Biotechnological Approaches for the Control of Insect Pests in Crop Plants
Each year billions of dollars are spent worldwide on insect control in agriculture [1]. Despite this expenditure, up to 40% of a crop can be lost to insect damage, particularly in developing countries [2]. Some of the most damaging insect species belong to the Lepidoptera, the second largest insect order comprised of moths and butterflies. The larval stage of moths cause major damage to an arra...
متن کاملInvestigating Engineered Ribonucleoprotein Particles to Improve Oral RNAi Delivery in Crop Insect Pests
Genetically modified (GM) crops producing double-stranded RNAs (dsRNAs) are being investigated largely as an RNA interference (RNAi)-based resistance strategy against crop insect pests. However, limitations of this strategy include the sensitivity of dsRNA to insect gut nucleases and its poor insect cell membrane penetration. Working with the insect pest cotton boll weevil (Anthonomus grandis),...
متن کاملInsect defence: its impact on microbial control of insect pests
Insects are the earliest and most diverse taxon of animals accounting for more species than all other animals put together because of their high reproductive potential and varied niche. Though cellular reactions like phagocytosis, nodulation and encapsulation and humoral reaction through secretion of antibacterial proteins are known for fungus and bacterial invaders, little is known about insec...
متن کاملAlternatives to Chemical Control of Insect Pests
In 2011, practitioners and advocates of Integrated Pest Management (IPM) find themselves addressing agricultural, societal, and political pressures worldwide resulting from human population growth. This growth brings simultaneous burdens of sustaining a steady food supply; these include preventing losses from pests, dealing with increased human global travel, which in turn intensifies opportuni...
متن کاملManaging Insect Pests of Rice in Africa
(eds M.C.S. Wopereis et al.) 229 In the search for sustainable management options to increase food security, an overall challenge is to increase yields and decrease losses during production and harvest without harming the environment and resource base for future generations of farmers and consumers. As such, integrated pest management (IPM) plays a key role in the context of sustainable agricul...
