“…A similar result has been demonstrated in previous studies (Silcox et al 1985, Zehnder 1986, Zehnder and Gelernter 1989. Differential susceptibility to insecticide between L. decemlineata larvae and adults suggests that susceptibility studies performed for one life stage may not accurately reßect insecticide susceptibility in community level.…”

The susceptibility status of Colorado potato beetle, Leptinotarsa decemlineata (Say), adults to phosalone was determined by dip and glass jar assay techniques. Bioassay results indicated a narrow variation in Colorado potato beetle insecticide susceptibility among sample sites. LC50 values were generally highest from specimens collected in field that received frequent phosalone applications for seven consecutive growing seasons. In five populations tested, LC50 values ranged from 503.72 to 827.95 ppm in dip test method. In glass jar technique, resistance ratio value of 1.72 for LC50 was obtained. A significant linear relationship between LC50 values of individual populations across test methods was detected. Both bioassay techniques were suitable for monitoring resistance to insecticide in Colorado potato beetle adult populations. Glass jar technique, however, exhibited less variability in LC50 estimates and showed a higher degree of sensitivity than the dip method. Filter paper and leaf disk techniques for larvae were two bioassay methods used to determine phosalone susceptibility in L. decemlineata populations. Both bioassay techniques exhibited a similar level of susceptibility of the larvae to phosalone; however, the fiducial limit values from filter paper method were narrow than the leaf disk assay technique. A significant direct relationship between LC50 values of individual population across test methods was observed. Differences in LC50 ranking among fields between adults and larvae indicated a differential susceptibility to insecticide between life stages. Low LC50 values obtained from Colorado potato beetle in sample sites indicated that phosalone resistance was not severe in these fields. The glass jar and filter paper testing methods are simple and sensitive test techniques for measuring susceptibility of Colorado potato beetle adults and larvae to phosalone, respectively.

“…Because differences in susceptibility to insecticides may be considerable among Colorado potato beetle life stages, LD50 or LC50 values and resistance ratios may differ depending on which life stage was assessed (Silcox et al 1985;Zehnder 1986;Zehnder and Gelernter 1989;Wierenga et al 1996;Zhao et al 2000). For example, imidacloprid resistance ratios differed by almost an order of magnitude when measured in second instar larvae compared to adults (Zhao et al 2000).…”

“…Resistance levels vary greatly among different populations (Forgash 1985;Boiteau et al 1987;Mowry and Sandvol 1995;Stewart et al 1997;Olson et al 2000) and between beetle life stages (Silcox et al 1985;Zehnder 1986;Zehnder and Gelernter 1989;Pourmirza 2005), but in some cases could be very high. For example, Harris and Svec (1981) detected more than 1,600-fold increase in the LD50 of carbofuran in the field population from Quebec.…”

“…In vivo, pre-treatment by an oxygenase inhibitor piperonyl butoxide (PBO) reduced resistance of adult beetles resistant to azinphosmethyl (Ahammad-Sahib et al 1994), carbofuran and carbaryl (Rose and Brindley 1985), fenvalerate (Soderlund et al 1983;Silcox et al 1985;Harris and Turnbull 1986), permethrin (Silcox et al 1985), and in fourth instar larvae reduced the resistance to abamectin (Yoon et al 2002). Similarly, imidacloprid-resistant beetles from Long Island, New York showed a reduction in resistance from 300-fold without PBO treatment to 108-fold with PBO treatment (Mota-Sanchez et al 2006).…”

“…The substance known to block the activity of mixed function oxidases is piperonyl butoxide (PBO). This compound, which creates a stable complex with cytochrome P-450, blocks enzymes responsible for insecticide detoxification in insects (Silcox et al 1985;Tozzi 1998). PBO is also known to block nonspecific esterases in some insect species (Gunning et al 1998;Moores et al 2009;Young et al 2005).…”

High resistance to pyrethroid insecticides in the Polish pollen beetle (Meligethes aeneus F.): the role of oxidative metabolism

2011

Pollen beetle (Meligethes aeneus F.) (PB) causes very serious problems in oilseed rape (Brassica napus var. oleifera L.) cultivations in Poland and other European countries. Pyrethroid insecticides are the most frequently used type for controlling PB in Poland. This chemical group has been used in Poland since the beginning of the 1980's and its strong selection pressure on PB resulted in some level of resistance of this pest to many active substances. The aim of this investigation was to analyze, with the use of synergists, the main mechanisms responsible for resistance of PB to pyrethroids. The results indicate the main resistance factor in Polish PB populations to be monooxygenase enzymes.
