Life-Cycle Synchronization in Chrysolina aurichalcea (Coleoptera: Chrysomelidae) to Its Host Artemisia princeps : Effects of Host-Leaf Age on Survival

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

Host plant selection of Chrysolina clathrata (Coleoptera: Chrysomelidae) from Mpumalanga, South Africa

Hyperaccumulated elements such as Ni may defend plants against some natural enemies whereas other enemies may circumvent this defense. The Ni hyperaccumulator Berkheya coddii Roessler (Asteraceae) is a host plant species for Chrysolina clathrata (Clark), which suffers no apparent harm by consuming its leaf tissue. Beetle specimens collected from B. coddii had a whole body Ni concentration of 26...

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 ...

New contributions to the molecular systematics and the evolution of host-plant associations in the genus Chrysolina (Coleoptera, Chrysomelidae, Chrysomelinae)

The taxonomic circumscription of the large and diverse leaf beetle genus Chrysolina Motschulsky is not clear, and its discrimination from the closely related genus Oreina Chevrolat has classically been controversial. In addition, the subgeneric arrangement of the species is unstable, and proposals segregating Chrysolina species into new genera have been recently suggested. In this context, the ...

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...
