Characterising metabolic resistance in pyrethroid‐insensitive pollen beetle (Meligethes aeneus F.) from Poland and Switzerland

Abstract

Differential synergism has enabled the characterisation of pyrethroid resistance in populations of M. aeneus. It was found to be principally due to an oxidative-based mechanism, and, if a synergist were to be used to inhibit this enzyme group, renewed control against resistant pests could be achieved.

Negative correlations between the susceptibilities of Czech and Slovak pollen beetle populations to lambda-cyhalothrin and chlorpyrifos-ethyl in 2014 and 2015

“…Some other studies also demonstrate that lower susceptibility (or resistance) of pollen beetles to esteric pyrethroids does not increase the risk of lower susceptibility of the pest to chlorpyrifos-ethyl at the same time (Philippou et al 2011;Slater et al 2011;Zimmer & Nauen 2011, also on http://www.iraconline.org). Wegorek and Zamoyska (2008) even described and documented a strong negative cross resistance between pyrethroids and chlorpyrifosethyl in pollen beetle populations in Poland (also in Wegorek et al 2009).…”

“…Wegorek and Zamoyska (2008) even described and documented a strong negative cross resistance between pyrethroids and chlorpyrifosethyl in pollen beetle populations in Poland (also in Wegorek et al 2009). The higher susceptibility to chlorpyrifos-ethyl in the pyrethroid resistant populations probably relates to the prevailing mechanism of resistance detected in populations from Central Europe (Philippou et al 2011). That is metabolic resistance which is based mainly on enhanced oxi- Oxidative enzymes (cytochrome P 450 monooxygenases) play the most important role in detoxification of pyrethroids in insect bodies (Moores et al 2009;Philippou et al 2011).…”

Meligethes aeneus (Coleoptera: Nitidulidae) resistance to lambda-cyhalothrin in the Czech Republic in 2012 and 2013

“…Based on this evidence resistance monitoring activities were initiated in many other European countries (Zimmer & Nauen 2011a,b). Consequently, resistant pollen beetles were also discovered in 2000 in Switzerland (Derron et al 2004) and in Sweden (Djurberg & Gustafsson 2007), in 2003 in Finland (Tiilikainen & Hokkanen 2008), in 2004 in Poland (Wegorek 2005;Wegorek et al 2006Wegorek et al , 2009Philippou et al 2011), and in 2007 in Luxembourg (Eickermann et al 2008). The first cases of pyrethroid resistance in Denmark were described in 2000and 2001and confirmed in 2003(Hansen 2003.…”

Efficacy of different insecticides in controlling pollen beetle (Meligetes aeneus F.) in rapeseed crop

“…Years of repetitive application of insecticides, often not fully justified, have lead to reduced susceptibility or resistance of various populations of M. аeneus (Hansen, 2003), such as reported from different parts of Europe, e.g. France (Delorme et al, 2002), Germany Glattkowski et al, 2008;Müller et al, 2008), Denmark (Hansen, 2003(Hansen, , 2008, Switzerland (Derron et al, 2004;Philippou et al, 2010), Austria, Sweden (Kazachkova, 2007) and Poland (Węgorek, 2005;Węgorek et al, , 2007Węgorek et al, , 2009Wegorek andZamojska, 2006, 2008;Philippou et al, 2010). As pyrethroid insecticides are primarily used against this pest species in our country and globally, resistance to that group of insecticides has become most evident (Derron et al, 2004;Heimbach et al, , 2007Hansen, 2008).…”
