Experiments and Studies for Members in Advanced Units

The following experimental studies may require too much time or apparatus to be conducted as demonstrations. How- ever, they are within the realm of advanced members to conduct as special projects. Outline guides for the topics marked with an asterisk(*) are available from the 4-H Ento- mology State Specialist.

1. *Insect survey of a particular plant--An observational study to show the diversity and change in insect populations on a plant over a period of time.
2. Light trap survey of the sod webworm--Light trapping can provide information for timing the application of insecticide controls. Information will vary depending on the geographic area.
3. The effects of diet on insects--For instance, rear cecropia moths on different host plants to observe differences in size and/or color of the caterpillars and moths. Does host plant affect the number and/or viability of eggs laid by the moths? Is the life cycle shorter or longer when the insect is reared on different plants, etc.?
4. Genetics--Drosophila flies and instructions are available from biological supply houses for genetic experimentation and study.
