Help identifying pests

19 years ago

Howdy,

I'm a totally new to gardening, so I don't know what anything is called yet. Because of this I'm having trouble finding information identifying various pests on my plants.

I took pictures :) Click to go to the web album with the large versions.

First, the potatoes. Some kind of bug seems to be sucking on the leaves, causing them to brown at the edges:

Here is the bug I suspect:

Next is a litte beetle I found on both the beans and potatos:

I found this beetle on the beans and peas, not sure if it is a problem, as they are looking pretty good:

This caterpillar is trying to eat the broccoli:

The lettuce is doing very well, but I found these two bugs on them, not sure if they are pests I need to worry about:

Lastly, one of the apple trees is getting particularly heavily spotted. I think these is fairly normal and harmless, but I don't usually see them this dense:

Mostly I'm looking for ID's on these, but suggestions how how to get rid of them in an organic garden would be helpful. For the most part I just squish them, but some of them are darn fast.

Mostly there is no reason to control these since many are beneficial and eat the insect pests you might have. The potato leaf could have one of the blights or that could also be leaf scorch, the leaf transpires moisture faster than the roots can resupply the leaf and this is what happens. Your cabbage worm could be either the Imported Cabbage Worm, or the Cabbage Looper, either one easily controlled by squishing or by judicious applications of Bacillus thuringiensis - Kurstaki.
If you see an insect on a plant with no damage leave it alone unless you know it is a pest since it could well be a beneficial.

2 is the tarnished plant bug, I believe. If you have a lot of them, you'll want to get rid of them. They can cause some problems.

Do not leave the cucumber beetle alone until you see damage. It is a carrier or vector of wilt and by the time you see damage, your cucurbits are diseased and destined to die and you've cut your crop production time in half. That is one pest I scout for and control. It's not the physical damage they do you need to be concerned about, it's the diseases they carry.
