INSECTICIDAL VALUE 
The publications abstracted in this digest record the results of 
tests with DDT preparations on 325 identified speoies of insects and 
other arthropods belonging to 18 orders and sub-orders, 99 families, 
and 220 genera. There is no relationship apparent between the classi- 
fication of the insect and its susceptibility to DDT. Sometimes differ- 
ent speoies in the same genus, e.g. the pepper and boll weevils, react 
differently to the same formulation of DDT* As a matter of convenience 
in handling a large mass of data the generio names of the insects are 
arranged alphabetically under the family names whioh in turn are 
arranged alphabetically under the order or suborder. These larger 
groups are arranged aocording to increasing complexity of structure— 
Orthoptera, Coleoptera, Lepidoptera, Hymenoptera, etc*
