Meligethes aeneus (Coleoptera: Nitidulidae) resistance to lambda-cyhalothrin in the Czech Republic in 2012 and 2013
Susceptibility of Meligethes aeneus populations from the Czech Republic and Slovakia was tested with lambda-cyhalothrin (93 populations in 2012, 82 populations in 2013) using IRAC method No. 011 Version 3. Resistant populations predominated in both years. The mean percentage mortalities for a common...

| Summary: | Susceptibility of Meligethes aeneus populations from the Czech Republic and Slovakia was tested with lambda-cyhalothrin (93 populations in 2012, 82 populations in 2013) using IRAC method No. 011 Version 3. Resistant populations predominated in both years. The mean percentage mortalities for a common European field rate of 7.5 g a.i./ha were 60.95% in 2012 and 61.36% in 2013 (according to Abbott's formula). The LC50 values estimated for the tested populations exceeded the European field rate in many cases (22.09% of populations in 2012 and 17.14% in 2013). Only in 10.47% and 7.14% of populations the LC90 values were below the European field rate (in 2012 and 2013, respectively). Slovak populations seemed to be somewhat less resistant compared to the Czech ones. |
