Comparative study of the ultrastructure and metabolism of the fat body of diapausing and nondiapausing larvae of the southwestern corn borer, Diatraea grandiosella Dyar (lepidoptera : pyralidae)
(University of Missouri--Columbia, 1976)"The southwestern corn borer, Diatraea grandiosella (Dyar), is a pyralid moth which enters diapause as a mature larva and is bivoltine under Missouri conditions. The bionomics of the species have been reviewed in several ... -
Environmental regulation of the larval diapause of the southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera : pyralidae)
(University of Missouri--Columbia, 1973)Diapause is a state of arrested growth or reproduction which is commonly found in insects (Lees, 1955). It may occur at any stage in the life cycle of an insect and is usually an important adaptation in the development of ... -
Nutrition and feeding behavior of the southwestern corn borer Diatraea grandiosella Dyar (Lepidoptera : pyralidae)
(University of Missouri--Columbia, 1972)The aim of the study was: 1) to determine the nutritional requirements of the southwestern com borer for proteins, carbohydrates, lipids, minerals and vitamins, 2) to measure the effects of carbohydrates and lipids on the ... -
Photoperiodic time measurement and seasonal adaptation of the southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera : Pyralidae)
(University of Missouri--Columbia, 1978)"Photoperiodism is an adaptation which enables organisms to maintain maximum reproductive and survival efficiency under periodically changing environmental conditions. Since daylength is astronomically stable, it gives ...
