Seeing Red? Redheaded Flea Beetle

This presentation will briefly cover insect phenology for the mid-Atlantic and how it has provided some guidance with management in the southeast. There will also be discussion regarding larva and adult activity in relation to growing degree days and plant phenological indicators. Host plants fed on by the beetle will be discussed, and recent observations in the selection from different species and cultivars of Hydrangea. You will hear about feeding preference trials conducted in the field and laboratory between different species of plants other than hydrangea. In this session we will discuss timing of different management options for the flea beetle larvae and adult stages. Insecticide efficacy trial evaluations will be shared and discussed. Additionally, we will discuss the successes, limitations, challenges and potential for biological control and entomopathogens in pest control.
