Examines proposals for energy production from organic substances such as wastes, trees, and grain and foilage crops. Describes techniques of energy extraction from these substances. (CP)

Discusses the need for concurrent attention to methods of pest management when ecological changes consequent upon the introduction of new grains occur in large areas of the tropics. (AL)

Describes gene infusion, the continual replacement of genes for insecticide susceptibility into insect populations, to control the level of resistant genes in pest populations. (AL)

Animal foods are not only rich in nutrition but also are a source of many by-products which otherwise would not be used for human food. (PS)

In the light of new knowledge about insecticides, future research should be conducted by plant and insect physiologists together. Plant physiologists should explain what characteristics in plants attract insects and insect physiologists should study adaptive patterns of insects and combine their knowledge to control insects.
