چکیده
Ann. Entomol. Soc. Am. 76: 400-402 (1983) ABSTRACT No males were found among 559 specimens of Pityophthorus puberulus (LeConte) from several localities. No sperm was found in the spermatheca of 10 females taken from recently established galleries containing eggs and young larvae. This is the third record of thelytoky in a scolytid. The known distribution and environment of parthenogenetic populations of P. puberulus does not fit the usual patterns of distribution and environmental situations associated with parthenogenetic animals.

Twig beetles in the genus Pityophthorus Eichhoff, 1864 include more than 300 species worldwide, with maximum diversity in tropical and subtropical regions. To date, approximately 50 species of Pityophthorus have been recorded in Canada, and these species are associated mainly with coniferous trees. Since 1981, no comprehensive study on this difficult taxonomic group has been conducted in Quebec...

Twig beetles in the genus Pityophthorus Eichhoff are known to be associated with the pitch canker pathogen, Fusarium circinatum, in California. Phoresy of the pathogen on these species has been reported to occur when insects emerge from diseased branches and when they infest disease-free, cut branch tips. To demonstrate that twig beetles can vector the pathogen, studies of phoresy and transmiss...

Pitch canker of pines (Pinus spp.) and Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) (Pinaceae) is caused by the fungus Fusarium circinatum Nirenberg et O’Donnell. In California, infections by F. circinatum occur largely through wounds caused by insects. Field experiments were initiated to determine whether the colonization activities of twig beetles, Pityophthorus spp. (Coleoptera: Scoly...
