AB  - INTRODUCTION: Plant essential oils (EOs) can be used as a feasible tool for 
      insect pest control. Nanoparticle formulations of plant EOs can improve the 
      efficiency and stability of EOs, as well as insecticidal potential. METHODS: In 
      this study, Carum copticum L. essential oil-loaded nanoparticles (OLNs) were 
      prepared via an oil-in-water emulsion, followed by droplet solidiffication via 
      ionic gelation using a cross-linker, sodium tripolyphosphate (TPP). The 
      nanoparticles were characterized by ultraviolet and visible (UV-Vis) 
      spectrophotometry, Fourier-transform infrared spectroscopy (FTIR), laser light 
      scattering (LS), transmission electron microscopy (TEM), and scanning electron 
      microscopy (SEM). Moreover, the insecticidal activity of C. copticum EO and OLNs 
      was evaluated against Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) and 
      Tribolium confusum Jacquelin du Val. (Coleoptera: Tenebrionidae). In addition, 
      their effectiveness was assessed on the progeny production of tested insect 
      species. RESULTS AND DISCUSSION: The loading efficiency ranged from 34.33 to 
      84.16% when the chitosan to EO weight ratio was 1:1.25 and 1:0.5, respectively. 
      The loading efficiency decreased with increasing EO content in the nanoparticles. 
      The OLN particles exhibited spherical shape. The particle size was in the range 
      120-223.6 nm and increased with the increase of EO to chitosan ratio. So that the 
      largest mean particle size (223.6 nm) was reported in the 1:1.25 weight ratio of 
      chitosan to the EO. The mortality percentage of R. dominica and T. confusum 
      adults were 74 and 57% when exposed for 7 days to 2000 mg/kg of OLNs at the 
      1:1.25 weight ratio, while EO caused 62 and 44% mortality on both insect species, 
      respectively. Therefore, OLNs can potentially improve the insecticidal activity 
      of C. copticum EO and could be applied to facilitate control of stored-product 
      insect pests.
