“…Furthermore, (20) reported that few makeup products like citric acid were applied to the skin of rats, mosquitoes were attracted towards, the results showed that Anopheles gambae was less attracted than Aedes aegypti towards the makeup products. The current study is similar to those conducted by (8), in which the citric acid was found to be effective on all tested stages of Aphis craccivora. This effectiveness was barely noticed after 2 hours, yet it increased after 12 hours .…”

“…The successful use of active components depends on its correct formulation into an equipment which can be applied for output protection with safety to those applying materials to the environment and to human, and animal life (7)(8)(9). Researchers have recently turned to the use of alternatives to pesticides that are effective against insects that remain for a short period and are safe and cheap, such as inorganic salts and antioxidants.…”

The chemicals materials were used to study the effect of citric acid, detergents, sodium carbonate, sodium bicarbonate on the vitality of the third stage of mosquito Culex pipiens molestus. The highest larvicidal efficacy was established from citric acid solution followed by detergents solution, sodium carbonate, sodium bicarbonate with (LC 50 ) values 2096, 2715, 13930, 13960 ppm respectively. The concentration of 1000 ppm of citric acid showed a fatal effect on the third stage larvae of mosquitoes which gave a mortality percent of 100% on the second day of the treatment. It was followed by the concentrations of 750 ppm and 500 ppm respectively which caused the death of all larvae on the fifth and sixth days respectively. On the other hand, the concentration of 1500 ppm for the detergents killed 100% of the larvae on the third day of treatment. Then, it was followed by the concentration of 1000 ppm, leading to the destruction of all the larvae on the fifth day of the exposure. As for the use of sodium carbonate, the mortality percentage reached to 100% at a concentration of 8000 ppm on the third day of treatment followed by the concentration of 6000 ppm, which led to a 100% killing rate on the sixth day of treatment. While the less impact of studied chemicals was sodium bicarbonate, the 8000 ppm concentration of which caused 84.21% mortality rate of larvae on the fourth day of treatment.

“…The objective of this research paper was to determine the acaricidal efficacy of three formulations for three safe compounds derived from plants, jojoba oil 90 % EC and the previously prepared Baraka oil 75 % EC [22] and citric acid 90 % SP [23][24][25] on T. urticae. In order to move a new step in our ongoing program for obtaining new, safe and eco-friendly active ingredients and formulating it in a local formulation to be used for pest control after completing the necessary required studies.…”

Jojoba oil has an acaricidal effect on Tetranychus urticae adult female mortality, as well as antifeedant, larvicidal, and physiological effects on other insects. The goal of this study was to formulate jojoba oil to compare its effectiveness with Baraka oil, and citric acid formulations against the two-spotted Spider Mite T. urticae. A new local jojoba oil formulation was developed as an emulsifiable concentrate (EC). Three formulations for (jojoba oil, Baraka oil and citric acid) were put to the test on eggs of T. urticae. Jojoba oil and Baraka oil were used as emulsifiable concentrates (ECs) while citric acid was used as soluble powder (SP). Jojoba oil EC showed the highest result followed by Baraka oil EC, and citric acid SP. The EC50 values were 376 ppm for jojoba oil and 1305 ppm for Baraka oil (ECs), respectively. Under greenhouse conditions, jojoba oil EC was evaluated on egg hatching and individuals of T. urticae at 1000 and 2000 ppm. After 14 days of treatment, egg hatching was totally suppressed, whereas individual inhibition was 84.4 and 91.4 % for both concentrations, respectively. As a result, the two-spotted spider mite can be combated with the new jojoba oil EC formulation.

Some insects cause high losses of the common bean during storage, namely, Acanthoscelides obtectus Say. Chemical insecticides are commonly used to control insects, but their overuse adversely affects the environment and consumers' health. There is, therefore, the need for an alternative control method. This study was aimed to evaluate the chemical characterization and insecticidal property of Moringa oleifera seed extract on the developmental stages of A. obtectus in stored beans. Three types of M. oleifera seed extracts, namely methanol, ethanol and acetone extracts, were used at doses of 12.5, 25 and 50 µl/ml each. HPLC-MS was used to characterize these extracts. The toxicity of extracts against the adults, the number of eggs and the viability rate of laid or emerged eggs of A. obtectus were evaluated. The results show that M. oleifera seed extract is rich in Hesperidin, Quinic acid, gallic acid, protocatechuic acid, 4-OH benzoic acid, cynaroside, isoquercitrin, cosmosiin, quercitrin, luteolin, naringenin, salicylic acid, Apigenin and Fumaric acid. The acetone extract, from day 2, showed a 100% mortality rate in all doses compared to about only 14% in the control treatment. The number of eggs laid in control (236.67) was higher than the null (0) in acetone treatment at 50 µl/ml. M. oleifera seed extracts contain chemical molecules. They significantly reduced the damage caused by A. obtectus on stored P. vulgaris grains. Therefore, they can be used as an alternative to chemicals for the protection of stored foodstuffs.
