Aphidius colemani - Aphid Control


Many species of small-bodied Aphids such as Cotton/Melon Aphid, Green Peach Aphid, Black Bean Aphids, Cannabis Aphids, and more.


Aphidius colemani are tiny parasitic wasps measuring around 2-3mm long and have a black body with translucent wings. They are often mistaken for small flies due to their size and delicate appearance. Aphidius colemani is widely distributed and commonly used in biological pest control programs in agriculture and horticulture.

Sex ratio is 60-70% female. Each female can lay more than 300 eggs. The female adult will lay an egg directly into the aphid body where it hatches and the larvae will consume the aphid’s body from within. When A. colemani larvae mature, the host aphid transforms into a black mummy over 7 days. Subsequently, it takes another 14 days for the mummy to mature into an adult, which emerges through a hole at the mummy's rear. Expect to observe the first mummies in your crops at least 14 days after the initial release.


Indoors and outdoors on a wide range of plants in greenhouses, vegetable crops, ornamental crops, soft fruits, tree nurseries, horticulture landscapes, and various other types of crops.


1-2 wasps per square foot every 1-2 weeks.

5-10 wasps per square foot, weekly for at least 3 weeks.

Sprinkle contents onto leaves or into Hanging Release Boxes and hang on infested plants. Do not place mummies directly onto soil or substrate and keep product dry.

It's important to note that these release rates serve as general guidelines and may vary based on the specific pest species, the crop or plant being treated, and level of infestation. Proper monitoring of the infestation and the subsequent effectiveness of the released beneficial insect population is crucial for determining the success of the biological control strategy.


Proper identification of the aphid species is important. Monitoring the crop closely and early releases will help in overcoming the pest. Pesticides and even wetting agents and spreader-stickers may adversely affect beneficial insect survival. Broad spectrum and systemic insecticides are toxic to these insects.

Remove yellow sticky cards for the first few days after release.
