Larvicidal activity of para-Benzoquinones

Parasitology Research, 2010
Plant products may be alternative sources of mosquito larval control agents, since they constitute a rich source of bioactive compounds that are biodegradable into nontoxic products. It has been reported that quinones and derivatives present toxic activity against mosquito larvae Aedes aegypti.

Thiosemicarbazones as Aedes aegypti larvicidal

European Journal of Medicinal Chemistry, 2015
A set of aryl- and phenoxymethyl-(thio)semicarbazones were synthetized, characterized and biologically evaluated against the larvae of Aedes aegypti (A. aegypti), the vector responsible for diseases like Dengue and Yellow Fever. (Q)SAR studies were useful for predicting the activities of the compounds not included to create the QSAR model as well as to

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.

Optimal Distribution of Larvicide in Running Waters

SIAM Journal on Optimization, 1992
The authors consider the following control problem: At what locations should larvicide be injected into a river such that a (given) minimum dose is maintained throughout and such that the total amount of larvicide sprayed is minimized? It is the object of the paper to derive a mathematical model for this problem (a diffusion-transport equation with ...

On the larvicidal properties of charophytes

Hydrobiologia, 1963
1. The larvicidal properties of three species of charophytes are investigated. 2. The results obtained are statistically analysed. 3. It has been observed that the larvae of female mosquitoes are more susceptible to death than those of males in cultures of charophytes.

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.
