Abstract The Baluchistan Melon Fly (Myiopardalis pardalina (Bigot, 1891) (Diptera: Tephritidae)) is a highly invasive pest. It poses a serious threat to global cucurbit production, destroying more than 90% of the crop during outbreaks. The Baluchistan Melon Fly has a four-stage life cycle (egg, larva, pupa and adult) and has distinct morphological adaptations. The species’ geographic range continues to expand, driven by global trade networks and its adaptation to changing climatic conditions. Infestations of this pest severely reduce yields, undermine food security and destabilize rural economies dependent on cucurbit cultivation. A variety of control strategies are evaluated, including surveillance and quarantine methods, agronomic practices, physical controls, chemical management, biological agents, and emerging genetic tools. It emphasizes the need to adopt integrated pest management (IPM) to strike a strategic balance between effectiveness, ecological sustainability, and operational scalability. Conventional insecticides are often ineffective against its internal feeding larvae, highlighting the need for innovative and integrated management strategies. Protecting cucurbit crops from the Balochistan melon fly is not only an agricultural priority, but also a critical step in protecting rural economies and global food security.

Abstract Air pollution is one of the major environmental stresses of the modern era whose impacts extend beyond human health and also affect the sustainability of agricultural production and food security. Pollutants such as ozone (O₃), sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and particulate matter (PM2.5 and PM10) can increase plant susceptibility to pests and pathogens by inducing oxidative stress, disrupting photosynthesis, reducing nutrient uptake, and weakening plant defense mechanisms. In addition, air pollution can disrupt the ecological balance of agroecosystems by degrading or altering plant volatile organic compounds, thereby interfering with the activity of pollinators and natural enemies of pests.

Evidence from field studies in different countries indicates that severe air pollution is associated with reduced crop yields, increased pest pressure, and the intensification of certain plant diseases. For example, a field study reported that exposure of plants to pollutants from diesel exhaust and ozone reduced pollinator abundance by about 62–70% and flower visitation by approximately 83–90%, leading to a decline in plant reproductive success. Pollutants may also reduce the capacity of plants to cope with biotic stresses by decreasing soil biological activity and disrupting nutrient cycling.

This article adopts a scientific–extension perspective to examine the direct and indirect pathways through which air pollution affects plants, pests, plant diseases, pollinators, natural enemies, and soil health, and highlights that air quality is an important yet often overlooked component of food security.

Abstract Azole compounds have become one of the most widely used pesticide groups worldwide due to their high efficacy in the management of fungal pests and diseases. The majority of these compounds, especially triazoles, act by targeting the demethylase enzyme and inhibiting the ergosterol biosynthesis pathway in the cell membrane of fungi. The range of applications of these compounds has expanded from the protection of agricultural and horticultural crops to the food industry and the treatment of fungal infections in medicine. Despite the key role of azoles in food security, their concentrated and repeated use has led to serious environmental challenges, including persistence in ecosystems and bioaccumulation in non-target aquatic and terrestrial species. However, due to their favorable efficacy and relatively lower toxicity indices compared to previous generations of pesticides, various derivatives of this family such as triazoles, pyrazoles, imidazoles and oxazoles are still approved and used as the main active ingredients in the formulation of plant protection products. This article, while reviewing the mechanism of action and applications of these compounds, analyzes the balance between agricultural efficiency and their ecological risks.

Abstract Postharvest fungal diseases are one of the fundamental challenges in the supply chain, storage and marketability of peach (Prunus persica) fruit. The presence of effective pathogens such as Monilinia spp., Penicillium expansum, Rhizopus stolonifera and Botrytis cinerea leads to extensive economic losses worldwide. Although the traditional management of these diseases is mainly based on the use of chemical fungicides, the emergence of pathogen resistance, public health concerns and regulatory restrictions have seriously challenged the effectiveness of these methods. The present article reviews and evaluates new control approaches including chemical, physical and biological methods, with a particular focus on the use of plant essential oils, microbial antagonists, induction of systemic resistance and environmentally friendly disinfectants. The findings indicate that integrated management is the most promising path to achieving sustainability. Finally, emphasis on a detailed understanding of the mechanisms of contamination and environmental conditions governing the epidemiology of each pathogen underlies the design of efficient control strategies tailored to the dynamics of the disease.
