Larvicidal control of peridomestic mosquitoes

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1955
Abstract 1. (1) The problem of mosquito breeding in peridomestic water containers is discussed, with special reference to conditions in Eastern Nigeria. An attempt at control by sealing water pots using local materials which was successful for a time, but later frustrated by local social custom, is described.

Ovicide, Larvicide Trials, 1988

Insecticide and Acaricide Tests, 1989
Abstract A small-plot field study was conducted in a commercial cotton field near Austwell, Tex., to measure the effects of 6 treatments on survival of tobacco budworm eggs and freshly hatched larvae of tobacco budworm. The eggs were obtained from pyrethroid-susceptible and pyrethroid-resistant strains of tobacco budworm (ICI laboratory ...

Larvicidal Constituents ofMelantheria albinervia

Planta Medica, 1995
Bioactivity-guided fractionation has led to the isolation of two larvicidal diterpenes, active against the yellow fever-transmitting mosquito Aedes aegypti, from a dichloromethane root extract of Melantheria albinervia (Asteraceae), a plant from Zimbabwe. These diterpenes were identified as ent-kaur-16-en-19-oic acid and 9(11),16-kauradien-19-oic acid.

Larvicidal Diterpenes from Pterodon polygalaeflorus

Vector-Borne and Zoonotic Diseases, 2006
Ethanolic extract from seeds of Pterodon polygalaeflorus (Benth) has been shown to possess significant larvicidal activity against the mosquito Aedes aegypti. Bioassay-guided fractionation of the extract led to the isolation and characterization of the know diterpenoid furans 6alpha-hydroxyvouacapan-7beta,17beta-lactone (1), 6alpha,7beta ...

Tests (1967) with Black Fly Larvicides

Journal of Economic Entomology, 1968
Four pesticides were tested near Ithaca, New York, against larvae of the black fly, Simulium pictipes Hagen. The 4 were, Abate® (O,O -dimethyl phosphorothioate O,O -diester with 4,4'thiodiphenol), Dursban® (O,O -diethyl O- (3,5,6-trichloro-2-pyridyl) phosphorothioate), ronnel.

Bacteriological larvicides of dipteran disease vectors

Trends in Parasitology, 2001
The apparent success in vector control observed between 1950 and 1970 was followed by worldwide resistance to organosynthetic insecticides wherever they were used intensively. Insect resistance to one or more categories of insecticides has limited the effectiveness of these compounds, and their non-selective mode of action adversely affects non-target ...

Effect of Larvicides on Simulium Eggs

Nature, 1969
Simulium, the biting pest and vector of human onchocerciasis, is best controlled by the regular use of larvicides—DDT in particular—in the streams and rivers in which the immature stages develop1. The speed of reinfestation after the application of larvicide suggests that Simulium eggs are not affected by the doses usually applied2.
