Description The "Studies on insecticide resistance monitoring for brown planthopper Nilaparvata lugens (stal.) of Kampasagar area in Nalgonda district.” was conducted in the co supervision of department of Entomology, Indian Institute of Rice Research, Rajendranagar, Hyderabad during 2015-2016. Brown planthopper is considered to be most devastating pest of rice in India. The most commonly used method for controlling BPH is the application of insecticides which causes several problems such as development of insecticide resistance, environmental pollution and undesirable effects on non-target organisms. Development of pesticide resistance in any pest is an unavoidable consequence. Several new products are being developed and evaluated to find out suitable combinations for mitigating resistance effectively.
Bioefficacy of different insecticides against BPH population was tested under glasshouse conditions, revealed that the highest mortality (100.00%) of BPH was observed in Acephate 75 WP(100.00%), Dichlorvos 76 EC(100.00%), Dinotefuron 20 SG(100.00%) and Monocrotophos 36 SL. It was followed by Chlorpyriphos 20 EC(98.75%), Ethiprole 40 % + Imidacloprid 40% 80 WG (Glamore)(96.25%), Thiamethoxom 25 WG(96.25%), Pymetrozine 25 WG(95.00%) and minimum 42.5% mortality in Buprofezin 25 SC.
Monitoring of insecticide resistance in BPH population collected from Nalgonda district, Telangana, India was carried out during 2015-16, indicated that BPH populations from Nalgonda acquired very high level of resistance to buprofezin 25 SC (1408.59 fold). Nalgonda BPH population also acquired resistance to neonicotinoids like imidacloprid 17.8 SL (188.6-660.9 fold) and thiamethoxam 25 SG (50.1-138.1 fold) similarly to ethiprole 40%+ imidacloprid40% (glamore 80 WG) (222.2-430.5 fold). The population has developed low level of resistance to dinotefuron 20 SG (1.4-3.6 fold) and OP compounds like monocrotophos 36 SL (0.94-1.26 fold), dichlorvos 76 EC (0.28-0.77 fold), chlorpyriphos 20 EC (1.28-1.34 fold) and acephate 75 WP (0.28-2.02 fold). similarly negligible resistance to phenyl pyrazole compound i.e. fipronil 5 SC (1.36-1.96 fold) and one pyridine azomethines compound pymetrozyne 25 WG (1.1-1.5 fold).
On the basis of survey conducted at the BPH prone area of different villages of Nalgonda districts during kharif crop season, revealed that the farmers low level of awareness for BPH management practice among majority of respondents may be responsible for the emergence of BPH in that area
