Comparison of Trap and Equine Attraction to Mosquitoes.

Abstract: Mosquitoes are pests of horses, but mosquito trap efficacy data, especially the ability of traps to protect horses, are lacking. Studies were conducted to investigate the comparative attraction between traps and horses, increase trap attraction by adding horse odors to the airstream of a trap, determine the spatial distribution of adult mosquitoes, estimate the numbers of mosquitoes feeding on horses, determine the relative attraction of horses to mosquitoes, and estimate the range of mosquitoes' attraction between two horses. When a horse and a mosquito trap were placed 3.5 m apart, there was a significant reduction in mosquitoes entering the trap. Adding horse odors to the airstream of a trap produced equivocal results because the horse providing the odors influenced the trap catches. Mosquitoes were not evenly distributed across the study site, which emphasized the importance of trap placement. Vacuuming mosquitoes from the horses in different seasons demonstrated that 324 and 359 mosquitoes per hour were feeding during the two studies. Separate analysis of data from the two horses vacuumed simultaneously revealed that one horse attracted twice as many mosquitoes as the other. This caused the results of a study to determine the attraction range of two horses moved from 3.5 to 20.4 m apart to be inconclusive.

This research investigates the ways in which mosquitoes are attracted to horses and compares them to the efficacy of mosquito traps. The study explores how changing trap parameters and horse-related factors can influence mosquito attraction, aiming to improve pest control strategies.

Comparison between Traps and Horses

  • The study initiated by comparing the attraction between mosquitoes, horses, and traps. A significant observation was that when a horse and a mosquito trap were placed close to each other (3.5 meters apart), fewer mosquitoes were drawn towards the trap. This suggests that the presence of the horse interfered with the trap’s efficacy.

Enhancing Trap Attraction with Horse Odors

  • The researchers tried to enhance the attraction of the mosquito trap by adding horse odors into the trap’s airstream. However, the results were inconsistent. It turned out that the specific horse providing the odors had a significant influence on the number of mosquitoes caught in the trap.

Spatial Distribution of Mosquitoes

  • The study also determined that mosquitoes were not uniformly distributed across the study site. This highlighted the importance of the correct placement of mosquito traps to maximise their efficiency.

Estimation of Mosquito Feeding on Horses

  • By vacuuming mosquitoes off horses at different seasons, the researchers estimated that there were around 324 to 359 mosquitoes feeding on horses per hour during the course of the two separate studies.

Relative Attraction of Horses to Mosquitoes

  • The team also discovered that different horses attracted different numbers of mosquitoes. The data showed one horse attracted twice as many mosquitoes as another during the same period.
  • On trying to determine the range of mosquitoes’ attraction between two horses positioned between 3.5 meters and 20.4 meters, they couldn’t ascertain concrete results due to the differing attraction levels between the horses.

Conclusion

  • In conclusion, this research reinforces the complexity of mosquito attraction and trapping, emphasising the need for further studies to refine mosquito control strategies. Different factors like trap placement and odors emitted can significantly impact trap efficacy, and horses themselves can also vary in their attractiveness to mosquitoes.
