The Genome of Rhyzopertha dominica (Fab.) (Coleoptera: Bostrichidae): Adaptation for Success

open access: yesGenes, 2022
The lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), is a major global pest of cereal grains. Infestations are difficult to control as larvae feed inside grain kernels, and many populations are resistant to both contact insecticides and fumigants. We sequenced the genome of R.

Susceptibility of Rhyzopertha dominica to ionizing radiation

Journal of Stored Products Research, 1974
The effects of ionizing radiation doses between 1 and 20 krad on all stages of Rhyzopertha dominica were studied. Adult emergence from treated eggs and larvae was prevented by 4 and 8 krad respectively. Doses up to 20 krad to pupae only slightly reduced the emergence of adults.

Efficacy of ozone against Rhyzopertha dominica adults in wheat

Journal of Stored Products Research, 2017
Abstract Adults of a laboratory strain of the lesser grain borer, Rhyzopertha dominica (F.), were exposed to ozone concentrations of 0.42 and 0.84 g/m3 for up to 36 and 30 h, respectively, to estimate lethal time (LT) and lethal dose (LD) to kill 99% of insects at 28 °C and 65% r.h. After exposure, adult mortality was counted daily for 5 d.

Proteomic evaluation of adults of Rhyzopertha dominica resistant to phosphine

Environmental Toxicology and Pharmacology, 2008
A proteomic study using a PH(3)-susceptible (RD2) and -resistant strain (CRD343) of Rhyzopertha dominica was undertaken to validate the relation between change of proteins and PH(3) resistance. Protein expression levels were compared using PD-Quest program after two-dimensional polyacrylamide gel-electrophoresis. Comparing the intensity of proteins, 15

Microsatellite markers for Rhyzopertha dominica (Coleoptera: Bostrichidae)

Journal of Stored Products Research, 2016
Rhyzopertha dominica (F.) is a destructive insect pest of stored products. Due to this pest's broad host range, short life cycle, and high reproductive capacity, it has rapidly spread throughout the world. Understanding the population structuring of this important pest is vital for developing and implementing an effective integrated pest management ...

Toxicity and Sublethal Effects of Phthalides Analogs to Rhyzopertha dominica

Chemistry & Biodiversity, 2019
AbstractPhthalides and their precursors have demonstrated a large variety of biological activities. Eighteen phthalides were synthesized and tested on the stored grain pest Rhyzopertha dominica. In the screening bioassay, compounds rac‐(2R,2aS,4R,4aS,6aR,6bS,7R)‐7‐bromohexahydro‐2,4‐methano‐1,6‐dioxacyclopenta[cd]pentalen‐5(2H)‐one (15) and rac‐(3R,3aR,

Respiration of Rhyzopertha dominica (F.) at reduced oxygen concentrations

Journal of Stored Products Research, 2004
Abstract Developmental stages of Rhyzopertha dominica were exposed to atmospheres containing 1%, 2%, 3%, 5%, 10% or 15% oxygen (O2) in nitrogen at 30°C and 70% r.h. Respiration rates were determined with a gas chromatograph. The O2 intake and carbon dioxide (CO2) output by insects were expressed in μl/insect h or μl/mg h.
