Achievements, Findings & Experience


Research & Development (R&D)


Infrastructure Development Project

“Establishing Arachnnarium at TFRI, Jabalpur, MP”. Funded by MP State Forest Department. (2015-2018)


Under this project an Arachnarium was established at TFRI which is for the first time in India. The unit is composed of a spider interpretation centre, a spider rearing laboratory and a spider garden where live spiders can be observed in different microhabitats including aquatic niche for fisher-eating spiders. The air of the unit was to eliminate arachnophobia from the mind of the people and to extend the role of spiders as bio-control agent.


Applied Research Project

“Determination of biocontrol efficacy of spiders against insect pests of rice agroforestry system” in collaboration with Entomology unit in College of Forestry of Jawaharlal Nehru Krishi Vishva Vidalaya (JNKVV), Jabalpur. (2018-2022)

The project encompasses the probability of utilizing spiders a predator to control major insect-pest of rice. Emphasis was imposed on the use of social spider Stegodyphus sarasinorum by mounting its communal nest on specially designed bamboo-pole-trap among rice field. The success would measured by comparing harvest from control field and treated field where spider used as biocontrol agent. The project in progress.



Management of Indian Gypsy Moth (Lymantria obfuscata) in Himachal Pradesh (2008-2013)

The native strain of baculoviral occluted bodies were harvested, centrifuged to get pure crystals and purified in 1%SDS. The viral crystals were imaged under a high resolution Transmission Electron Microscope (TEM) at Nano Particle Laboratory of IIT, Delhi. The viral occluded bodies were identified as LOMNPV having a taxonomic code of and verified through ICTVdB Management for Baculoviridae of Universal Virus Database V.3 at Columbia University, N.Y. USA. The pure virus crystals were enumerated and serially diluted for a series of bio-assay studies to get LD90 to kill larvae of Indian Gypsy Moth.



Predatory efficiency of social spider Stegodyphus sarasinorum Karsch (Arachnida: Araneae:Eresidae) against insect pests of Plants in Forest Nursery. (2010-2013)

To mount biocontrol measures utilizing the predatory social spider Stegodyphus sarasinorum in the nursery, study of “Life Cycle & Biology” of the spider was realized necessary and this study was completed within 2 years. The result indicates that each female produce on 1-2 egg-case containing about 100-150 eggs in each. These eggs hatch in 20-25 days and spiderlings emerge out of the egg-case in 30 days. There are 12 instars of the spiderlings to become adult and only at the end of 12th instar the sex can be determined. An improvised devise made of locally available hill- bamboo, for colony establishment of social spider, was made and used as live-trap for pests of forest nursery. Experiments on the magnitude of prey captured and extent of predation by the spider were evaluated.



“Development of ecologically viable and socio-economically acceptable integrated models for arresting willow (Salyx spp.) mortality in Lahaul valley of Himachal Pradesh”: funded by GB Pant Institute of Himalayan Environment & Development. (2002-2005).

Findings: Surveyed different localities of Lahaul and Spiti and screened affected willow trees. Enormous infestion of two species of aphids, viz. Giant willow aphid (Tuberolachnus salignus) and Black willow aphid (Pterocomma salicis) (Aphidoidea:Lachnidae) were detected on dying trees. Moreover fungus infestation by Cytosperma chrysospermus was also detected from the roots of the tree. The large scale mortality was attributed multiple factors combined: very old planting stock date back to 1880, monoculture, sites are deprived of water flow, trees planted around crop-field and households, domestic and public drains made of concrete, sites grazed by cattles, improper silvicultural technique, and indiscriminate lopping, raise in temperature, melting of glaciers and low snowfall. New pest resistant clones from Solan and from Finland were procured and planted in the Lahaul valley.



Standardization of methodology for seed collection, seed handling, storage and breaking seed dormancy in Juniperus polycarpus and Fraxinus xanthoxyloides. (2010-2013)

Entomological Study: Pattan Valley and Lahaul Valley were surveyed and Juniperes polycarpus were screened for cone borers, 65% of the collected cones were found to be infected. 3 different species of microlepidopteran moths of the family Gelechidae were found to be the major seed borers. 2 species of phytophagous hymenopteran parasites were also found to be the cone borer, viz. Megastigmus dorsalis and Torymus sp. 1 species predatory spider were recorded: Stetoda sp. (Theridiidae). Suggestion was given to nursery managers to use this parasite for seed pest control.



Bioecological studies on the predatory efficiency of certain carnivorous Lepidoptera of Assam. (1995-1998)

One species of carnivorous butterfly & two species of moths found to be predators of coccids and aphids. Larvae of these lepidoptra are plant feeders but this unique phenomenon were rediscovered after 100 years of their existence were noticed. Spalgis epius (Lepidoptera:Lycaenidae), a blue butterfly, Eublemma coccivora (Lepidoptera:Noctuidae) and Conobathra aphidivora (Lepidoptera:Pyrallidae), two months, exhibit peculiar and remarkable carnivorous habit during their larval stages and can be utilized for biological control measures.



Internationally funded project

FREEP Project 3 of 4: Shifting Cultivation IRMDFR, Jorhat

  1. Monitor physical and chemical changes in soil properties before and during shifting cultivation cycles;
  2. Examine changes in micro-flora, including mycorriza due to shifting cultivation.
  3. Develop ecologically compatible alternatives to shifting cultivation.

Project implemented as PI: Studies on the microfaunal components of litter ecosystem and their changes in relation to shifting cultivation (project No. IRMDFR/FE/2):

Findings: Litter microfauna of different fallow periods under shifting cultivation were assessed. The comparison reveled that natural forest litter fauna remains more or less stable in population density. Whereas due to change of plant community in different fallow period, the litter fauna varied attributed to the establishment of all trophic levels within detrivore food chain. Above all the rich and diverse microfauna highly contribute to the leaf-litter decomposition for a better growth of plant community.



UNDP-ICFRE Project on Strengthening and Development of ICFRE: 1993-1995

This five years long project was launched on 4.9.1992 with UNDP assistance of US $ 2.56 million and Indian contribution of Rs.21.94 million. The main aim of the project is to strengthen the capacity of ICFRE Institutes and their personnel to undertake and extend forestry research.

As a new recruitee I was attached with the survey team for socio-economic survey of villages in different northern states of India. The work entrusted was to review the status of villagers living within or adjacent to protected area network, where they are partially dependent on wood and non-wood forest produce. Involved in summarizing results and reports for the project.



ICFRE-IDRC Research Project on Himalaya Eco-rehabilitation (1993- 1996)

Initiated in April, 1993, this project aims at locating and quantifying, the damages caused by common land use practice in the Himalaya such as mining and shifting cultivation by using GIS techniques and developing socio-economically viable and ecologically stable methodologies for rehabilitation of degraded areas by application of well tested agro forestry techniques developed at ICFRE.

In this project also I was attached with the survey team to prepare sustainable methods as an alternative to shifting cultivation. Joined the team for eco-rehabilitation of coal-mine areas of Margharita in Tinsukia of Assam. Involved in summarizing results and reports for the project.


Exploratory & Academic Project

Natural enemy complex of key and potential pests of 5 Quercus spp. Of Himachal Pradesh (2002-2005)

Findings:  Five species of oaks,  viz.  Quercus glauca, Q. lecotrichophora, Q. dilatata, Q. semicarpifolia & Q. ilex were found to be vulnerable of pest attack. 10 species of insect pests and one species of mite were found to be very destructive pests. Among these Indian Gypsy Moth (Lymantria obfuscata), Chafer beetle (Holotrichia longipennis) and Oak acorn weevil (Curculio sikkimensis) were major pests. 3 new species of hymenopteran parasites of gall forming pests viz. Torymus himachalicus, T. stom, & T. absonus were discovered. 22 Predatory spiders were found feeding on different pests infesting oaks. A new native strain of baculovirus, namely Lymantria Obfuscata Nuclear Polyhedrosis Virus (LONPV) were also isolated. Biology of Indian Gypsy Moth was studied in full indicating its winter hibernation as well as survival under snow during egg-stage. From the natural forests of Sirmour district, where there were several outbreaks

of IGM, a native strain of baculovirus were recorded from the diseased larvae.



Key and potential insect pests of bamboos and their natural enemy complex. (1994-1999)

Findings: 5 species of bamboos viz, Bambusa tulda, B. palida, B. balcooa,

B. nutan and Thrysostachys oliveri were selected, screened and studies of their pests and biocontrol agents. 34 species of pests belonging to Orthoptera,   Lepidoptera,   Homoptera,   Coleoptera  and   Hemiptera were detected. Out of these, Discophora tullia a lepidopteran defoliator, Crocidophora sp. Pyrallid leaf roller, Callispa sp. a coleopteran window defoliator, Pseudoregma bambusicola and Astegopteryx bambusae, two aphids were found to be the key and potential pests. 11 species of parasites and predators were detected as natural enemies. Two hymenopteran parasites, viz, Cheiloneurus sp. and Perochilomerous sp. Oviposit on coccids. 6 species of spiders, viz. Nephila pilipes, N. kuhlii, Neoscona bengalensis, Gasteracantha didesmia, Hylus secupreus and Plexippus paykulii were polyphagous and very effective in the nursery.



Bio-ecology of gall aphids (Homoptera:Aphididae) infesting Styrax serrulatum (1995-1998)

Two types of leaf-galls were found on Styrax serrulatum. The galls, namely, “Coral Gall” and “Banana Gall”, are formed due to infestation of aphids on the leaf buds of the plant and so far a new record from north east India. Taxonomic study indicates that there are two species of aphids associated with these gall formation, viz. Astegopteryx bambusae and A. styracicola. Study revealed that these aphids exhibit host alternation and their alternation of generation occur between Styrax and bamboo. In this research, biometry, biotaxonomy, ecology, alternation of generation, gall morphology, development of gall and natural enemy associated with these aphids were studied.



Coccinellid beetles as predator of aphids (1993-1995)

Laboratory based prey-feeding study on biological control of bamboo- infesting aphid Pseudoregma bambusicola using coccnellid beetle Adalia septempunctata was completed. In this study predatory efficiency of the different larval stages as well as adult itself were evaluated. It was found that the beetle is an effective predator of bamboo infesting aphids.


Research Activity (Non-Plan)

Ornithological Study

  • Registered participation and collaboration of TFRI with the global ornithological survey of Cornell Lab. Of Ornithology, Cornell University, NY, USA. Institutionalized campus bird count of TFRI on the global platform through online eBird portal. Since 2016 4 day survey resulted occurrence of 172 bird species in the TFRI campus. This was the first such survey made in any ICFRE institutes since 2016. Significant findings were occurrence of Fire caped tit, Crow billed drongo, White browed bulbul, Black winged shrike and Orange breasted green pigeon, which were first such record from central India.
  • Initiated a work on “Frugivorous avifaunal diversity associated with Bridelia retusa and bird mediated seed germination”. Only 20% germination was reported for the tree in nursery but using bird-mediated- seed technique, germination of seed raised to 57%. This technique may be practiced to get better germination for some difficult seeds that fail in the nursery.


Taxonomic Database

Since last one decade I was working on the preparation of database of Indian Spiders. Using Microsoft Access program, the template for the database was structured and records of more than 1500 species of Indian spiders were digitized. Apart from taxonomic data, distribution and bibliography were also appended into the information. The database is searchable and report can be generated as desired by user. No such database is available for Indian spiders, and this would be launched in ICFRE website as soon it is complete in 2019.




The followings are findings on spiders:

  1. A new species of spider was discovered from Shimla viz. Episinus himachalicus
  2. Nilus albocinctus, a fish eating spider was recorded for the first time from M.P. Biology of the species were studied
  3. Cyrtarachne ixiodes, found to be a new record from Indian subcontinent and a new record
  4. Biology of giant wood spider, Nephila pilipes were studied and its oviposition and oviposition site were recorded which was unknown from India.
  5. Moreover 12 species of spiders added to the fauna of M.P. Noteworthy to mention were a new species of Bomis and Makdiops.
  6. The deadly and lethal Indian Red-Back Spider, Latrodectus hasselti (Indian Black-Widow) was discovered from Jabalpur which was a new record.
  7. New distribution record of colour changing spider Gea spinipes recorded from hills of Sarahan.
  8. Nesticidae, a family of spiders which was not so far not represented in India, was detected from caves of Kullu. 2 new species were discovered. Publication awaited due to transfer to other institute.
  9. Standardized laboratory rearing technique for Himalayan Silver Knee Tarantula (Haplocosmia himalayana), that is endangered due to its habitat loss in the hills.



Reassignment of Forest Types of India
