INTRODUCTION An experiment was conducted beginning in 2003 at a certified organic apple orchard in Iowa to evaluate insect pest and disease incidence in four scab– resistant apple cultivars (Delate et al., 2005). This on-farm experiment was resumed in 2007 after new grant funds were secured to compare pest loads with previous years’ results. The objective of the on-farm demonstration was to com...

Abstract Certain species of acorn- and nut-feeding weevils, Curculio spp. (Coleoptera: Curculionidae), have become significant insect pests cultivated hazelnuts (Corylus spp.) (Fagales: Betulaceae) worldwide. The significance weevils that feed on injure is increasing as countries such the United States China continue to develop hybrids hazel plants increase their hazelnut production. This revie...

The plum curculio, Conotrachelus nenuphar, is a major pest of pome and stone fruit. Our objective was to determine virulence and reproductive potential of six commercially available nematode species in C. nenuphar larvae and adults. Nematodes tested were Heterorhabditis bacteriophora (Hb strain), H. marelatus (Point Reyes strains), H. megidis (UK211 strain), Steinernema riobrave (355 strain), S...
