The gypsy moth (Lymantria dispar L. (Lepidoptera: Erebidae)) is a serious pest of hardwood
forests. In the search for an environmentally safe means of its control, we assessed the impact
of different concentrations of essential oils (EOs) from the seeds of three Apiaceae plants (anise
Pimpinella anisum, dill Anethum graveolens, and fennel Foeniculum vulgare) on behavior, mortality,
molting and nutritional physiology of gypsy moth larvae (GML). EOs efficacy was compared with
commercial insecticide NeemAzal®-T/S (neem). The main compounds in the Eos were trans-anethole
in anise; carvone, limonene, and -phellandrene in dill; and trans-anethole and fenchone in fennel
seed. At 1% EOs concentration, anise and fennel were better antifeedants and all three EOs were more
toxic than neem. Neem was superior in delaying 2nd to 3rd larval molting. In the 4th instar, 0.5%,
anise and fennel EOs decreased relative consumption rate more than neem, whereas all three EOs
were more effective in reducing growth rate, approximate digestibility and efficiency of conversion
of food into body mass leading to higher metabolic costs to GML. Decrease in consumption and
metabolic parameters compared to control GML confirmed that adverse effects of the EOs stem from
both pre- and post-ingestive mechanisms. The results indicate the potential of three EOs to be used
for gypsy moth control.
