We evaluated the potential efficacy of two entomopathogenic nematode species for suppression of plum curculio in northern regions, targeting life stages that reside in soil during spring and summer. A strain of Heterorhabditis bacteriophora isolated from soil infested with plum curculio in northern Utah and a commercially available strain of Steinernema feltiae known to tolerate cool temperatures were tested in the laboratory against three life stages of plum curculio. Bioassays used the southern strain of plum curculio because availability of the northern strain from the field was inadequate. H. bacteriophora was more virulent than S. feltiae to all plum curculio life stages. Adults and pupae were more susceptible than larvae. Temperature bioassays were conducted with a surrogate host: last instars of Galleria mellonella. The two nematodes exhibited different, but overlapping, thermal activity ranges. Both species performed best at 20[degree]C: virulence and reproductive potential was higher; however, H. bacteriophora was superior to S. feltiae at 30[degree]C and vice versa at 10[degree]C. The reproductive potential of H. bacteriophora was >2.5 times greater than for S. feltiae, and H. bacteriophora required fewer individuals to initiate a successful host infection. S. feltiae was a better fit for temperatures expected in northern climates, but H. bacteriophora was more virulent to plum curculio and produced more infective juveniles that may benefit nematode recycling and continuation and spread of insect suppression in the field.}, keywords = {Conotrachelus nenuphar}, isbn = {0046-225X}, author = {Kim, H.

Our results revealed the significant impact of vegetation on successful insect dispersal, whether tagged or not. The vertical movement of these insects on stems, stalks, and tubes was also unaffected by the presence of vertical tags. Trailing tags had a significant negative effect on the vertical movement of the western corn rootworm.

This study evaluated whether the efficacy of this technology is sufficient to track insects in vegetative landscapes. RESULTS: Field efficacy data were collected using portable harmonic microwave radar and electronic dipole tags mounted on adults of three economically important pests: Leptinotarsa decemlineata (Say), Diabrotica virginifera virginifera (LeComte) and Conotrachelus nenuphar Herbst. Detection and recovery of tagged Colorado potato beetles, plum curculios and western corn rootworms was high within and among potato plants, moderate within apple trees and high within, but not between, corn plants respectively. The efficacy of the radar depends on the ability of the operator to move around the host, scanning for a signal {\textquoteright}sightline{\textquoteright} with the tagged insect among plant structures. CONCLUSION: The detection rate of tagged insects by harmonic radar systems is high enough to track the walking path of pests through low row crops such as potato, tall row crops such as corn or tall but well-separated trees of orchard-type crops by adapting the scanning procedure to the vegetative architecture.

The heaviest tag mounted on the pronotum of the Colorado potato beetle, Leptinotarsa decemlineata (Say), reduced its mean horizontal speed slightly but significantly. The mean horizontal speed of plum curculio, Conotrachelus nenuphar (Herbst), was significantly reduced by a light tag but not by heavier tags. The mean horizontal speed of the western corn rootworm, Diabrotica virgifera virgifera (LeConte), increased slightly when a tag was attached.

Changes in the walking speed were variable but remained well within the range of values recorded in the literature. The impact of the additional tag weight was within the range of constraints to movement (e.g., slopes, barriers, etc.) normally experienced by insects in their environment. The results confirm that tags presently available will have minimal impact on the walking behavior of Colorado potato beetle, provide an estimate of the optimal tag weight for the plum curculio and show that a lighter tag and a better attachment method are required for the western corn rootworm.

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 equal] 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.

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 [approximately equal]245 and 1105 (base 10[degree]C, biofix of 1 January), respectively.

The results suggested that the northern and the southern clades correspond with northern strain and southern strain of plum curculio. The three-group model of AMOVA test may suggest that there is a transitional group existing between northern and southern groups. In this study, the mtCOI sequence was highly informative as a molecular marker in that it could distinguish C. nenuphar from northern and southern geographic locations in the eastern United States.}, keywords = {Conotrachelus nenuphar}, isbn = {0013-8746}, author = {Zhang, Xing and Tu, Zhijian and Luckhart, Shirley and Pfeiffer, Douglas G.} } @article {2874, title = {[Biology and description of two immatures of Conotrachelus imbecilus Fiedler (Coleoptera: Curculionidae: Molytinae) found on fruits of Inga heterophylla.]}, journal = {Boletim do Museu Paraense Emilio Goeldi Serie Zoologia}, volume = {10}, number = {2}, year = {1994}, note = {Biologia e descricao dos imaturos de Conotrachelus imbecilus Fiedler (Coleoptera: Curculionidae: Molytinae) em frutos de Inga heterophylla.}, month = {Dezembro}, pages = {253-271}, type = {Article}, keywords = {Conotrachelus}, isbn = {0077-2232}, author = {de Melo Valente, Roberta and de Sousa Gorayeb, Inocencio} } @article {2766, title = {Nomenclatural changes in New World Curculionidae (Curculioninae (Cryptorhynchini, Molytini), Cossoninae)}, journal = {Coleopterists Bulletin}, volume = {52}, number = {3}, year = {1998}, month = {September}, pages = {285-290}, type = {Article}, abstract = {The genus Epacalles Kissinger with its one included species, E. inflatus (Blatchley), is transferred from Cryptorhynchini to Molytini, Conotrachelina Epacalles is closely related to species placed in the genera Aenesias Champion and Lepilius Champion.
