| 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 ( ... | 2007 | 17716465 |
| bacteria from ips sexdentatus (coleoptera: curculionidae) and their biocontrol potential. | ips sexdentatus (coleoptera: curculionidae) is one of the most destructive pests of the spruce trees in europe. in this study, we have isolated and characterized culturable bacteria from i. sexdentatus and tested their insecticidal activity against the last instar larvae of the pest as a possible biocontrol agent. a total of eight bacterial isolates was determined and four of them were identified at species level, and the others were identified at genus level. isolates were identified as stenotr ... | 2012 | 22581609 |
| metschnikowia cf. typographi and other pathogens from the bark beetle ips sexdentatus - prevalence, histological and ultrastructural evidence, and molecular characterization. | ips sexdentatus (six-spined engraver beetle) from austria and poland were dissected and examined for the presence of pathogens. specimens collected in austria were found to contain the ascomycetous fungus metschnikowia cf. typographi. infection rates ranged from 3.6% to 26.8% at different collection sites. m. cf. typographi infected midguts were investigated by histological, ultrastructural and molecular techniques. extraordinary ultrastructural details are shown, such as ascospores with bilater ... | 2017 | 27914926 |
| [weight variations of adipose tissue and ovaries and variations in the length of ovocytes in ips sexdentatus boern (coleoptera: scolytidae); relation to parasitism by nematodes]. | the variations of the weight of the fat body and the ovaries, as well as the length of the maturest oocyte, have been studied in ips sexdentatus, from the end of the maturation of pre-swarming to the 24th hour after the copulation. in the healthy insects, the weight of the ovaries and the size of the terminal oocyte grow till the swarming, but decline slightly at the 3rd hour after the copulation; the growth recovers afterwards, at first slow, then very steep after the 12th hour. the fat body de ... | 1982 | 7187205 |
