उत्तर पूर्वी हिमालय क्ष्‍ोत्रो में दालों के कीट पतंग व उनका प्रबंधन Insect pests inflict enormous losses to the agricultural production system. Anecdotal evidences also indicates rise in losses, despite increasing use of chemical pesticides.  At the same time, there is rising public concern about the potential adverse effect of chemical pesticides on human health, environment and biodiversity. The intensity of these negative externalities though cannot be eliminated altogether, but that could be minimized through IPM techniques. The North Eastern Hill (NEH) region of India is characterized by inaccessibility, fragility and marginality with rich biodiversity, ethnicity and societal set up.  It has wide range of agro-climatic conditions with high rainfall and low productivity....

शुष्क फलों के प्रचलित कीट-पतंग और उनके प्रबंधन के विकल्प Remarkable increase in fruit crops cultivation under hot arid region of western India lead to drastic changes in the pest population dynamics. The fruits such as ber (Ziziphus mauritiana), date palm (Phoenix dactylifera) and bael (Aegle marmelos) are an important fruit crops grown in this area. The productivity is concern, it is low because of harsh environment (high temperature, low precipitation, high PET, high wind velocity), poor soil fertility and salinity. Beside these, the biotic pressure like pest and diseases also play a critical role, which cause significant loss and adds cost of production. Hence, in this article we discussed the...

कीट प्रबंधन में जैव कीटनाशकों की भूमिका More and more quantities of chemicals are used for agriculture  intensification to feed on ever growing population. In fact the pest induced loss is on the rise despite increasing usage of pesticide, fortunately, realizing of the negative effect of these chemicals on natural and natural resources like pollution.  Pesticide residue, pesticide resistance etc, have forced many to shift focus on to more reliable,  Sustainable and environment friendly agents of pest control, the bio pesticides.  In view of this demand and Governments efforts to mitigate climate change, biopesticides are going to play an important role in future pest management programme. Biopesticide :- Bio pesticides include " naturally...
