Southern house mosquito

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. 

Larvae 3 days old were used in testing. Tests were conducted in the same manner as with the southern house mosquito. 

An aqueous solution containing 1 part in 200,000,000 of parathion gave 50% kill to southern house mosquito larvae (Culex quinquefasdaius Say). Parathion solutions did not lose any toxicity on standing for a month at room temperature (Figure 1). At the end of 2 months, however, the solutions lost their toxicity to mosquito larvae. 

Scheme 41 summarizes Couladouros s synthesis of the oviposition attractant pheromone of the Southern house mosquito (Culexpipiensfatigans)y (5R,6S)-6-acetoxy-5-hexadecanolide (28) [66]. The key-steps are (i) -selective Schlosser olefination (A B), asymmetric dihydroxylation (B C), and lactonization of carbonate C to the desired 6-lactone with inversion at C-5. 

This egg signal may find some practical application. Southern house mosquitoes are common pests and can bear dangerous illnesses. In the southern United States, they carry two well-known parasitic diseases St. Louis encephalitis, a human viral disease, as well as dog heart worm, a disease caused by a nematode (round-... 

Southern house mosquito [Culex quinquefasciatus) is widely distributed in tropical and subtropical areas worldwide and the most important target for mosquito coils. Mosquito coils containing 0.005% metofluthrin exhibited an efficacy exceeding that of coils containing 0.2% d-allethrin against this species (laboratory strain), and the relative efficacy is estimated to exceed 40 times that of d-allethrin (Figure 7). 

The Southern house mosquito Culex quinquefasciatus) is highly sensitive to it, and uses it to guide its egg-laying.
