“…The application of fumigant mixtures has been recognized as a means of overcoming the disadvantages of using a single fumigant. A combination of fumigants is advisable, because none of the common fumigants, used singly, possesses the ideal characteristics (Navarro et al , 1986; Athie et al , 1998).…”

This review describes the major stored-product insect species and their resistance to insecticides. The economic importance of the control of those pests is highlighted with a loss of more than one billion US dollars per year worldwide. A detailed common description of species resistance throughout the world has been developed, and we observed 28 recurrent studied species involved in resistance cases disseminated on the five continents. The different mechanisms, including behavioral resistance, were studied particularly on Oryzaephilus surinamensis. The role of detoxifying enzymes and studies on the genetic resistance, involving the kdr mutation mechanisms and the transmission of the genes of resistance, are also described. A chapter clarifying definitions on cross and multiple resistance is enclosed.

Genetics of phosphine resistance in the rice weevil Sitophilus oryzae (L.) (Coleoptera: Curculionidae)

The rice weevil, Sitophilus oryzae (Linnaeus) is a cosmopolitan insect pest that can cause severe damage to stored grain with regard to both quality (loss of nutritional and aesthetic value) and quantity (loss of grain weight). Heavy reliance on the fumigant phosphine to disinfest stored products has led to resistance to phosphine in many insect species including S. oryzae. The frequency and level of phosphine resistance in S. oryzae has increased in the last fifty years in Asian and Africa countries and recently in Australia as well. A strongly phosphine resistant strain of S. oryzae was first detected in 2009 in Australia. I have determined the strong resistance trait in this strain to be incompletely recessive, autosomal and controlled by at least two major genes. The weakly resistant Australian strain shares a common resistance factor with the strongly resistant strain (So_rph1), which is responsible for weak resistance. I also compared the resistance trait of the Australian strain to that of collected from Vietnam and China. Complementation analysis revealed a shared genetic mechanism of phosphine resistance between the three strains that I tested.I then identified and sequenced the genes conferring phosphine resistance in this species.This process began with simply sequencing transcripts of the two genes known to be responsible for phosphine resistance in Rhyzopertha dominica and Tribolium castaneum (rph1/tc_rph1 and rph2/tc_rph2). rph2/tc_rph2 had been published and was known to encode the metabolic enzyme, dihydrolipoamide dehydrogenase (DLD). Variants of DLD (So_rph2) also cause strong resistance in S. oryzae when interacting with resistance variants of So_rph1. Therefore, rph2/DLD is responsible for strong resistance in each of the three species. A specific substitution mutation (N505T) in DLD is likely responsible for phosphine resistance as it is found in all strongly resistant strains of S. oryzae from Australia, Vietnam and China. A fitness cost associated with the resistance allele of So_rph2 was observed in the absence of selection in populations derive from the F 1 progeny between a strongly resistant strain and strains lacking a resistance allele at So_rph2.As DLD is one of three subunits (E1, E2, E3) of α-ketoacid dehydrogenase complexes, Ihypothesized that suppression of the activity of subunits other than DLD might also result in resistance to phosphine. Thiamine pyrophosphate is critical cofactor of the E1 subunit and is required by very few other enzymes. I reasoned that insects cultured on a diet of white rice, which is deficient in thiamine, would experience inhibition of the activity of E1. I expected to observe the change in response to phosphine in both the susceptible and ii resistance strains of S. oryzae when fed on white rice diet compared with the thiamine containing diet of whole grain (brown rice or whole wheat). Against my expectation, I found no significant affect of a thiamine deficient diet toward phosphine resistance in S. oryzae.A diet of white rice, however, did ...

“…Malathion resistance in stored-product insect-pests has been reported from all over the world (Rassmann, 1988;Sayaboc and Acda, 1990;Zettler and Cuperus, 1990). Navarro et al (1986) reported malathion resistance of T. castaneum, O. surinamensis, S. oryzae and R. dominica. Malathion resistance in T. castaneum was reported from India by Pasalu and Bhatia (1983).…”

Conventional pesticides are being used as the major tools for stored grain and food protection. Many conventional pesticides have created problems including pesticide resistance, toxic residues in the treated products, handling hazards, health hazards to operatives and pest resurgence. Among these, the incidence of pesticide resistance is a growing problem in stored product protection. Problems associated with synthetic pesticides, especially pesticide resistance, have created a worldwide interest in the development of alternative biorational strategies. Plant-derived materials, biological control agents, insect growth regulators, solar disinfestation systems, use of inert dusts and diatomaceous earth, etc., are potential viable alternatives. Most of these alternatives have low toxicity or are not toxic to humans, making them environmentally acceptable and enabling them to be incorporated in stored product protection.
