Management of Pest and Beneficial Insects Cotton Cropping Systems in Australia | Natural Pest Control | Scoop.it

IndianJournals.com - A review is published on Exploitation of semiochemicals for the management of pest and beneficial insects with special emphasis on cotton cropping systems in Australia.


The paper examines semiochemicals, substances or mixtures of substances produced by one species that influence the behaviour of receptor organisms, from the perspective of their potential in a sustainable pest management context. Particular reference is made to Helicoverpa spp. and their natural enemies on cotton and to those chemical components derived from the inner tissues and organ surfaces of plants. The post-alightment behavioural sequence of insect pests such as Helicoverpa spp. which lay eggs on plants which are not a food source, includes the sensing of small quantities of many types of chemical substances that may include free amino acids, organic acids, sugars, secondary metabolites, vitamins, minerals, growth regulators, etc. Detection of these substances on the leaf or organ surfaces of the plant provides specific information to the female insect on plant health, physiology and nutrition that guides the insect to either accept or reject the plant for oviposition. Three behaviour manipulation methods for pest management have been identified as (1) a behaviour of the pest, (2) a means by which the behaviour is manipulated appropriately, and (3) a method that utilizes the behavioural manipulation method for the protection of the resource from the pest.
