APHIDS in the Greenhouse

Some of the following advice is excerpted from the book "Greenhouse Gardener's Companion" revised edition Copyright 2000- all rights reserved.

Question:
Help I'm having problems with aphids in my greenhouse. I released some green lacewings and they don't seem to be working.

Answer:
It is a good idea to get these guys under control. I have had great luck with biological control using small parasitic wasps which really go after the aphids (as discussed in the revised version of my book). Aphidius colemani and Aphidius ervi are both good at controlling these critters.

Also, I have excellent luck w/ Aphidoletes aphidimyza. This aphid predator is also known as "aphid midge" and works great as a general feeder of aphids. The adults feed on flower nectar and pollen. The adults usually lay eggs near aphid infestations, and larvae hatch out and feed on the aphid for 3 to 6 days before burrowing into the soil to pupate into an adult. It kills the aphid by injecting a paralyzing toxin into the aphid and then sucking out their body fluids. It works best in the warmer months when the days are longer.

Two quality sources for these critters include: IPM Laboratories (1-315-497-2063 and www.ipmlabs.com) and International Technology Services, Inc. (1-303-661-9546) as well as other sources (see above). As far as the green lacewings, I would suspect that you have a bad supplier who shipped you some dead lacewings! Get your money back! Sadly, this happens all the time!

Now some spray options: Sprays that are kind to beneficials insects include: Beauveria bassiana, a fungus-based spray works well on aphids and has a low toxicity rating. Neem oil is also easier on predators and parasites and can help reduce the numbers of aphids when you release some beneficials to help. Be sure to check the neem oil label to be certain that it is safe for use on the crops you're growing.

Other sprays: Soap sprays and horticultural oils work well on aphids but must be used with care as they can also cause burning on sensitive plants. They will also kill any beneficial bugs you might have released if you get direct contact w/ the spray.

Pyrethrins are botanically based and kill both good and bad bugs alike.

Always when you spray follow the directions and spray the underside of the leaves where the critters hide and multiply!
