Studies on the inheritance of phosphine resistance in T. castaneum show that there are two broad levels of resistance (weak and strong) in this species, with two major genes (rph1 and rph2) controlling their expression (Bengston et al, 1999;Jagadeesan et al, 2012). Insects with weak resistance are homozygous for rph1 and insects with strong resistance are homozygous for both rph1 and rph2.…”

a b s t r a c tThe prevalence of resistance to phosphine in the rust-red flour beetle, Tribolium castaneum, from eastern Australia was investigated, as well as the potential fitness cost of this type of resistance. Discriminating dose tests on 115 population samples collected from farms from 2006 to 2010 showed that populations containing insects with the weakly resistant phenotype are common in eastern Australia (65.2% of samples), although the frequency of resistant phenotypes within samples was typically low (median of 2.3%). The population cage approach was used to investigate the possibility that carrying the alleles for weak resistance incurs a fitness cost. Hybridized populations were initiated using a resistant strain and either of two different susceptible strains. There was no evidence of a fitness cost based on the frequency of susceptible phenotypes in hybridized populations that were reared for seven generations without exposure to phosphine. This suggests that resistant alleles will tend to persist in field populations that have undergone selection even if selection pressure is removed. The prevalence of resistance is a warning that this species has been subject to considerable selection pressure and that effective resistance management practices are needed to address this problem. The resistance prevalence data also provide a basis against which to measure management success.Crown

“…These genes are incompletely recessive and not sex-linked. Weakly resistant strains have been reported to be up to 12.7 times more resistant than susceptible strains, and a strongly resistant strain over 431 times more resistant, based on adult mortality after a 20-h exposure to phosphine (Bengston et al, 1999;Jagadeesan et al, 2012).…”

“…(Benhalima et al, 2004;Wang et al, 2006). Also, due to poor fumigation standards (Lorini et al, 2007), phosphine concentration does not reach the level required for selection of resistance at immature stages (Bengston et al, 1999;Collins et al, 2002Collins et al, , 2005Benhalima et al, 2004). The phosphine resistance detected among the populations may be the result of previous selection pressure caused by inadequate fumigations in the storage units, from where the samples were taken.…”

“…These advantages have contributed to increased dependence on this fumigant (Chaudhry, 2000;Hasan & Reichmuth, 2004;Wang et al, 2006). However, long-term use of a single fumigant also increases the risk of appearance of resistant pest populations (Bengston et al, 1999;Collins et al, 2002;Daglish, 2004).…”

“…In addition, the lack of ideal airtight conditions for fumigation, in most storage units, increases the frequency of control failures and, consequently, increases the frequency of applications Chaudhry, 2000;Benhalima et al, 2004;Lorini et al, 2007). These factors combine to result in higher selection pressure for phosphine resistance (Bengston et al, 1999;Collins et al, 2002).…”

-The objectives of this work were to assess phosphine resistance in insect populations (Tribolium castaneum, Rhyzopertha dominica, Sitophilus zeamais and Oryzaephilus surinamensis) from different regions of Brazil and to verify if the prevailing mechanism of phosphine resistance in these populations involves reduced respiration rates. Sixteen populations of T. castaneum, 15 of R. dominica, 27 of S. zeamais and eight of O. surinamensis were collected from 36 locations over seven Brazilian states. Each population was tested for resistance to phosphine, based on the response of adults to discriminating concentrations, according to FAO standard method. For each insect species, the production of carbon dioxide of the most resistant and of the most susceptible populations was inversely related to their phosphine resistance. The screening tests identified possible phosphine resistant populations. R. dominica and O. surinamensis were less susceptible to phosphine than the other two species. The populations with lower respiration rate showed a lower mortality at discriminating concentration, possibly related to a phosphine resistance mechanism. Phosphine resistance occurs in stored-product insects, in different regions of Brazil, and the resistance mechanism involves reduced respiration rate.Index terms: Oryzaephilus surinamensis, Rhyzopertha dominica, Sitophilus zeamais, Tribolium castaneum, fumigant resistance, respiration rate. Resistência de insetos de produtos armazenados à fosfinaResumo -Os objetivos deste trabalho foram avaliar a resistência à fosfina, em populações de insetos (Tribolium castaneum, Rhyzopertha dominica, Sitophilus zeamais e Oryzaephilus surinamensis), de diferentes regiões do Brasil, e verificar se o mecanismo predominante de resistência à fosfina, nessas populações, envolve a redução das taxas respiratórias. Dezesseis populações de T. castaneum, 15 de R. dominica, 27 de S. zeamais e oito de O. surinamensis foram coletadas em 36 locais de sete estados brasileiros. Cada população foi testada quanto à resistência à fosfina, com base na resposta dos adultos à concentração discriminante, de acordo com o método padrão da FAO. Para cada espécie de insetos, as produções de dióxido de carbono da população mais resistente e a da mais suscetível foram inversamente relacionadas à resistência à fosfina. Os testes de detecção identificaram possíveis populações resistentes à fosfina. R. dominica e O. surinamensis foram menos suscetíveis à fosfina do que as outras duas espécies. As populações com menor taxa respiratória apresentaram menor mortalidade à concentração discriminante, o que está possivelmente relacionado ao mecanismo de resistência à fosfina. A resistência à fosfina ocorre em insetos de produtos armazenados, em diferentes regiões do Brasil, e o mecanismo de resistência envolve a redução da taxa respiratória.Termos para indexação: Oryzaephilus surinamensis, Rhyzopertha dominica, Sitophilus zeamais, Tribolium castaneum, resistência a fumigante, taxa respiratória.
