Sample text

During the initiation of this study, it was observed that peroxides increase rapidly during the earlier periods of storage of an isoparaffinie oil i n bright light. However, the peroxide curve often breaks and lower peroxide numbers are obtained before 100% plant mortality is achieved. Although the mechanism was not determined, i t was assumed that at some stage of the oxidation process peroxides were decomposed and acids were formed. In view of the general relationship apparent between acid number and phytotoxicity, it seemed desirable to establish some measure of the rate of acid number increase when an isoparaffinie fraction is stored under different conditions of light intensity.

Petroleum oils in mosquito control are discussed from the pioneering experiments to their present-day status. Used alone or as carrying agents for other materials, such as DDT, petroleum oils have proved almost indispensable as larvicides and adulticides in the control of mosquitoes. Outdoor applications, from the ground and from the air, are described as well as indoor space and residual sprays. Standard specifications are urged for a petroleum oil that may be used as a mosquito larvicide. O i l s have been used for centuries to control certain insects, but the first known record of their use for controlling mosquitoes is found i n Dunlap's American Daily Advertiser i n 1793 (8).

Naphthenic composition of the oils. The LDu for fraction 7 (46-M20), 64 micrograms per sq. cm. (Table I), is about one half, or a little less than half, the average deposit of conventional spray oils used for commercial control of California red scale in the field in California. The results obtained in the laboratory studies indicate that proper selection of spray oils may make it possible to obtain the same degree of control with less oil deposit. Until further information is obtained on the response of citrus trees to differences in the composition of petroleum oil, estimation of the practical value of the differences indicated between the two series of petroleum fractions on the basis of viscosity, in the control of citrus red mite, is limited.
