“…The present findings agree with Rana et al(1995), who reported that both Coccinella septempunctata and L. erysimi were inversely related to each other, and at a time, the population of one increased, while the other decreased, resulting in a synchronization. On the other hand, Talpur and Khuhro (2004) reported that coccinellid beetles appeared at the later stage of the crop when there was the maximum population of B. brassicae aphids on the crop, confirming our results. Furthermore, the data on the relationship between aphid population and percent parasitization revealed that the activity of D. rapae was influenced by the presence of the aphid population in the field.…”

We studied the impact of weather parameters on the population build-up of Brevicoryne brassicae (L.) (Cabbage aphid), Lipaphis erysimi (Kalt.) (Mustard aphid), Myzus persicae (Sulzer) (Green peach aphid) and their biocontrol agents (coccinellids, syrphids, and a parasitoid, Diaeretiella rapae M’Intosh) on oilseed brassicas in Himachal Pradesh, India, during winters from 2016–2017 to 2018–2019. The temperature and sunshine resulted in the build-up of B. brassicae and their biocontrol agents’ population, while rainfall and relative humidity caused a negative influence at surveyed locations. The L. erysimi and M. persicae populations showed an inverse correlation with the density-independent factors at most locations. Correlation coefficients indicated a negative correlation of the coccinellids population with the build-up of L. erysimi and M. persicae, while the predator population was positively related to the B. brassicae population at maximum locations. Parasitization by D. rapae showed a negative relationship with the aphid population. Stepwise regression analysis showed that minimum temperature and rainfall had a significant effect on the variability in the population of aphids. The predictive model could interpret more than 90% variation by minimum temperature in the coccinellid population at the surveyed locations. Further, regression analysis with temperature could explain up to 94% variability in parasitization by D. rapae. This study will contribute to predicting the changes that may occur in a population of aphids concerning the weather.

“…The peak activity of aphids was recorded during 7 th -8 th SMW on most of the genotypes. Talpur and Khuhro (2004) also observed that mustard aphid appeared on leaves during 3 rd week of January and on the inflorescences during 2 nd week of February and continued up to harvesting. Ansari et al, (2007) also observed that natural appearance of mustard aphid on Brassica germplasm occurred on 11 th January (60 DAS) and disappeared after 2 nd March (110 DAS).…”

“…However, appearance of coccinellids at later stage of the crop with maximum population of B. brassicae was favourable for coccinellid predators. Talpur and Khuhro (2004) also reported that coccinellid beetles appeared at later stage of the crop when of crop growth, counts were made on whole plant, whereas, after stem elongation, terminal 10 cm of the apical shoot formed the sampling unit. ; € Average of 50 observations £ Coccinellids = number of adults and grubs per plant; Syrphids = number of larvae per 10 cm apical twig; D. rapae = per cent parasitization there was maximum population of aphids on the crop.…”

Effect of climatic factors on population build-up of aphid complex of rapeseed-mustard viz. mustard aphid, Lipaphis erysimi (Kaltenbach), cabbage aphid, Brevicoryne brassicae (Linnaeus), and green peach aphid, Myzus persicae (Sulzer) and associated natural enemies (coccinellids, syrphids and a parasitoid, Diaeretiella rapae M’Intosh) was studied at Experimental Farm of CSK HPKV Palampur over a period of three years. Correlation coefficients indicated that the temperature favoured build-up of aphid population and their natural enemies while rainfall exerted negative impact. The population of coccinellids was negatively correlated with the population of L. erysimi and M. persicae while, positive correlation with B. brassicae was observed. On the other hand, population of syrphids was found to be positively correlated with aphid population. Predictive model using stepup regression analysis revealed that a weak relation in aphid population was attributed by weather parameters particularly minimum, maximum temperature and bright sunshine hours. Regression analysis revealed that 89 per cent variation in parasitization by D. rapae was attributed by minimum and maximum temperature, rainfall, relative humidity and bright sunshine hours.
