Gardeners often focus on the damaging pests that attack and kill tomatoes. Understandably so, as they can destroy not just tomatoes, but your entire garden.
However, not all bugs are bad.
There are beneficial insects that will eat or destroy the pests you’re trying to get rid of, resulting in happy, healthy tomatoes. Don’t panic when you see these eight bugs on your tomato plants, they are trying to help you out.
1. Minute Pirate Bug
Minute pirate bugs, also known as flower bugs, are tiny predatory insects. These little critters are very tiny indeed. Adults are only one-fifth of an inch long. But you can spot them easily due to their deep purple or black color and white wingtips.
Minute pirate bugs prey on aphids, thrips, and spider mites. Studies suggest flower bugs can consume as many as thirty spider mites each day. All these pests have the potential to be extremely harmful to tomato plants. Don’t get too close to pirate bugs though (even if it is to say thank you) as they are known to bite humans too.
2. Trichogramma wasp
These wasps are completely harmless, typically feeding on pollen and nectar. However, the young wasps are the most beneficial insects to have in your garden, as they stop pests before any damage occurs.
Trichogramma wasps are parasites that attack the eggs of moths and worms. They are extremely useful in the war against tomato hornworms, cutworms, and a variety of other pests that negatively affect tomato plants.
Female wasps lay their eggs inside the eggs of the various caterpillar species. Once hatched, the baby Trichogramma wasp feeds on the nutrients in the host egg. These garden friends have the potential to eliminate these bad pests from your garden.
3. Paper wasps
Much like Trichogramma wasps, paper wasps are efficient beneficial insects. Their name comes from their paper-like hives. They are known to sting humans but aren’t particularly aggressive insects when left alone.
There are several species of paper wasp. They are usually slender, with yellow markings and black wings.
They do a wonderful job of ridding tomatoes of various pests, most importantly, the dreaded hornworm. Female paper wasps lay their eggs inside hornworm hosts. When the eggs hatch, they become parasites, ultimately killing the pest.
Not only are wasps beneficial in pest control, but they aid in the general health and success of your garden. Like bees, wasps aid in pollination. Nectar attracts wasps, which carry pollen on their bodies to and from flowering plants.
Spiders are useful pest predators, keeping back grasshoppers, whiteflies, and aphids, depending on the species. Some may use their webs to trap prey; others actively hunt.
Spiders do absolutely no damage to tomato plants. In fact, they are vital for overall garden health, feeding on many of the pests that are known to cause havoc in gardens.
As gardeners are aware, while they are important in the garden, it is still important to stay away from them while gardening. Several species are very dangerous to humans, including the black widow and recluse spiders.
Despite their pretty colors, ladybugs (or lady beetles) are indeed predatory insects. They primarily prey on aphids, mites, whiteflies, and mealybugs. They aid in population control, and eventually the complete removal of these pests.
Though they are beneficial, ladybugs are the most effective once they’ve established a colony in your garden.
Planting flowers such as marigolds and roses will attract ladybugs, and refraining from using insecticides and watering well will convince them to stay.
You can even buy ladybugs on the internet and release them into your garden. But you might want to learn how to get them to stick around before you do that.
