Various electronic databases were investigated for choosing reliable researches from 1990 to 2021. In total, 18 papers were selected among the 300 papers. Totally, 26 plants were evaluated in the published studies. Plants included Thymus vulgaris, Origanum vulgare, Mentha piperita, Syzygium aromaticum, and plant components of Thymol, Carvacrol and Linalool have the highest frequency in the papers studied. Maximum mortality and repellency of up to 100% were reported for the essential oils of Tagetes patula, Schinus molle, and plants of Cinnamomum sp. Cymbopogon martinii, Mentha piperita, Salvia rosmarinus, Thymus vulgaris, Origanum vulgare, Nepeta cataria.
