Bibliography on insect pest resistance in plants, with a supplement on resistance
to nematodes (Cambridge, Eng.: Imp. Bur. Plant Breeding and Genet.,

by host plants attacked.
Agricultural insecticides, [I], II (Soap and Sanit. Chem., 19 (1943), No. 12,
pp. 121, 123, 125, 143, illus. 2; 20 (1944), No. 1, pp. 119, 121, 123).-A review of
recent reports of various State agricultural experiment stations, indicating that
much work is now being concentrated on the search for effective substitutes for
insecticides in short supply and on the development of application technics that will
make more economical use of such supplies as are available.

illus. 2).-Includes 30 literature references.
Further refinement of a technique for testing contact insecticides, W. S.
McLEOD (Canad. Jour. Res., 22 (1944), No. 4, Sect. D, pp. 87-104, illus. 3).When
Drosophila melanogaster was sprayed with nicotine sulfate solution by both
intermittent and continuous methods, no clearly demonstrated superiority of one
technic over the other was observed. An analysis of variance performed on observed
mortalities expressed as angles of equal information showed that increasing age
of flies, increasing number of flies per cage, longer delays between filling of cages
and spraying, and increased proportion of $ $ in the samples raised the observed
mortalities significantly. Data on fly ages and numbers per cage were also put
through the probit analysis of Bliss, which indicated that those 5 days old are most
susceptible and that fly numbers affected equally the mortalities due to all concentrations.
The type of cloth used to cover the cages should be standardized.
Relative effects of several base oils used in livestock sprays on the skin of
cattle, F. W. ATKESON, A. R. BORGMANN, R. C. SMITH, and A. O. SHAW. (Kans.
