Description: The effects of different combinations of airflow velocity and travel speed on the dislodging and collection ofadults and fourth instar larvae (L4) of Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say), were investigated. Two series of experiments were conducted for this purpose, one in the laboratory and the other in the field. In the laboratory, CPB adults were exposed to horizontal airstreams of different velocities ranging from 20 to 35 mls at three different levels of travel speed (4, 6, and 8 krnIh). In the field, L4larvae were also exposed to horizontal airstreams of 20, 30, and 40 mls at three travel speeds (2, 4, and 6 km/h). Results revealed that both airflow velocity and travel speed significantly increased the dislodging of CPB adults and L4 larvae. The collection of CPB adults and L4 larvae also significantly increased with increasing airflow velocity. However, the travel speed did not have any significant effect on the collection of adults and L4 larvae. A passive collecting device was adequate. Compared with a vacuuming collecting system, this passive device could greatly reduce the power requirements. The overall results obtained with the prototype were satisfactory. However, more work is needed to improve the dislodging of CPB. This could be achieved by integrating a mechanical shaking system to the prototype machine.
