Managing Thrips as Direct Crop Pests and Vectors of Phytopathogens

Unravelling important aspects of the Thrips parvispinus (Thysanoptera: Thripidae) biology

Location: Phoenix Convention Center, 122 C, PCC
Oral Presentation
Thrips parvispinus was first found in Orange County, Florida, in 2020. This polyphagous pest has been spreading from southeast Asia to Oceania, Europe, Africa, and North America, experiencing great expansion in its geographic distribution over the last 20 years. Injury by this pest is associated with the deformation of young leaves, leaf spots, and holes, affecting photosynthesis and disrupting normal growth. To stop the further spread of this pest, the Florida Department of Agriculture and Consumer Services - Division of Plant Industry (FDACS-DPI) regulates T. parvispinus. Despite its economic importance, little information is available regarding its biology. We will demonstrate significant aspects of T. parvispinus biology, such as its ability to pupate in the soil and its reproductive system. We will discuss the findings under the prism of IPM.
