Determination of abamectine resistance levels and g314dmutation of populations of tetranychus urticae koch (Acarina:Tetranychidae) collected from greenhouse floriculturegreenhouses in Antalya

Tetranychus urticae Koch (Acari: Tetranychidae) is a mite species that is the pest of many crops in our country and in the world. T. urticae causes significant economic losses in many industrial plants, ornamental plants, fields and greenhouse production areas. In this study, LC values, resistance rates and presence of G314D point mutation for abamectin of T. urticae populations were investigated collected from cut flower production greenhouses in Antalya. Leaf disc‐spray tower method was used in determination of LC values. The resistance levels were determined by the LC50 values of the field populations were compared to the LC50 values of the susceptible population. LC50 values of the GSS, SV1, SV2, AO1, AO2, AO3, AO4, AO5 and AO6 populations has determinated as 1,63; 381,55; 350,25; 1385,71; 1207,79; 2,62; 321,95; 414,29 and 377,73 μl/100 ml water, respectively. The resistance rates of field populations was found between 1.61 ‐ 850 fold according to LC50. Also, G314D point mutation which is common in resistant mites, was investigated with using specific probes to mutations by real‐time PCR. G314D point mutation was not determined in 8 field and susceptible GSS populations.
