Abstract:
... The chemical basis of host selection in stenophagous insects, Oidaematophorus monodactylus, Metriona bicolor, Deloyala guttata and Chelymorpha cassidea was studied. A compound with the molecular formula C₅H₃NO₄, isolated from a water extract of Calystegia sepium, acted as a recognition factor for O. monodactylus and D. guttata but not for M. bicolor and C. cassidea, indicating that insects feeding ...

Abstract:
... In laboratory and garden experiments, we tested for the existence of adaptive patterns of oviposition and larval behaviour regarding group size in the gregarious tortoise beetle Chelymorpha varians Blanchard (Coleoptera: Chrysomelidae: Cassidinae) on its host plant Calystegia sepium L. (Convolvulaceae). Specifically, we addressed the following questions: (i) Which is the more frequent egg cluster ...

Abstract:
... Bois noir is an important grapevine yellows disease in Europe that can cause serious economic losses in grapevine production. It is caused by stolbur phytoplasma strains of the taxonomic group 16Sr-XII-A. Hyalesthes obsoletus Signoret (Hemiptera: Cixiidae) is the most important vector of bois noir in Europe. This polyphagous planthopper is assumed to mainly use stinging nettle [Urtica dioica L. (U ...
