The population in geueral is closely massed around biotype 7 as in previous instances. I do not know how many survived the cold, dry winter in this location, but when I saw the product of the native population and the introduced materials in the first summer generation in 1908 there was little trace of the introduced materials, with the exception of an isolated group of females of biotype 13, as is shown in the record in figure 96. The second census of the season showed the same imiform population, but present in it were divergent isolated groups of biotype 1 in both sexes, 6 and 12 in the males, and extreme 8 in the females. These groups were strong in proportion to the population (fig. 97)..
