Abstract: I experimentally tested the effects of three aspects of insect communities with plant diversity - insect species richness, insect species density, and percent herbivores in the insect community. I intended to examine the potential effects the insect community in general, and the herbivore community specifically, may have in aiding the plant communities' ability to resist ecological invasions. The relationship between plant diversity and the three tested statistics revealed much about the community structure. I carried out the experiment by sampling 18 1.5 x 1.5 meter plant plot "communities" for the insects present, each plot with a variety of plant diversity. Both insect richness and density revealed strong positive yet insignificant relationships with plant diversity, while the percent herbivores yielded no relationship. I believe the small sample size accounts for the insignificant but distinctly positive results, while a variety of community factors indicate the truth of the herbivore results. For example, the potential effects of parasites and predators on insects may limit the ability of the insect community to respond directly to the diversity of the plant community. In general, the results disagree with those found in other studies. I believe they indicate that herbivory is not a significant factor in the ability of plant communities to resist ecological invasion, because the response to increasing plant diversity was not significant.
