A word about "bugs"...

After I wrote about my modest success growing cherry tomatoes here in Central Mexico a number of people mentioned that they have had little or no luck due, on part, to "bugs" or " la plaga" (lah PLAH-ga) as my wife Gina calls them, which means "the plague" in English. I must admit that there can be a problem but it has an easy solution and should not deter anyone from enjoying the delight of a ripe red, sun warmed cherry tomato bursting with flavor. Basically there are two types of bugs that injure these plants. One type is the chewing variety such as the "oruga" (oh- ROO-gah) or "caterpillar" and the other is the sucking variety such as the "pulgón" (puhl-GOHN) or "aphid". The sucking variety belong to the order "Hemitera". The Hemiptera are characterized by a beak called a "rostrum" with which they can pierce the outer covering of a plant and suck out the juice. There is a suborder of the Hemiptera called "Sternorrhyncha" which contains the subfamily "Eriosomatinae" or "Wooly Aphid" and also the subfamily "Aleyrodoidea" which contains the "White Fly". The Wooly Aphid or the White Fly are often what do the most damage to tomatoes and pepper plants.

Both the Wooly Aphid and the White Fly are innocuous looking creatures and most of the time people are unaware that they have an infestation until considerable damage has already been done. That's because these little pests are so tiny as you can see in the photos below. They look like little white specs of fly ash and only when you disturb them and they rise up in a little cloud like a miniature snow storm are you aware that they are even alive. They appear in the garden at this time of year because they like humidity and juicy plants. Fruit bearing plants are their favorites and both tomatoes and peppers are part of the "Solanaceae" or "Nightshade Family" and they are actually classified as fruits. We are between rainy seasons at the moment and the only place you generally find humidity and juicy plants from now until mid-May or early June is in a garden. The little buggers stick their snout into the plant tissue and suck out the juice. Little by little mold forms at the wounds and eventually the infested area of the plant turns yellow and then brown. The plant doesn't die but it becomes very stressed and may not grow very well or bear much fruit as a result. Eventually Lady Bugs and other friendly (to man) predator insects take care of the aphids and the white flies but in the meantime the damage has already been done.

What can be done about it? Well, the first thing you can do is bend over and look at your plants. Yes, bend way down and get to know them. For one thing it is good exercise and for another it is educational. You just might discover a new world. If you do have a pest problem with bugs the next thing to do, of course, is to get rid of them. Actually it is quite easy. A strong stream of water will knock them right off the plants. Keep doing this for a few days and the problem will be greatly reduced. A better method is to spray the plants with a solution of liquid dish soap and water, about a teaspoon per liter of water or so. It won't hurt the plants, especially if you rinse them off later, and you will drive the bugs completely away. Don't be tempted to use harsh chemicals because they are too hard to control. Oh, I keep a can of Raid Max around for zapping those big ugly cockroaches when they get in the house but that's as far as I go with chemicals. Like the beer people say, "Todo con medida"..."Everything in moderation".

Happy Gardening!
