Abstract
In order to investigate of contact toxicity and repellency properties of essential oils of Rosmarinus officinalis L. and Chrysanthemum cinerariaefolium L. against adults of German cockroach, an experiment was conducted as CRD in 2022. The essential oil of Rosemary and Pyrethrum applied for bioassay of repellency and lethality effects on German cockroaches in 6, 12, and 24 hours intervals. The death rate of cockroaches increased with the increase in the concentration of essential oil and also with time. The contact toxicity of Pyrethrum (with LC50 equivalent to 84.77, 24.92, and 11.39 µl cm-2, respectively, in time intervals of 6, 12, and 24 hours) was significantly higher than Rosemary essential oil. Also, the highest rate of death in both essential oils was observed 24 hours after essential oil application. On the other hand, Rosemary and Pyrethrum essential oil in different concentrations caused the removal of different percentages of the cockroach population. The highest percentage of removal occurred in concentrations of more than 1.56 µl cm-2 of rosemary essential oil, which caused the removal of nearly 60% of the cockroach population. Considering the frequency of growth and compatibility of Pyrethrum and Rosemary, with Iran weather conditions and the possibility of their mass production, the essential oil of these plants can be considered as a suitable alternative to control cockroaches in an integrated management program.
