In the context of frequency-dependent selection, the effect of conditioning the medium, by the previous culture of larvae of a given strain, on the survival of subsequent larvae of the same or different strains was measured. Six strains were sued, some inbred and some lines selected for low or high sternopleural bristles. The survival of larvae was not significantly less when the food had been conditioned by the same strain rather than by another strain, nor did conditioning by one strain have any special effect on the survival of another. The survival of lines on medium conditioned by the same strain was not less than on fresh medium, and in some cases was significantly greater.
在频率依赖型选择的背景下，测定了用给定品系的幼虫先前培养物对培养基进行预处理，对同一品系或不同品系后续幼虫存活的影响。使用了六个品系，其中一些是近交系，一些是针对低或高腹板刚毛进行选择的品系。当食物由同一品系而非另一品系预处理时，幼虫的存活率并没有显著降低，一个品系的预处理对另一品系的存活也没有任何特殊影响。在由同一品系预处理的培养基上，品系的存活率不低于在新鲜培养基上的存活率，在某些情况下还显著更高。
