Thrips

12/7/2015

Whether there is one or a hundred and one they're called Thrips. When I was in college my entomologist instructor impressed on the class that its Thrips not  thrip that's the main reason for damaged ficus trees this time of year.  
Thrips are tiny insects that are usually yellow, tan or black. They damage plants by sucking juices from leaves which in turn cause yellow pale spots and leaves will curl. 

In severe infestations, especially  with Ficus nitida - a commonly used street tree, leaves will turn yellow and die.  Thrips thrive in hot dry summer-like conditions.  

Minor thrips infestations can be handled with a strong blast of water and feeding the plants.  Otherwise, you may have to break out the insecticidal soap or a ready-to-use natural control like Captain Jacks Dead Bug Brew.
