It is that time of year when the nights cool and while we are enjoying it, so are some of the pest bugs. The aphids, mealybugs, leaf miners, horn worms etc. come out. The plants are energized by the cooler day time temps and so are the bugs who want to eat them.
Pictured to the right is an aphid infestation back in March (Spring and Fall are the major invasion times because of the warm days, but cool nights.) I had a similar invasion on one of my pepper plants and treated it with Neem spray. In March I used a hard hosing followed by the home made safe soap spray - recipe below*.
I could just scrape them off, but in this case I notice a LOT of ant activity around them. Ants "shepherd" both mealybugs and aphids, protecting and nurturing them like a ranch raises cattle. It is a little hard to make out the ants, in the low morning light this was the best my camera would do.
Ants are nature's clean up crew in our gardens and sometimes you see them on flowers, collecting some nectar. However, if you see a LOT of ant activity look for aphids or scale/mealybugs and be proactive. You can scrape off scale, but not aphids. I chose to go with a spray. I ran out of my Neem and found an alternative Organic spray which seems to work fine. It is a mixture of essential oils, plus wax and oils.
To adequately control aphids you need to spray every 5 days for a total of 3 times minimum to ensure you take care of adults, hatchlings and eggs that will hatch out
Leafminer damage is generally more cosmetic than severely damaging to a mature plant, but still I don't want to let them get really going. Just pick off the leaves and toss - do not compost.
Deane and view the hornworms differently. He destroys them and I relocate them (this time to the dump trailer where it can have a possible chance to morph into the Sphinx Moth which is a major pollinator of desert cactus).
Limit sprays where you can pick off the bug or in the case of the leafminers the whole leaves. This helps to keep sprays away from possibly hitting the good guy bugs.
Accept some damage in your gardens to "ring the dinner bell for the beneficial insects to show up". If there are no visible pests then the beneficials may not come to your rescue when you really need them.
Also keep something blooming in the garden at all times. The beneficial insects also need nectar.
I collected some interesting links this week to share with you.

Mark Lewis interviewed on podcast - Desert Forager - Mark shares his knowledge learned from his grandfather passed down to him through many generations of native experience. You can find Mark at the Old Town Scottsdale Farmers Market on Saturdays.
My interview by Greg Peterson of Urban Farm. There are several optional links.
IN THIS PODCAST: Catherine shares with Greg some of her tricks that she has figured out for growing herbs in her garden in Phoenix. She explains how she learned about new herbs by asking her farmers market customers about their heritage, and how she experimented to expand her knowledge and skills. She talks about some of her favorites including nasturtium, stevia and Syrian oregano. She teaches Greg how to pick herbs for the best enjoyment and how to make a personal blend.
