Abstract/Contents: | "The range and severity of impact from the annual bluegrass weevil, Listronotus maculicollis, is expanding across the eastern U.S. Adults overwinter in protected areas off-course, but the life cycle is completed on low-cut turf, particularly fairways dominated by Poa annua. To better target the insect with control tactics, we need to understand the relationship between overwintering and developmental habitats. Our objectives were to identify the factors that influence selection of overwintering sites and how the insect disperses to and from those sites. Major findings include: Based on a survey of natural populations, adults tend to overwinter near tree lines, up to 60 meters from the fairway and 10 meters past the tree line, but not on or near the fairway. Based on a survey of natural populations and an experimental choice test, adults do not prefer white pine litter as an overwintering substrate over deciduous tree litter or grass cover. Based on linear pitfall trapping, adult movement on the ground peaks in spring and shows directionality toward the fairway from the tree line. There was no peak of activity or directionality in the fall. We thereby propose a new conceptual model of flux between overwintering and developmental habitats based on the orientation of flying adults to defined tree lines. Further defining this behavior will strengthen our ability to target this major turf pest in both space and time - with control tactics." |
