Occurrence of Nitidulid Beetles (Coleoptera: Nitidulidae) in Texas Oak Wilt Centers

چکیده
J. Econ. Entomo!. 79: 1276-1279 (1986) ABSTRACT In 1984-85 free-flying nitidulids were trapped in centers of oak wilt, Ceratocystis fagacearum (Bretz) Hunt, for 1 year at six locations in central Texas. Two of the 10 species identified, Cryptarcha concinna Melsheimer and Coiopterus maculatus (Erichson), accounted for 57 and 35%, respectively, of the total number (3,397) of beetles trapped. Peak nitidulid activity occurred during March-May at all sites. Beetles exhibited some preference for tree location within a trapping site, visiting healthy live oaks, Quercus fusiformis Small, in greater numbers than dead Spanish oaks, Quercus texana Buckley.

Acquisition of Ophiostoma quercus and Ceratocystis fagacearum by Nitidulids from O. quercus–Colonized Oak Wilt Mats
Oak wilt infection centers are initiated by overland spread of the causal fungus, Ceratocystis fagacearum (T. W. Bretz) J. Hunt, by insects (10). Sap-feeding beetles (Coleoptera: Nitidulidae) are considered a primary vector of the pathogen in the north central states (7,9). Successful transmission by sap-feeding beetles depends on several coexisting conditions, including (i) the availability of...
متن کاملThe Genus Ceratocystis : Where Does the Oak Wilt Fungus Fit ?
Most species of Ceratocystis are plant pathogens, primarily colonizing sapwood near wounds on woody hosts, but only C. fagacearum causes a true vascular wilt. All species produce sexual spores in a sticky mass for insect dispersal, and most species, including C. fagacearum, produce fruity volatiles that are attractive to insects. Many Ceratocystis species produce sporulation mats on exposed woo...

متن کاملTrophic habits of Aethina tumida (Coleoptera: Nitidulidae): their adaptive significance and relevance to dispersal.
Aethina tumida Murray is an African native that has become an important pest of honey bee colonies in North America and Australia. Adults and larvae feed on pollen, honey, and brood in bee hives. The beetle is also able to feed and reproduce on fresh or rotting fruit, but natural occurrence on this diet has rarely been observed. We compared the reproductive success-as measured by progeny produc...
