Description Not Available
Abundance of brown plant hopper (BPH) Nilaparvatalugens (Stål) (Delphacidae: Homoptera) is
modulated by prevalent weather conditions of rice growing seasons and locations. Categorization of
BPH adults caught in light traps (nos/week/trap) into low, moderate and high and formulation of criteria
accounting weather variables [maximum/ minimum/ mean temperature (ÚC), morning/evening/mean
relative humidity (%), rainfall (mm) and sunshine hours (h/day) and wind speed (km/h)] during kharif of
2011-16 for four locations viz., Ludhiana (Punjab), Chinsurah (West Bengal), Raipur (Chhattisgarh) and
Aduthurai (Tamil Nadu) with associated rules for weather based BPH prediction. Validation of BPH
predictions for kharif 2017 indicated 96, 87, 73 and 61% accuracies in respect of Aduthurai (TN), Raipur
(CG), Ludhiana (PB) and Chinsurah (WB). Future weather based predictions of BPH based on climatic
projections of representative concentration pathway (RCP) 4.5 for 2020, 2050 and 2080 indicated absence
of high population at Chinsurah (WB) during all time periods of 2020-2080. Progressively reducing BPH
abundance from past (2011) to all future periods was noticed at Aduthurai (TN). ‘High’ BPH from 2020
and beyond over 2011 and 2016 at Raipur (CG) and reducing ‘high’ but increasing ‘moderate’ category
between 2020-2050 but the reverse in 2080 at Ludhiana (PB) were predicted indicating requirement of
continued monitoring strategies put in place at these locations. The observed spatial variability of climate
change influence on BPH implied a need for zonation mapping of rice insects including BPH for India.
