Effects of host plant quality on overwintering success of the leaf beetle Chrysomela lapponica (Coleoptera: Chrysomelidae)

The 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 ...

nutritional indices of the willow leaf beetle, plagiodera versicolora (coleoptera: chrysomelidae) on different host plants

nutritional indices of the willow leaf beetle, plagiodera versicolora laicharting, third instar larvae and adults were studied on four host plants including salix alba l., salix aegyptica l., populus caspica bornm.and populus alba l.at 22 ± 2 ºc, 70 ± 10% r.h., and a photoperiod of 16:8 h (l: d). the results showed that the highest consumed food by the larvae and adults (148.5 ± 18.0 and 175.21...

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...

Evaluation of feeding response,age specific survival and longevity of poplar leafbeetle chrysomela populi (coleoptera chrysomelidae) on five host plants

Overwintering survival, phenology, voltinism, and reproduction among different populations of the leaf beetle Diorhabda elongata (Coleoptera: Chrysomelidae).

The classical biological control program for exotic saltcedars (various Tamarix species and hybrids) has involved the assessment of different populations of the leaf beetle Diorhabda elongata (Brullé) s.l. that are promising for release in areas of North America that are located south of 37 degrees N latitude. We report here the overwintering survival, phenology, and voltinism of four D. elonga...
