Aphid Parasitic Mini-Wasps (Aphidius colemani)

These are live insects, and in order to increase survival rate during transit, they are required to be shipped Overnight, which adds on an additional $45 to the total.

Aphidius colemani are aphid parasitoids and very useful and effective for the prevention and low-infestation management of various aphid species.

These 2-3 mm. mini-wasps are best used for preventing the establishment of more than 40 species of aphids. They can also tackle light to medium infestations. And, if established, they can adequately protect a crop throughout the season, with some possible exceptions in late summer (see Drawbacks).

Aphidius colemani, which are normally shipped as 500 ready-to-emerge mummies, seem to be the product of choice when melon or cotton aphids (Aphis gossypii) are present as these are typically the aphid species on which they are reared.
