“…5). These Vaccinium species are all ßeshy enough to serve as suitable hosts for C. nenuphar larvae, but in our surveys were not widely used as a host by plum curculio, despite the fact that V. corymbosum is reported as a regular host of plum curculio in both New Jersey and North Carolina (Beckwith 1943, Mampe and Neunzig 1967, Polavarapu et al 2004.…”

“…Throughout its habitat, plum curculio uses a broad range of hosts, including plants in the Rosaceae (Quaintance andJenne 1912, Maier 1990) and in the Ericaceae (Stearns 1931, Mampe and Neunzig 1967, Polavarapu et al 2004. Prunus angustifolia Marshall (Chickasaw plum), a thicket-forming species that occurs frequently on Þeld or woodline edges, is the predominant native plum species in central Georgia and is believed to be the primary host for the overwintering generation of plum curculio.…”

“…Cultivated hosts in the family Rosaceae based on the studies of Maier (1990) (Howitt, 1993) and apricot, Prunus armeniaca L. (Howitt, 1993;Brown, 2005). In the family Ericaceae, highbush blueberry, Vaccinium corymbosum L. (Beckwith, 1943;Mampe & Neunzig, 1967;Polavarapu et al, 2004) and deerberry, Vaccinium stamineum L. are considered to be hosts. In the family Vitaceae, plum curculio larvae were found to be developing successfully in muscadine, Vitis rotundifolia Michaux (Jenkins et al, 2006).…”

We assessed host preference of adult plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), based on the total number of mark-released and wild adults recovered and the total distance moved by mark-released adults in an orchard whose layout was designed to specifically allow foraging plum curculios to choose among host tree species. Host trees included apple, Malus domestica Borkh.; pear, Pyrus communis (L.); peach, Prunus persica (L.) Batsch; apricot, Prunus armeniaca L.; tart cherry, Prunus cerasus L.; sweet cherry, Prunus avium (L.); European plum, Prunus domestica L.; and Japanese plum, Prunus salicina Lindl. (all Rosaceae). We released 2900 marked adults and recovered 17.7%. We used screen traps to provide a measure of the number of adults that arrived at and climbed up particular host trees and found that significantly greater numbers of marked adults and the greatest number of wild adults were recovered from screen traps attached to Japanese plum. We sampled host tree canopies by tapping limbs to provide a measure of the number of adults within a tree canopy at a particular moment. Again, significantly greater numbers of marked and wild adults were recovered from plum species, with no difference between Japanese and European plum cultivars for marked individuals, but with significantly greater numbers of wild individuals recovered from Japanese plum. The preference index (PI) for Japanese plum based on total distances moved by all marked adults recovered on Japanese plum divided by the total distance moved by marked adults recovered on other host trees indicated that Japanese plum was the most highly preferred host, followed by European plum, peach, sweet cherry, tart cherry, apricot, apple, and pear, respectively.

The plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is a key pest of peaches, Prunus persica (L.) Batsch, in North America. Captures of adult weevils in unbaited pyramid traps recorded annually from 2000 to 2008 in an unmanaged peach orchard in central Alabama were used to determine its seasonal occurrence and to develop predictive degree-day models. Spring migration of plum curculio began at bloom (early to mid-March). Linear, polynomial, and three-parameter Weibull functions were tested to describe the relationship between weekly trap capture and cumulative degree-day (DD). Criteria used to select the best models were the smallest Akaike information criterion and highest R2 values. A sixth-order polynomial function fitted best to seasonal trap captures and cumulative DDs and revealed two major seasonal peaks with the first (spring generation) and second (summer generation) peaks occurring at cumulative DDs of ≈245 and 1105 (base 10°C, biofix of 1 January), respectively. A potential third (late summer generation) peak was observed at 1758 DDs. The sixth-order polynomial model predicted the first trap capture to occur at cumulative DD of ≈99 (base 10°C, biofix of 1 January). The three-parameter Weibull model predicted the first trap and first peak (spring generation) trap captures to occur at mean cumulative DDs of 108.02 ± 9 and 220.07 ± 16, respectively. Validation of the models in the unmanaged orchard in 2009 and 2010 and in a second unmanaged orchard (located 1.6 km from the first) in 2009 showed that the polynomial and Weibull were within ±7 d in their predictions of the first and peak trap captures of the spring population. Validation results showed that both models successfully predicted the first trap capture in one out of three scenarios and the peak trap capture in two out of three scenarios. The performance of the models is discussed in relation to management of plum curculio in central Alabama.
