Garden Pest - Chilli Thrips

A relatively new species of thrips ~ ~ Chilli Thrips Scirtothrips dorsalis Hood ~ ~ that attack a wide variety of plants in Florida are becoming more prevalent. Some of their favorite plants are: Begonia, Citrus, Hydrangeas, Ornamental Sweet Potato Vine, Indian hawthorne, Snow Bush, Azaleas, Camellias, Golden Dew Drop, Verbena, Crape Myrtle, Geranium, Coleus, Variegated Pittosporum, Plumbago, Marigold, Victoria Blue Sage, Viburnum, Roses and many varieties of vegetables to name a few.

Unlike the common thrip, Chilli thrips can be found on the axils of leaves or curled leaves and leaf litter. Affected plants will have brown and/or rolled leaves and distorted flowers. This is a tough insect that can do a lot of damage very quickly.

Infestations are easier to control if you discover them early and treat immediately.  Fortunately, there is a  product called Conserve Naturalyte which contains Spinosad ~ a  naturally occurring soil dwelling bacterium ~ that can be used to control the thrips. Remove all damaged flowers and apply the product only as needed as it can be toxic to bees until it has dried. Otherwise, the product has shown very low toxicity levels to other critters. Natural enemies include lacewings and ladybug beetles.

Good luck in treating infestations should you discover any on your plants or vegetables.
