Comparison of Honey Bee (Hymenoptera: Apidae) Mortality as a Result of Diurnal and Nocturnal Applications of Dimethoate

Publikováno v: Journal of Economic Entomology. 83:1267-1270

Applications of dimethoate in Arizona are currently being made to citrus orchards at night to reduce the hazard to pollinating honey bees, Apis mellifera L. Over a 9-d period, an application of dimethoate sprayed during the day produced a mean number

Recovery of learning responses by honeybees following a sublethal exposure to permethrin

Autor: Amed N. Mamood, Gordon D. Waller

Publikováno v: Physiological Entomology. 15:55-60

A classical conditioned response was used to evaluate the learning behaviour of honeybees (Apis mellifera L.) which survived a sublethal dose of permethrin. Treated bees had lower learning response levels than untreated bees for 3 days, but regained

Dispersal of Upland and Pima Cotton Pollen by Honey Bees (Hymenoptera: Apidae) Visiting Upland Male-Sterile Flowers

Autor: James R. Hagler, Amed N. Mamood, Gordon D. Waller

Publikováno v: Environmental Entomology. 19:1034-1036

A field study was conducted in Tucson, Ariz., in 1987 to evaluate the dispersal of cotton ( Gossypium spp.) pollen grains by honey bees, Apis mellifera L., in relation to distance from pollen source and time-of-day. The experimental field consisted o

Upland and Pima Cotton as Pollen Donors for Male‐Sterile Upland Seed Parents

Autor: Gordon D. Waller, Amed N. Mamood

Publikováno v: Crop Science. 31:265-266

The development of an interspecific hybrid cotton has been hampered by a serious problem with pollination. A field study was conducted to compare Pima Cotton (Gossypium barbadense L.) with upland cotton (G. hirsutum L.) as a pollen source for hybrid

Comparison of Carpenter Bees (Xylocopa varipuncta Patton) (Hymenoptera: Anthophoridae) and Honey Bees (Apis mellifera L.) (Hymenoptera: Apidae) as Pollinators of Male-sterile Cotton in Cages1

Autor: Gordon D. Waller, Joseph H. Martin, Bernard E. Vaissière, Joseph O. Moffett

Publikováno v: Journal of Economic Entomology. 78:558-561

Carpenter bees ( Xylocopa varipuncta Patton) compared favorably with honey bees ( Apis mellifera L.) as pollinators of A-line and B-line cotton ( Gossypium hirsutum L.) in field cages. Yields of seed cotton on the A-line plants were not significantly

Honeybee Responses to Sugar Solutions of Different Compositions

Autor: Walter W. Bachman, Gordon D. Waller

Publikováno v: Journal of Apicultural Research. 16:165-169

SummaryHoneybee foragers were caught as they returned to their hive. Each was mounted by the dorsum on a wire, and after 45 minutes was offered two sugar solutions alternately. Bees that made a choice (e.g. imbibing one solution after rejecting the o

Comparison of Honey Bee (Hymenoptera: Apidae) Losses from Two Formulations of Methyl Parathion Applied to Sunflowers

Autor: Jack Harvey, T. L. Archer, Gordon D. Waller, Barbara J. Erickson

Publikováno v: Journal of Economic Entomology. 77:230-233

When blooming sunflowers, Helianthus annuus L., were treated with microencapsulated methyl parathion, nearby colonies showed a mean loss of 460 honey bees, Apis mellifera L. Colonies located near a sunflower field treated with an emulsifiable concent

Use Of Honey-Sac Load and Dance Characteristics of Worker Honeybees to Determine Their Sugar Preferences

Autor: Walter W. Bachman, Gordon D. Waller

Publikováno v: Journal of Apicultural Research. 20:23-27

SummaryFrequency of dancing by returning honeybees (Apis mellifera) was shown to be positively correlated with concentration of sugar solution they had collected. Also, sucrose resulted in more dances than fructose, which in turn led to more dances t
