Seminar Description:
Short-spined thrips and aloe thrips are invasive thrips species that our team recently identified as present in California nurseries and landscapes, respectively. Both can cause significant damage to ornamentals and landscape plants. In this seminar, we will cover ID, biology, and host range for both pests, show where they have been found in California, and describe common signs and symptoms of infestations of either thrips species. We will then go over management techniques for both and what you should do if you encounter either of these in the landscape.
Learning Objectives:
1. Identify Thrips parvispinus and its damage on common host plants
2. Identify Hercinothrips dimidiatus and its damage on aloes
3. Understand current management techniques as well as best practices for reporting both pests
