Abstract White grubs are known as the “National pest” of India due to their wide distribution and economic damage. Brahmina coriacea restricted Tibet, China Himalayan region in Jammu Kashmir, Himachal Pradesh Uttarakhand. The B. were collected from soil Solanum tuberosum , Zea mays Pisum sativum Rosa rubiginosa Phaseolus vulgaris Malus pumila Pyrus communis different ecosystems eight locations Pradesh, India, by pit sampling method. identified examining raster pattern. There was variation...
Termites are polyphagous pests causing economic losses to a large number of crops worldwide. Among 3105 species termites, about 185 considered as globally. The termites that belong family Termitidae known cause great agricultural and horticultural crops. In India, Odontotermes obesus (Rambur) Microtermes obesi Holmgren damage in both vegetative reproductive stages, especially wheat, maize, barley, pulses, oilseeds, vegetables, fruits, plantations, sugarcane, cotton etc. can lead almost 100%...
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...
White grub, Brahmina coriacea (Hope), is widespread in northwestern India, invading the areas with temperate and sub-temperate climate. Both adults grubs are polyphagous pests. Apple potato were severely ravaged by of B. coriacea, respectively. The species was most prevalent at Shillaroo, Kheradhar, Kullu, Kwagdhar, Reckong Peo, Nauni Bharmour. recorded on 15 host plants from region, but apple (18.7–87.9%) walnut (28.1–93.7%) preferred most. However, damaged tubers during September–October...
The Rayleigh-Taylor instability of two supersposed couple-stress fluids uniform densities in a porous medium the presence horizontal magnetic field is studied. For mathematical simplicity, stability analysis carried out for highly viscous equal kinematic viscosity and viscosity. A potentially stable configuration remains under certain conditions, unstable conditions. stabilizes wave-number range k>k*, which absence field.
The efficacy of three Heterorhabditis spp entomopathogenic nematodes (EPNs) from north western Himalaya, India was studied against the larvae pod borer, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), under laboratory conditions. were exposed to 10, 20, 30 and 40 infective juveniles (IJs) each nematode species for different time periods they found be susceptible all EPNs tested. However, susceptibility infection varied according concentrations IJs their exposure periods. these...
The present study deals with the impact of temperature on development, survival, reproduction and population growth a recently invaded most destructive pest tomato, Tuta absoluta (Meyrick) aim to understand its possible expansion in different agro-climatic zones. Though T. was able develop between 15° 35°C, around 25°-30°C more suitable. Survival fecundity were highest at 25°C lowest 35°C. Developmental threshold for developmental stages varied from 6.2 9.5°C, while thermal constant required...
ABSTRACTTea is being grown on the gentle slopes of Himachal Pradesh located in north-western region mighty Himalaya, since 1850s. However, degrading soil health due to rampant usage agrochemicals, and long-run tea cultivation adversely affects productivity potential region. Analyzing soil-nutrient status great value meet crop nutrient demand. The research aimed identify vulnerable properties their assessment for restoration under major estates North-western Himalaya. study examined...
Himachal Pradesh is a northern state of India and situated to the southern mighty Himalaya. The agro-climatic conditions are conducive for production off-season vegetables. Biological control by entomopathogenic nematodes (EPNs) one alternatives manage turnip moth, Agrotis segetum (Denis & Schiffermuller) (Lepidoptera: Noctuidae). present study was, therefore, undertaken with objective assess virulence local EPN isolates from Pradesh, Heterorhabditis sp., against pests minimize use...
It is imperative to develop integrated fertilization strategies for various forage crops that enhance the competitive ability of crop, increase crop production and reduce risk nonpoint source pollution from fertilizers. The objectives this study were determine effect different sources nutrients on performance sorghum sudan grass hybrid-oat cropping system. Significantly highest plant height, shoots per square meter, leaf stem ratio dry matter accumulation hybrid oat was observed with FYM @10...
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,...
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most destructive pests tomato, has recently invaded India. Before recommending any bio-control agent for its control, it is important to study demographic parameters bio-agent on pest. The present evaluates indigenous trichogrammatids namely Trichogramma achaeae Nagaraja and Nagarkatti, T. pretiosum Riley, chilonis (Ishii), pieridis Prashanth against this pest, aiming select effective egg parasitoid species. Significant...
