Nuclear Polyhedrosis Virus (NPV), A Potential Biopesticide: A Review
The indiscriminate use of pesticides for the last 40 years has almost eliminated natural enemies from many crop eco-systems. This scenario has led many countries to consider the potential of biological control as a component of pest management. At present, the world market for microbial pesticides is in excess of US $ 125 million per annum which is still less than 1 percent of the total global ...
متن کاملA 'metaphising' dung beetle.
You may have seen the film Microcosmos, produced in 1996 by the French biologists Claude Nuridsany and Marie Perrenou. It does not star humans, but much smaller creatures, mostly insects. The filmmakers’ magnifying camera transposes the viewer into the world of these organisms. For me, Microcosmos is not an ordinary naturalist documentary; it is an exercise in metaphysics. One sequence in the f...
متن کاملBiopesticide production from Bacillus thuringiensis: an environmentally friendly alternative.
Since its discovery as a microbial insecticide, Bacillus thuringiensis has been widely used to control insect pests important in agriculture, forestry, and medicine. The wide variety of formulations based on spore-crystal complexes intended for ingestion by target insects, are the result of many years of research. The development of a great variety of matrices for support of the spore-crystal c...
متن کاملApplication of Membrane Separation Technology in Downstream Processing of Bacillus thuringiensis Biopesticide: A Review
Bacillus thuringiensis (Bt) has been extensively used in biopesticidal formulations due to its safe environmental and human health records. The widespread use of Bt is often challenged by production as well as formulation costs which are in direct contact with downstream processing, i.e. the separation/purification step. Downstream separation/purification efficacy governs the marketabi...
متن کاملRNA interference: a promising biopesticide strategy against the African Sweetpotato Weevil Cylas brunneus
The African sweetpotato weevil Cylas brunneus is one of the most devastating pests affecting the production of sweetpotatoes, an important staple food in Sub-Saharan Africa. Current available control methods against this coleopteran pest are limited. In this study, we analyzed the potential of RNA interference as a novel crop protection strategy against this insect pest. First, the C. brunneus ...
