“…The response index data also supported the above-mentioned results, which generally hold true for both generations of plum curculio. Our results agree with previous studies which reported the superiority of pyramid traps over Circle traps and other trap types for monitoring plum curculio adults in fruit orchards (Le Blanc 1982, Le Blanc et al 1984, Yonce et al 1995, Mulder et al 1997, Johnson et al 2002, Laßeur et al 2007). In contrast, Johnson et al (2002) reported similar plum curculio captures in pyramid versus Circle traps in most of their samples.…”

The plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is a key pest of peaches, Prunus persica (L.) Batsch, in North America. We evaluated the effectiveness of two widely used trap types (pyramid versus Circle traps) and commercially available synthetic lures for monitoring the pest in two peach orchards in Alabama during 2008 and 2009. The lures evaluated alone or in combinations included benzaldehyde (BZ) (a component of fruit odor), plum essence (PE) (a mixture of fruit odor extracted from food grade plum), and grandisoic acid (GA) (a male-produced aggregation pheromone of plum curculio). In general, pyramid traps captured more plum curculio adults than Circle traps, particularly during the first generation. Trap performance was improved numerically by the addition of BZ, PE, or GA alone (single lures) and was significantly enhanced by the addition of the combined BZ + PE lure. In both first and second generations, the combined BZ + PE lure increased plum curculio captures (significant in some trials) over unbaited traps and traps baited with single lures by approximately 1.5-21-fold and had the highest response indices (RIs), which is indicative of high attractiveness. The combined BZ + GA lure and the three-component BZ + PE + GA lure also captured numerically more plum curculio adults than unbaited traps or traps baited with single lures but the differences were rarely significant. Analysis of ratios of interaction suggests the possibility of synergistic interactions between BZ and PE and between BZ and GA; however, additive effects were concluded due to high sample errors. These results are discussed in relation to the physicochemical properties of the lures and the potential of using baited monitoring traps to aid plum curculio management decisions in peach orchards.

“…Trap types evaluated to date for monitoring plum curculio include conical colored and rectangular white cardboard sticky traps (Le Blanc 1982), scoutapples (Le Blanc et al 1984), green-painted plastic sticky spheres (Yonce et al 1995), Circle traps (Mulder et al 1997), and black pyramids, black cylinders, and vertical clear Plexiglas panels (Mulder et al 1997, Prokopy and Wright 1998, Dixon et al 1999, Prokopy et al 1999a. Combined results from these studies indicate that black pyramid traps (mimicking tree trunks), clear Plexiglas panels (for capturing ßying adults), black cylinder traps (mimicking tree branches), and Circle traps (for intercepting adults walking on tree trunks or limbs) may hold the greatest potential for use as plum curculio monitoring tools.…”

Response of overwintered plum curculios, Conotrachelus nenuphar (Herbst), to odor-baited traps was evaluated from the beginning until nearly the end of emigration from overwintering sites in woods. We evaluated clear sticky Plexiglas panels and black pyramid traps placed close to woods adjacent to apple trees in an unsprayed section of an orchard. Traps were baited with aggregation pheromone (grandisoic acid) alone or in combination with one of six synthetic fruit volatiles (benzaldehvde, decyl aldehyde, E-2-hexenal, ethyl isovalerate, hexyl acetate, or limonene). Unbaited traps served as a control treatment. Plum curculio emigration from woods was divided into early-, mid-, and late-season periods based primarily on phenological stage of apple bud and fruit development (tight cluster to bloom, petal fall, and fruit set, respectively). During both early- and late season, panel and pyramid traps baited with benzaldehyde plus pheromone were significantly more attractive than any other traps (baited or unbaited), except panel traps baited with ethyl isovalerate plus pheromone in early season, which likewise captured significantly more adults than unbaited panel traps. During midseason, no lures were significantly attractive, possibly due to prevailing cool weather, unfavorable for adult activity. Over the entire season, panel or pyramid traps baited with benzaldehyde plus pheromone captured nearly six times as many plum curculios as unbaited traps of each type, whereas traps baited with pheromone alone captured about twice as many as unbaited traps of each type. We provide information on sex ratio, female maturity stage, and mating status, and several weather parameters associated with trap captures. We conclude that panel or pyramid traps, or a combination, baited with benzaldehyde plus pheromone placed at borders of plum curculio overwintering sites can be a valuable tool for monitoring the beginning, peak, and end of adult immigration into apple orchards.

“…Beating trays have been used to sample pests not attracted to chemicals or specific colors; examples include the pear psylla (Burts and Retan, 1969) and plum curculio (Wylie, 1951). Le Blanc et al (1984) hung mature fruit obtained from winter storage in trees to monitor activity of the plum curculio in spring.…”
