Damages

The Khapra beetle (Trogoderma granarium) prefers to attack cereals (wheat and barley, but also rice, corn, oats etc.), although it can be found less frequently on legumes (beans, peas, lentils, for example). It always lays on the surface of the stored grain, without penetrating the deepest layers.

Detection and monitoring

1 to 3 traps should be used for every room in the warehouse and must also be placed at least 5 metres apart from each other. The traps must remain active all year round in warehouses with products.


Necessary material

The males of this species are captured for the purpose of reducing mating, so that the unfertilised females will lay unviable eggs. In this way, the pest population is reduced.

For mass trapping the number is increased to 4 traps for every 100m² of warehouse, separated at least 5 metres apart.


Material necesario

The following trap and pheromone can be used ECONEX YELLOW CHROMATIC 40x25 1 UNIT PACK and pheromone diffuser ECONEX TROGODERMA GRANARIUM with 40 days’ duration.

ECONEX LEARNING CENTER

ECONEX puts at your disposal the first open knowledge center that brings together everything necessary to implement pest biocontrol in your crops. We have developed different types of resources to share with you the knowledge we have acquired during our more than 40 years of experience. Each of them is designed to respond, in the best possible way, to different questions related to pheromones, attractants, repellents and insect traps.
