The Relationship Between Insect Visitors And Chemical Fragrance Composition Of Cypripedium Parviflorum Var. Pubescens In Central Virginia., Ruth Elkins
Student Scholar Showcase
Due to its rarity, little is known regarding which insects pollinate Cypripedium parviflorum var. pubescens, large yellow lady slipper orchids, and why they do so when offered no reward. Insect identification and fragrance composition data have been collected from two populations of large yellow lady slippers in Central Virginia for more than a decade. This research analyzed data in order to determine potential relationships between visiting insects and fragrance compositions of the orchid. The results of this research can be used to establish and protect populations of Cypripedium parviflorum var. pubescens.

A Chemical In Filter Paper Interferes With Trail Following Behavior In The Termite Reticulitermes Hesperus (Banks), Kathryn Vest
Student Scholar Showcase
Termites follow chemical trails. In previous experiments we dissolved and diluted chemicals in acetone to test if they elicited trail following. Each trail was a straight line across the arena drawn with 10 µl using a glass capillary (Microcaps). We noticed a minor but stable response to trails laid with pure acetone. The response could be caused by contaminated acetone or by a chemical in the filter paper (Watman #5) that lined our arena (petri dish, 10cm diameter). We could confirm that the termites respond to acetone alone. Soxkhlet extraction for 8 hours removed the signal from the filter paper. …
