Synthesis, characterization, and evaluation of derivatives from cardanol as repellents/pesticides agents of Liriomyza sativae (Diptera: Agromyzidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) on melon plants

Hydrogenated cardanol derivatives were evaluated as potentially active insecticides/repellent agents against insect pests such Liriomyza sativae (Diptera: Agromyzidae) and Bemisia tabaci biotype B (Hemiptera: Aleyrodidae). Benzoylation, acetylation, methylation made on the hydrogenated aromatic ring to synthesize ingredients with potential insecticide action. Nuclear magnetic resonance spectra (13C 1H NMR) infrared (IR) proposed chemical elucidation of products. The production melon seedlings was each synthesized products, benzoylated 3-pentadecylphenol, acetylated methylated 3-pentadecylphenol applied by glass sprayer. Phytotoxicity evaluations carried out, noting that all plants showed burnt leaves except for concentration 1% which remained healthy look. insecticidal efficacy well repellent dissuasive effects a completely randomized design (DIC) complete block (DBCA) six treatments, five four replicates respectively. compounds derived from did not present activity in DBCA L. sativae; however, they had noticeable effect oviposition index (IPO).
