“…The minimum temperature, relative humidity and rainfall proving negative relationship with population of S. litura infesting groundnut crop. Similarly, Yadav et al, (2015) [6] in black gram also reported that population of S. litura showed non-significant negative correlation with rainfall and wind velocity while temperature (minimum and maximum), relative humidity (morning and evening) and sunshine showed a non significant positive correlation. Similarly, Brahman et al, 2018 [3] in soybean also reported that population of S. litura showed significant correlation with maximum temperature (r= 0.663), whereas negative significant correlation was noticed with rainfall (r = -0.570).…”

The field experiment were conducted at Research Cum Instructional Farm at IGKV, Raipur (C.G.) during kharif 2018, to know the seasonal incidence of fall army worm, Spodoptera frugiperda infesting maize crop. Fall army worm, Spodoptera frugiperda appeared during 37 th SMW i.e. 2 nd week of September with a mean population of 0.12 larva/plant. The peak population were observed in the fourth week of September with a mean population of 0.56 larva/plant. Thereafter, the population declined gradually and reached to a minimum level of 0.16 larva/plant during 4 th week of October (42 nd SMW). The correlation between fall army worm, Spodoptera frugiperda and abiotic parameters during kharif 2018 results indicated that the population demonstrated a significant positive correlation with maximum temperature (r=0.586).

“…Srivastava and Prajapati (2012) reported that maximum temperature exhibited significantly positive correlation while mean relative humidity and rainfall were showed negative correlation with whitefly population on blakgram. In contrast, Yadav and Singh (2013) reported negative correlation with maximum temperature on the influence of whitefly activity on mungbean. Srinivasaraghavan (2014) also recorded positive correlation between maximum temperature and whitefly population, whereas significant negative correlation was recorded between whitefly population and morning relative humidity.…”

An investigation was conducted on population dynamics of whitefly, Bemisia tabaci and incidence of mungbean yellow mosaic India virus (MYMIV) on blackgram during Kharif 2015-16. observations of adult whitefly was recorded at weekly interval through yellow sticky trap at the field by installing just above the crop canopy for 24 hours and percent disease incidence of MYMIV was recorded. Results revealed that the whitefly was first observed from 28 th SMW (15.83 whiteflies sticky trap-1). During this period maximum and minimum temperature was 30.4 0 C and 24.2 0 C while morning and evening RH were 91% and 74%, respectively. Further, wind speed, sunshine, rainfall and rainy days were observed 7.3 (kmh-1), 6.8 (hrs), 203.2 (mm) and 6 (days), respectively. The whitefly population was reached at its peak (67.83 whiteflies sticky trap-1) at 36 th SMW. Correlation studies with maximum temperature was exhibited significantly positive (r=0.659), whereas wind speed (r=-0.812) and rainfall (r=-0.809) were showed highly negative significant association with whitefly. Path analysis revealed that evening RH had highest direct positive effect (1.4106) on whitefly followed by maximum temperature (1.0663), sunshine (0.0675), rainfall (0.0501) whereas, direct negative effect was exerted via rainy days (-0.6289) followed by wind speed. The first incidence of MYMIV (2.35%) was recorded on blackgram at 30 th SMW which was gradually increased and reached at peak (100.00%) on 36 th SMW. Maximum temperature showed significantly positive correlation (r=0.630) with incidence of MYMIV. Results revealed that severe attack of whitefly was occurred as pest outbreak and MYMIV incidence as epidemic form on blackgram due to erratic abiotic factors.

“…Nitharwal and Kumawat (2009) found a significant negative correlation of jassid, whitefly and thrips with maximum temperature and positive correlation of thrips with minimum temperature. Yadav and Singh (2013) found a significant negative correlation of spotted pod borer with minimum relative humidity and positive correlation with sunshine and evaporation.…”

The study was conducted to know the abundance of aphid, flea beetle and pod borer on the mutants viz., MBM-07-Y-1, MBM-07-Y-2, MBM- 656-51-2, MBM-527-114, MBM-07-(S)-2, MBM-347-13, MBM-390-94-Y, MBM-427-87-3, MBM-80 (Local) and a variety BARI moog-6 and the role of weather parameters on the population dynamics of insects at the Agricultural Farm of Patuakhali Science and Technology University from April to June, 2015. Results revealed that the tested mutants did not show resistance against aphid, flea beetle and pod borer. Mutant MBM- 347-13 had the lowest number of flea beetle while mutant MBM-427-87- 3, MBM-80(LCAL) and MBM-527-114 had the highest number of flea beetle indicating higher susceptibility to flea beetle. Mutant MBM-390-94- Y had the lowest abundance of aphid while BARI moog-6 had highest aphid abundance. Mutant MBM-347-13 had lowest number of pod borer and MBM-427-87-3 had highest abundance of pod borer followed by MBM-07(S)-2 and BARI moog-6. Flea beetle abundance gradually increased with decreasing average temperature while aphid and pod borer abundance gradually increased with increasing average temperature. In case of humidity, flea beetle abundance increased very slightly with increasing average humidity but aphid abundance increased very slightly with increasing average humidity. Pod borer abundance was low with high average humidity and then increased slightly due to decrease of humidity and finally declined with increasing humidity. SAARC J. Agri., 16(2): 1-12 (2018)
