Monitoring adult carrot weevil activity in Ohio fresh parsley fields

 


Monitoring adult carrot weevil activity can be challenging because these insects are small and cryptic. If it is early in the season (before crops have germinated) you can deploy wooden Boivin traps, baited with a single carrot, on the edges of fields that were infested the previous year. Here’s a link to a helpful fact sheet created in the lab: Monitoring Carrot Weevils Using Wooden Boivin Traps _ Ohioline-v5rgfv. If it’s later in the season and crops have germinated in the field, Boivin traps are not as effective. At this point in the season, you should begin scouting your fields. Rather than scouting for adults, look instead for egg-laying scars on the petioles of young plants. Although this is a tedious task, it is a more reliable method for monitoring adult carrot weevil activity in the field.

 

Investigating the emerging pepper weevil threat in north central Ohio

The pepper weevil has emerged as an unexpected, but recurring pest of field peppers in north central Ohio. This insect is endemic to southern states and unable to survive in northern climates because host plants are not available during winter months. We are working with growers to determine the origin of these unexpected pepper weevil infestations and are evaluating the efficacy of pheromone-baited sticky traps for monitoring these insects in commercial pepper fields.

This effort is an on-going collaboration between Ohio State’s Extension IPM program and the Dept. of Entomology. We are contributing information to a statewide monitoring program, reporting the number and date of first detection of these important insect pests of small fruits.
