Abstract

Plants constitute basic elements in the biosphere fabric and the continuous interaction of insects with plants. The secretion of some chemicals by plant forces insects to change their habits. In this paper such changes have been discussed for exploitation of these types of chemicals in developing ecologically compatible pest management.

Abstract

The study of mortality - its level and trend - is very important from more points than one. Mortality being an important component of population change, any study on it is of use to the demographer, planner and others. Study of mortality is also of vital importance to the public health, authorities and health planners, especially if mortality statistics are available by several characteristics such as age, sex and cause of death.

Abstract

The analysis of 280 soil samples collected from jute and pulse fields from Nadia and Murshidabad districts of West Bengal during July 1997 and January, 2000 indicates that among microarthropods present per unit volume of soil, mites were the dominant in number both in jute (78%) and pulse (73.33%) and this was followed by the collembollans (21.33%) and (22.66%) and others (0.67%) and (4.01%) in jute and pulse correspondingly. In respect of the nematode population dorylaimids were numerically dominant in both jute (50%) and pulse (45.7%) and this was followed by rhabdoids and tylenchids in jute 34% and 16% and in pulse 31.82% and 22.48% respectively. Among the tylenchids, the population of Hirschmanniella sp. and Helicotylenchus sp. was higher in jute and the population of Tylenchorhynchus sp. was higher in pulse. The pH, soil temperature and soil moisture content of the soil samples were recorded. It appears that the moisture content of the soil has some positive effect on the population structure of microarthropods and nematodes both in jute and pulse.

Abstract

Power transmission and distribution can be done either by overhead lines or power cables. Although overhead lines have been most reliable for many years, the deregulation of the electricity supply markets and growing environmental awareness are creating exciting new markets for power transmission solutions based on underground cable technology. Although there are different constructions for high-voltage cable systems this paper only deals with the following essential parts: conductor, semi conductive shielding, insulation and sheathing. This information is provided as a tool which can be utilized by electric utility engineers to improve power system performance.

Abstract

The Krishi Vigyan Kendra of districts of Chhattisgarh state were selected for the study purpose because these KVK are the oldest and imparting training related to the mango cultivation practices among the mango growers. The major objective of the present study was to-find out the technical knowledge, skill and adoption level of mango cultivation practices. A total number of 40, out of 96 trainees respondents related to mango production were selected through the random sampling techniques. The selected trainee’s respondents were personally interviewed through the pre-tested interview schedule. The results of the study showed that, awareness of mango varieties was high but the knowledge level about insect-pest control was very less among the trainees respondents. In the skill and adoption level, the trainee respondents, adopted highly the fertilizer utilization pattern with the recommended dose during plantation in comparison to other activities. The present study indicated that significant level between socio-economic status and various mango cultivation practices was different by one per cent and five per cent level of significance.
