Burning dry dormant pasture grass was tested as a means of controlling the mosquitoes Aedes nigromaculis (Ludlow) and Aedes melanimon Dyar by destroying their eggs. Test plots containing Bermuda grass (Cynodon dactylon) were ignited and allowed to burn. The method, however, did not significantly reduce mosquito larval production. Temperature measurements with heat sensitive, lacquered probes showed that lethal temperatures are often not attained near ground level where most eggs are deposited.
