Design and Preliminary Testing of a Pneumatic Prototype Machine to Control the Colorado Potato Beetle
Bibliographic record
Abstract
Highlights A pneumatic prototype machine to control the Colorado potato beetle (CPBs) was successfully designed, built, and tested in a potato field under real conditions. The pneumatic prototype machine is effective in dislodging CPB larvae from potato plants. ABSTRACT . The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is a real threat to potato crops when left uncontrolled. This insect pest is hard to control because it develops resistance to most chemical insecticides. To date, several alternatives including chemical, biological, and physical methods have been used to control CPB populations but have proven to be ineffective on their own. So far, the most reliable method at short and medium scales has been the use of chemicals, i.e., spraying insecticides onto potato plants at regular intervals throughout the life cycle of the CPB. However, the overuse of chemicals due to the resistance developed by the CPB can lead to serious health and environmental problems. The use of a pneumatic method to control the CPB seems to be a viable alternative compared to the use of chemicals. For this purpose, this research focused on engineering a pneumatic control device that could allow farmers to reduce their reliance on chemical insecticides. A pneumatic prototype machine using positive air pressure to dislodge CPBs from potato plant foliage was designed and built at the Department of Soils and Agri-Food Engineering of Université Laval. This prototype was tested in the field using three airflow velocities (31, 35, and 38 m/s) and two travel speeds (5 and 6 km/h). The results indicated that the airflow velocity and travel speed have no significant impact on dislodging the CPB (p = 0.0548 and 0.7033, respectively). However, the interaction between airflow velocities and the development stages of the CPB had a significant effect on dislodging the CPB (p = 0.0194). Overall, the most adequate airflow velocity that resulted in removing most of the CPB larvae from potato leaves was 35 m/s. Obtained results indicate that this pneumatic prototype machine could be efficiently used to control the CPB. However, extensive testing is required to confirm obtained results and investigate the effects of the pneumatic control on both the potato plant growth and the yield compared to other control means.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
