Excerpt from Experiments and Suggestions for the Control of the Codling Moth in the Grand Valley of Colorado Arsenate Of lime, both homemade and commercial, as used in plats VII and VIII, gave comparatively poor results. The unsprayed or check trees, plat X, were very Wormy, giving but 13. 51 per cent Of fruit free from larvae. The sprayed fruit was well protected against the calyx entrance worms except in plat VIII. With this exception, the percentage Of wormy apples infested. At the calyx in the sprayed plats varied from to The unsprayed plat produced per cent Of wormy fruit infested at the calyx.

When Patrick A. Buxton was appointed by the London School of Hygiene and Tropical Medicine in 1926 to head their Department of Medical Entomology, he had formed the opinion that the control of the insect-borne diseases of the tropics was being impeded by lack of knowledge about the physiology of insects. He persuaded the Board of Management to agree to the selection of a lecturer who would endeavour to advance the subject of insect physiology; and at the suggestion of Sir Gowland Hopkins, under whom I had worked at Cambridge, and with the support of Sir Walter Morley Fletcher, Secretary of the Medical Research Council and a member of the Board of Management, I was appointed to this post - with opportunity for extensive travel to study medical entomology in the tropics and with abundant time for research. Some seventeen years later, during the war years, W. W. C. Topley, as Secretary of the Agricultural Research Council, was faced with the urgent need for improved methods of control of insect pests in agriculture and horticulture by insecticidal or other means. As a support for this objective he recommended the establishment of a Unit of Insect Physiology to carry out basic research which would be of potential value to agriculture; and I was invited to act as director. So once again I was able to undertake world-wide travel - to learn the elements of agricultural entomology.

In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.
