| Abstract | ||
| Pest bird damage in agriculture is a significant and long-standing problem globally especially for high value field crops such as wheat, rice and corn. The present study aims to control the pest birds in the field crops by using sonic waves. The study treatments were sonic waves frequency under four levels of 1, 3, 5, and 7 kHz; exposure time intervals of 1, 5, and 1 0 minutes; field measuring distances of 0, 30 and 50 m and the daily measuring period sunshine and sunset. The obtained results revealed that the sound pressure level (dBA) of sonic waves repeller was negatively affected with levels of device frequency (kHz), exposure time intervals (min) and measuring distance in the field. However, the bird’s departure time (min) was positively affected with levels of device frequency and with exposure time. While, the similar effect was obtained for bird’s departure time at measuring distance in the field. Finely the results indicated strongly that the most important factors were the frequency and the exposure time which consider effective in pest birds deterrent for the target species mentioned in this study. Low frequency (1; 3 kHz) which increase scaring influence to the pest birds was greater than the high frequency and caused high levels of sound pressure levels (SPL). Also, in the birds departure time Dove, Pigeon and Sparrow flock never returned to the initial position to attack the field crops after only 5 min, but Crow after only 10 min. | ||
