A Comparison of Radiographic and Bark-Removal Methods for Sampling of Mountain Pine Beetle Populations (Classic Reprint) - Brossura
Sinossi
Excerpt from A Comparison of Radiographic and Bark-Removal Methods for Sampling of Mountain Pine Beetle Populations
Unlike larvae of the western and southern pine beetles, mountain pine beetle larvae in the thin bark of lodgepole pine feed and pupate primarily in the phloem layer against the sapwood surface. Consequently, removal of bark samples for radiographing would also expose larvae for direct counting. Therefore, any advantage of using the radiographic method in the field would be in the accuracy and speed of sampling beetles in situ. Radiographic sampling has been shown to give accurate counts of mountain pine beetles in bark and wood slabs of lodgepole pine in the laboratory (amman and Rasmussen 1969)

Valutazione del venditore 4 su 5 stelle
Paperback. Condizione: New. Print on Demand. This book contributes to the scientific knowledge on how to best study and sample populations of mountain pine beetles, a notorious species that attacks and kills pine trees. The author meticulously compares two well established methods: radiography (X-ray imaging) and bark removal. Findings suggest that both approaches offer comparable results. However, the radiographic method is found to be more costly, time consuming, and less effective in determining the causes of beetle mortality. Additionally, it negatively impacts beetle populations in sampled areas, which can distort research outcomes. The book underscores the importance of selecting the most appropriate sampling method based on specific research objectives and resource limitations. It also highlights the need for continued advancements in entomological techniques to improve the accuracy and efficiency of insect population studies. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
