| Abstract/Contents: | "The annual bluegrass weevil (ABW), Listronotus maculicollis, is the most important and difficult to control insect pest of short-mown golf course turf and grass tennis courts in the northeastern US and Eastern Canada. Severe damage to grass plants is caused by the larvae that initially tunnel stems, later feed externally on the crowns, each killing up 20 plants during their development. The pest has consistently expanded its range of impact over the last decades with severe infestations now reported from all states of the Northeast and Mid-Atlantic. There is no reason to believe this expansion is going to slow any time soon. Presently, chemical insecticides are the only effective option for ABW control with turf managers typically preventively applying insecticides over much of the short-mown areas of the golf course, often 2-6 times during the season. Overuse of synthetic insecticides has led to the development of insecticide-resistant populations some of which are already resistant to most of the presently available chemistries. Clearly, the sole reliance on chemical insecticides is no longer sustainable. There is an urgent need to develop better IPM tools to assess and monitor its impact, and to develop more effective management practices. Therefore, the overall goal of the proposed research is to develop a basis for more effective and sustainable methods for the management of annual bluegrass weevil populations by pursuing three different aspects of IPM: monitoring methods, plant resistance/tolerance, and biological control. Effective and reliable monitoring is a cornerstone of IPM. Available ABW monitoring methods are nto effective and/or too labor intensive, and hence are rarely used. In addition, the extraction efficiency of these methods and factors that affect it are poorly understood. We propose to determine extraction efficiencies of various adult and larval monitoring methods and to optimize them to make them more feasible for practitioners. We also propose to search for semiochemical attractants (pheromones, host-plant volatiles) and study the behavioral and physiological responses of male and female weevils to these compounds and blends thereof with the long-term goal of developing attractant-based monitoring and/or management tools. Plant resistance/tolerance to pests is the most likely to be successful component in IPM. While P. Annua is considered to be a preferred host of ABW and/or particularly susceptible to it, experimental evidence for host preferences is very limited and variable. And there are an increasing number of field observations on ABW damaging creeping bentgrasses. We propose to determine the susceptibility to ABW and suitability as ABW hosts of different bentgrass species/cultivars in comparison with annual bluegrass. The proposed research will give superintendents (1) a better understanding on the threat that ABW poses to their various existing turf areas and (2) essential knowledge for the selection of turfgrass species/cultivars for the replacement of annual bluegrass with more sustainable turfgrasses. In view of the threat of resitance development and the death of effective synthetic insecticides to manage resistant ABW populations, we also propose to develop alternatives for the control of ABW larvae. Entomopathogenic nematodes have already been shown to have potential for ABW larvae control, but their performance was variable and declined at high ABW densities. Nematodes and the neonicotinoid imidacloprid interact synergistically on white grub mortality with no negative effects on the nematodes. These combinations seem also quite feasible against ABW larvae since imidacloprid is already widely used for white grub management and combinations could be applied at the appropriate time to control both ABW larvae and white grubs." |
