Web4. Phosphine Fumigation Parameters for Resistant Cigarette Beetles Two mechanisms of phosphine resistance have been determined in stored product insects: a mechanism of reduced phosphine uptake by active exclusion and an enhanced detoxification of phosphine (Price, 1984; Chaudhry and Price, 1990). Phosphine resistance is controlled by WebThe resistance ratio at LC(50) in T. castaneum ranged from 1.0- to 186.2-fold, in R. dominica from 2.0- to 71.0-fold and in O. surinamensis from 1.9- to 32.2-fold.

WebDec 23, 2010 · Phosphine resistance is not discussed in detail, but may be referred to as required to explain a mechanism of phosphine toxicity. Phosphine is widely used as a fumigant [ 2] as it is gaseous above −88°C with a density of 1.17 times that of air, which allows it to disperse readily during fumigation. WebDec 1, 2024 · Resistance to phosphine was detected in four out of 14 populations in adults and nine out of 14 populations in eggs and ranged from 2 to 100%.
