Response of the Adult Screwworm (Diptera: Calliphoridae) to Bacteria-Inoculated and Incubated Bovine Blood in Olfactometer and Oviposition Tests1

Abstract
Olfactometer tests in the laboratory with bacteriainoculated and incubated defibrinated bovine blood showed that Proteus rettgeri attracted more adult screwworms, Cochliomyia hominivorax (Coquerel), than did 3 other Proteus species or species from 6 other genera of bacteria. A combination of Bacillus species stimulated greater oviposition from gravid females than did Proteus or a combination of Bacillus species plus Proteus Species.
