Nitidulid Beetles

Beetles in the family Nitidulidae can transmit the oak wilt fungus, Ceratocystis fagacearum, to fresh wounds on healthy oak trees, leading to infection and disease development. Historically, nitidulid beetles have not been considered important vectors of the pathogen in Missouri. Studies were conducted in the spring of 2005 and 2006 to determine frequencies of nitidulid beetle species contaminated with C. fagacearum visiting fresh wounds on red oak trees in central Missouri. Colopterus truncatus, C. niger, and C. semitectus were the most abundant species collected from fresh wounds and the only species found to be contaminated with Ceratocystis fagacearum. Of 230 beetles assayed for C. fagacearum, 23 yielded the fungus. Contamination frequencies were higher for beetles collected in April than May; no beetles collected in June were contaminated. We hypothesize that Colopterus truncatus, C. niger, and C. semitectus are principal nitidulid beetle vector species in Missouri during spring. The risk for pathogen transmission by these beetles appears to be greatest in April and least in June.

Division Process

Vegetative nuclei of fungi Ceratocystis fagacearum and Fusarium oxysporum were studied both in the living condition with phase-contrast microscopy and after fixation and staining by HCl-Giemsa, aceto-orcein, and acid fuchsin techniques. Nucleoli, chromosomes, centrioles, spindles, and nuclear envelopes were seen in living hyphae of both fungi. The entire division process occurred within an intact nuclear envelope. Spindles were produced between separating daughter centrioles. At metaphase the chromosomes became attached to the spindle at different points. In F. oxysporum the metaphase chromosomes were clear enough to allow counts to be made, and longitudinal splitting of the chromosomes into chromatids was observed. Anaphase was characterized in both fungi by separation of chromosomes to poles established by the centrioles, and in F. oxysporum anaphase separation of chromosomes was observed in vivo. Continued elongation of the spindles further separated the daughter nuclei. Maturing daughter nuclei of both fungi were quite motile; and in C. fagacearum the centriole preceded the bulk of the nucleus during migration. The above observations on living cells were corroborated by observations on fixed and stained material.

Pyrimidine Moiety

The optimum KH2PO4 concentration for perithecium production by Ceratocystis fagacearum in a semi-synthetic agar medium was 7.4 × 10−1 M. A great reduction in the number of perithecia occurred at 0.1 M and none were formed at 0.2 M concentration. The optimum pH was 5.2 and no perithecia formed at pH 7.0. Either exogenous thiamine or its pyrimidine moiety is absolutely essential for perithecium formation. Pyridoxine, inositol and biotin were not required for growth or reproduction. Receptivity of 14-day-old cultures remained high for longer periods when stored at 12 °C than at 3 °C or 21 °C. Of the 17 isolates studied, 14 produced sterile perithecia before conidia were applied experimentally. Attempts to fertilize these were unsuccessful. Perithecia which did not extrude ascospores formed on colonies following application of conidia. In such perithecia, opened ostiolar hyphae did not necessarily indicate sterility. Neither abrasion of colonies, nor brushing with sterile distilled water or with a filtrate of sonic-disrupted condia, increased sterile perithecium production. However, brushing the colonies with an extract of germinated conidia did increase their formation.
