Evaluation of Spinetoram against Odontotermes Brunneus Hagen (Isoptera: Termitidae) in laboratory and field condition

Author(s): Vijay Laxmi Rai, AK Karnatak and Shivashankara
Abstract: Field experiments were carried out during 2013-14 in N. E. B. Crop Research Centre of G.B.P.U.A.&T., Pantnagar (Uttarakhand) to evaluate the field efficacy of spinetoram 11.7% SC against termites in sugarcane crop. Sugarcane cultivar CoP 97222 was used for experiment. The plot size was 8 ×5 m2, row to row distance 90 cm, 3 budded setts were used as planting material and date of planting was 20 March, 2013. The experiment was laid out in a randomized block design with four replications. Six treatments including control were allocated randomly to different plots in each of the three blocks. Foraging workers were collected from termitarium present near Practical crop production, campus of GBPUA&T, Pantnagar. The termite individuals were transferred separately in three glass jars (dia. 20 cm, height 15 cm) having an inner lining of moist filter paper. These jars with termite individuals were kept in laboratory at room temperature (250C and 80 ± 5% RH) in dark conditions. The top of the jar was covered with slightly moist muslin cloth. All termites were tested within three days of collection and only active and healthy termites were used for the experiments. Spinetoram belongs to spinosyn group, which have novel mode of action and are widely used for the management of various agricultural pest. In this study, Spinetoram 11.7 w/w evaluated for their efficacy in laboratory as well as in sugarcane crop field. In the laboratory test, it was found that at 24HAE, efficacy of Spinetoram (LC50 31.9 ppm) was higher as compare to Imidacloprid (LC50 52.5 ppm) while field evaluation of insecticides application against termites in sugarcane crop showed the order of efficacy of various treatments as Spinetoram (1500 > 750 ml/ha) > Chloropyrifos> Fipronil > Imidacloprid > Control.
