abstract = "Botanicals, such as essential oils (EO) and their compounds, are considered a viable ecofriendly
alternative to synthetic insecticides, which threaten human health and ecosystem functioning.
In the present study, we explored the potential use of two EO compounds, trans-anethole (phenylpropanoid)
and S-(+)-carvone (monoterpene ketone), against gypsy moth larvae (GML), a serious
pest of deciduous forests and orchards. GML feeding, survival, molting, and nutritional physiology
were assessed at different compound concentrations and compared with the effects of the commercial
botanical product NeemAzal®-T/S (neem). The impact of botanicals on GML feeding was assessed
by the leaf-dipping method and showed the highest antifeeding activity of neem in the no-choice
assay. GML that were offered a choice were deterred by anethole and attracted by low concentrations
of carvone and neem. Ingestion of botanicals was more effective in inducing mortality and reducing
molting than residual contact exposure. Anethole and carvone were better toxicants but worse growth
regulators than neem. Assessing nutritional indices revealed reduced growth, consumption, and
food utilization in larvae fed on botanical-supplemented diets. The highest metabolic cost of food
processing was recorded in carvone-fed larvae, which exhibited a negative growth rate. The results
suggest that anethole and carvone might be used as control agents against GML.",
