Individuals from an inbred laboratory stock of Locusta migratoria were subjected to 40° C heat treatments. These involved both constant 40° C treatment and shorter periods of 5, 4, 3, or 2 days at the high temperature followed by a return to the lower temperature of 30° C. Chiasma frequency analyses revealed that a total of four different effects could be produced by the heat treatments at different stages of cell division: two of the effects involved increases and two involved decreases. Similar, though not identical, effects have also been obtained in the locus Schistocerca gregaria. The similarities and differences in the responses shown by these two species are compared and contrasted.
