    Among the tested botanical extracts, Illicium verum (star anise) essential oil at 10% demonstrated the highest efficacy in disrupting normal pupal development. Only 65.00% of individuals successfully emerged as fully developed adults after a 10-day exposure period. A notable proportion exhibited transitional deformities, particularly malformed pupal-adult intermediates, indicating interference with metamorphic progression. In comparison, cypermethrin, a commonly applied synthetic insecticide at the same concentration, resulted in a lower mortality rate of 39.67% under identical experimental conditions. The superior performance of star anise oil highlighted its potential as a plant-derived alternative for insect control. These findings suggested that the incorporation of such natural products into integrated pest management strategies may reduce dependence on conventional synthetic chemicals.

    The knockdown and mortality of some compounds from natural oils (trans-anethole, eugenol and a combination of trans-anethole and eugenol) against adult houseflies (Musca domestica) compared with cypermethrin was investigated. The knockdown and mortalities were highest at 100% of 1% trans-anethole with KT50= 31 min and LT50 = 31 min. The mortality index of trans-anethole was 82.1 times that of cypermethrin. In contrast, 1% eugenol had knockdown and mortality was 36% and 0.5% trans-anethole + 0.5% eugenol had knockdown and mortality of 68%, with mortality indexes of 1.6 and 3.2 times versus cypermethrin. The trans-anethole high toxicity and low residue made it a superior control for houseflies.
