Description

Exterior

Aphidius colemani is a tiny parasitic wasp (about 2 mm), that stings its aphid victim. The body is black with brown legs, long antennae, and veined wings. The female has an oblong abdomen, while the male has a circular one.


Life span

Афидиус колемани препарат против тли
The female deposit its egg in the aphid, where it passes through 4 larval instars. As soon as the larvae development has been completed, the larva rotates inside the pest cuticle, causing it to swell.

Larva

A. colemani eggs hatch into larvae which feed on the contents from the inside. In the beginning, the larva doesn’t kill the host and allows the aphids to grow to the desired size. After 6 to 7 days, the larva grows significantly and consumes aphid.

Mummies

The larvae after 7th days infestation (at 21°C), fixates the aphid on the leaf and forms a cocoon inside the body. On the outside the aphid becomes golden-brown color, this instar is called the mummy.

Adults

After 4th day of mummification, the adult leaves the mummy through a hole. The total life cycle takes 14 days at 21°C and 10 days at 25°C.

During lifecycle, the female lays about 100 eggs. Life span is 2-3 weeks. The ratio of females to males is approximately 2: 1

Technology

There are some strategies of A. colemani applying.
The preventive strategy is based on the planned release during natural spring-mass aphid migration. Blisters are useful for this purpose. They should be placed all over the area in places protected against direct sunlight.
The local strategy is based on applying to aphid outbreaks. In general, for this purpose vials with parasitoids are used. If a first aphid outbreak is found in the greenhouse, the supply of parasitoids should be planned as soon as possible for 1 to 3 individuals per 1 m2 of the total greenhouse area, 60% of the biomaterial should be placed in the outbreaks, 40% around them. Applications are carried out weekly until pest control is achieved. In the case of intensively developing aphid colonies, in individual situations, compatible chemistry should be used which would slow down the aphid development and do not harm the parasitoids. Our technologists are always ready to help in the selection of the most effective protection strategy.
To achieve a stable result we recommend using A. colemani in combination with other bioagents such as: Aphidius ervi, Chrysoperla carnea, Aphidoletes aphidimyza.
