Aphidius colemani

Female is black with bright-brown legs. The abdomen is pointed, about same length as the wings. Male has dark-brown legs, somewhat longer antennae and its abdomen is rounded and shorter than the body. An aphid that is parasitized by Aphidius gets swallowed and changes into a brown mummie. The adult parasitoid hatches from the mummie through a round lid.

Mode of action:

This parasitoid is a very good searcher. Even at low densities aphids will be found and parasitized. The egg laying process is very fast so these parasitoids are not seriously hampered in their egg laying by presence of ants. A rather serious threat for this parasitoid is hyperparasitisation. Especially in summer and early autumn hyperparasitoids start laying eggs in aphids that have before been parasitized by Aphidius. The hyperparasitoid will develop at the expense of the primary parasitoid so population build up of Aphidius will be hampered.


For control of cotton aphid (Aphis gossypii), green peach aphid (Myzus persicae) and oleander aphid (Aphis nerii) in greenhouse cultures and indoor plantscapes. APHIPAR may well be used combined with other products such as APHIDEND or MIRICAL. Scatter the contents of the bottle on infested plants and leave it there for several days. Consider repeated introductions. The product is sensitive for chemicals plant protection products. Ask advice for introduction strategy.

effect of APHIPAR:

  • parasitized aphids swallow into greyish-brown round mummies
  • first mummies appear around 2 weeks after introduction
  • young parasitoids hatch out of the mummie through a round exit hole at the back of the mummie

The product APHIPAR:

mummies in a 100 ml bottle with wood fibres. 1000 adult parasitoids will hatch from the mummies.

Shelf life:
maximum 2 days at 8-10 °C, laying in the dark.

At temperatures above 30°C the effectiveness is not optimal. In summertime the parasitoid may be found outdoors as well.


Targets APHIPAR :

  • cotton aphid
  • green peach aphid
