Author Information
Author(s): Charles R. Bartlett, Erin R. Adams, Anthony T. Gonzon, Jr.
Primary Institution: University of Delaware
Hypothesis
What is the current diversity of planthopper species in Delaware, excluding Delphacidae?
Conclusion
The study found that Delaware is home to 62 species of planthoppers, significantly increasing the known diversity from just 7 species.
Supporting Evidence
- The number of planthopper species in Delaware increased from 7 to 62.
- 55 new state records were established during the study.
- The Chao1 estimator suggests that the true fauna may be around 74 species.
Takeaway
This study shows that there are many more types of planthoppers in Delaware than previously thought, with 62 species now identified.
Methodology
Specimens were collected and identified from Delaware and adjacent states, with abundance tallied by county and seasonally by two-week intervals.
Potential Biases
Specimen records were heavily biased towards New Castle County, where the main campus of the University of Delaware is located.
Limitations
Some female specimens could not be identified to species, and the study may not capture all species present in the region.
