Nanoparticles loading essential oils as alternative solution for the postharvest control of the date moth Ectomyelois ceratoniae (Pyralidae)
Published: 30 June 2021 by MDPI in The 1st International Electronic Conference on Entomology session Pest Management
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.
