Population dynamics of the soybean aphid (Hemiptera: Aphididae) in Quebec (Canada)
Journal of Economic Entomology 109 (3), 1465-1468
Abstract: The population dynamics of the soybean aphid (Aphis glycines Matsumura) was studied over a 12-yr period (2004–2015) from archive and field data collected in the Montérégie area of Quebec (Canada). As observed in the United States, a 2-yr oscillation cycle was observed from 2005 to 2011 in Quebec, with high infestations during odd years, while the opposite was found in 2014 and 2015. A broader pattern could also be observed, with high infestation in two consecutive years every 10 yr. In addition, the infestation intensity observed in high infestation years decreases throughout the years, which questions the evolution of the oscillation cycle in the future.
