Detection of Duponchelia fovealis Zeller with pheromones in strawberry farms of Costa Rica




European pepper moth, population dymanics, pests sampling, sexual pheromones


Introduction. Duponchelia fovealis Z. is a pest of production crops in Europe and in the United States. It has recently been detected in strawberry production in Brazil, Mexico, and in a farm in the Vásquez de Coronado canton, San José, Costa Rica. Objective. To determine the presence and distribution of Duponchelia fovealis Z. in strawberry farms in Costa Rica. Materials and methods. During the dry seasons of 2020-2021 and 2021- 2022, traps baited with the D. fovealis pheromone were placed in the initially reported farm in Vásquez de Coronado and in six other farms located in the main strawberry regions of Costa Rica: La Cima of Dota, Llano Grande, Poás, and Vara Blanca. Results. The monitoring showed that the highest populations were established in the Vásquez de Coronado farm, while occasional captures were obtained in farms such as La Cima of Dota in San José and two in Llano Grande in Cartago. Conclusions. The presence of D. fovealis Z. in Costa Rica was determined, with limited distribution. Given this, an analysis of the risk of the pest and the implementation of measures to reduce the insect’s dispersal are suggested.
