Big Gardens and Big Insects.
Insects love a tasty vegetable meal as much as the rest of us. Large gardens full of broccoli, tomatoes, lettuces, can be buffets for a wide variety of insects. Because we are well into summer and the harvesting season, we will be switching gears with this newsletter and reviewing some common garden pests for the next few weeks. The pest of the week for this newsletter is the Cabbage Aphid.
Correction from last week! We are hosting a Fall Festival at Weaver Creek Park on October 12 from 12pm-4pm. Last week, it was written that the festival was on the 14th, this was incorrect as the festival is schedule for the 12th of October this year. We will indeed have activities and events for people of all ages!
We could use volunteers & community support on the day of the event. If you might be able to help out, please sign up here: https://forms.gle/GE6sDomuVCh27dVp6

Cabbage Aphids
Cabbage Aphids aka Grey Aphids feed upon a huge range of plants in the Brassica family, think Cabbages, Broccoli, Kale – Thick, almost leathery, green leaves are what these aphids feed upon. Other plants like tomatoes and watermelon are not of interest to this specific garden pest.
Cabbage aphids will lay eggs on the underside of leave in the fall and/or overwinter as nymphs and hatch in early spring.
Where?
Possibly your vegetable garden on plants on the plants in the family Brassicaceae.
When?
These aphids reproduce more in cooler weather, but populations can explode in late spring or during fall; development of nymphs will slow down when day time temperatures reach 95°F.
IPM Cabbage Aphid Management
A range of tools exist in the Integrated Pest Management (IPM) toolbelt. The general idea is to use a measured or tailored response as opposed to applying strong insecticides at the first sign of trouble.
Turn-in your plants early in the early fall and/or immediately after harvest, this will help disrupt the life cycle of the aphids.
Pull heavily infested plants, because Cabbage aphids are not very mobile it can be possible to significantly reduce populations by removing plants which are hosting large populations.
Use insecticidal soaps in low concentrations (see information linked below for more information). Note: Insecticidal soaps are those which contain the active ingredient ‘Potassium salts of fatty acids’; standard dish detergents or hand soaps will have little effect and can severely harm your plants.
