Insect Technique (SIT) programs, orchards and quarantine areas. It consists of three parts, namely a yellow bottom section, shaped as an inverted funnel, a transparent top which houses the PheroLure® and a plastic water ring. This trap is baited with three kinds of PheroLures, namely the E.G.O.® PheroLure®, 3-Component Lure and a water mixture with Torula Yeast and 10 % Borax.

The McPhail Trap is a plastic trap consisting of three interlocking sections:

  • A clear top
  • An inverted funnel
  • A water ring

Insects, attracted by the PheroLure® that is suspended in the transparent top, enter through the hole of the inverted funnel base. Once inside the insects are trapped. Trying to fly towards the light and escape through the transparent top, the insects fall exhausted to the bottom of the inverted funnel, where the gas of the Dichlorvos block kills them.

After mating with the male the female lays eggs just below the surface of the fruit, which is what we see as the sting. Once the eggs hatch, the larvae of the Fruit Fly, which are small maggots at this stage, feed off the inside of the fruit before exiting and falling to the ground to pupate, after which they become adult fruit flies. The end result is spoilt, rotten fruit which is wasted.
