Attachment of Galerucella nymphaeae (Coleoptera, Chrysomelidae) to surfaces with different surface energy.
Numerous studies deal with insect attachment onto surfaces with different roughness; however, little is known about insect attachment onto surfaces that have different chemistry. In the present study, we describe the attachment structures of the water-lily leaf beetle Galerucella nymphaeae and test the hypothesis that the larval and adult stages generate the strongest attachment on surfaces wit...
متن کاملCytogenetics, cytotaxonomy and chromosomal evolution of Chrysomelinae revisited (Coleoptera, Chrysomelidae) *
Nearly 260 taxa and chromosomal races of subfamily Chrysomelinae have been chromosomally analyzed showing a wide range of diploid numbers from 2n = 12 to 2n = 50, and four types of male sex-chromosome systems. with the parachute-like ones Xy(p) and XY(p) clearly prevailing (79.0%), but with the XO well represented too (19.75%). The modal haploid number for chrysomelines is n = 12 (34.2%) althou...
متن کاملTimarcha latreille (Coleoptera: Chrysomelidae, Chrysomelinae)
The leaf-beetle genus Timarcha Latreille comprises about four subgenera, 125 species and 30 subspecies, spread in eastern North America and around the Mediterranean basin. They are absent from Syria, Lebanon, Israel, and Egypt, where very probably European and African species once met, but were eradicated during the Pleistocene desertification. In Libya, it survives along the coast on the weste...
متن کاملA chromosomal analysis of three species of Timarcha (Coleoptera, Chrysomelidae, Chrysomelinae)
The karyotypes of three species of Timarcha Latreille, 1829 have been analysed. Timarcha (Metallotimarcha) metallica (Laicharting, 1781), has 18 + Xyp male meioformula and 2n = 38 chromosomes, similar to those found in the two species of subgenus Americanotimarcha Jolivet, 1948, in agreement with morphological and molecular phylogenetic grounds. Timarcha (Timarcha) carmelenae Petitpierre, 2013 ...
متن کاملA chromosomal analysis of four species of Chilean Chrysomelinae (Coleoptera, Chrysomelidae)
Four species of Chilean leaf beetles in the subfamily Chrysomelinae have been cytogenetically analyzed, Blaptea elguetai Petitpierre, 2011, Henicotherus porteri Bréthes, 1929 and Jolivetia obscura (Philippi, 1864) show 2n = 28 chromosomes and a 13 + Xyp male meioformula, and Pataya nitida (Philippi, 1864) has the highest number of 2n = 38 chromosomes. The karyotype of Henicotherus porteri is ma...
