Prey specificity of adultTemnochila virescensF. (Col., Trogositidae), a predator ofIps grandicollisEichh. (Col., Scolytidae)

Autor: S. A. Lawson, F. D. Morgan

Publikováno v: Journal of Applied Entomology. 115:139-144

Temnochila virescens, a bark beetle predator from the southeastern USA, was imported into Australia in 1981 as part of a biological control program for Ips grandicollis, the five-spined engraver beetle. To meet quarantine requirements, studies were c

Rearing of two predators, Thanasimus dubius and Temnochila virescens, for the biological control of Ips grandicollis in Australia

Autor: F. D. Morgan, Simon A. Lawson

Publikováno v: Entomologia Experimentalis et Applicata. 65:225-233

Rearing methods for two coleopterous predators, Thanasimus dubius and Temnochila virescens, imported into Australia for the biological control of Ips grandicollis, were developed. Bionomic data obtained from laboratory rearings between 1982–1987 sh

Comparison of four least‐squares inversion schemes for studying equivalence in one‐dimensional resistivity interpretation

Autor: J. E. Simms, F. D. Morgan

Publikováno v: GEOPHYSICS. 57:1282-1293

The problem of equivalence in dc resistivity inversion is well known. The ability to invert resistivity data successfully depends on the uniqueness of the model as well as the robustness of the inversion algorithm. To study the problems of model uniq

Stability factors of Darlington transistors†

Autor: F. D. Morgan, L. N. S. Kunar

Publikováno v: International Journal of Electronics. 57:491-497

Expressions giving the change in quiescent collector current due to variations in collector reverse saturation current. and base-emitter voltage have previously been derived for the Darlington composite transistor. In this paper these expressions arc

An instrument system for low-frequency (10−3–103 Hz) impedance measurements

Autor: Brian R. Bennett, T. R. Madden, F. D. Morgan

Publikováno v: IEEE Transactions on Instrumentation and Measurement. :287-292

An instrument system is presented for impedance measurements in the frequency range 10-3-103 Hz. The instrument features a three-frequency sinusoidal source with digital data acquisition. The former shortens the experimental duration whereas the latt

Behaviour of the bark beetle, Ips grandicollis, during host selection

Autor: Jayanthi P. Witanachchi, F. D. Morgan

Publikováno v: Physiological Entomology. 6:219-223

Equal numbers of dispersing Ips grandicollis adults were caught on sticky traps held on susceptible and resistant Pinus radiata trees. When beetles were attracted to the same set of trees using baits of ipsenol (aggregation pheromone), some of the be
