متن کاملTaxonomic remarks, phylogeny and evolutionary notes on the leaf beetle species belonging to the Cryptocephalus sericeus complex (Coleoptera: Chrysomelidae: Cryptocephalinae).
A cladistic analysis was carried out for a complex of 33 species of the genus Cryptocephalus that has been recognized for some time as monophyletic. 55 morphological adult characters have been used, with 119 character states. Analyses were performed using parsimony procedures as well as Bayesian inference. Further information about phylogenetic scenarios were obtained by combining the morpholog...
متن کاملLeaf beetle attachment on wrinkles: isotropic friction on anisotropic surfaces.
The influence of surface roughness on the attachment ability of insects has been repeatedly reported. In previous experiments, complex surface topographies were used as test substrates, whereas periodical structures have so far been neglected. In the present study, traction experiments with adult beetles Gastrophysa viridula and Leptinotarsa decemlineata were carried out to study the influence ...
متن کاملConfirmation of bean leaf beetle, Cerotoma trifurcata, feeding on cucurbits
The objective of these studies was to assess the degree to which bean leaf beetle, Cerotoma trifurcata (Forster), will feed on cucurbits. In 2003, we documented an infestation of C. trifurcata in a commercial pumpkin field near Rosemount, MN, USA. To evaluate C. trifurcata feeding on cucurbits, we conducted laboratory no-choice and choice test feeding studies. In the laboratory, C. trifurcata f...
متن کاملLeaf senescence and clonal growth of white clover
Leaf senescence is a programmed event where resources are mobilised from older tissues to the meristematic regions of the plant. In white clover (Trifolium repens L.), leaf and stolon senescence have an important impact on the persistence of the legume in pasture. As part of our investigation of leaf senescence, we have evidence for a central role for the plant hormone ethylene and have identif...
