Inheritance of Phosphine Resistance in Tribolium castaneum (Coleoptera: Tenebrionidae)
Journal of Economic Entomology, 1999The 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.

Rationale Behind the Resistance of Dialkylbiaryl Phosphines toward Oxidation by Molecular Oxygen
Journal of the American Chemical Society, 2007Electron-rich dialkylbiaryl phosphines, which comprise a common class of supporting ligands for Pd-catalyzed cross-coupling reactions, are highly resistant toward oxidation by molecular oxygen. Presented herein are possible reasons why this class of phosphine ligands manifests this property.

AbstractAbstract: The susceptibility of eggs, pupae and adults of Tribolium castaneum (Herbst) and adults of Rhyzopertha dominica (F.), (both phosphine‐resistant strains) to phosphine at fixed concentration‐time (ct) products, with either constant or increasing or decreasing concentrations was studied at 25 (± 1)°C.

Pesticide Resistance to Phosphine and Biotest
2017Rezistentnost štetnika na fumigante predstavlja otpornost jedinki u populaciji štetnika da prežive izloženost letalnim dozama. U praksi se rezistencija uočava kao postupni gubitak učinkovitosti fumiganta, a nastaje nakon što je populacija štetnika na terenu bila tijekom dužeg vremenskog razdoblja tretirana istim fumigantom ili fumigantom istog načina ...

Do Phosphine Resistance Genes Influence Movement and Dispersal Under Starvation?
Journal of Economic Entomology, 2013Phosphine 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 ...

Abstract Adults of a phosphine‐resistant strain of Sitophilus oryzae (L) were exposed to constant phosphine concentrations of 0.0035–0.9 mg litre −1 for periods of between 20 and 168 h at 25 °C, and the effects of time and ...

Phosphine gas has been used world-wide for more than four decades as an ideal fumigant for disinfestation of stored grains and other commodities. Its use as a safe fumigant of stored products has become even more important with recent restrictions on the production of the only alternative, methyl bromide.
