Mosquitocide

Six types of sprayers were tried. […] Mixed catches of mosquitoes were used, the majority being Armigeres obturans, a hardy culecine^([sic]) mosquito. Measured quantities of mosquitocide of known potency were blown off from the various sprayers and the room kept closed for half an hour.

In order to reduce the mosquito population in the summer of 1949, a portion of this area which showed infestation with larvae was sprayed by airplane within the last 30 days. If further tests show the necessity for more extensive air spraying with mosquitocide, additional treatment will be applied.

The broad field of action of aqueous suspensions is indicated by the fact that 12,500 of the liters of mosquitocide with DDT as a base used in Venezuela in 1951 to spray 500,000 houses in the malarial area, 84% were in aqueous suspensions and only 16% in solutions and emulsions.

The following are some examples of the benefits obtained from mangroves. They are a source of wood products – timber, poles and posts, firewood, charcoal; non-wood products such as fodder, honey, wax, tannin, dye and materials for thatching; traditional tea prepared from mangrove leaves serve^([sic]) as a cholesterol feed for prawn, as potential sources of mosquitocide and as a source of anti-viral drug formulation.
