Interpretive Summary: Essential oils from Seseli gummiferum (Apiaceae) was investigated for the bioinsecticidal activity. Seseli L. is one of the largest genera in the Apiaceae and the total of 13 genera was represented in Turkey. In continuation of our studies on screening essential oil from medicinal plants, S. gummiferum subsp. ilgazense essential oil was investigated for its larvicidal activity against 1st instar Aedes aegypti.

Technical Abstract: There has been renewed interest in finding the use of natural plant extracts as alternative sources for public health pesticides since these extracts and their constituent compounds are normally considered safer than chemicals for human health and the environment. Mosquitoes are vectors for many pathogens and parasites that cause human diseases including dengue, yellow fever, West Nile, chikungunya, and filariasis and malaria which cause high rates of human morbidity and mortality under extremely conditions. Plants are an excellent source of candidate for mosquito control agents because they constitute a rich source of bioactive chemicals, environment-friendly and biodegradable. The present work reports on the larvicidal activity of the essential oil of Seseli gummiferum Pall. ex Sm. subsp. ilgazense A. Duran, O. Cetin & M. Ozturk (Apiaceae) against Aedes aegypti larvae. Essential oils showed 100 and 70% mortality at 125 and 62.6 ppm, respectively, and no mortality at 31.25 ppm. Aerial parts of S. gummiferum subsp. ilgazense were subjected to hydrodistillation to yield the oil (0.57%). Essential oil was analyzed by GC-FID and GC-MS techniques. The main constituents in the oil from aerial parts were sabinene (28.8%), germacrene D (9.5%) and '-pinene (7.2%).
