Effects of feeding experience on feeding responses to spinach in Cassida nebulosa L. (Coleoptera: Chrysomelidae)

Factors Determining the Host Range of Two Tortoise Beetles, Cassida nebulosa L. and C. piperata Hope (Coleoptera: Chrysomelidae) in Japan

We investigated the relationship between host-plant use by two tortoise beetles, Cassida nebulosa and C. piperata, in a field and their performance under laboratory conditions. Sixteen plant species were grown in the experimental field with C. nebulosa being observed to grow on three chenopodiaceous species (Chenopodium album, C. album var. centrorubrum, and C. ficifolium), while C. piperata gr...

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

Description of larvae of two closely related species Cassida palaestina Reiche, 1858 and Cassida rubiginosa Müller, 1776 (Coleoptera: Chrysomelidae: Cassidinae).

Larvae of two closely related species Cassida palaestina Reiche, 1858 and Cassida rubiginosa Müller, 1776 are described in detail including SEM microstructures. First instars are extremely similar with no clear diagnostic characters, larvae of Cassida palaestina are slightly more contrastingly coloured than larvae of C. rubiginosa, the latter having darker scoli, basal part of supra-anal proces...

Susceptibility of brassicaceous plants to feeding by flea beetles, Phyllotreta spp. (Coleoptera: Chrysomelidae).

Crucifer-feeding flea beetles, Phyllotreta spp., are chronic insect pests in Canadian prairie canola production. Multiple laboratory and field feeding bioassays were conducted to determine the susceptibility of a wide range of crucifer species, cultivars, and accessions to feeding by flea beetles with the goal of discovering sources of resistant germplasm. In 62 bioassays of 218 entries, no con...
