Termites cause important economic losses worldwide and insecticides are largely used to control termites, resulting in significant economic losses around the globe. The development of alternative termite control methods is motivated by concerns for the health of humans and the environment. Such knowledge would greatly help in optimizing termite management methods. However, few studies have documented the various effects that plant extracts may have on termites. Under laboratory conditions, we assessed has examined the numerous ways that plant extracts affect termites, we tried determining the median lethal concentration (LC50) circumstances of five extracts of natural plants including Spike Lavender (Lavandula latifolia Medik.), Clove (Syzygium aromaticum (L.), garlic (Allium sativum L.), Cinnamon (Cinnamomum verum) and Marjoram (Origanum vulgare L., Lamiaceae)), on the termites Reticulitermes spp. (Isoptera: Rhinotermitidae). When treated with different concentrations (0, 5, 10, and 15 μL/ L) of the five above-mentioned plants, over specific periods (1, 2, 3, 4, 5, 6, and 7 days). The results of the current study showed that the tested Plant Extracts could be discerningly arranged as follows: Garlic, Clove, Lavender, Cinnamon, and marjoram. The corresponding LC50 values were 17.274, 17.84, 18.823, 23.706, and 25.483 μL/L. On another hand, the LC90 values were 87.47, 90.434, 88.377, 133.321, and 132.296 μL/ L. As well as χ2 values were 0.0322, 0.4688, 0.5364, 0.7074, and 1.54, respectively. The current findings may aid in improving the management of termites, plant extracts against termites are efficient and offer various potential future sustainable development applications.
