Summary: This study evaluated the chemical composition and insecticidal and acaricidal potential of the essential oil extracted from the resurrection plant Myrothamnus moschatus from Madagascar. The results showed that the oil contained abundant volatile compounds and demonstrated good insecticidal and acaricidal activities against various pests and vectors. This suggests that the plant could be a potential source of botanical insecticide ingredients and contribute to the African economy and local farmers.

Summary: In recent years, there has been a focus on developing essential oil-based biopesticides as alternatives to traditional chemical products in the agrochemical industries. The genus Mentha, which includes various species with diverse biological activities, has shown promise as a source of pesticidal agents. This study specifically investigated the insecticidal activity of the essential oil from a rare chemotype of Mentha aquatica, which demonstrated high efficacy against multiple insect species. These findings suggest the potential use of this plant or its major volatile compounds as novel ingredients in botanical insecticides and pesticides.

Summary: This study evaluated the efficacy of n-hexane extracts of Artemisia scoparia and Anisomeles indica against Culex quinquefasciatus. It also assessed the predatory effects of the diving beetle, Agabus cybister, against the mosquito larvae. The results showed that both plant extracts had mosquitocidal activity and the diving beetle effectively controlled the larvae.
