| dc.description.abstract | Present investigation was carried out at the botanical garden, University of Agricultural Sciences, GKVK, Bangalore during 2013-14. The insecticides viz., clothianidin 7.5 CS, fipronil 5 SC and bifenthrin 8 EC were evaluated against termites by different methods viz., modified ground board method (MGBM), petri dish method, glass tube test method and wood treatment. The impact of these insecticides on non-target soil biota was also assessed. In MGBM, clothianidin @ 0.1, 0.075 and bifenthrin @ 0.05% protected the wood bait up to 11 months. LT50 values for Odontotermes horni workers was lowest in bifenthrin @ 0.05% (3.69 h) followed by clothianidin @ 0.1% (4.99 h), clothianidin @ 0.075% (5.61 h), fipronil @ 0.075% (6.37 h), clothianidin @ 0.05% (7.23 h) and clothianidin @ 0.025% (7.66 h) at 1 MAT in petridish (Bioassay) method. Lower penetration and higher mortality of termites was noticed in soil treated with clothianidin @ 0.075%, 0.1% and bifenthrin @ 0.05% in glass tube test method. The wood stakes treated with the insecticide solutions were effective in repelling the termites up to 11 MAT. The toxicity of chlorpyriphos on total soil invertebrates was more and was on par with imidacloprid. Soil application of chlorpyriphos was found to be significantly more toxic to collembolans. Imidacloprid treated soil showed significantly higher toxicity to cryptostigmata. On the other hand, propargite found more toxic to other acari. Other invertebrates were more susceptible to the chlorpyriphos and was on par with fipronil, imidacloprid and buprofezin. Relative abundance of soil invertebrates also documented. | en_US |
