| Summary: | Continued use of chemical insecticides causes toxicity to non-target organisms, pest resistance and environmental pollution around the world. Nanocapsules of botanical insecticides are a suitable alternative for this target. The major constituents of Eucalyptus extract were determined by GC-MS: 1,8-cineole (70.94%) and 1,2-benzenedicarboxylic acid (6.08%). The Characterization of nanocapsule was investigated by dynamic light scattering, Zeta potential, scanning electron microscope, optical microscope and FTIR. The mean particle size distribution of nanocapsule is 380 nm and zeta potential of −26.36 ± 5.31 mV was obtained. It could be observed that nanocapsules have a spherical shape. To determine the insecticides of the nanocapsule with loads Eucalyptus extract was impregnated with concentration (0, 10, 15, 25, 35, 50 mg/ml) for 12, 24 and 48-h after exposure. The results indicated, that over time encapsulation exposure from 12 to 48 h, the highest time was comparatively more susceptible (LC50 = 14.93 mg/ml). |
