| Abstract:
Biological efficacy of the most frequently used and some newly-introduced insecticides for controlling Colorado potato beetle (Leptinotarsa decemlineata Say) in Serbia was evaluated in Indjija (in 2000 and 2003), Zemun Polje (in 2002 and 2003) and Surcin (in 2002) localities, against 1st generation of CPB. Neonicotinoids (acetamiprid, imidacloprid and thiacloprid) and fipronil showed high average efficacy of 96.1-100% in all three localities. Chlorpyriphos+cypermethrin achieved significantly lower average efficacy of 42.3-80.8%, compared to the efficacy of thiacloprid and fipronil, in 2002. The average efficacy of B. thuringiensis-product (60.6-85.1%) was significantly lower than the efficacy of thiacloprid and fipronil, in Surcin in 2002, and acetamiprid efficacy in 2003. The importance of these results for L. decemlineata control is discussed. | |
