Trapping Helps Farmers Manage Pests During Unusual Weather Conditions

By Andi Anderson

Unusual weather conditions can make pest management difficult for farmers, especially in fruit production. Changes in temperature and rainfall often affect how and when pests become active. Because of this, experts recommend using traps and field observations instead of depending only on fixed calendar schedules.

Pheromone traps are an important tool used by farmers to monitor pests such as codling moth and other orchard insects. These traps help track pest movement and activity levels. By checking traps regularly, farmers can understand when pests start appearing in large numbers. This information is used to set a “biofix,” which marks the beginning of pest activity and helps in predicting future stages using degree-day models.

However, weather variations can make predictions less accurate. Cool temperatures, especially at night, may delay pest activity even if crop growth continues normally. This can lead to a mismatch between plant stages and pest development. For example, pests may appear later than expected, even after key crop stages like flowering have passed.

This mismatch can cause problems in pest control. Farmers often apply treatments based on predicted timings, but if pests are not active at that time, the treatment may not be effective. On the other hand, applying treatments too late may allow pests to damage crops. Using traps allows farmers to make better decisions by observing real conditions in their fields.

Frequent trap checking is very important. In some cases, advanced tools like camera traps can help monitor pests more closely and detect early signs of activity. This helps farmers apply treatments at the right time and improve crop protection.

Studies have shown that estimated pest activity dates from weather models may not always match actual field data. This difference highlights the need for regular field monitoring along with using models as a guide.

In conclusion, farmers should not rely only on calendar dates or general predictions. Direct observation through trapping and scouting provides more accurate information. This approach helps improve pest management, ensures better crop yields, and supports successful farming even during changing weather conditions.
