Insecticide Resistance
Insecticide resistance is an increasing problem faced by those who need insecticides to efficiently control medical, veterinary and agricultural insect pests. In many insects, the problem extends to all major groups of insecticides. Since the first case of DDT resistance in 1947, the incidence of resistance has increased annually at an alarming rate. It has been estimated that there are at leas...
متن کاملInsecticide Resistance and Resistance Management
J. Econ. Entomol. 88(5): 1113-1119 (1995) ABSTRACT Field and laboratory tests were done to determine effects of application technology, plant age, Bacillus thuringiensis (Berliner) subspecies, and rate of application on mortality of 2 populations of diamondback moth, Plutella xylostella (L.). One population was susceptible (Geneva 88) and the other (Loxa b) was resistant to Bacillus tlwringiens...
متن کاملFitness costs of insecticide resistance in natural breeding sites of the mosquito Culex pipiens.
Genetic changes conferring adaptation to a new environment may induce a fitness cost in the previous environment. Although this prediction has been verified in laboratory conditions, few studies have tried to document this cost directly in natural populations. Here, we evaluated the pleiotropic effects of insecticide resistance on putative fitness components of the mosquito Culex pipiens. Exper...
متن کاملSymbiont-mediated insecticide resistance.
Development of insecticide resistance has been a serious concern worldwide, whose mechanisms have been attributed to evolutionary changes in pest insect genomes such as alteration of drug target sites, up-regulation of degrading enzymes, and enhancement of drug excretion. Here, we report a previously unknown mechanism of insecticide resistance: Infection with an insecticide-degrading bacterial ...
متن کامل45 - 52 Insecticide resistance
Laboratory-bred females of Culex quinquefasciatus, Aedes aegypti and Aedes albopictus from the insectarium, Unit of Medical Entomology, Institute for Medical Research were used in the experiment. The late third stage of the F0 larvae which survived the high selection pressure of malathion, permethrin and temephos were reared and colonies were established from adults that emerged. Cx. quinquefas...
