Nonfruiting Host Tree Volatile Blends: Novel Attractants for the Plum Curculio (Coleoptera: Curculionidae)

Field Evaluation of Traps and Lures for Monitoring Plum Curculio (Coleoptera: Curculionidae) in Alabama Peaches

“…The search for semiochemical attractants for plum curculio has resulted in the identiÞcation of various plant-based volatiles, the most attractive of which include benzaldehyde (BZ) and foliar and woody tissue of plum trees (Leskey andProkopy 2000, 2001;Leskey et al 2005). Grandisoic acid (GA), a male-produced aggregation pheromone of plum curculio, also was identiÞed as attractive to both sexes of plum curculio (Eller and Bartelt 1996).…”

“…To date, a synergistic lure composed of BZ and GA, developed in Massachusetts remains the most widely used attractant for monitoring plum curculio in apple (Malus spp.) orchards in the northeast (Piñ ero and Prokopy 2006), and in peach orchards in the mid-Atlantic (Piñ ero et al 2001, Leskey and Wright 2004b, Leskey et al 2005. Prokopy et al ( , 2004a also developed the trap-tree approach, a simple and effective integrated pest management (IPM) tool that allows growers to determine need for and timing of insecticide applications based on occurrence of fresh oviposition injury by plum curculio to apple fruit that are monitored on a perimeter-row trap tree.…”

“…The majority of the research on evaluation of monitoring traps and lures for plum curculio have been conducted in apple orchards in the northeastern United States (Piñ ero and Prokopy 2003; Leskey and Wright 2004a,b;Leskey et al 2005). Very little has been done to evaluate the performance of traps and lures for monitoring plum curculio in peach orchards in Alabama and other parts of the southeastern United States.…”

Behavioural responses of wheat stem sawflies to wheat volatiles

“…Trap cropping can take advantage of insect -plant interactions by augmented amounts of semiochemicals using a 'push -pull' or stimulo-deterrent strategy where repellent and attractive stimuli are deployed in tandem to manipulate the distribution of insect pests, reducing reliance on insecticides ( Miller & Cowles, 1990;Cook et al , 2007 ). Plant compounds can be used in traps alone ( Katsoyannos & Guerin, 1984;Martel et al , 2005a , b;Ruther & Mayer, 2005 ) or to synergize the effect of pheromones in trap catches ( Nakamuta et al , 1997;Reddy et al , 2004;Leskey et al , 2005 ) for mass trapping, monitoring or in attracticide strategies. Another potential use of semiochemicals in pest management is application of volatile compounds that act as repellents ( Pettersson et al , 1994;Borden et al , 1997 ).…”

Laboratory Evaluation of Flight Performance of the Plum Curculio (Coleoptera: Curculionidae)

“…In the spring, these adults migrate toward host trees to feed on and oviposit into the developing fruit, causing scarring, malformation, and fruit drop (Johnson et al 2005). Because of the economic importance of the plum curculio as an orchard pest, factors affecting its migration from the overwintering quarters into fruit orchards have received considerable attention (Smith and Flessel 1968, Laßeur and Hill 1987, Yonce et al 1995, Dixon et al 1999, Leskey and Prokopy 2000, Leskey et al 2005.…”
