“…The evolution of phosphine resistance among the insect pest population asserts the need of increasing the exposure time further to control resistant populations. For instance it was 7 days (Taylor and Harris 1994;Bengston et al 1997;Rajendran and Muralidharan 2001), later 8 days (Rajendran and Gunasekaran 2002;Collins et al 2005), 6-9 days (Price and Mills 1988;Liang et al 1999;Collins et al 2002) and more than 7 days (Sayaboc et al 1998) for phosphine-resistant Rhyzopertha dominica. The differences between the age-groups of the tolerant stages are extremely higher for phosphine fumigant (Howe 1973).…”

The susceptibility of the developmental stages of rust-red flour beetle, Tribolium castaneum to a range of concentrations of phosphine over varying durations from 24 to 168 h was reconnoitered in the laboratory at 25 ± 2°C. Responses of the life stages exposed to phosphine were compared with those of un-treated controls over 24, 48, 72, 96, 120, 144 and 168 h exposures and mortality was assessed after 14 days. Among the life stages tested, pupae were more tolerant to phosphine followed by the egg and the larval instars. At 24 h, the maximum LC 50 value was observed in case of egg; 1.571 mgL −1 ; followed by the pupae, 6 th instar, 4 th instar and 2 nd instar larvae with LC 50 values of 1.184, 0.336, 0.212 and 0.081 mgL −1 respectively. However, continued exposure of the developmental stages to phosphine, recorded maximum LC values in the pupae followed by egg and the larval instars. A linear increase in the mortality response was witnessed in all the insect stages when the exposure periods were extended from 24 to 168 h with increasing concentrations of phosphine, conversely significant increase in mortality was greatly apparent during the initial treatment periods.

“…AlN, Al, Al(OH) 3 , Mg 2+ and As (below 0.04%) were found to be present, in addition to AlP, in the technical and formulated AlP products. Al(OH) 3 is produced by the reaction of AlP with H 2 O.…”

“…The ESCA spectrum measures the kinetic energies of electrons ejected from a molecule by a mono-energetic beam of X-radiation. Aluminum phosphide and its formulated products are important insecticides still used in stored products and agricultural fields [2,3]. Up to now, the impurity elements and their forms among these products are unknown due to the analytical difficulties with either chromatography or common chemical analysis.…”

XPS-ESCA analysis showed small signal for phosphorus in fresh specimens of aluminum phosphide (AlP). After removal of a layer of about 0.5 -1.0 µm by argon ion sputtering, it was observed that signal intensities from oxygen and aluminum increased. The oxygen signal decreased as a function of sputtering time, synchronously with the increase of the phosphorous signal from the AlP nucleus. The aluminum signal, which was considered to be mainly due to AlP and Al(OH) 3 , remained constant. Other impurity elements including N, Mg, etc., were identified in the technical 85% AlP and AlP tablet formulated products.

“…However, the use of methyl bromide is prohibited in India (Anonymous 2012). Phosphine has been used in a variety of habitats for long time (Rajendran and Muralidharan 2001). Conventional use of phosphine has not been successful in controlling insects because certain insects have developed resistance to phosphine (Bell and Wilson 1995).…”

Contamination of stored grain with insects, insect fragments, fungi, and mycotoxins is a major concern of the grain industry. The stored-grain insects affect the grains not only quantitatively but also qualitatively. Disinfestation of grains can be achieved by physical, chemical and thermal methods. Microwaves may be an alternate to chemical methods of killing insects in grain as their application do not leave any undesirable residues and thus might be very effective for controlling insect infestation compared to other available methods. Microwave disinfestation can provide a continuous process to allow large quantities of products to pass in a shorter period of time. Microwave disinfestation is considered safe and competitive alternative method to fumigation as it avoids environmental pollution. The aim of this review is to examine how the use of microwave treatment benefits grain producers, handlers, and processors seeking to use non-chemical methods for preventing and controlling insect infestation and fungal growth during storage.
