D. Physiological Effects on Plants, 
Vertebrate Animals and Insects 
Mode of Action of Insecticides. Study: metabolism of 
various insecticides in many species of insects, and bio- 
chemistry of the nervous and muscular system in Blattella. 
Ent. and Parasitol. 902C 
Effects of Fumigants, Insecticides, and Herbicides on Soil 
Productivity. Learn Gis) influence of soil properties and various 
soil management practices on effectiveness of fumigants, insecti- 
cides and herbicides; (2) effect of fumigants, insecticides and 
herbicides on chemical, physical, and microbiological properties 
of soil with special reference to soil productivity. 
Soil and Pl. Nutr., Ent. 1532 
Long Range Effects of Insecticides on Insect Populations. 
Learn the long range effects of (1) persistent residual insecti- 
cides; (2) quick-acting non-persistent insecticides applied to; 
reduce an existing heavy population, as a preventive in anticipa- 
tion of a heavy population or,to control a light population (sim- 
lating control of a pest reducing quality of crops) on the popu- 
lation of insects. 
Ent. 315 Coop. Dept. of Army Surgeonts General Office 
Differences in Mode of Action of Insecticides. To (1) 
develop more effective techniques and procedures for learning 
differences in mode of action of insecticides applied jointly, 
(2) learn differences in mode of action of insecticides or of 
chemicals under test for usefulness as insecticides. 
Ent. 320 
Effects of Biocidal Materials on the Physiology of Plants. 
To correlate metabolic shifts with morphological changes in 
plants produced as the result of the application of additives 
such as herbicides, fungicides and insecticides. 
Bot. 728 
Study of the Pharmacologic Activity of Certain Chemical 
Pesticides. Study (1) effect of chlorinated naphthalenes on 
pigs; (2) the possible toxic effects of combinations of certain 
agricultural chemicals on laboratory or other animals. 
Vet. Scie 70-328 
Radioisotopes as a Tool in Mode-Of Action Studies of Modern 
Insecticides Used Against the European Corn Borer and Other 
Agricultural Pests. To (1) determine metabolism of radioactive 
DDT, alone and combined with synergists, in European corn borer, 
in house fly, and other resistant and non-resistant strains of 
insects, and (2) study action, residues, and metabolism of radio- 
active systemic insecticides in European corn borer, corn plants, 
the house fly, and the rat.
