    The small droplet size could increase the absorbed ingredients and high stability. The star anise nanoemulsion was determined optimum efficacy, with a 1% concentration resulting in the highest knockdown and mortality rate of 100%. Its KT<inf>50</inf> and mortality effective values were 28 min and 36 times, respectively. Furthermore, the adult stage of houseflies is found to be susceptible to star anise nanoemulsion. In contrast, cypermethrin was less toxic to it, with a high KT<inf>50</inf> and resistance to adult houseflies. Consequently, the star anise nanoemulsion could be developed into an efficient and safe environment for controlling housefly populations.

    The combination of four plant essential oils (EOs) from star anise, citronella grass, lemon grass, and cinnamon was evaluated for repelling American cockroaches by the dual-choice method. A combination of star anise + citronella grass had a repellency rate of 95%. In contrast, combinations of star anise + lemon grass and star anise + cinnamon were effective between 73% and 69%, but the synthetic chemical repellent (12% DEET) was less effective at 59%. Therefore, the essential oils formulae had a high potential for effective use and, further, are harmless for healthiness and the environment. Thus, they can replace more toxic synthetic insecticides.
