Can. EW. 112: 515-519 (1980) In southern Louisiana, Corticeus glaber (LeConte) outnumbered Corticeus parallelus (Melsheimer) 3.7:l during 15-month study from October 1976 to December 1977. Corticeus spp. varied significantly (P < 0.01) among the 52 sample dates and three sample heights on infested tree boles. Corticeus spp. were significantly correlated with numbers of southern pine beetle eggs, Dendroctonus frontalis Zimmermann, in the bottom and middle samples but not in the top sample.doi:10.4039/ent1125-2 fatcat:fqhnukhgpraaxazp3speotu5jq
