                                    Citation: Manoukis, N., Butail, S., Daigo, S.L., Paley, D.A., Ribeiro, J.M. 2014. Stereoscopic video analysis of Anopheles gambiae behavior in the field: challenges and opportunities. ACTA TROPICA. 132(S):80-85.Interpretive Summary: • Tracking individual swarming mosquitoes is important for basic and applied reasons
• Challenges include image capture, tracking methods and analysis of resulting data
• We review approaches to address problems in those areas
• We find that vertical oscillations of males vary less in larger swarms
• Results like these will be important for release-based control methods
                                Technical Abstract: Advances in our ability to localize and track individual swarming mosquitoes in the field via stereoscopic image analysis have enabled us to test long standing ideas about individual male behavior and directly observe coupling. These studies further our fundamental understanding of the reproductive biology of mosquitoes. In addition, our analysis using stereoscopic video of swarms of the African malaria vector Anopheles gambiae have produced results that should be relevant to any “release-based”
method of control including Sterile Insect Technique (SIT) and genetically modified male mosquitoes (GMM). The relevance of the results is primarily due to the fact that any mosquito vectors released for control are almost certainly going to be males; further, for SIT, GMM or similar approaches to be successful the released males will have to successfully mate with wild females. Thus, understanding and potentially manipulating the mating process could play a key role in future control programs. Our
experience points to special challenges created by stereoscopic video of swarms. These include the expected technical difficulties of capturing usable images of mosquitoes in the field, and creating an automated tracking system to enable generation of large numbers of three-dimensional tracks over many seconds of footage. Once the data are collected, visualization and application of appropriate statistical and analytic methods also are required. We will discuss our recent progress on these
problems, give an example of a statistical approach to quantifying individual male movement in a swarm with some novel results and suggest further studies incorporating experimental manipulation
and three-dimensional localization and tracking of individual mosquitoes in wild swarms.
