Explanation of Names
Carpophilus sayi Parsons, 1943
sayi = named after
Thomas Say, a prominent American entomologist and naturalist of the early 19th century
Range
e. NA (NS-SK to GA-TX-NM)
(2)(3)Season
more abundant in oak wilt mats in the spring than in the fall
(4)Life Cycle
Vector of the oak wilt fungus, Ceratocystis fagacearum (Bartelt et al. 2004)
Remarks
Carpophilus sayi and Colopterus truncatus are the predominant species collected from fresh wounds on red oak in Minnesota (Juzwik et al. 1999), suggesting these are the primary vectors in MN. (Cervenka et al. 2001) C. sayi was not indicated as possible vector in Missouri or Texas. (Hayslett et al. 2008)
