The carbon emission is one of the main causes of global warming which is leading to drastic climate change. There has been compulsion for India to minimize carbon emission by at least 25% and it was the main issue of Copenhagen Climate change meets 2009. Electric bike (ebike) is one solution to reduce the carbon emission in the automotive world. This paper reports about the history, necessity, technical details, advantages&disadvantage along with word wide and national scenario of ebike sector.References

Resistance has been defined as a developed ability in a strain to tolerate doses of toxicants which would prove lethal to the majority of individuals in normal population of the same species (Anonymous,1957), World Health Organization (WHO), Expert Committee on Insecticides, (1957). Insecticides resistance management (IRM) strategies are becoming more important in agricultural production system. Pest resistance to a insecticide can be managed by reducing selection pressure by the insecticide on the pest population.Preventing and managing resistance to insecticides is an important stewardship practice that ensure insect control products will remain effective long term.In other words, the situation when all the pest except the most resistant ones are killed by a given chemical should be avoided.Resistance to insecticides was first documented in 1914 by A. L. Melander in the Journal of Economic Entomology.References

Snails and slugs are part of the class of creatures called gastropods. Gastropod comes from the Greek wordsgastros (stomach) and podos (foot). They are the animals without backbones, having asymmetrical, unsegmented and spirally coiled body. When snails have a well-developed shell, slugs have only a rudimentary shell often enclosed in a visceral hump. Snails and slugs are hermaphrodites but there is reciprocal exchange of spermatozoa as they mature before development of eggs. Self-fertilization is prevented. They have good protection against dehydration; hence they avoid direct sunlight and environments with a low relative humidity. They hide during day time in moist places or under debris and feed mainly at night when the temperature drops and humidity rises. Snails secrete light yellow slime and slugs secrete colourless slime which becomes silvery after drying.References

Insecticide use is an important and integral component of crop production system. Insecticide use increased substantially over the years. Insecticide consumption increased by 2158.6 per cent in 2004 over 1982, but now there is declining trend in their use. Indiscriminate use of insecticides also lead to several diseases in human health. Concentration of insecticide in surface and ground water is also a major factor for environmental pollution. Insecticide like Diazinon shows the maximum concentration in surface and ground water. Therefore, the concentration of Diazinon should not be more than the recommended limits i.e. 0.003 μg/l to protect the fresh water aquatic life and also eliminate the lethal effects of insecticide residues in ground water. The status of the insecticide residue in lake water i.e. the areas that were not involved in vegetable or horticultural farming is highest in chlorpyriphos ethyl (which was above WHO limit) while the residual levels of endosulfan sulphate and endosulfan ether found in agricultural soil were higher than those of alpha and beta endosulfan, which indicates that degradation reactions take place mainly in agricultural soil.Keywords

Banana (Musa sapientum) is an important tropical fruit crop in India. External appearance of is important factor which decides the market value of the product. Many banana growers suffer huge monetary loss due to pre harvest eating of insects especially scaring beetle, mechanical injury, damage of foxes etc. In Khowai district of Tripura, the infestation of insect was found to be very high. To address the problem an experiment was conducted in the instructional farm of KVK, Khowai, Tripura, India during the year 2016-17 and 2017-18. Ten numbers of bunches were random selected from an already existing banana cv. SABRI orchard. The experiment was comprises of two treatment- T1 : bunches are covering with 6 per cent ventilated Polythene covers / sleeves of size 200 cm length x 150 cm width x 175 gauge thickness and T2 : not covered or control. It was observed that the banana fruits matured under covered condition were more visually appealing as they were clean and had minimal bruises, especially more large-grade fruit with uniform fullness of fruit within the bunch compared to those grown uncovered. 11.45 per cent more finger length and 7.35 per cent more individual fruit weight was noticed in cover bunches compared to that uncovered. Bunch covering also had a positive on the TSS content of the fruit. Further, bagging helps in shorten the time from flowering to physiological maturity by 10. Thus bunch covering can be recommended for commercial banana orchards in Tripura to produce high quality fruits.Keywords
