Abstract:

The bioassay was carried out in the laboratory at Regional Agricultural Research Station, Lam, Guntur at normal room temperature and humidity conditions during 2016-17. The commonly used neonicotinoid insecticides viz., imidacloprid 17.8 SL, acetamiprid 20 SP, thiamethoxam 25 WG and two organophosphate insecticides viz., acephate 75 SP and monocrotophos 36 SL were selected as test insecticides. The per cent mortality at 48 hrs after treatment was low with neonicotinoids when compared to organophosphates. The resistance ratio for imidacloprid, acetamiprid and thiamethoxam was 8.4, 12.9 and 9.4 folds, respectively. But, for organophosphate insecticides such as acephate and monocrotophos, it was only 2.3 fold and 2.9 fold, respectively. The results indicated that the leafhopper population of Guntur developed slight resistance to neonicotinoids such as imidacloprid 17.8 SL, acetamiprid 20 SP and thiamethoxam 25 WG when compared to organophosphate insecticides viz., acephate 75 SP and monocrotophos 36 SL.
