Metabolites of Lesser Grain Borer in Grains

Journal of Agricultural and Food Chemistry, 2004
Many volatile alcohol and ester metabolites of the lesser grain borer (LGB, Rhyzopertha dominica) cultured on wheat grain were identified. Volatiles from infested samples at 80 degrees C were collected on Tenax absorbent, thermally desorbed, and analyzed by gas chromatography (GC) using infrared (IR) and mass (MS) detectors for component identification.

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

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, 1985

Insecticide and Acaricide Tests, 1986
Abstract Insecticide-treated and untreated grain sorghum seed were planted in Pike Co, GA on 18 Jun. The test was arranged as a randomized complete block experimental design with 4 replicates. The soil type was a Cecil clay loam. All plots were planted with a 2-row cone-type small plot planter (double-disk opener, press wheel, 32-inch ...

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.

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
