“…In China, Sitophilus zeamais (Motsch. ), commonly known as the maize weevil, and Tribolium castaneum (Herbst), commonly called the red flour beetle, have destructive effects on stored grain products [1], and infestations are typically controlled by fumigation techniques [2]. However, excessive use of synthetic fumigants and insecticides has several detrimental effects, including but are not limited to insecticide resistance, environmental contamination, and damage to human health and other non-target organisms [2,3].…”

“…), commonly known as the maize weevil, and Tribolium castaneum (Herbst), commonly called the red flour beetle, have destructive effects on stored grain products [1], and infestations are typically controlled by fumigation techniques [2]. However, excessive use of synthetic fumigants and insecticides has several detrimental effects, including but are not limited to insecticide resistance, environmental contamination, and damage to human health and other non-target organisms [2,3]. Research into alternative treatments has shown that essential oils and their constituents possess insecticidal properties against many stored-product insect pests [4][5][6]; therefore, these may be alternatives to currently used fumigants and insecticides.…”

“…Over the last decades, the fumigant insecticides phosphine and methyl bromide have been utilized for the control of insect pests in stored grains (Zettler & Arthur, 2000). However, the use of phosphine has been restricted due to the possibility of development of resistance in pest populations (Pimentel et al, 2007), and the utilization of methyl bromide has been limited because it is considered to be a depleting agent of the ozone layer (Bell, 2000).…”

The purpose of this work was to evaluate the transport of allyl isothiocyanate (AITC) by means of the sorption mechanism and the diffusion of AITC through maize grains. The experimental procedure to study the sorption mechanism was conducted by injection of AITC in glass flasks containing the grains. Kinetic models of zero, first and second order were fitted to AITC concentration data, with the purpose of determining the sorption rate (k). For the study of diffusion, a prototype was utilized in which the components are a gas chamber and a cylindrical column in which the grains were stored. At the interval of 110 min, samples in the chamber and in the column were collected, which were immediately injected into the gas chromatograph. In order to determine the effective diffusion coefficient (D ef ) of AITC through maize grains, the term referring to the sorption rate was added to the diffusion equation. The kinetic model of the first order was the one that best fitted the experimental data for the sorption mechanism, and k was 6.26 x 10 -4 s -1 . The D ef of AITC through grains was 7.2 x 10 -3 cm 2 s -1 . It was concluded that the transport of AITC through maize grains is slow, due to the low value of D ef and high sorption rate of this component by the grains.

“…In recent years, the importance of phosphine to protect stored grain products has grown due to international agreements phasing out the fumigant methyl bromide (Bell, 2000;Zettler & Arthur, 2000;Rajendran, 2001). 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).…”

“…The understanding of phosphine resistance mechanism in these insects is essential for their management, and may also greatly reduce the efforts and expenses for identifying synergists or novel replacement compounds (Bell, 2000;Zettler & Arthur, 2000;Rajendran, 2001;Chaudhry et al, 2004). The most accepted mechanism is the reduced uptake of the fumigant (Price, 1984), which may be closely linked to insect's respiration rate, and is generally overlooked.…”

-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.
