The feasibility of using genetically modified plants for insect control has been clearly demonstrated by expressing the Bacillus thuringensis (Bt) toxins or the protease inhibitor genes. These compounds have been proved to control several insect pests in different crops.

Pest Control: Biopesticides' Potential
Science, 2013The special section on Smarter Pest Control (16 August, p. 728) highlighted the threats that chemical pesticides pose to human health and the environment, and some of the smart alternatives, including genetically modifi ed (GM) crops. However, an important and emerging technology against insect pests was overlooked: biological pesticides.

Consider a population of individuals in some habitat. When the existence of this population in the habitat is damaging in some sense, one is faced with the problem of controlling the growth of the population within that habitat. Such control action involves cost due to labour, materials, risk, etc. and it is therefore necessary to weigh the damage done

Pest Control: Embrace Marketing [PDF]
Science, 2013 In his News Story “Vietnam turns back a ‘tsunami of pesticides’” (special section on Smarter Pest Control, 16 August, p. [737][1]), D. Normile attributes the increase in pesticide use in Asia to “very powerful marketing forces.” Yet, the campaigns that convinced Vietnamese rice farmers to use less pesticide also used marketing principles and tools ...

Insecticide and Acaricide Tests, 1989
Abstract Experimental plots (12 by 12 m) were established in a field of ‘Olds-88’ alfalfa at the University of Wisconsin Arlington Research Station in Columbia County. Each treatment was replicated 4 times and arranged in a randomized complete block design.

Plants are attacked by a plethora of pathogens or pests. Pest attack in turn induces or enhances the synthesis of a many chemical ‘weapons’ produced by plant defenses. These chemicals are classified broadly into nitrogen compounds, terpenoids and phenolics. They have a broad range of antifungal, antimicrobial and pesticidal activities.

About 3 billion tons of pesticides are applied each year in the world. However, despite this large amount of pesticide applied worldwide, pests, insects, weeds and plant pathogens destroy about 40° of all crops.
