White grubs are highly polyphagous and most destructive soil pests inflicting damage to a wide variety of crops. In India, more than 1000 species white known which over 40 attack range plants. naturally infected by various entomopathogens include fungi, bacteria nematodes. Entomopathogenic fungi offer great potential members genera Beauveria Metarhizium widely used against grubs. Several commercial products entomopathogenic like Bio Green, ORY-X, Grub X 10G, Betel, Biotrol FMA Meta-Guard...
Brahmina coriacea (Hope) is the most widely distributed and destructive species of white grubs having potential to inflict 40-50 per cent yield losses potato in Himachal Pradesh. The efficacy two local isolates Beauveria brongniartii (KH I KH II) was evaluated against B. by dip treatment oral feeding methods. Against first second instar grubs, proved be highly effective, whereas for third through showed higher virulence. LC50 values II were 2.55í—105 conidia/ml 2.80í—105 treatment, method,...
Biological and behavioural characteristics of Diaeretiella rapae were studied in a laboratory using Lipaphis erysimi as host. The total developmental period the parasitoid was longer early instars compared to that later instars. Host age at time oviposition affected period, post-oviposition fecundity parasitoid. Survival immatures higher older than younger sex ratio for found be female-biased. Adult longevity D. females when males. mean adult while parasitizing nymphs groups (1–2 days) (4–5...

 Effect of climatic factors on population build-up aphid complex rapeseed-mustard viz. mustard aphid, Lipaphis erysimi (Kaltenbach), cabbage Brevicoryne brassicae (Linnaeus), and green peach Myzus persicae (Sulzer) associated natural enemies (coccinellids, syrphids a parasitoid, Diaeretiella rapae M’Intosh) was studied at Experimental Farm CSK HPKV Palampur over period three years. Correlation coefficients indicated that the temperature favoured their while rainfall exerted negative...
Abstract Three parasitoid species viz . Aphelinus asychis Walker (Hymenoptera: Aphelinidae), Aphidius ervi (Haliday) Braconidae) and Diaeretiella rapae (McIntosh) parasitizing the aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae) in mid-hills of north India were studied. At different locations times year, parasitization by A , D ranged from 7.53 to 37.58, 4.26 80.45, 74.25 80.48%, respectively. All 3 parasitoids successfully completed their development on nymphal instars host total...

Abstract We studied the impact of weather parameters on population build-up Brevicoryne brassicae (L.) (Cabbage aphid), Lipaphis erysimi (Kalt.) (Mustard Myzus persicae (Sulzer) (Green peach aphid) and their biocontrol agents (coccinellids, syrphids, a parasitoid, Diaeretiella rapae M’Intosh) oilseed brassicas in Himachal Pradesh, India, during winters from 2016–2017 to 2018–2019. The temperature sunshine resulted B. agents’ population, while rainfall relative humidity caused negative...
