Abstract:

Fumigation for 4 h with acetaldehyde (Aa) vapor in an atmosphere containing 25-35% carbon dioxide (C0₂) increased the mortality of Myzus persicae (Sulzer) ca. 3-fold as compared with Aa fumigation alone. All aphids were killed by treatment with 1% Aa in 50-60% CO₂ or 1.5% Aa in 35% CO₂ as compared to 32 and 92% mortality, respectively, in treatments without CO₂, Fumigation with Aa vapor in a low oxygen (1-2%) atmosphere did not increase the mortality rate of the aphids.
