Abstract

In southwestern Quebec, cereal aphids started to infest cereals in the first week of June, and reached their peak on the second and third weeks of July. There was a significant correlation between the number of alate aphids produced and total number of aphids per colony for R. padi and M. avenae but not for R. maidis. The percentage of alate aphids in colonies of all three species increased as cereals matured. The index of aggregation (b) showed M. avenae was distributed randomly in the field while R. padi and R. maidis were distinctly aggregated.

Résumé

Au sud-ouest du Québec, les pucerons des céréales ont envahi les cultures durant la première semaine de juin et ont atteint leur sommet d’abondance durant la deuxième et la troisième semaine de juillet. Une corrélation significative a pu être établie entre le nombre d’individus ailés et le nombre total de pucerons par colonie pour R. padi et M. avenae mais pas pour R. maidis. Le pourcentage d’ailées dans les colonies de ces 3 espèces a augmenté avec la maturation des céréales. L’indice d’agrégation (b) a révélé que M. avenae se distribue au hasard dans les champs, alors que R. padi et R. maidis forment clairement des agrégats.
