5P420 – Aphidius Aphidius ervi
Aphidius is a small wasp (1/8″) and is known to be very efficient in the biological control of aphids. Aphidius hunts for individual aphids throughout the crop.
The wasp pierces the back of the aphid with its ovipositor, leaving a small, barely visible reddish mark. They lay an egg in the aphid which, upon hatching, feeds without apparently affecting the victim for a time. From within the pest, the beneficial larva will glue the aphid to the leaf, and spin a cocoon from which it pupates. At this stage, parasitized aphids can easily be recognized as swollen, papery, and a silvery brown colored – also called a mummy. When the wasp is mature, it will cut a circular hole in the skin of the now dead aphid, and emerge as a winged adult
Aphidius is supplied as a pupae inside aphid cases. normally, some will have already hatched, when received. Because of it’s excellent search and detection capacity, small pockets and individual aphids can be easily found and destroyed, often before the grower sees any problem.
