The complex interaction of environmental stress, poor natural regeneration and insect pests have lead to forest decline in Himalayan sub-region. Amongst the insects, stem and wood boring beetles are capable of causing significant oak mortality. The paper reports the outcome of surveys on wood boring beetles carried out in moist temperate oak forests, mainly with Ban oak, Quercus leucotrichophora Camus, Moru oak, Q. dilatata Lindl and Q. semicarpifolia Smith in six sites in the Garhwal region of Uttarakhand, India.
The negative effects of climate change are already evident for many of the 25 million coffee farmers across the tropics and the 90 billion dollar (US) coffee industry. The coffee berry borer (Hypothenemus hampei), the most important pest of coffee worldwide, has already benefited from the temperature rise in East Africa: increased damage to coffee crops and expansion in its distribution range have been reported. In order to anticipate threats and prioritize management actions for H. hampei we present here, maps on future distributions of H.
Forest Research Institute (FRI), Dehradun, is for the past one year, trying to find a way to control the gall disease that has affected almost 50 per cent of the eucalyptus trees being grown in the
Hard rot disease, a fungal infection of plants characterised by lesions with hard surfaces and rotten tissue, is affecting an increasing number of pasur (Xyicarpus mekongensis pirre) trees in diffe
For centuries, the whitebark pine, Pinus albicaulis, has grown on hundreds of thousands of acres across the West. It is a keystone species of an entire ecosystem — one now seriously at risk.
Nestle on Wednesday ramped up its distribution of disease-resistant cocoa trees to farmers in Ivory Coast, part of a plan to boost productivity per hectare and improve the notoriously poor quality of the top grower's cocoa beans.
The world's biggest food maker, which has distributed some 140,000 saplings since 2009, said it will hand out 600,000 saplings by the end of the month and a further on
During the late 1950s and early 1960s food deficits India has been requiring importation of 3 to 4 million tons of grain per year. However because of bad monsoons in 1965 and 1966, imports exploded unpwardly to 10 million tons, and India was in dire straits. It was during this period that, after three years of testing on experiment stations, the so-called high yielding Mexican wheat varieties, which had proven very interesting under experimental conditions, where considered as a possible way to break the worsening food deficit.
