APHIPAR - Parasitic Wasp Aphidius Colemani

*ORDERS FOR BIOLOGICAL PEST CONTROLS MUST BE PLACED BEFORE WEDNESDAYS AT 11:30 AM PST TO BE SHIPPED THE FOLLOWING WEEK*

Adult female parasitic wasps lay their eggs parasitically in the aphids, causing them to swell and harden into leathery, grey/brown mummies. The first adult parasitic wasps emerge through a round hole at the rear of the mummy approximately 2 weeks after introduction. Each bottle contains mummies mixed with wood chips. 

Use Aphipar for the biological pest control of primarily:

• cotton aphid (Aphis gossypii)
• tobacco aphid (Myzus persicae var. nicotianae)
• peach-potato aphid (Myzus persicae var. persicae)

• Aphipar is especially useful at the beginning of aphid infestations.

Application Instructions

• Spread the material on rock wool slabs or in Diboxes
• Make sure the material remains dry and is not moved from its introduction site for at least a few days
• Use the peel-off label to mark where the product has been introduced

• Efficacy reduces at temperatures above 30°C.

What to Expect Upon Arrival

This product arrives as aphid mummies in carrier material, not as visible flying adult wasps. Adult Aphidius colemani emerge from the mummies after placement. Keep the material dry at the release site and avoid disturbing it for the first few days.

Important Notes

We import most biological controls fresh to help ensure customers receive active, viable beneficial insects, mites, and nematodes. Because these are living products with limited shelf life, we do not keep most biologicals stocked in-house.

Please inspect your package and product immediately upon arrival, before release. If you have any concerns about condition or viability, contact us before releasing at admin@optimizeorganics.ca with your order number and clear photos of the package and product. Once beneficials have been released, it becomes much more difficult for us to assess their condition on arrival.

Biological pest control is rarely a one-and-done release. In most active pest situations, sequential releases are needed to build and maintain beneficial populations while pest eggs continue to hatch and existing pest pressure is reduced.

Avoid spraying pesticides, oils, soaps, or other residues immediately before or after release unless compatibility has been confirmed, as these may harm beneficials.
