The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This pest is often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on the sexual communication system of codling moth, as male and female moths will persist in their attempt ...

Abstract The health and productivity of black walnut (Juglans nigra L.) is currently threatened by Thousand Cankers Disease (TCD), a pest complex comprised an insect vector, the twig beetle (WTB) (Pityophthorus juglandis Blackman) (Coleoptera: Curculionidae), associated pathogenic fungi (Geosmithia morbida Kolařík, Freeland, Utley, Tisserat) (Hypocreales: Bionectriaceae). There urgent need for ...

Small walnut aphid (Chromaphis juglandicola (Kaltenbach) (Hemiptera: Aphididae) is important pest in orchards Lake Van Basin, Turkey. In this study, the life-table parameters reflecting population growth rate and predation of Chrysoperla carnea (Stephen) (Neuroptera: Chrysopidae), which one predators pest, were determined. Life table estimated according to age-stage, two-sex life method. Varian...

continued on page 4 The term allelopathy was first introduced in 1937 and refers to biochemical interactions among plants that alters plant growth, including those mediated by microorganisms. Allelopathy, besides including competition for resources among plants, is considered to be an important mechanism of plant interference caused by the addition of plant-produced toxins to the plant environm...

Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae), an invasive phloem-feeding pest, was identified as the cause of widespread ash (Fraxinus) mortality in southeast Michigan and Windsor, Ontario, Canada, in 2002. A. planipennis reportedly colonizes other genera in its native range in Asia, including Ulmus L., Juglans L., and Pterocarya Kunth. Attacks on nonash species h...

The walnut twig beetle, Pityophthorus juglandis Blackman, and associated fungus Geosmithia morbida Kolařík, Freeland, Utley, & Tisserat constitute the insect-fungal complex that causes thousand cankers disease in walnut, Juglans spp., and wingnut, Pterocarya spp. Thousand cankers disease is responsible for the decline of Juglans species throughout the western United States and more recently, th...

The larval attractant kairomonc, ethyl (2E. 4Z)-2,4-decadienoate or pear ester (PE), was tested in a Californian walnut orchard for its control efficacy against codling moth larvae, Cydia pomonella (L.) (Lepidoptera: Tortricidae) in a microencapsulated bait spray formulation (PE-MEC) combined with various insecticides (choropyrifos, phosmet, methoxyfenozide and a granulosis virus, Cyd-X). PE-ME...
