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

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.

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.

Modeling and analyzing the dielectric properties of Rhyzopertha dominica (F.)

TENCON 2011 - 2011 IEEE Region 10 Conference, 2011
Dielectric properties of Rhyzopertha dominica (F.), Lesser Grain Borer with frequency range 200MHz–20GHz and Temperature range 24–65°C has been measured by using high temperature probe (Agilent). Measurement temperature points were 18. Then analyze the differentiation of dielectric properties of Rhyzopertha dominica (F.) and Malaysian paddy D219. After

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.

Genetics of resistance to phosphine in Rhyzopertha dominica (Coleoptera: Bostrichidae).

Journal of economic entomology, 2002
The inheritance of resistance to phosphine was studied in two strains of the lesser grain borer, Rhyzopertha dominica (F.), labeled 'Weak-R' and 'Strong-R'. These strains were purified versions of field-selected populations collected in Queensland, Australia.

Movement of Rhyzopertha dominica in response to temperature gradients in stored wheat

Journal of Stored Products Research, 2011
The movement and temperature preference of Rhyzopertha dominica was determined in a 56 cm diameter cylinder with 9 cm high sides containing 19.9 kg of hard red winter wheat. Two temperature gradients were tested over a 24 h period: 42 to 20 C and 24 to 20 C with the cooler temperature being on the periphery of the cylinder.

Purification, characterization and inhibition studies of α-amylase of Rhyzopertha dominica

Pesticide Biochemistry and Physiology, 2010
Abstract Rhyzopertha dominica causes extensive damage to stored wheat grains. α-Amylase, the major insect digestive enzyme, can be an attractive candidate to control the insect damage by inhibiting the enzyme through α-amylase inhibitors. R. dominica α-amylase (RDA) was purified to homogeneity by differential ammonium sulphate fractionation ...
