Hayat and Kazmi (1996) described encyrtid species Proleurocerus litoralis from the sweep collected material from Kerala. In the present study Proleurocerus litoralis have been recorded from the Doon Valley in northern India. It was bred from egg masses of Eurybrachys tomentosa (Homoptera: Fulgoridae) which forms the first host record of the species. This species was earlier known by its females only; in the present study male of this species have also been described in details.Keywords

Gmelina arborea (Roxb.) has gained widespread acceptance as a plantation species worldwide due to its rapid growth and multiplicity of uses in pulp and fiber production, besides an excellent saw timber has number of promising attributes. The strategy for addressing a major drawback for its susceptibility to Craspedonta leayana (Latreille) in native areas has been discussed. This includes mass multiplication and application of parasitoid Brachymeria excarinata, Beauveria bassiana and Metarhzium anisopliae. The screening of resistant germplasm for Craspedonta leayana was found to be an effective long term strategy.- Planting Stock Improvement in Gmelina arborea

The planting stock of Gmelina arborea was improved through 'Technology Mission - Gmelina arborea'. The mission incorporated various techniques of genetics, breeding, clonal propagation, nursery, physiology, phenology, entomology and pathology. A total of 119 plus tree selected from 10 geographical locations were selected and multiplied through clonal means, and established in the vegetative multiplication gardens cum germplasm banks. The passports for plus tree was developed that provided information on different aspects including species, accession, geography, silviculture and technical information. The vegetative propagation protocols both for adult and juvenile materials were standardized using budding, grafting and ischolar_maining of branch cuttings. The clonal and progeny trials were carried out to test the stability, adaptability and growth performance of selected germplasm. The seedling and clonal seed orchards were established in the states of Assam, Manipur and Tripura to meet immediate supply of the improved seed. Various clones were screened for resistance against Craspedonta leayana which is a serious defoliator of G. arborea. Eight per cent of the clones exhibited higher resistance while 26 per cent of the clones showed moderate resistance. The seed treatment with fungicide Captaf was found to be most effective in managing seed and seedling fungal pathogens- Updation and Digitization of Buprestids (Coleoptera: Buprestidae) Type Collection of National forest Insect Collection (NFIC), FRI, Dehradun (INDIA)

Buprestid type collection has been studied and updated at National Forest Insect Collection (NFIC), Forest Research Institute (FRI), Dehradun, India. Buprestids in NFIC are represented by 11 subfamilies, 14 tribes, 15 genera having 54 holotypes 22 paratypes of 71 species. In the present contribution 71 insect specimens belonging to family Buprestidae their subfamilies, tribes with male and female of Holotypes and Paratypes are digitized alongwith coloured photograph of each specimen taken with automontage3-D imaging system for long term use.Keywords

Termitoloemus marshalli Baranov (Diptera: Calliphoridae: Bengaliinae) was known to the science only through one male holotype and two female paratypes collected from Kanpur (Uttar Pradesh, INDIA) in 1935. Since then no specimen was ever captured or identified by any worker. In the present paper its rediscovery after 78 years is reported. It was found predating voraciously on the workers and soldiers of the termites Odontotermes obesus and O. giriensis in Assam and in Dehradun. Material identified is deposited in National Insect Reference Collection, FRI, Dehradun and shall also be deposited with other national and international insect depositories so that the species may be well understoodand exploited for termite biological control initiatives.Keywords
