Recently, as part of their tHRIve series. the Horticultural Research Institute (HRI) organized a webinar about the Redheaded Flea Beetle. In the presentation, Bryan Kunkel of the University of Delaware explains more about the problems and how to manage it in nurseries.
So what topics have been discussed during the presentation? It briefly covered insect phenology for the mid-Atlantic and how it has provided some guidance with management in the southeast. There also was a discussion regarding larva and adult activity in relation to growing degree days and plant phenological indicators. Host plants fed on by the beetle has been discussed as well, and recent observations in the selection from different species and cultivars of Hydrangea. Also more information has been given on feeding preference trials conducted in the field and laboratory between different species of plants other than hydrangea. In this session they also discussed timing of different management options for the flea beetle larvae and adult stages. Insecticide efficacy trial evaluations have been shared and discussed. Additionally, they discussed the successes, limitations, challenges and potential for biological control and entomopathogens in pest control.

Upcoming Webinars - Plant Benefits or Features: Which Cue is More Effective?
On April 15 (1:00 p.m. Eastern) HRI will host another webinar. "Better understanding consumer behavior, preferences, and trends is a key HRI research priority. In 2020, Dr. Bridget Behe built upon her previous research that showed younger customers were more likely to purchase a branded plant – even when identical to a non-branded plant – and that consumers in general want more information on signs because they cannot ascertain plant attributes by looking at it. In this session, Dr. Behe will review new research findings from her study looking at which benefits resonate best with which type of consumers." Click here to register
