quantitative association of bark beetles with pitch canker fungus and effects of verbenone on their semiochemical communication in monterey pine forests in northern spain.the association between 11 species of bark beetles (coleoptera: scolytinae) and one weevil (coleoptera: entiminae) with the pitch canker fungus, fusarium circinatum nirenberg and o'donnell, was determined by crushing beetles on selective medium and histone h3 gene sequencing. pityophthorus pubescens (marsham) (25.00%), hylurgops palliatus (gyllenhal) (11.96%), ips sexdentatus (börner) (8.57%), hypothenemus eruditus westwood (7.89%), hylastes attenuatus erichson (7.40%), and orthotomicus erosus ( ...200717716465
karyotypic characterization of three weevil species (coleoptera: curculionidae, brachyderini).karyotypes of three species, brachyderes incanus, brachysomus setiger and paophilus afflatus, belonging to the tribe brachyderini, were studied using c-banding technique. the species share the same chromosome number 2n = 22 and meioformula n = 10+xy(p) at all metaphase 1 plates of spermatid division. some differences between karyotypes were observed in terms of centromere positions and c-band sizes. most chromosomes are meta- or submetacentric and form a graded series in respect to length. the c ...200617044254
karyological investigations on seven weevil species (coleoptera, curculionidae).karyological studies were carried out on seven palaearctic weevils. the following chromosome numbers were found in individual species, i.e. otiorhynchus niger (f.), phyllobius viridearis (laich.), phyllobius scutellaris redt., phyllobius calcaratus (f.), polydrusus cervinus (l.), and brachyderes incanus (l.) 2n = 22, n male = 10 + xyp, in lixus elegantulus (boh.) 2n = 22, n male = 21 + xyp. the heterochromosomes of all the examined species form, in the first meiotic metaphase, a typical parachut ...200011291535
