The deffotiation epidemic in ailanthus excelsa roxb in satyanarain research nursery was studies. The insect responsible for epidemic was philosamia cythia drury. This is a polyphagous pest and reported for the first time as deffolator of ailanthus excelsa Egg, larva, pups and adult of the species are described and notes on their biology are given. A fungal pathogen, beauveria basslana(Balsama) Vulliemin has been recorded killing the larvae of P.cynthia in the field. The pathogen appears to be a promising organism for microbial control of Ailanthus deffolator in the field.

Effluents from the sea food processing plants discharged into the water bodies may cause eutrophication. This study has been carried out to assess the impact of effluent discharge on water quality and phytoplankton population in Vembanad-kol wetland adjacent to seafood processing industries. Five stations were selected in the Cherthala-Aroor-Edakochi coastal belt of Vembanad lake, four were near to the seafood processing facilities, and the fifth station was kept as a reference site, which is free from the direct seafood processing effluent discharge. Samples were collected on monthly for a period of one year (October 2011 to September 2012) for physico-chemical and biological analysis. The higher level of salinity, alkalinity, hardness, BOD, COD, nitrate, phosphate, ammonia, silicate and depleted level of dissolved oxygen indicated the pollution status of study stations (S1-S4) compared to reference site (S5). Among the 137 genera of phytoplanktons, Bacillariophyceae was the major class followed by Chlorophyceae and Cyanophyceae. In addition to this, the class Rhodophyceae, Chrysophyceae, Haptophyceae, Eustigmatophyceae and Cryptophyceae were also reported. Percentage composition and biological indices of the phytoplanktons were assessed. The pollution tolerant genera like Navicula, Nitzschia, Scenedesmus, Coscinodiscus, Ankistrodesmus, Chlorella, Oscillatoria, Phormidium, etc. were dominant in the four stations (S1-S4) during the study period. This baseline information on the water quality status of Vembanad lake will be useful for future ecological assessment and monitoring to conserve this Ramsar site.Keywords

The community polytechnic programme is a national programme sponsored by the Ministry of Human Resources Development of Government of India to ensure a fair share of benefits of technical education and scientific research for the rural society. Based on the infrastructure, intellectual manpower, experience and capacity of the polytechnics, such institutions were entrusted with community polytechnic programme for their active involvement in the process of rural development. These institutions are expected to act as focal points for technology transfer and promotion of local innovativeness in rural areas. In the State of Jharkhand, appropriate technology may be transferred to the rural people for the sustainable growth of that area. Despite its achievement, the rural masses are not being benefited as has been expected. In order to identify the gap, this research study has been undertaken. An attempt has been made to evaluate the role of polytechnics of Jharkhand (India) in community development. The study reveals that various training programmes have benefited a large number of respondents. It is only after proper need assessment, the programmes can be successfully organised in a meaningful way. Technology transfer and technical-support services are the most urgent components to be diffused in rural areas of Jharkhand. Technical-support services, technology transfer, and need assessment are the prime areas of concern of the community polytechnic programme. By making the local villagers more aware of S&T inputs, the impact level can be further improved.Full Text

Impatiens johnii has high conservation concern due to its rarity and geographical narrow range. This species is a stenotopic endemic in the Munnar landscape and rediscovered after 67 years. This plant was found as part of epilithic along the streams and high canopy areas in high humidity locations at an elevation of 1600–1800 m amsl. I. johnii is distributed in less than 5 km2 area near Eravikulam National Park and therefore this area needs to be protected for the conservation of I. johnii.Keywords
