“…Résistance was most prévalent in populations from Manitoba, which is consistent with the results of a previous survey, where populations from 21 of 55 potato fields in Manitoba were found to be résistant toat least one of the nine insecticides tested (Gavloski 1997). Although the diagnostic concentrations used in this study were calculated for résistant and susceptible populations from North Carolina, they were verified by Stewart et al (1997) for populations from Prince Edward Island and Ontario, and for a résistant and susceptible population from Ontario in this study. However, we hâve chosen to report our results according to level of susceptibility to French et al's (1992) diagnostic concentrations ratherthan to probability of field control (Kennedy and French 1994), because base-line data on the susceptibility of beetle populations from western Canada had not yet been determined and consequently, local résis-tant and susceptible populations were not available for us to verify thèse diagnostic concentrations.…”

La sensibilité du doryphore de la pomme de terre (Leptinotarsa decemlineata) de trois provinces de l’Ouest canadien a été mesurée par bioessai sur papier filtre pour corroborer les comptes rendus faisant état de doryphores résistants aux insecticides au Manitoba, et pour comparer la situation au Manitoba à celles de la Saskatchewan et de l’Alberta. La sensibilité des doryphores a été mesurée pour cinq insecticides : les organophosphates azinphos-méthyl (Guthion) et méthamidophos (Monitor), le pyréthroïde perméthrine (Ambush), l’organochloré endosulfan (Endosulfan) et le carbamate carbaryl (Sevin). Les 12 populations du Manitoba examinées démontraient de la résistance à au moins un des insecticides. Toutes les populations ont été classées comme étant résistantes ou moyennement résistantes à la perméthrine; deux des populations ont été classées comme résistantes à l’azinphos-méthyl et trois au méthamidophos. Deux des quatre populations de la Saskatchewan ont été classées comme étant moyennement résistantes à l’azinphos-méthyl et au méthamidophos. Une résistance intermédiaire à la perméthrine a été trouvée dans 12 des 13 populations de l’Alberta, alors qu’une seule était très sensible. Deux populations se sont montrées moyennement résistantes à l’azinphos-méthyl et trois au méthamidophos. Dans les trois provinces, le taux de survie de diverses masses d’oeufs provenant de populations sensibles variait de 0 à 100 %, ce qui montre que des individus résistants, moyennement résistants et très sensibles coexistent dans ces populations. Avec l’expansion de la culture de la pomme de terre dans l’Ouest canadien et la détection d’une résistance aux insecticides dans les populations du doryphore de la pomme de terre, un programme de gestion de la résistance doit être mis en place pour éviter la sélection rapide de populations résistantes.The susceptibility of Colorado potato beetles (Leptinotarsa decemlineata) (CPB) from three provinces in western Canada was measured using a filter paper bioassay to substantiate the reported insecticide resistance by the beetle in Manitoba, and to compare the situation there to beetle populations from Saskatchewan and Alberta. Susceptibility of beetles was measured against five insecticides: the organophosphates, azinphos-methyl (Guthion), and methamidophos (Monitor); the pyrethroid, permethrin (Ambush); the organochlorine, endosulfan (Endosulfan); and the carbamate, carbaryl (Sevin). All 12 populations tested from Manitoba were found to have resistance to one or more of the insecticides. All populations were classified as either having resistance or intermediate resistance to permethrin; two of the populations were classified as having resistance to azinphos-methyl and three to methamidophos. Two of four populations from Saskatchewan were classified as having intermediate resistance to azinphos-methyl and methamidophos. Intermediate resistance to permethrin was recorded in 12 of the 13 populations from Alberta, with only one being highly susceptible. Two populations showed evidence of interme...

“…In Canada, insecticide résistant populations hâve been reported from most of the eastern provinces where potatoes are grown (Boiteau 1988;Boiteau et al 1987;Harris and Svec 1976;Stewart et al 1997). The first reports of résistance were to organochlorine insecticides (Harris and Svec 1976;McClanahan 1975;McDonald 1976).…”

“…In subsequent years, failures have been reported for most major classes of insecticides (Table 2). Although the northeastern United States is one of the main problem areas (Forgash 1985;Whalon and Ferro 1998), insecticide resistance in the Colorado potato beetle is a truly global phenomenon (Hofmaster et al 1967;Forgash 1985;Boiteau 1988b;Ioannidis et al 1991;Heim et al 1992;Stewart et al 1997;Noronha et al 2001;Stankovic et al 2004;Pourmirza 2005;Mota-Sanchez et al 2006;Benkovskaya et al 2006;Mohammadi Sharif et al 2007;Whalon et al 2008). Obviously, not every beetle population is resistant to every single compound that has ever been observed to fail against this pest.…”

“…Olson et al (1996) determined susceptibility to azinphosmetil for 9 of 35 populations, while the others were significantly or moderately resistant. Stewart et al (1997) determined significant resistance to carbosulfan and azinphosmetil. Argentine et al (1994) and Miyo et al (1999) determined that resistance to azinphosmetil is inherited by an autosomal gene, incompletely dominant.…”

Leptinotarsa decemlineata (Say), the Colorado potato beetle (potato beetle), is the most destructive potato pest in Serbia. Up to four pesticide treatments are necessary for its control. Insecticide resistance of the potato beetle in Serbia is well-investigated and documented, especially to organophosphates and carbamates. Toxicity of chlorpyriphos (organophosphates) and carbosulfan (carbamates) was investigated by topical application, using adults of the first generation from nine field populations. Adults of all populations possessed a certain level of resistance to both insecticides, with very low regression slopes (0.50-1.09 for chlorpyriphos and 0.57-0.85 for carbosulfan). Resistance ratios for chlorpyriphos ranged from 1.0 to 109.7 and from 1.0 to 52.8 for carbosulfan. There was no correlation between resistance to chlorpyriphos and carbosulfan. The key modes of resistance to organophosphates and carbamates are metabolism [overproduction of aliesterase (ALiE), a carboxylesterase] and altering the target site of acetylcholine esterase (AChE). Biochemical research of potato beetle resistance to organophosphates and carbamates, based on activity of ALiE and AChE, proved that the key mode of resistance to organophosphates was modification of ALiE and AChE to carbamates. Our results correspond to this research concerning the lack of correlation between resistances to these two insecticides. A certain level of resistance of the potato beetle to organophosphates and carbamates is widespread in Serbia. Different modes of resistance suggest the possibilities of control of this pest, such as choice of insecticide and insecticide rotation, wherever possible.
