“…The toxicity recorded in this study support different previous studies represented toxicity on larvae and adults as well as on fertility of plant origin essential oils against M. domestica (Pavela, 2008;Morey and Khandagle, 2012;Singh and Kaur, 2016;Walia et al, 2017). A previous study using R. communis extract recorded LC50 value of 353.4 ppm after 72 h of exposure to the extract and reported that the extract contained the ribosome inactivating protein ricin (Alvarez Montes de Oca et al, 1996).…”

The housefly, Musca domestica L., is a cosmopolitan insect, associated with various diseases and is one of the species with the greatest ability to develop resistance to insecticides. The study designed to evaluate the larvicidal, pupicidal, adulticidal and ovicidal effect of lethal concentrations LC50 of R. communis and Z. officinalis essential oils against the housefly M. domestica L. The larvicidal mortality (LC50) values of R. communis and Z. officinalis essential oils against M. domestica were 349.40 ppm and 132.60 ppm, with mortality percentage 46.67±2.89 and 50.00±0.00, respectively. The LC50 doses showed pupation mortality percentage (31.21 and 46.67) and adult mortality percentage (36.90 and 63.33), respectively. As compared to control, the treated 2 nd larval instar with either R. communis or Z. officinalis essential oils showed significant decline in the fecundity of M. domestica females through significant decrease in the total eggs number as compared to control (72.67% and 62.00%) with Effective Repellency (ER%) (51.34 and 58.48) and the Oviposition Activity (OAI) (-0.35 and -0.41), respectively. The hatchability of eggs recorded significant reduction as compared to control (86.38% and 73.66%) for R. communis and Z. officinalis, respectively. The present study revealed toxic properties of the tested plant extracts of R. communis and Z. officinalis against M. domestica L. and pave the way for its use as a measure of the eco-friendly housefly control.

“…The potentially disastrous consequences of synthetic chemicals on the global population and the environment have motivated the search for less toxic and more environmentally friendly alternatives. This has seen a renewed interest toward natural products and especially essential oils (EOs) for their antibacterial, antifungal, antiviral, antioxidant, anti-inflammatory, and insecticidal activity [6][7][8][9].…”

The extensive and sometimes unregulated use of synthetic chemicals, such as drugs, preservatives, and pesticides, is posing big threats to global health, the environment, and food security. This has stimulated the research of new strategies to deal with bacterial infections in animals and humans and to eradicate pests. Plant extracts, particularly essential oils, have recently emerged as valid alternatives to synthetic drugs, due to their properties which include antibacterial, antifungal, anti-inflammatory, antioxidant, and insecticidal activity. This review discusses the current research on the use of electrospinning to encapsulate essential oils into polymeric nanofibres and achieve controlled release of these bioactive compounds, while protecting them from degradation. The works here analysed demonstrate that the electrospinning process is an effective strategy to preserve the properties of essential oils and create bioactive membranes for biomedical, pharmaceutical, and food packaging applications.

“…In principle, PIPs, also termed semi-chemical pesticides, are also widely used for pest control. This is due to the minimal impact these class of biopesticides exert on humans and the environment [26,27]. Consequently, significant research and scientific resources are dedicated to PIPs as natural pest control agents.…”

“…Over the years, the adverse effects resulting from excessive utilization of synthetic chemicals have become widely reported [31]. Numerous studies have highlighted the toxic and persistent effects of pesticide residues on crop and food contamination along with soil and groundwater pollution [16,27,30]. In view of the above, there have been increased calls to discontinue the use of synthetic chemical pesticides in agriculture.…”

Abstract. The toxicity, persistence, and non-biodegradability of chemical pesticides have increased calls for the adoption of sustainable and cost-effective pest control measures. Biopesticides present a sustainable alternative to synthetic pesticides. However, the biopesticide utilization in agrarian countries like Nigeria remains low, resulting in increased chemical pesticide utilization. Therefore, this paper seeks to examine the current status, challenges, and prospects of biopesticides in Nigeria. The findings revealed that biopesticide utilization in Nigeria is low due to high costs, poor infrastructure, skilled manpower alongside inconsistent field performance and government policies. The solution to these challenges will significantly boost crop protection, food security, and sustainable agriculture in Nigeria.
