The development by insects of resistance to insecticides.
Pesticides designed to control insects that are harmful to man. The insects may be directly harmful, as those acting as disease vectors, or indirectly harmful, as destroyers of crops, food products, or textile fabrics.
A genus of mosquitoes (CULICIDAE) that are known vectors of MALARIA.
The branch of medicine concerned with diseases, mainly of parasitic origin, common in tropical and subtropical regions.
The active insecticidal constituent of CHRYSANTHEMUM CINERARIIFOLIUM flowers. Pyrethrin I is the pyretholone ester of chrysanthemummonocarboxylic acid and pyrethrin II is the pyretholone ester of chrysanthemumdicarboxylic acid monomethyl ester.
The reduction or regulation of the population of mosquitoes through chemical, biological, or other means.
A species of mosquito in the genus Anopheles and the principle vector of MALARIA in Africa.
A genus of mosquitoes (CULICIDAE) commonly found in tropical regions. Species of this genus are vectors for ST. LOUIS ENCEPHALITIS as well as many other diseases of man and domestic and wild animals.
Reduction of pharmacologic activity or toxicity of a drug or other foreign substance by a living system, usually by enzymatic action. It includes those metabolic transformations that make the substance more soluble for faster renal excretion.
Poisoning due to exposure to ORGANOPHOSPHORUS COMPOUNDS, such as ORGANOPHOSPHATES; ORGANOTHIOPHOSPHATES; and ORGANOTHIOPHOSPHONATES.
A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985). (From Merck Index, 11th ed)
A pyrethroid insecticide commonly used in the treatment of LICE INFESTATIONS and SCABIES.
The reduction or regulation of the population of noxious, destructive, or dangerous plants, insects, or other animals. This includes control of plants that serve as habitats or food sources for animal pests.
The reduction or regulation of the population of noxious, destructive, or dangerous insects through chemical, biological, or other means.
Use of naturally-occuring or genetically-engineered organisms to reduce or eliminate populations of pests.
A genus of mosquitoes (CULICIDAE) frequently found in tropical and subtropical regions. YELLOW FEVER and DENGUE are two of the diseases that can be transmitted by species of this genus.
Insects of the suborder Heterocera of the order LEPIDOPTERA.
A large order of insects comprising the butterflies and moths.
A potent mast cell degranulator. It is involved in histamine release.
Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses.
Educational institutions for individuals specializing in the field of veterinary medicine.
A discipline or occupation concerned with the study of INSECTS, including the biology and the control of insects.
A family (Aphididae) of small insects, in the suborder Sternorrhyncha, that suck the juices of plants. Important genera include Schizaphis and Myzus. The latter is known to carry more than 100 virus diseases between plants.
