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 کاملEstablishment of Parasitoids of the Lily Leaf Beetle (Coleoptera: Chrysomelidae) in North America.
Three larval parasitoids were imported from Europe to control the lily leaf beetle, Lilioceris lilii Scopoli (Coleoptera: Chrysomelidae), an accidentally introduced herbivore of native and cultivated lilies in North America. Tetrastichus setifer Thomson (Hymenoptera: Eulophidae) was introduced in Massachusetts in 1999, and was found to be established there in 2002. Subsequent releases of T. set...
متن کاملcharacterization of digestive α-amylase in the midgut of willow leaf beetle plagiodera versicolora (coleoptera: chrysomelidae)
willow leaf beetle, plagiodera versicolora is an important pest of willow trees that feeds on the leaves both as larvae and as adults. -amylases (ec 3.2.1.1) are the major insect digestive enzymes that catalyze the endohydrolysis of long -1,4-glucan chains such as starch and glycogen. in the current study, -amylase activity was studied in the midgut of larvae and adults of p. versicolora. am...
متن کاملExploring the Leaf Beetle Fauna (Coleoptera: Chrysomelidae) of an Ecuadorian Mountain Forest Using DNA Barcoding
BACKGROUND Tropical mountain forests are hotspots of biodiversity hosting a huge but little known diversity of insects that is endangered by habitat destruction and climate change. Therefore, rapid assessment approaches of insect diversity are urgently needed to complement slower traditional taxonomic approaches. We empirically compare different DNA-based species delimitation approaches for a r...
متن کاملVertical stratification of leaf-beetle assemblages (Coleoptera: Chrysomelidae) in two forest types in Panama
To studyvertical gradients of arthropod species richness in tropical forests, adult chrysomelidswere surveyed with similar sampling effort by beating in four plots of 0.8 ha, representative of the canopy and understorey of one wet and one dry forest in Panama. Samples included in total 4615 individuals representing 253 species, and were of similar species richness at the two study sites. At bot...
