Insecticidal Potential of Matricaria chamomilla’s Essential Oil and Its Components (E)-β-Farnesene, Germacrene D, and α-Bisabolol Oxide A against Agricultural Pests, Malaria, and Zika Virus Vectors

Agricultural and medical insect pests are damaging edible crops, spreading diseases, harming non-target fauna flora. Prominent polyphagous harass farmers in the agronomy sector, causing uncountable revenue corrosion. Ecofriendly phytopesticides can avoid consequences of bulk usage synthetic chemicals. In this study, toxic effect on third-instar larvae four different species (Spodoptera litura, Helicoverpa armigera, Aedes vittatus, Anopheles subpictus) bio-toxicity (NTF) (Stegodyphus sarasinorum Gambusia affinis) were evaluated using Matricaria chamomilla (Mc) essential oil (EO) its major phytoconstituents (Mc-MPCs). GC–MS analysis studied M. EO gathered 39 constituents, with (E)-β-Farnesene (24.3%), Germacrene D (9.4%), α-Bisabolol oxide A (10.2%) accounting for constituents. Remarkable larval death was seen H. armigera Ae. vittatus. addition, (E)-β-Farnesene, D, exhibited a relevant maximum target pest’s larvae. The Mc-MPCs tested terrestrial aquatic NTF. LC50 values S. G. affinis ranged from 922.65 to 1750.49 µg/mL. MPCs evidenced prospective phytopesticidal efficiency selected agricultural pests.
