Abstract

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.

Abstract

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.

Abstract

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

Abstract

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.

Abstract

Doon valley, because of its location peculiarities, encompasses a rich floral and faunal diversity. Family Eulophidae (Hymenoptera: Chalcidoidea) comprises of lesser known microscopic parasitoid insects which help in controlling the populations of mainly various lepidopterous insect of forest plants. Present study was conducted to assess the occurrence of eulophid species in Doon valley and to provide baseline informative inventory for further biodiversity and taxonomic studies. In the valley Eulophidae is represented by 17 genera and 45 species. Forest habitat was found to be the most diverse in number of genera and species followed by agriculture and horticultural land uses. A total of 31 species were collected from agriculture habitat, 23 from horticulture habitat and 45 species from forest habitat.

Abstract

Sesame (Sesamum indicum L.) is an oil seed crop of Indian origin. Its oil content varies from 45-63 per cent with an average of 54 per cent whereas protein content varies from 17-32 per cent with an average of 26 per cent. Fat free meal has been reported to contain about 60 per cent protein, rich in sulfur containing amino acids.

Abstract

Adders are key components of digital design and are necessary part of any digital signal processor (DSP) and microprocessors. Addition is representative of many arithmetic processing operations that must be carried out in portable digital systems[13,14], and the speed and power consumption trade-offs in adder hardware are of interest to portable digital system designers. Apart from the basic Addition they also perform other operations such as Subtractions, multiplication, division, address calculation[1]. Adders of various bit widths are frequently required in Very Large Scale Integration (VLSI) circuits from processors to Application Specific Integrated Circuits. In most of these systems the adder lies in the critical path that determines the overall performance of the system. In this paper, different type of 8-bit full adders are analyzed and compared for transistor count, power dissipation, delay and power delay products. The investigation has been carried out with simulation runs on Tanner environment using 180nm&90nm CMOS process technology at 2V. The result shows that the carry skip adder has the lowest power-delay product.

Abstract

Insect pests and diseases can cause serious damage to natural/man-made forests. Many records on such losses have already been reported worldwide. Therefore, the solution should focus on keeping the pest/pathogen population at low levels, which will not interfere with the management objectives. A seminar on current challenges in the management of forest insect pests and diseases was held recently. Fifty-seven delegates, including eminent scientists, researchers, academicians from colleges and universities, farmers and personnel of the State Forest Departments (SFDs) participated in the event. The seminar aimed to share knowledge and ideas on the available techniques and technologies for the management of forest insect pests and diseases.
