Abstract:

A 3-yr study using different sampling and trapping techniques showed that the arthropod pest fauna in two commercial vineyards in southwestern Quebec was qualitatively and quantitatively different than that of Ontario, Canada, and NewYork state. We hypothesize that a colder winter climate in addition to the agronomic activity of earthing up around the vines in autumn to protect the roots from freezing in winter contributed to low numbers of pests, such as the grape berry moth, Endopiza viteana Clemens (Lepidoptera, Tortricidae). Once in 3 yr, the density of this pest approached, in one of the vineyards, the action threshold recommended for New York. Therefore, it should be monitored on an annual basis. Another phytophagous arthropod that has the potential to cause sporadic economic damage is the potato leafhopper, Empoasca fabae (Harris). The Asiatic garden beetle, Maladera (=Autoserica) castanea (Arrow), was reported for the first time in Canada. The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), was also captured by sampling. However, its status as a pest has yet to be clarified.
