Abstract:Field releases of a tachinid parasite, Lixophaga diatraeae (Townsend), were made in July and September 1973 to evaluate its potential for suppressing populations of the sugarcane borer, Diatraea saccharalis (F.), in Louisiana. Sugarcane borer larval collections were obtained from the field every 2 wk to determine host density levels and percent parasitism. Release of 1418 parasites/ha did not decrease host density. Sugarcane borer larval populations steadily increased to levels above that required to cause economic loss as the crop season progressed.
Screen cage experiments were conducted from June through November 1974 to further evaluate the effectiveness of L. diatraeae. Parasitism was low following an August release; however, 8- to 9.day-old parasites were more efficient than those 5 days old. Percent parasitism of sugarcane borer larvae by L. diatraeae was higher following an October release than when releases were made in August. A significant positive correlation between percent parasitism and host population density was detected in screen cage experiments but not in the field test.
