Project Methods BIOLOGY AND BEHAVIOR. There are many insecticides available for plum curculio control, but their performance characteristics vary greatly compared to our traditional broad-spectrum chemistries. Odor-baited trap trees: a novel management tool for plum curculio (Coleoptera: Curculionidae). Field evaluation of plant odor and pheromonal combinations for attracting plum curculios. Sticky clear Plexiglas panel traps placed at orchard borders, designed to intercept adults immigrating from border areas by flight, captured significantly more adults than similarly placed black pyramid traps, which are designed to capture adults immigrating primarily by crawling, or Circle traps wrapped around trunks of perimeter-row trees, which are designed to intercept adults crawling up tree trunks. Although this may be a weird and uncertain time of the year, if you have varieties at or near petal fall, it is time to start preparing your plum curculio management program. Please enable it to take advantage of the complete set of features! Gӧkçe A, Stelinski LL, Nortman DR, Bryan WW, Whalon ME. 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. iv ACKNOWLEDGEMENTS Thank you so much to the many people who helped in the creation of this dissertation, either by supporting the research or by supporting me. Dead-Inn Pyramid trap for Growers. Traps are a good indicator of likely plum curculio pressure in the area, and should be placed on the borders of orchards w… Please enable it to take advantage of the complete set of features! 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. Eggs are deposited under the skin of the fruit in a small, crescent-shaped cavity (Figure 1). Left unattended Plum Curculio can damage 50-90% of the fruit. If plum curculio infestation occurs and a rescue treatment is needed, organophosphates and neonicotinoids can provide curative action up to two weeks after plum curculio infestation, although in some cases dead cadavers can still be found in fruit. 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. J Econ Entomol. It generally attacks in early spring, but the damage will continue throughout the season. Figure 1. In 2012, 167 plum curculios were observed in the trap tops, of which 111 plum curculio were in the v.I traps and 56 in the v.II traps. 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. 2013 Apr;69(4):464-70. doi: 10.1002/ps.3445. Pyramid traps are the most efficient means of monitoring plum curculio activity early in the season. A concurrent experiment revealed that addition of other synthetic fruit odor attractants to apple trees baited with benzaldehyde plus grandisoic acid did not enhance aggregation of ovipositional injury above that of this dual combination. NLM COVID-19 is an emerging, rapidly evolving situation. J Econ Entomol. While we only collected a few, this indicates that plum curculio are becoming active in middle Georgia peaches. A more practical method than limb jarring is needed to monitor the plum curculio, Conotrachelus nenuphar (Herbst), in peach trees. | Behavioral and electroantennogram responses of plum curculio, Conotrachelus nenuphar, to selected noxious plant extracts and insecticides. Epub 2012 Dec 4. ABSTRACT The plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is a key pest of peaches, Prunus persica (L.) Batsch, in North America. Adults migrate into the orchards each spring. J Econ Entomol. 1992, Vincent et al. J Econ Entomol. Yesterday on March 17, 2020, we collected our first plum curculio of the season in one of our traps in Byron, GA. [2004]) were deployed within and adjacent to the orchard to monitor timing and duration of emergence of plum curculio. Warmer climates may see both e… 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).
