Abstract:

DEctomyelois ceratoniae (Pyralidae) is the main insect pest attacking dates in field and storage in Tunisia. Postharvest protection is relied on fumigants. This work investigates fumigant toxicity of 2-hydroxypropyl-beta-cyclodextrin (HP-β-CD) loading Rosmarinus officinalis essential oil and its major constituents (1,8-cineole, α-pinene, camphor, borneol) against E. ceratoniae larvae and adults. Results revealed that mortalities reached 56.86; 60.71; 64.28; 50 and 75% respectively for the crude essential oil, α-pinene, camphor, borneol and 1,8-cineole after 30 storage days at the concentration 90 µl/l air. Also, results indicated that 1,8-cineole, camphor and α-pinene showed the strongest inhibitory effects of adults emergence.
