New Nebraska mosquito distribution records.

Area of Science:

• Entomology
• Vector-borne disease ecology
• Zoology

Background:

• Nebraska's mosquito fauna requires ongoing documentation to understand species distribution and potential disease vector presence.
• Previous surveys have identified a significant number of mosquito species within the state.

Purpose of the Study:

• To document new state and county distribution records for mosquito species in Nebraska.
• To update the known mosquito species list for Nebraska, including the identification of invasive species.

Main Methods:

• Larval mosquito collections were conducted throughout Nebraska in the year 2000.
• Species identification was performed using established taxonomic keys.
• Geographic distribution data, including state and county records, were recorded.

Main Results:

• Two new state distribution records were established for Ochlerotatus epactius and Anopheles perplexens.
• The presence of Culiseta melanura was confirmed, increasing the total reported mosquito species in Nebraska to 50.
• Fifteen new county records for 10 mosquito species were documented.
• The first report of Aedes albopictus from Lancaster County was noted, representing its westernmost collection in Nebraska.

Conclusions:

• The 2000 collections significantly expanded the known distribution of several mosquito species within Nebraska.
• The findings contribute to a more comprehensive understanding of mosquito biodiversity and the potential spread of invasive species in the region.
• Continued surveillance is crucial for monitoring mosquito populations and assessing public health risks.
