Aedes aegypti

Recently a new constituent of pyrethrum extract was described by Godin et al. (9) jasmolin II, the cir-pent-2-enylrethronyl ester of pyrethric acid. Jasmolin II differs from pyrethrin II in that the terminal double bond of the alcoholic side chain is saturated. This constituent forms about 3% of the total pyrethrins. Jasmolin II is less toxic to the insects tested than a similar concentration of pyrethrins. The pyrethrum extract was 16 to 17 times as toxic as jasmolin II to Aedes aegypti and Fhaedon cochlearia adults, less than 17 times...

As mosquito larvae are relatively easy to kill with insecticides, any toxic spray residue is likely to be detected. Two species of mosquito larvae were used, the yellow fever mosquito (Aedes aegypti L.) and the southern house mosquito (Culex quinquefasdatus Say). Tests with the southern house mosquito were made essentially according to the method of Campbell, Sullivan, and Smith (I), except for the kind of food supplied and size of containers used. 

In addition to the tests made on peaches and apricots, samples of prunes from trees that had been sprayed with parathion, DDT, DDD, basic lead arsenate, and toxaphene at the rate of from 1 to 2 pounds of these insecticides per 100 gallons of water were tested on larvae of Aedes aegypti. The trees had been sprayed on April 20 and June 16, 1948. The fruit was harvested on or about September 10. Prunes from trees that had been treated with 1 quart of tetraethyl pyrophosphate and 12 pounds of sulfur dust per acre on June 15, and harvested about July 6, were tested on larvae of the above named species. None of the prune samples tested in this study exhibited any significant toxicity to mosquito larvae as compared with the unsprayed check.

The lethal efficacy of Metofluthrin against four medically important mosquito species (C. pipiens pallens, Culex quinquefasciatus, Aedes aegypti, and A. albopictus) is summarized in Fig. 2. The efficacy of Metofluthrin was found to be very high against all these 4 species and it was between 19 and 49 times higher than that of d allethrin.

The jet plane has made it easy to travel to and from previously inaccessible parts of the world, for business or vacation. Infectious diseases or agents that transmit these diseases can, therefore, be rapidly transferred to countries in which the population has never encountered the diseases, so that the infection rapidly spreads throughout the population. Such transport of pathogens is reminiscent of the transmission of diseases that were previously unknown in North America but were transported from Africa in the slave ships. For example, the mosquito Aedes aegypti, which transmits the virus that causes yellow fever, was probably transported in water barrels on these ships. 

The Aedes aegypti (Diptera Culicidae) mosquito is the primary vector in transmitting dengue and yellow fever. Insecticide use has been the primary method of control of this and other mosquitoe species. Piperine [(T,. S )- -piperoyl-piperidine], is the major constituent in Piper nigrum...
