I have prepared this report primarily to answer queries entomologists about electronic techniques I have used in my ecological studies of the corn earworm, Heliothis zea (Boddie). In these studies, conducted for the most part at the Southern Grain Insects Research Laboratory at Tifton, Ga., during 1962- 63, I utilized certain original circuit with an asterisk standard circuits, which designs can be found in in the References Cited I modified the publications section on page slightly. These on electronics marked 9 of this report.
This report includes descriptions of basic semiconductor circuitry for accurate measurements of an insect's environment and behavior; some methods for using Ohm's law to calculate resistance in meter-recording circuits; an explanation of the characteristics of photoconductive and photovoltaic cells, thermistors, and pressure-sensitive microducers; and a presentation of schematics and examples of many simplified semiconductor circuits I have used to study the environment and behavior of the corn earworm moth.
