सेमिओकेमिकल्स - अनाज संग्रहीत कीट प्रबंधन के लिए एक वैकल्पिक विधि The rising concern on pesticide residue free products, reduction in cost of chemical control and resistance development had led to the search for an alternate eco friendly and economically feasible tactic. With advancement in the studies on various approaches in IPM of storage pests it is considered that semiochemicals particularly pheromones, have good potential for the suppression of stored-product insects by modifying or manipulating their behaviour. सेमिओकेमिकल्स - अनाज भंडारण कीट प्रबंधन के लिए एक वैकल्पिक विधि One third of world’s food grain is being lost during storage every year due to various biotic and abiotic factors. The biotic factors include attack of different pests like insects, fungi, bacteria, rodent’s etc. Abiotic factors like high grain temperature and moisture, along with dockage, broken kernels and lack of regular monitoring provide conditions that accelerate mold and insect development. Among which more damage is due to insect pest attack. In India, post-harvest losses caused by the unscientific storage, insects, rodents, micro-organisms etc., account for about 10 per cent of total food grains. Stored product pests are obligatory pests that can infest and damage a wide variety of food materials. Different stored grain pests have their own different ways of feeding and damaging the grains ultimately leading to huge...

कारगिल, लद्दाख क्षेत्र में कोडलि‍गं मोथ के प्रबंधन के लिए एक संभावित उपकरण - सामूहिक फंदा (मास ट्रैप)  Mass trapping is just as the name suggests, placement of a large number of traps in an area, which usually have a sticky cardboard bottom baited with pheromone lures. The lure mimics the scent of a female moth attracting male moths to the trap with the result preventing or delaying mating. Mass trapping requires a high density of traps in order to remove enough males to reduce insect damage. Mass trapping has been attempted for a variety of agricultural, orchard and forest pests on scales ranging from a few to thousands of hectares . The majority of mass trapping programs have been used for pest management rather than eradication program. Mass trapping has been tested both as a stand-alone control method and in combination with insecticides and other treatments. It can help to reduce codling moth populations but won’t  eliminate the damage. This method works best where trees are isolated from other trees harboring codling moth (Apple, Pear, English Walnut). The key objective of mass trapping in pest management or eradication is to capture enough insects in the treated area before they reproduce or damage crops, which requires the following:- Deployed traps release pheromone/attractant that is perceived by...
