ABSTRACT- Elm leaf beetle (ELB), Xanthoga leruca luteola (Muller), is considered as one of the most important and destructive phytophagous pests of Ulmus species in the north of Iran. In the current study, the effects of three host plants including Ulmus carpinifolia, U. carpinifolia var. umbraculifera, and Zelkova carpinifolia, on feeding indices and biochemical processes of ELB were examined ...

the objective of the present study was to optimize awettable powder formulation for twoiranianbtstrains (yd5 and kh4) in order to enhance efficiency and durability as biological agent against lepidopteran and coleopteran pests.mass production of the mentioned strains was done in a batch fermentor based on the peviouselyoptimized economical medium and fermentation conditions, and the final conce...

The striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae), is a key pest of cucurbit crops throughout its range. A novel precision band applicator was designed to inject a solid stream of imidacloprid solution in-furrow directly over the seed during planting to reduce beetle leaf feeding on pumpkin, zucchini, and cucumber crops. In 2004 and 2005, bioassays at the cotyledon...

Abstract Background The elm leaf beetle (ELB), Xanthogaleruca luteola Muller (Coleoptera: Chrysomelidae), is one of the most important insect pests that cause damage and physiological stress for trees. In present research, pathogenicity both entomopathogenic fungi (EPF), Beauveria bassiana Metarhizium anisopliae on 1st, 2nd, 3rd instar larval ELB at concentrations 10 5 , 6 7 8 conidia per ml, u...
