Reproduction of phosphine resistant Rhyzopertha dominica (F.) following sublethal exposure to phosphine

Journal of Stored Products Research, 2012
Phosphine fumigation is commonly used to disinfest grain of insect pests. In fumigations which allow insect survival the question of whether sublethal exposure to phosphine affects reproduction is important for predicting population recovery and the spread of resistance.

Phosphine Resistance in the Philippines

The Philippine Entomologist - Volume 32 Issue 2, 2018
Resistance to phosphine is a threat to its continued use as a grain fumigant. Reports of increasing frequency of fumigation failures in the industry make it necessary to look into the possible development of phosphine resistance in major stored product pests.

Russia overtook insect resistance to phosphine.

Khleboproducty, 2020
For the first time, increased resistance to phosphine in the wild population of rice weevil Sitophilus oryzae in Russia has been reported compared to the beetles of laboratory population with a resistance factor of 2.5.

New Tools for Management of Phosphine Resistance

Outlooks on Pest Management, 2006
Phosphine is the primary fumigant used to protect the majority of the world' s grain and a variety of other stored commodities from insect pests. Phosphine is playing an increasingly important role in the protection of commodities for two primary reasons.

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

Do Phosphine Resistance Genes Influence Movement and Dispersal Under Starvation?

Journal of Economic Entomology, 2013
Phosphine resistance alleles might be expected to negatively affect energy demanding activities such as walking and flying, because of the inverse relationship between phosphine resistance and respiration. We used an activity monitoring system to quantify walking of Rhyzopertha dominica (F.) and a flight chamber to estimate their propensity for flight ...

Effects of time and concentration on mortality of phosphine‐resistant Sitophilus oryzae (L) fumigated with phosphine

Pest Management Science, 2002
Abstract The effects of exposure period and phosphine concentration on mortality of susceptible and resistant Sitophilus oryzae (L) were investigated. Although S oryzae is one of the world's most serious pests of stored grain there are

Inheritance of Phosphine Resistance in Tribolium castaneum (Coleoptera: Tenebrionidae)

Journal of Economic Entomology, 1999
The genetics of phosphine resistance was studied in a resistant strain of the red flour beetle, Tribolium castaneum (Herbst), developed from field collections in Queensland, Australia. A program of inbreeding and selection was maintained for 5 generations to promote homozygosity in this strain and a laboratory-susceptible strain. The strain was then 12.

Phosphine Resistance in Psocid, Liposcelis bostrychophila (Psocoptera) in the Philippines

International Journal of Tropical Insect Science, 2020
Phosphine fumigation is one of the most effective way control insect pests in stored agricultural products. However, continuous use and highly dependent on phosphine fumigation has led to resistance development of major storage insect pests, including psocid.

Utilizing low oxygen to mitigate resistance of stored product insects to phosphine

Journal of the Science of Food and Agriculture, 2022
AbstractBACKGROUNDData are provided on the utilization of modified atmospheres, at a commercial scale, against stored product insect populations that are resistant to phosphine. The method is evaluated on different populations of two major stored‐product beetle species, Rhyzopertha dominica and Oryzaephilus surinamensis.
