Abondance saisonnière des espèces de pyrales des prés (Lepidoptera : Crambidae) associées aux graminées à gazon au Québec
[Seasonal abundance of the sod webworm species (Lepidoptera: Crambidae) associated with turfgrass in Quebec]
Phytoprotection 84 (2), 69-75
Abstract: Fifteen lawns in Quebec City and Montreal, Quebec, Canada, were sampled in 1998 and 1999 to establish the sod webworm species complex associated with turfgrass and to determine the damaging species at the larval stage. Sod webworm adults were captured with light traps from June to September. A golf cup cutter served to monitor larvae in sod with webworm damage. Eleven sod webworm species were captured with light traps in 1998 and four in 1999. Three of these species were dominant: Crambus preafectellus (silver-striped webworm), Pediasia trisecta (larger sod webworm) and Chrysoteuchia topiaria (cranberry girdler). The seasonal abundance of these species at the adult stage was established during the summer of 1998 and 1999. The cranberry girdler was the only species that caused damages to the turf.
