[Evaluation of sandfly control measures]

Area of Science:

• Medical Entomology
• Vector Control
• Public Health

Background:

• Sandflies are vectors for diseases like leishmaniasis.
• Insecticide resistance and environmental changes impact sandfly populations.
• Effective vector control strategies are crucial for disease prevention.

Purpose of the Study:

• To evaluate the effectiveness of implemented control measures on sandfly density.
• To compare sandfly populations before and after intervention in Recanto Marista, Paraná.
• To identify dominant sandfly species and their preferred ecotopes.

Main Methods:

• Sandfly collections using Falcão traps from May 2005 to April 2006.
• Comparison with data from April 2001 to September 2002.
• Sampling conducted inside homes and hen sheds, weekly, 4 times/month, 10 PM-2 AM.

Main Results:

• A decrease in sandfly density was observed between 2001-2002 (1,653.5/hour) and 2005-2006 (1,113.8/hour).
• Nyssomyia neivai predominated (75.4%), followed by N. whitmani, M. migonei, and P. fischeri (99.7% combined).
• Hen coops were the primary ecotope (88.7%), but density reduction was most notable in homes.

Conclusions:

• Implemented control measures were effective in reducing overall sandfly density.
• Nyssomyia neivai remains the dominant species, highlighting the need for targeted control.
• Further monitoring is recommended to sustain reduced sandfly populations and prevent disease transmission.
