Effectiveness of nicotine as a natural chemical deterrent to pollination. (South Carolina Junior Academy Of Sciences Abstracts).

This experiment attempted to determine whether or not nicotine functions as an attractant or repellant in moths, and whether or not prior exposure is a factor in this response. There were two main parts in the experiment to simulate the possible interaction with nicotine in the environment. The initial part of the experiment tested odor attraction or repulsion at a distance. A wind tunnel was used to deliver odors to nave moths on the different diets. The second part of the experiment was performed in a flight cage. A small array of flowers with and without nicotine was randomly placed in a small wire holder. While allowing the moths to feed freely, their responses to the different flowers were digitally recorded. Unfortunately the mortality of the moths increased dramatically over an isolated two-day period. This precipitous decline in viable larvae substantially reduced the number of available subjects and effectively prohibited further experimentation. The deaths are likely due to an aberrant bacterial strain, or possible over-consumption of nicotine. An infectious bacteria strain seems to be the most likely cause considering that all of the larvae died over a very limited amount of time regardless of their age.
