Globally, around 2000 plant species are used against pest control. The utilization of botanicals is considered the most economic and biodegradable methods for the control of stored grains pests. Therefore, the current study was carried out to investigate the repellency potential of five botanicals against Callosbruchus maculatus F. in Haripur, Pakistan. The concentrations of Azadirachta indica L., Nicotiana tabacum L., Melia azedarach L., Nicotiana rustica L., and Thuja orientalis L. were, i.e., 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0% in four replicates to establish contact effects. The data were recorded after 1, 2, 3, 6, 24, 48, 72, and 96 hours. The repellency effect of these plant species against C. maculatus were increased in both the time- and dose-dependent manner, and highest effect was observed at 72 h. In addition, the repellency effect was 91% for A. indica (class: V), 86% M. azedarach, 82%, N. tabacum (class: V), 79% N. rustica (class: IV), and 75% T. orientalis (class: IV) at 3% concentration against C. maculatus. Furthermore, following 96 hours’ exposure to treatment the sensitivity response of insects decreases as the time interval increases, i.e., 86% A. indica (class: V) was followed by 71% M. azedarach (class: IV), 65% N. tabacum (class: IV), 61% N. rustica (class: IV), and T. orientalis 57% (class: III) repellency at highest concentration of 3%. The current study concluded that A. indica and M. azedarach can be incorporated for the management of C. maculatus and these plant species might be helpful in the productions of new biopesticides.

“…It has been reported from Makkah in a previous study with potential antimicrobial activity (Alharbi et al, 2021). Other studies have reported the bioactive potential of the strain include the green synthesis of nanoparticles with antimicrobial activity (Sudarsan et al, 2021) and as a source of pigments (Hwang et al, 2022) and other high-value compounds for the management of diseases (Arun et al, 2022). Although larvicidal activity has not been reported previously for E. coli, the achievement of more than 70% mortality is significant for further investigation of the specific role of the organism in bioprospecting biocontrol agents.…”

“…Cytobacillus species is known to synthesize several compounds with antagonistic activity towards other organisms in the soil environment which gives it an advantage in outcompeting other organisms (Xu et al, 2022). The bioactive compounds produced by this organism have diverse roles including as a sustainable source of biopesticide and is one of the organisms recommended as a biocide due to the production of its bioactive compounds (Arakere et al, 2022) due to its nematicidal activity (D'errico et al, 2019) which makes the organism a potential biocontrol agent. It has been reported from Makkah in a previous study with potential antimicrobial activity (Alharbi et al, 2021).…”

Mosquito-borne diseases caused by infected mosquitoes like dengue fever, Zika fever, Chikungunya and malaria are spread to humans through biting causing disease epidemics all over the world. This indicates the necessity for new mosquito-borne disease control strategies in Saudi Arabia and internationally. This study evaluated the potential of local bacteria isolated from the soil of the Rahat region of Makkah, Saudi Arabia for the biocontrol of Aedes aegypti larvae, a major agent for the transmission of dengue fever. Soil samples were collected from the Rahat region, Makkah for the isolation of bacteria. The bacteria were evaluated for larvicidal activity against the larvae of A. aegypti. The bacteria that show toxicity to the larvae were identified using morphological and molecular characteristics. Four different strains of the bacteria with a toxicity towards A. aegypti larvae were isolated and identified. Two of the isolates (Brevibacillus centrosporus N8 and Cytobacillus species N7) caused 100% mortality in 24 h while the other two isolates (Escherichia coli N3 and Escherichia coli N4) caused at least 70% mortality. The findings of this study revealed the larvicidal activity of soil bacteria from the Rahat region, Makkah and could be a potential candidate for the biocontrol of mosquito vectors.

“…The genus Lecanicillium is known for its entomopathogenic properties and infects a wide range of insects [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. Strains of Lecanicillium ( Verticillium ) lecanii Zimmermann are not only commercially available to control severe agricultural pests [ 36 ], but have also been shown to be effective against storage pests such as S. oryzae [ 37 ], S. zeamais [ 38 ], and the red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) [ 39 ].…”

There is ample evidence that entomopathogenic fungi can be used as alternative biological control agents for the management of insect pests in storage facilities. As the market demands more environmentally friendly methods and chemical insecticides become increasingly obsolete, more studies are being conducted to evaluate new strains of entomopathogenic fungi for their efficacy in storage facilities. In this context, we tested ten species of fungi isolated from soil, belonging to the genera Cladosporium, Condenascus, Lecanicillium, and Penicillium, for their long-term effects on economically important beetle species. Whole wheat was directly sprayed with a conidial suspension of 108 spores/Ml of each of the tested fungi and then adults of Sitophilus granarius, S. oryzae, S. zeamais, Rhyzopertha dominica, and Trogoderma granarium were placed on the sprayed medium to study the mortality effects. Significantly higher mortality than the control was observed in all treatments. The lowest LT50 (9.164 days) was observed in T. granarium infected with Penicillium goetzii. The isolate with the strongest results was L. dimorphum, which recorded remarkably low LT50 values in S. oryzae (~11 days), R. dominica (~12 days), T. granarium (~10 days), and S. granarius (~13 days). However, for S. zeamais, it was more than 16 days. Our results confirm the existing literature on the efficacy of EPF on storage beetles, suggest the possible virulence of wild untested strains, and also highlight the importance of EPF specificity.
