When you get your garden looking perfect, it can be very frustrating to have your plants and flowers slowly destroyed. Sometimes it can be hard to discover the cause of the destruction, because the pests are very tiny. Thrips could be the cause of your plants’ leaves, buds, flowers, and fruits becoming stippled, dried out, and damaged.
There are many species of thrips that cause problems for gardeners and homeowners across the country. Damage of these pests depends both on the species of thrip and the plant they are feeding on. You may find dried out and stippled leaves that may appear silver-flecked. Infested flower buds may fail to open, flowers may be deformed, and damaged flowers may become streaked and discolored. Thrips can also cause skin irritation if they come in direct contact with skin.
Common Species of Thrips
Populations are at the peak in the spring, and certain species will affect specific plants. Here is a list of common thrips and the plants they affect:
Western flower thrips: These thrips attack hundreds of plant species including oaks, roses, citrus, and vegetables.
Gladiolus thrips: attack gladiola, iris, carnations, lilies, narcissus, freesia, amaryllis, and many others.
Red-banded thrips: In immature stages, these thrips produce a lot of honeydew which can cause premature defoliation in fruit, shade trees, shrubs, and vinces.
Cuban laurel thrips: Mostly attack ficus trees.
Greenhouse Thrips: these are the most common pest of greenhouse and nursery grown plants including maple, azalea, citrus, dogwoods, and magnolia.
