Fluorescent Pigments for Marking Lesser Grain Borers (Coleoptera: Bostrichidae)

Journal of Economic Entomology, 1992
Fluorescent dyed melamine copolymer resins were evaluated to determine their effectiveness for marking adult Rhyzopertha dominica to be used in release-recapture experiments. Pigments were retained very well, and marked individuals were easily identified under longwave ultraviolet light up to 21 d after treatment. Little pigment was transferred between

Rhyzopertha dominica (lesser grain borer).

2021
Abstract Females of R. dominica lay between 200 and 500 eggs in their lifetime. The eggs are laid loose in grain. The lowest temperature at which R. dominica can complete development is 20°C; at this temperature, the development from egg to adult takes 90 days.

Oogenesis in the lesser grain borer, Rhizopertha dominica(Fabricius) (Coleoptera : Bostrichidae)

International Journal of Insect Morphology and Embryology, 1992
Abstract The morphology and ultrastructure of ovarioles in Rhizopertha dominica (Coleoptera : Bostrichidae) are described. Ovarioles are of telotrophic type and are composed of an apical terminal filament, trophic chamber, and vitellarium. The trophic chamber consists of numerous individual trophocytes that remain connected by intercellular bridges.

Lesser Cornstalk Borer Control in Grain Sorghum, 1983

Insecticide and Acaricide Tests, 1986
Abstract Two experiments were planted (36-inch rows) on 31 Aug (Test l)and 20 Sep (Test 2) in Spalding Co, GA. The soil type was a Cecil loamy clay soil. Materials were applied 2 days after each planting in randomized complete blocks with 4 replicates.

Food Specialization of the Lesser Grain Borer, Rhyzopertha Dominica F. (Coleoptera: Bostrichidae)

Canadian Journal of Agriculture and Crops, 2020
Observations of stored grain, products from its manufacture and materials from plant origin in the storage-silo bases in Bulgaria were conducted from 1990 till 2019 to establish the food specialization and trophic chains of Rhyzopertha dominica F. The insect was found mostly in wheat grain – 49,2% from all expected samples, followed by barley – 18,5 ...

Lesser Cornstalk Borer Control in Grain Sorghum, 1984

Insecticide and Acaricide Tests, 1986
Abstract Insecticide-treated and untreated sorghum seed were planted (32-inch row spacing) on 24 Aug in Spalding Co, GA. The test was arranged in a randomized complete block experimental design with 4 replicates. The soil type was a Cecil loamy clay.

Mitochondrial response of the lesser grain borer Rhyzopertha dominica (F.) to modified atmospheres

Journal of Stored Products Research, 2019
Abstract Rhyzopertha dominica is an insect pest that feeds on a wide variety of grains and stored cereals, producing economical losses. Bioenergetics studies on insects are necessary to eventually plan strategies to reduce pest infestation on stored grains with methods other than insecticides. Modified atmosphere treatments, where insects are exposed

Feeding preference and development of lesser grain borer, Rhyzopertha dominica (Fabricius) in different millet grains

Journal of Entomological Research
AbstractInvestigations were carried out to assess the feeding preference and development of Rhyzopertha dominica on seven different millets. Results inferred that more feeding preference was towards sorghum (33.33 adults) followed by barnyard millet (25.67 adults) whereas remaining tested millets had less attraction for the pest.

Effect of Infestation by the Larger Grain Borer, Prostephanus truncatus (Horn), and the Lesser Grain Borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), on Stored Corn

Environmental Entomology, 1987
The quantitative and qualitative losses in stored corn infested by Prostephanus truncatus (Horn), and stored for 20 wk at 30°C and 70% RH, were compared with those of Rhyzopertha dominica (F.). Treatments included insect-infested whole corn, uninfested whole corn plus ground corn (dockage), and uninfested whole corn.
