“…† The microstructure of epicuticular wax before and after PS MNP treatment was obtained using SEM. Since n-alkanes and esters are the most abundant components in crop cuticle waxes, 40,41 herein, hexatriacontane (C 31 H 64 ) and lauric acid, stearyl ester (C 30 H 60 O 2 ) were chosen as model compounds for n-alkanes and esters in epicuticular wax, respectively. And, their interaction with PS MNPs was assessed using Raman and Fourier transform infrared (FTIR) spectroscopy to explore the effects of PS MNPs on epicuticular waxes at the molecular level.…”

“…Tetramethylsilane (TMS) was used as the internal reference (δ 0.00). The high resolution mass spectra Wax esters are biodegradable, non-toxic, and are obtained from renewable sources [25] including vegetable oil crops such as olive [26], soya [27] and sunflower [28]. Similar esters of different chain lengths may also act as insecticides.…”

Bioassay-guided fractionation of an ethanolic extract of the aerial parts of Dolichandra cynanchoides Cham. (Bignoniaceae) led to the isolation of a natural wax with anti-insect activity against Spodoptera frugiperda (Noctuidae) and Epilachna paenulata (Coleptera). The compound was identified spectroscopically as an ester of a C27 fatty acid and a C25 alcohol, pentacosyl heptacosanoate (1). The effective doses of 1 for 50% feeding inhibition (ED 50 ) of S. frugiperda and E. paenulata were 0.82 and 8.53 µg/cm 2 , respectively, in a choice test, while azadirachtin showed ED 50 of 0.10 and 0.59 µg/cm 2 , respectively. In a no-choice test, both insects refused to feed on leaves treated with 1 at doses of 0.1 µg/cm 2 or greater inhibiting larval growth and dramatically reducing survival. The lethal doses 50 (LD 50 ) of 1 were 0.39 and 0.68 µg/cm 2 for S. frugiperda and E. paenulata, respectively. These results indicate that 1 has potential for development as botanical insecticides. Similar esters might be obtainable in large quantities as many edible crops produce wax esters that are discarded during food processing. Research on these materials could lead to the detection of similar waxes with insecticidal activity.
