Endemism patterns in the Italian leaf beetle fauna (Coleoptera, Chrysomelidae)
In this contribution the results of a zoogeographical analysis, carried out on the 123 endemic leaf beetle species (Coleoptera: Chrysomelidae) occurring in Italy and its immediately adjacent regions, are reported. To assess the level of faunistic similarity among the different geographic regions studied, a cluster analysis was performed, based on the endemic component. This was done by calculat...
متن کاملPHYSIOLOGICAL ECOLOGY Effects of Cottonwood Leaf Beetle (Coleoptera: Chrysomelidae) Larval Defoliation, Clone, and Season on Populus Foliar Phagostimulants
The cottonwood leaf beetle, Chrysomela scripta F., is a serious defoliator of plantation Populus in the United States. Current control methods include biorational and synthetic chemicals as well as selecting Populus clones resistant or tolerant to C. scripta defoliation. SpeciÞc ratios of long-chain fatty alcohols to alpha-tocopherylquinone ( -TQ) on the leaf surface of Populus spp. act as phag...
متن کاملThe effects of host plants on the feeding indices and chemical activities of elm leaf beetle, Xanthogaleruca luteola (Muller) (Coleoptera: Chrysomelidae)
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 ...
متن کاملFormulatio& Novodor and Raven, for Control of Cottonwood Leaf Beetle (Coleoptera: Chrysomelidae)
Laboratory and field experiments were conducted to determine the efficacy of two t~uring&x.sis Berliner formulations, Novodor and Raven, for controlling cottonwood leaf beetle, Cluysomekz scripta F. (Coleoptera: Chrysomelidae) . In laboratory bioassays, larvae or adults were added to petri dishes containing Pop&s X euramericunu Guinier ‘Eugenei’ foliage that had been treated with distilled wate...
متن کاملLocomotion and attachment of leaf beetle larvae Gastrophysa viridula (Coleoptera, Chrysomelidae).
While adult green dock leaf beetles Gastrophysa viridula use tarsal adhesive setae to attach to and walk on smooth vertical surfaces and ceilings, larvae apply different devices for similar purposes: pretarsal adhesive pads on thoracic legs and a retractable pygopod at the 10th abdominal segment. Both are soft smooth structures and capable of wet adhesion. We studied attachment ability of diffe...
