Chemical composition and bioactivity of Lantana camara L. essential oils from diverse climatic zones of Kenya against leaf miner (Tuta absoluta Meyrick)

In recent years, essential oils (EOs) as alternatives to synthetic pesticides in managing pests have been assessed. The use of bioinsecticide in pest management is encouraged agroecology for a sustainable agricultural system. Essential Lantana camara L. leaves from different climatic zones Kenya were extracted by steam distillation and analyzed through GC-MS identify the compounds. contact toxicity and repellent activity EOs against invasive tomato pest, Tuta absoluta, were tested. toxicological assays performed following leaf-dip bioassay protocol, while repellency activity was using repellent response method phytophagous and data ANOVA test. It found that L. camara EO has good insecticidal with higher mortality (89%) on 2nd instar larvae dosage (0.01 µl/µl). repellence test also showed average (93.44%) effect µl/µl) EOs. According these results, of L. camara may well be sustainable, eco-friendly alternative synthetic insecticide T. absoluta program.
