The striped cucumber beetle (SCB) is the main insect pest in cucurbits. Besides inflicting damage on seedlings, it can also transmit bacterial wilt. This project aims to develop mass trapping strategies to keep damage caused by SCB populations below the economic threshold, while minimizing the capture of pollinators and natural enemies. The first step will be to confirm the best trap (attractiveness and type of opening) in order to maximize catches. The second stage will involve mass trapping in and out of season (before planting, then from harvest time to mid-November). Depending on the results obtained, off-season trapping could be included as part of a mass trapping strategy. At the end of the project, a new SCB control method will be made available to all cucurbit growers, and especially organic growers who have few tools available to control the SCB.
From 2019 to 2022
Pest, weed, and disease control, Organic farming
As a result of this work, organic farmers will have more effective tools available to control the striped cucumber beetle.

Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.

This project will provide a better understanding of interactions between a vegetable polyculture system and hedges composed of shrubs and perennials in order to enhance the impact of beneficial insects on vegetable crops.
