This is an empirical test of the feasibility of introducing genes into population. Finding a suitably neutral genetic marker proved problematic, but when this was solved, a number of important observation were made. Release ratios were important because some did not lead to the fixation of the introduced marker gene. Additionally, there was linkage dissociation between the markers and the element leading to the spread of an unmarked element. This effect will have to be characterized before a release protocol is implemented.
Significant challenges remain in population analysis of vectors.
There are general patterns to vector population structure that can be observed on several levels, for example, breeding sites, adult resting places, that indicate high dispersal but local variation. The significance of these results with respect to disease transmission needs to be demonstrated. Variances between critical genetic properties that confer vector competence need to be analyzed. The analysis of pathogen population structure may factor significantly in vector competence. Because the problem is complex, it is necessary to fix the effects of the pathogen population structure in order to analyze differences in vectors.
