No. h the senior writers experiments for destruction of Eleodes stUuraliswere carried on along somewhat similar lines, though in a supplementary-way without duplication of experimental work and with special referenceto the habits of the species under consideration. Emphasis was placed onexperiments for the protection of the planted seed, the destruction of thelarva, and the destruction of the pupa and beetle. As the protection of the seed was deemed more especially desirable,much attention was given to this phase of inquiry. Wheat seed wastreated with a great variety of preparations and then subjected to attackby the larva in the hope of finding some effective repellent or poison,but in every case these proved ineffective, for they not only failed to killthe larva, but, what was worse, they often retarded or entirely
