Résumé en langage clair

Vibration pest control is a novel and experimental pest control alternative to chemical
pesticides. Most evidences have been obtained from small scale, short-term experiments. In this study, our objectives were to test this approach over a long period of time, and with larger plants. We exposed green peach aphids on short pepper plants to vibration over a two-week period. We also tested vibrations on aphids feeding on large, commercial size plants over a two-week period. In both cases, the population growth was greatly reduced, but for larger plants, the efficacy was reduced. This is most likely due to a reduction in the vibration intensity. Larger, more powerful shakers will need to be used in future large-scale experiments.

Résumé

Vibrational pest control is a novel and experimental pest control alternative to chemical
pesticides. Most experimental evidences on the efficacy of vibrational pest control have been
obtained from small scale, short-term experiments. In this study, our objectives were to
understand the effect of vibrational treatment over a long period of time, and with larger plants.
For the duration, we exposed green peach aphid Myzus persicae on 30 cm pepper plants to a
vibrational treatment over a two-week period. For the larger plants, we tested our vibrational
treatment on aphids feeding on plants ranging from 1.5 to 1.8 m pepper plants over a two-week
period. In both cases, the population growth was greatly reduced, but as plants grow larger, the
efficacy was lessened. This is most likely due to a reduction in the vibration intensity through the
plant. Larger, more powerful shakers will need to be used in future large-scale experiments.
