Check Pheromone Traps - Twice Weekly!
Monitoring for pests and diseases is a fundamental first step in creating a proper IPM program. Targeting pests at the right time with the right product can save money, make pest management programs more effective, and can help preserve beneficial insects and mites on the farm. There are many ways to monitor for insect pests, and one very popular method involves the use of pheromone traps.
The numbers you record from pheromone traps can tell you when a particular pest is present in the adult form in your area (useful to determine a "BIOFIX" or simply presence / absence of the pest) and/or to generate information on population trends, including peak activity. In either case, this information can help you determine the best timing for applying necessary control measures.
However, the information that you obtain is only as good as the deployment and servicing of traps. Proper use of pheromone traps includes careful storage and handling of lures, consideration of field placement, replacement of traps and lures as required, and consistent monitoring of traps. In summary:
It's the last point which we'd like to focus on today. Whether you're monitoring for insect pests in the orchard, vineyard, berry or vegetable crops, pheromone traps should be checked twice weekly and on the same days each time. Checking traps once a week during the pest activity period is NOT often enough, because you will not get a good approximation of peak flights and/or upswings in the adult (breeding) population. Things can happen very quickly in the field. With many of the new, reduced-risk insecticides, timing of application can be even more critical.
