Review:Resistance to Insecticides in Storedproduct Insects and Its Mechanisms

摘要

In this review, we briefly describe the major species of stored-product insects. We concentrate particularly on the economic importance of the control of these insect pests, highlighting a final cost of more than one billion of dollars world-wide. Then we describ in detail and focus our review on the different mechanisms of resistance described in these species. This work is centred on the main ways the resistances described most recently in these insects. First, we detail common description of species resistance throughout the world. We observed 27 recurrent species involved in resistance cases occurring on 5 continents. Resistance is commonly expressed as a factor. Field-collected strains expressed 1.3 to 1 194 fold resistance compared with sensitive strains according to the considered species and insecticide. Described resistance mechanisms include:behavioral resistance, particularly described with Oryzaephilus surinamensis, the involvement of detoxifying enzymes （particularly esterases, monooxygenases and transferases) and studies on the genetic resistance, involving the Kdr mutation mechanisms, the transmission of the genes of resistance. We detail all these mechanisms and give some advice on the need for further research some possible future studies, emphasising the need for more collaboration between laboratories from different countries. We dedicate a section to cross-resistance and the multiple resistance due to the many mistakes and different meaning we can find in several articles. Finally,we conclude with pathways that could be followed to increase our knowledge of the development of resistance. We think that studies on genetic diffusion in species and populations of stored-productpests are necessary. These studies are needed to understand the development and the diffusion of the resistance to insecticides.
