摘要：

Some populations of the grasshopper, Myrmeleotettix maculatus, are polymorphic for the presence of B chromosomes. In a culture derived from a population near Aberystwyth in Wales, it was found that grasshoppers with two or more B chromosomes took longer to develop from egg diapause to adult than those with one or none. There was no significant difference between OB and lB grasshoppers. The significance of these findings for the maintenance of the B chromosomes is discussed. © 1979 The Genetical Society of Great Britain.
