A field experiment was conducted during kharif 2011 and 2012 at research farm of Institute of Pesticide Formulation Technology, Gurgaon (Haryana) to evaluate the bioefficacy of new insecticide imidacloprid (0.3 G) @ four differential doses, viz 10, 15, 20 and 40 kg/ha along with standard check, phorate (10G) @ 25 kg/ha and imidacloprid (200SL) @ 500 ml/ha against Holotrichia consanguinea Blanch in groundnut crop. All doses of insecticides were used as soil application in groundnut (Arachis hypogaea L.). Imidacloprid (0.3 G) @ 15, 20 and 40 kg/ha recorded a significant reduction in percent plant mortality compare to standard checks (phorate (10G) @ 25 kg/ha and imidacloprid (200SL) @ 500 ml/ha) and untreated check during both cropping seasons. The lowest (8.23 and 10.27) percent plant mortality was recorded in imidacloprid (0.3G) @ 40 kg/ha during both the cropping seasons. It was however, at par with its lower doses @ 15 and 20 kg/ha. Imidacloprid (0.3 G) @ 10 kg/ha recorded the percent plant mortality up to 17.97 and 15.73 during 2011 and 2012, respectively. A significantly higher yield was recorded under all the treatments doses over untreated check during both the years. Among the treatments a highest yield (1 810 and 1 830 kg/ha) of dry pod was recorded in imidacloprid (0.3G) @ 40 kg/ha during both the cropping seasons. It was however at par with its lower doses, i.e. imidacloprid 0.3G @ 15 and 20 kg/ha. Imidacloprid (0.3G) @ 20 kg/ha exhibited maximum net return of R 64 078 ha. Hence, imidacloprid 0.3 G at 20 kg/ha may be recommended for the management of H. consanguinea on groundnut cultivated in sandy loam soil of Haryana. © 2015, Indian Council of Agricultural Research.

The study was carried out to isolate and identify the symbionts, viz. cellulose demoting bacteria and fungus in termite gut. The experiment was conducted during (February 2013-July 2013) at biotechnology laboratory, Institute of Pesticide Formulation Technology, Gurgaon (Haryana). Termites are wood eating insects and are among the most important ligno cellulose-digesting insects and possess a variety of symbiotic microorganisms in their gut. Nutrient agar, potato dextrose and Carboxy Methyl Cellulose (CMC) were used to isolate the dry bacterial strain and fungus. The cellulose is demoted in termite gut by the production of cellulase enzyme which is detected by Congo red stain. Colony morphology and staining technique such as Gram's staining, Congo red staining and oxidase test for bacterial strain gave an idea for the presence of genera Citrobacter and Enterobacter. Aspergillus nidulans has been isolated and identified at division of plant pathology, IARI, New Delhi. These bacteria and fungus were able to assimilate CMC which aid in digestion of cellulose in subterranean termite Odontotermes obesus (Rambur) and this study abetted to understand more about the symbionts associated with digestive mechanism of termites.
