Laboratory studies on the flight capacity of the Mahogany Shootborer, Hypsipyla grandella (Zeller) (Lepidoptera, Pyralidae)1

Autor: D. R. Geiszler, J. O. Fasoranti, R. I. Gara

Publikováno v: Zeitschrift für Angewandte Entomologie. 93:182-186

The flight capacity of male and female Hypsipla grandella was determined by flight mill and wing beat frequency analyses. Flight velocity and duration of 2 to 4 day old female moths decreased significantly more than that of males. However 1 to 2 day

Impacts of mountain pine beetle (Dendroctonus ponderosae) (Col., Scolytidae) infestation on future landscape susceptibility to the western spruce budworm (Choristoneura occidentalis) (Lep., Tortricidae) in north central Washington

Autor: R. I. Gara, E. S. Isaac, J. S. Wilson

Publikováno v: Journal of Applied Entomology. 122:239-245

Current and future western spruce budworm [Choristoneura occidentalis (Freeman)] hazard was evaluated for a 400 ha (1000 acre) landscape in north central Washington state using computerized growth and hazard-rating models. The landscape has recently
