Tips and Tricks:
Colemani are tiny and dark coloured wasps that do not sting. They are easily seen with the naked eye and can be clearly differentiated from its target pest, the aphid. We recommend marking the aphid hotspots and using a 10-15X lens to look for parasitized aphids (mummies) in those areas. The mummies should appear 2 weeks after the release. Colemani does not attack potato aphid, so if no mummies are found check for aphid identification.
Aphidius Colemani is a parasitic wasp that specifically targets aphids. These wasps seek out aphid colonies by sensing the signals of infested plants as well as detecting the aphid’s honeydew secretions. Parasitization occurs when females lay their eggs inside the aphid. Each female can lay about 200-300 eggs in its lifetime but may attack more aphids in the process. The eggs then hatch into a larva and consume the pest from the inside. Next, it pupates inside the body of the aphid, which hardens into a leathery, golden-brown mummy and emerges as an adult a week later. These parasites are a great choice if you need year-round maintenance of your crops since short winter days do not concern them. Colemani is shipped in a package of 500 pupae (mummified aphid stage) from which adult Colemani emerges. Some adults may have emerged during transit.

Use of pesticide can cause mortality in the Colemani population. They are likely to be sensitive to the same pesticides as Encarsia. Yellow sticky traps are also harmful to Colemani; if they must be used we recommend only placing them at a ratio of 1:100 yellow sticky trap to plants. Insecticidal soap and pirimicarb does not harm Colemani pupal and can be used to control aphid hot spots.

Pesticide and Other Controls:
Colemani prefers a temperature of 20°- 25°C and high humidity of over 60%. It can works very well in cucumber, eggplant, flower, ornamentals, and capsicum crops, as well as field crops such as potato, sweetcorn, cotton. This predator can be used year-round and is not affected by the length of the day. However, it is not active at temperatures below 10°C and above 30°C
Release as soon as possible, preferably in the evening when the temperature is cooler and light is low. Release rate varies considerably depending on the crop, infestation level and season of the year. This is just a general release rate, please contact us here to create an IPM program that works for you.
