Data were analyzed separately for each of the two years (2013 and 2014) and for each of the two fruit sampling dates (pre- and post-sprays). analyzed data and conducted statistical analyses. Data were sorted by year (1994-2000), by state (AR or OK), and orchard site. McCraw This 2-year study (2013–2014) assessed the efficacy of an odor-baited “trap bush” approach to aggregate plum curculio, Conotrachelus nenuphar, adult injury, i.e., number of oviposition-scared fruit, in four commercial highbush blueberry farms in New Jersey (USA). Our full models included the independent variables: “Treatment” (trap bush versus control), “Location” (forest edge versus interior edge), “Farm”, and the 2- and 3-way interactions among them. those of the individual authors and contributors and not of the publisher and the editor(s). ; Nannini, R.; Marianelli, L.; Roversi, P.F. ; Dynok, S.A.; Piñero, J.C. Odor-baited trap trees: A new approach to monitoring plum curculio (Coleoptera: Curculionidae). N.F. Effects of the insect growth regulator, novaluron on immature alfalfa leafcutting bees. The pyramid trap was reported as an effective monitoring tool that attracts pecan weevils and other weevil species that walk up tree trunks. You could not be signed in. S.B. (1998). Fruit damage was ≥1% in 19 out of 22 cases where the pyramid trap catch exceeded the threshold of 0.045 plum curculio adults per trap per day (Fig. ; Barbour, J.D. W.G. Lewis 1). ; Hui, F.K.C. From 1995 on, each trap was kept visible by periodic hoeing or hand-removal of tall weeds. Evaluation of individual components of plum odor as potential attractants for adult plum curculios. Edge and center trap counts were similar in Arkansas only in the VB site in 1998. The economic threshold of 0.045 adults per pyramid trap per day was derived from the following linear equation (t = 5.37, df = 28, P < 0.0001, r2 = 0.51): D = 0.33 + 14.49 * X; where X is the number of plum curculio adults per pyramid trap per day (range, 0.01-0.4 adults); and D is the assessed percentage of fruit damaged 1 wk after recording the trap counts (range, 0-8% damage). doi: ; Faubert, H.; Koehler, G.; Los, L.; Morin, G.; Leahy, K.; Cooley, D.R. One side was painted with a medium gray paint (50:50 black/white), whereas the other side was painted with dark gray paint (9:1 black/white). Fine, J.D. In comparison, AR, populations in the orchard edge usually exceeded 0.9 adults/trap. All trap data and percentage damage data (1 wk later) were collected from the following orchards in several cities of Arkansas and sample dates: Forrest City (F) on 15 and 29 April, 5 May, 6 June 1997, 26 May 1998; Haynes (H) on 29 April, 4 and 11 June 1997, 2, 14, and 24 April, 26 May, 4 and 17 June, and 8 July 1998; Wynne (B and KL) on 14, 24, and 30 April, 13 May, 29 June 1998, 28 April, 28 May, 4 and 18 June 1999; Colt (S) on 1 May 1998; Clarksville (MO) on 27 May and 6 July 1999, 3 April 2000; and Conway (G) on 11 April 2000. It was as low as 0.76 adults/trap in orchard VB in 1995. R.F. The screen trap can also capture plum curculio adults in peaches (Johnson et al. Virulence of entomopathogenic nematodes to plum curculio. Black wooden pyramid traps placed on the ground next to apple tree trunks captured more adults than black plastic cylinder traps placed vertically on limbs within apple tree canopies, squares of clear Plexiglas placed vertically next to apple tree canopies to intercept incoming adults on the sticky-coated outward-facing surface, or “Circle” traps comprised of aluminum screen and fastened to limbs within apple tree canopies (which captured no adults). As data on the proportion of scarred fruit per fruit were close to zero values, there was no need to use the arcsine square root transformation [, Baiting blueberry bushes with the combination of grandisoic acid and benzaldehyde had a significant effect on the mean proportion of. (1987), who used other sampling methods to describe the edge effect that occurred during the spring and late summer dispersal phases of plum curculio adults. 1992,1993). J.R. C. Johnson The lure effect on trap counts recorded in 1997, 1999, and 2000 in Arkansas and 1997 in Oklahoma was removed from the mean trap counts by incorporating lure effect into the mean error value (see footnotes in Tables 3 and 4). In 1996, the PK orchard and the Porter (P) orchard each had five pyramid traps (three along the edge and two in the center), whereas the two ST orchards had three traps along the edge. The wood lath added support to the cone. Each block had traps either with no bait or baited with a lure of grandisoic acid, the plum curculio aggregation pheromone (all lure effects reported elsewhere). This trap appears to mimic a tree trunk (Tedders and Wood 1994, Tedders et al. Leskey, T.C. Racette et al. These two estimates of population levels of plum curculio adults around and in peach trees were compared with percentage new catfaced fruit (30 fruit from each of 10 trees). Studies were conducted in 2013 and 2014 in commercial highbush blueberry, The study was conducted in 2013 and 2014 in eight experimental plots across four commercial blueberry farms (two paired plots per farm) located in Hammonton, New Jersey (Farm A: 39°33′23.48″N, 74°46′35.64″W; Farm B: 39°32′45.06″N, 74°47′19.47″W; Farm C: 39°35′37.50″N, 74°46′21.21″W; Farm D: 39°38′35.37″N, 74°40′22.14″W). Type III Mean Square with Trap * Block as an error term, Effect of trap location (L) and trap type (T) on counts of plum curculio adults per trap in Oklahoma. Growers used this IPM program to assist in determining when plum curculio populations exceeded economic thresholds. Also, an economic threshold was derived based on a linear regression of pyramid trap captures to percentage fruit damage assessed 1 wk after traps were sampled. Maleckas (1996) found the pyramid trap worked well by itself as a monitoring tool for plum curculio in Michigan apples, whereas Prokopy et al. (Aldrich et al. Ronald J. Prokopy, Bradley W. Chandler, Tracy C. Leskey, Starker E. Wright; Comparison of Traps for Monitoring Plum Curculio Adults (Coleoptera: Curculionidae) in Apple Orchards. In 1999, peach orchard VL had traps arranged in a randomized complete block design (3 replicates) each consisting of four screen traps and four pyramid traps. Pyramid traps have problems including warping of the Masonite base and having the trap top or the pyramid trap base dislodged by severe winds or livestock. Only one orchard in Oklahoma and another in Arkansas had smaller circumference tree trunks (<38 cm) than the other orchards resulting in significantly more plum curculio adults captured in pyramid traps than in screen traps.
