Abstract

Under both the condition of this study, the forest land has higher initial infiltration rates of 46.8 cm/hr and 5 cm/hr and final infiltration rates of .1 cm/hr in 150 mts and .1 cm/hr in 120 mts from forest areas as compared to .1 cm/hr in 60 mts ond 0 cm/hr in 20 mts from agricultural land after snow removal and snow melt respectively, due to thick layer of humus(10 cm) beneath the forest cover; higher organic matter (7.27%), higher moisture equivalent (29.87%), higher pore space (61.60%) and hIgher water balding capacity (60.26%) forest soils hafe resulted in higher infiltration rates in comparison to the agritultural soils, with no humus, low organic matter content (2.68%), lower moistnre equivalent (29.8%), lesser pore space (56.6%) and lower water holding capacity (46.88%).

Abstract

The forester is faced continually with insect problems at every stage of the growth of the tree. On an average the insects cause a loss of roughly Rs. 100 per annum per square mile over workable forests and this gives the total loss caused by forest insects as Rs. 125 lakhs. Before undertaking control of the pest, one should know the ecology and dynamics of the insect populations. The control methods adopted are too varied, or sometimes limited in application. Modern insecticides create in due course new complications, Some important and major examples are cited to illustrate the integrated control measures adopted in India.

Abstract

Two small forest (brush) Watersheds W₁F (1.45 ha) and W₂F (0.87 ha) were calibrated for 8 years (1961-68). During calibration period W₁F gave 18% more runoff and 63% higher peak rate of runoff as compared to W₂F. In the year 1969, W₁F was clearfelled and reafforested with Eucalyptus species. The post calibration relationship indicates that W₁F (treated) after afforestation gave 10% less runoff and peak rates of runoff as compared to W₂F (untreated). The total reduction of 28% in runoff and 73% in peak rate is due to afforestation resulting in fully stocked plantation and a dense undergrowth. The study has quantitatively indicated the effectiveness of afforestation for flood control purposes by reducing runoff (28%) and of drastically reducing the peak rate of runoff (73%).

Abstract

The larval characters of Gibbium psyllioides Czempinski (Ptinidae, Coleoptera) are described, with figures. Its larvae were collected while crawling on a glass plate of the laboratory bench at the Forest Research Institute, Dehra Dun. They were perhaps subsisting on the faecal matter of squirrels, bats, lizards, etc.; present on the wooden ceiling and had fallen down through the chinks. Brief review of literature on the larval characters of other species of Ptinidae is also included.

Abstract

The chief host of Atractocerus reversus is Boswellia serrata (salai) but Lannea grandis has also been recorded. Other new hosts are Buchanania latifolia, Butea frondosa, Cochlospermum gossypium and Hardwickia binata. The beetles begin to emerge from February at Nepanagar, M.P. and from March at Dehra Dun, U.P., depending on the weather conditions.

Abstract

Govt. of India started Technician Education Project I&II with massive World Bank assistance of Rs. 2000 crores. Encouraged by the success of this project, World Bank sanctioned the following projects: Technician Education Project III and TEQUIP (Technical Education Quality Improvement Program) for degree level engineering institutions. The objectives of TEQUIP Program are described at the outset. Criteria for selection of States and engineering institutions therein are discussed in detail. In June 2004, TEQUIP Program was revised to overcome the initial reverses and to put the project back on rails. A separate agency NPIU (National Project Implementation Unit) was constituted to keep track of progress of the project. The progress of the project under supervision of NPIU is described in the paper.
