Promising results were obtained with sprays containing Pyrethrum in experiments to control Mineola Scitulella Hulst, a pest of the prune in southwestern Idaho, A summary of the life history of the insect is given. The materials tested were Pyrethrum extracts used in combination with kerosene emulsion, soap, and dormant type oil; a Pyrethrum-rotenone preparation; nicotine sulphate and nicotine preparations; lime-sulphur and lead arsenate. Best results were obtained with a kerosene solution of Pyrethrum in a kerosene-soap emulsion spray, which gave a kill of 93%. The larvae became greatly activated in the buds sprayed with this material, the activity ceasing in about two hours, after which time death occurred.
