“…The graphical constructions of mean, maximum and minimum abundance of BPH for each of SMWs across seasons in respect of each study location for the period of kharif (22-44 SMWs) served as the basis for categorizations (Vennila et al, 2016). Secondly, congenial conditions of weather for BPH development reported in literature (Krishnaiah, 2014;Rath et al, 2020) and their multiplication rate at 31+ 2! and the variability of the observed weather factors of 22-44 SMWs of 2011-16 were accounted to formulate suitable weather based criteria for each location.…”

“…Weather variables of temperature and relative humidity with their range of values constituting criteria in respect of locations are given in Table 2 along with a common rule of prediction. The inter seasonal variability of each of weather variables viz., temperature (Tmax, Tmin and Tmean in R°C), relative humidity (morning (RHI),evening (Krishnaiah, 2014). Nevertheless, the conducive weather in combination with factors of crop production including the intensity of rice cultivation and resurgence of the insect to applied insecticides determine BPH abundance.…”

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 of2011-16 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.

Brown planthopper's third and fourth instar nymphs have been reported to be more devastating among the different life stages [2]. Brown slope is also a vector of the spread of grass dwarf and empty dwarf disease whose damage can be greater than the attack of brown planthopper itself [7], [8].…”

Brown planthopper (Nilaparvata lugens Stal.) is one of rice plants' pests that attack from the nursery to the harvest stage. Controls carried out by farmers generally use synthetic insecticides. Reducing the impact caused by synthetic insecticides, an alternative that can be used to controlling the brown planthopper is by using botanical insecticide tuba root. Tuba root plants have been widely reported to control pests and contain the active ingredient rotenone. Rotenone works as a stomach poison and selective. This study aims to examine the ability of tuba root plant parts extracts (leaves, branches, and roots) with organic solvents to control brown planthopper pests in rice plants. The study was conducted in February-April 2019 at the Plant Pest Laboratory, Faculty of Agriculture, University of Riau. The study was conducted experimentally using a Completely Randomized Design (CRD) with three treatments and six replications to obtain 18 experimental units. The tuba root plant trial test consists of 3 levels: root extract, branch extract, and leaf extract with organic solvents. The parameters observed were the time of death of brown planthopper (hour), lethal meantime (LT50) (hour), daily mortality (%), and total mortality (%). The results showed that the application of root extract caused an initial death of 2.33 hours after application, LT50 17.33 hours after application with a total mortality rate of 100%. Application of botanical insecticide tuba root is effective for controlling brown planthopper pests in rice plants because it causes the death of brown planthopper above 80%.
