| comparison of four trap types for ambrosia beetles (coleoptera, scolytidae) in brazilian eucalyptus stands. | eucalyptus spp. plantations represent >60% of the reforested area in brazil. although ambrosia beetle attacks on live trees were at first nonexistent, they have begun to appear with greater frequency. monitoring for pest insects is a key factor in integrated pest management, and baited traps are one of the most widely used methods for insect population detection and survey. we compared the efficiency of the most widely used trap in brazil to survey for ambrosia beetles and other scolytidae, the ... | 2000 | 11142301 |
| 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 |
| optimizing ethanol-baited traps for monitoring damaging ambrosia beetles (coleoptera: curculionidae, scolytinae) in ornamental nurseries. | the exotic ambrosia beetles xylosandrus crassiusculus (motschulsky) and xylosandrus germanus (blandford) (coleoptera: curculionidae: scolytinae) are serious pests in ornamental tree nurseries. to optimize bottle-traps as a monitoring system for x. crassiusculus and x. germanus in nurseries, we tested whether increasing the rate of commercial ethanol lures improved captures or early detection of these species. experiments were conducted in ohio (2008 and 2009) and virginia (2008), two states that ... | 2011 | 22299365 |
