Aphidius colemani in Bottles

Aphidius colemani, provided in treatment bottles, is an exceptional solution for managing aphid infestations naturally and sustainably. This specialized parasitoid wasp targets over 40 species of small-bodied aphids, including Black Bean Aphids, Peach Aphids, Lettuce Aphids, and Green Apple Aphids. Nimble and highly efficient, A. colemani actively hunts aphid colonies, injecting its eggs into hosts and initiating a self-sustaining cycle of pest control.

Once released, female A. colemani parasitoids begin seeking out aphid populations. Eggs are laid directly into aphid hosts, where they hatch in 3–5 days. The larvae feed on the aphid from within for 5–10 days, eventually transforming it into a hardened “mummy.” From these mummies, a new generation of parasitoids emerges, continuing the pest suppression cycle. With their 2-week lifespan, each female can lay over 100 eggs, ensuring robust coverage and long-term aphid control.

A. colemani thrives in temperatures ranging from 50–86°F, making it suitable for vegetable, fruit, and ornamental crops in greenhouses, gardens, and open fields. Visible results typically appear within 7–10 days of release as aphid populations decline, and the parasitoids establish themselves as an ongoing line of defense.


Why Choose Bottles?

  • Target Pests: Over 40 aphid species, including Cotton Aphids, Pea Aphids, Honeysuckle Aphids, and more.
  • Specialized Predator: Highly effective against small-bodied aphids, minimizing crop damage.
  • Reproductive Efficiency: Each female lays over 100 eggs during her lifespan, supporting a self-sustaining pest control system.
  • Sustainable Solution: Reduces the need for chemical pesticides by providing long-term aphid management.

How They Work

  • Lifecycle:
    • Females inject eggs into aphid hosts, which hatch in 3–5 days.
    • Larvae consume the aphid from within, transforming it into a “mummy” over 5–10 days.
    • Adult parasitoids emerge to seek out new aphid hosts, ensuring thorough coverage in treated areas.
  • Rapid Results: Visible decline in aphid populations within 7–10 days of release.

How to Decide How Many You Need

  • Standard Application: Release 1–5 insects per 10 sq. ft. weekly for 2–3 weeks.
  • Larger Areas: Adjust release rates based on infestation severity and crop size.

Pro Tips for Success

  • Combine for Comprehensive Control: Use A. colemani alongside other aphid predators like Aphidoletes aphidimyza or ladybugs for multi-layered management of diverse aphid species.
  • Monitor Early: Release parasitoids at the first sign of aphids to prevent population growth.
  • Avoid Pesticides: Ensure plants are pesticide-free before release, as residues can harm beneficial insects.

Storage and Shipping

  • Storage: For best results, release parasitoids immediately upon arrival. If necessary, keep pupae at 39–46°F for up to 48 hours.
  • Shipping: All Aphidius colemani bottles are shipped overnight to ensure live delivery.
