digestive amylase and glucosidases in the larval stage of elm leaf beetle, xanthogaleruca luteola (col.: chrysomelidae)
elm leaf beetle, xanthogaleruca luteola, is a serious pest (particularly at its larval stage) of elm trees in many areas. the existence of three important enzyms namely: ?-amylase, ?- glucosidase and ?-glucosidase in the midgut of the insect at its larval stage was investigated. optimum activity for ?-, ?-glucosidase and ?-amylase was recorded at phs 5.0, 6.0 and 6.0 against p-nitrophenyl-?-d-g...

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 کاملActivity of entomopathogenic nematodes (Rhabditida) against cereal leaf beetle (Oulema melanopus [L.], Coleoptera, Chrysomelidae) adults under laboratory conditions
In 2009, three Slovenian strains of entomopathogenic nematodes) and commercial product Entonem (active ingredient S. feltiae), were tested under laboratory conditions for their activity against adult cereal leaf beetles (Oulema melanopus). The nematode strains were tested at four different doses (250, 500, 1000, and 2000 infective juveniles/adult) and at three temperatures (15, 20, and 25 oC). ...
