Insect Radar Cross-sections for Aerial Density Measurements and Target Classification
Autor: G. M. Loper, W. W. Wolf, C. R. Vaughn, R. Harris
Publikováno v: Transactions of the ASAE. 36:949-954
Radar cross-sections (RCS) of adults of six insect species were measured with a high-resolution radar for selected aspect angles and polarization angles. These data were fit to transcendental equations relating RCS to aspect angle or polarization ang

Olfactory Discrimination by Honeybees of Terpenes Identified from Volatiles of Alfalfa Flowers
Autor: Richard L. Berdel, G. M. Loper, Gordon D. Waller
Publikováno v: Journal of Apicultural Research. 13:191-197
SummaryHoneybees conditioned to respond to the scent of flowers of alfalfa clone 2490 and of sainfoin responded positively to the scents of ocimene, myrcene and limonene, but not to linalool; bees conditioned to the scent of flowers of alfalfa clone

Some Aspects of Flower Biology and Bee Activity on Hybrid Cotton in Arizona, USA
Autor: G. M. Loper, Dan Eisikowitch
Publikováno v: Journal of Apicultural Research. 23:243-248
SummaryThe phenology of flowering of male-fertile and genetic-cytoplasmic male-sterile upland cottons was observed and compared in detail, and a descriptive sequence which identifies 5 stages of an thesis is proposed. Phenological differences as well

A Bioassay for Determining Honey Bee Responses to Flower Volatiles 1
Autor: Richard L. Berdel, G. M. Loper, Gordon D. Waller
Publikováno v: Environmental Entomology. 2:255-259
A test arena was designed for determining the responses of Apis mellifera L. to components of scent gland pheromone and flower volatiles of alfalfa, Medicago sativa L. Bees that had been conditioned to associate the odor of citral, geraniol, ocimene,
