“…[13][14][15] Furthermore, in treating anorexia, heart disease, carmine infections, healing, and reducing the pain of oral aphthous are other effective properties of this oil. 10,16 In agriculture, the field of pest control, properties like insecticidal, ovipositional, antinutritional, and repellent activities of the GO [17][18][19][20][21] and CO 22,23 have been investigated on different groups of pests. However, the use of oils has been limited due to their volatility, poor water solubility, and rapid oxidation capacity, chemical instability against heat, humidity, oxygen, and light.…”

Garlic oil (GO) and cinnamon oil (CO) was successfully loaded in chitosan (CS) based polymeric nanoparticles (NPs). Fumigant, contact toxicities and persistent efficacy of these new Chitosan nano particles (CSNPs) were examined against Tribolium castaneum (T. castaneum) as a common stored product pest. Different ratios of polymer to sodium tripolyphosphate cross-linker were applied for NPs preparation. Stability of CSNPs loaded with oils was examined for 4 months. Bioassay tests were used to determine LC 50 values for fumigant toxicity evaluation and contact effects on red flour beetle, T. castaneum. The optimized CSNPs containing GO and CO had the particle size of 231.1 ± 7.5 nm and 303.4 ± 10 nm with encapsulation efficiency of 76.78% and 86.81%, respectively.Characterization results based on transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) indicated the successful formation of CSNPs with spherical morphology, amorphous property, and high stability during the storage time. LC 50 index of pure oils and their nanoformulations suggested that CSNPs loaded oils have higher fumigant and contact effects on T. castaneum in a lower concentration than pure oils. Lethal effectiveness of CSNPs loaded GO and CO against T. castaneum were 18 and 20 days, respectively. However, GO and CO pure oils lost their efficacy in 10 and 14 days after exposure, respectively.

“…Traditional methods of protecting stored grain include using the insecticidal properties of Neem extracts, mixing the grain with ash or sand, using vegetable oils, combining ash and oil into a soap solution or treating the cowpea pods with smoke or heat. Certain plant species were tested for their insecticidal properties under laboratory conditions against C. Maculatus (Kathirvelu et al, 2019) reported that the formulation manifested the control over test insects.…”

Laboratory experiment was carried out to evaluate the efficacy of Stembark and pod powders of locust bean (Pakia biglobossa) and their appropriate concentration for the management of cowpea weevils (Callosobruchus maculatus F.). Spintor (0.125%) and dust (0.125 g) was used a positive control and untreated cowpea seeds serving as negative control. The experiment was laid in Completely Randomized Design (CRD) comprising of Stem bark powder (1 g, 3 g and 5 g), Pod powder (1 g 3 g and 5 g), spintor 0.125% Dust (0.125 g) and control. These were applied to 100 g healthy cowpea seeds and repeated three times. Contact activity of the plant products were evaluated and data collected were subjected to analysis of variance (ANOVA) using SPSS software (version 23) and means were separated using NDMRT at 1% and 5% probability level. The results showed that higher concentration (5 g/100g) of plant products significantly (P<0.05) caused mortality of C. Maculatus after 24 (2.33), 48 (2.66), 72 (2.66) and 96 hours (3.00) by contact toxicity compared to other treatments. Similarly, higher concentration (5 g/100g seed) of the pod powder significantly (P<0.05) decreased oviposition (3.67), adult emergence (3.66), percentage seed damage (1.73%), number of exit holes (6.33) and weight loss (1.03%) compared to untreated cowpea seed that record 58.00, 54,67, 19.67%, 56.33 and 13.87%, respectively. It was concluded that germination of the treated seeds was not affected negatively. The Pod powder of P. biglobossa could be recommended as suitable alternatives to chemical pesticides to be used as contact protectant against C. maculatus on stored cowpea seeds.
