INSECTICIDES FROM PLANTS
A Review oJ the Lit:erat:ure, J 941-1953
By Martin Jacobson, Entomology Research Division, Agricultural
Research SerVice
In 1945 the former BUreau of Entomology and Plant Qua.rantine
issued as E-661, "Plants of Possible Insecticidal Value, a Review
of the Literature up to 1941," by N. E. McIndoo. Since that time
much more information has been obtained regarding these plants.
and many others have been tested Dr used as insecticides, repellents,
or attractants. This review has thereiore been extended to
include the literature frottl 1941 through 1953, as well as a few
references that were omitted from the previous publication. Because
of the desirability of making the compilation as near COmplete
as possible for a given period, the review does not extend
beyond 1953; the lag is accounted for by the fact that references
to much of the foreign literature are based on summaries appearing
in abstracting journals, and these summaries sometimes appear
several years after completion of the original work.
The plants are grouped by families, a total of 3,111 species being
represented. No attempt has been made to include the large
volume of material on the plant insecticides pyrethrum, rotenone,
and nicotine, which are a.lready well known and widely used.
We are indebted to S. F. Blake and F. J. Hermann, of the Crops
Research Division. for supplying the botanical authorities and
checking the order, fa.mily, genus, and species names of the
plants. Authority names could not be located for those few plants
lacking such names in this review.
