“…Most Auchenorrhyncha species feed on plant sap, so they directly absorb the heavy metals found in plant sap. Cadmiun (Cd), zinc (Zn), copper (Cu), arsenic (As), Fe, mercury (Hg) and lead (Pb) are usually reported in superworms, yellow mealworms, termites, locusts, black soldier fly larvae and grasshoppers (Malematja et al, 2023). In some previous studies conducted with grasshoppers, heavy metals such as Pb and Cd were found in insect bodies (Handley et al, 2007;Zhang et al, 2009;Poma et al, 2017).…”

“…It was reported that Cu concentration in worker termites found in southwestern Nigeria was 0.076 mg/L (Idowu et al, 2019), in termites collected from natural habitats was 0.08-0.18 mg/L (Kapaale et al, 2021) and in housefly larvae was 9.06 mg/kg (Gao et al, 2019). The accumulation of heavy metals in insects varies depending on the pollution status in the habitat, insect species and heavy metal type (Ng'ang'a et al, 2021;Malematja et al, 2023).…”

Traffic is an important pollution factor causing environmental damages such as soil, water and atmospheric pollution, greenhouse effect, and climate change. Effects of traffic pollution on various organisms enlightened with various studies. In this study, it was aimed to examine the effects of traffic-based pollution on Auchenorrhyncha (Insecta: Hemiptera) species in apple orchards and their potential as biomonitor for heavy metal pollution. The Auchenorrhyncha specimens were collected from the apple orchards near the Amasya-Samsun motorway in Türkiye. The heavy metal concentrations were determined by ICP-OES. Five Auchenorrhyncha species were determined from three sites from each of three different distance. Empoasca decipiens specimens were collected only from 0 m while others found in all localities. Heavy metal concentrations in insect specimens tended to decrease with the increasing distance from the motorway. These differences were clearly indicated in Psammotettix provincialis and Phlepsius intricatus, which were found in all localities. Except for Ni, Fe and Mn for Phlepsius intricatus, all examined heavy metals significantly varied in both species. Results showed that heavy metals tended to accumulate in the body of Auchenorrhyncha specimens and because of this they may be evaluated as a biomonitor for heavy metal pollution.

“…The available evidence suggests that insects are generally safe and offer beneficial or neutral outcomes compared with other foods [ 162 ]. However, some insects may produce or contain toxic bioactive compounds, and there is potential for contamination with pesticides and heavy metals from the environment [ 163 , 164 , 165 ]. Additionally, allergic reactions to edible insects could pose a hazard in some individuals [ 166 , 167 ].…”

The present review highlights the potential of insect-based proteins to address the growing need for sustainable and secure food systems. The key findings suggest that edible insects offer a viable and environmentally friendly alternative to traditional livestock, requiring significantly less land, water, and feed while emitting lower levels of greenhouse gases. Insect farming can also reduce waste and recycle nutrients, supporting circular economy models. Nutritionally, insects provide high-quality protein, essential amino acids, and beneficial fats, making them valuable to human diets. Despite these benefits, this review emphasizes the need for comprehensive regulatory frameworks to ensure food safety, manage potential allergenicity, and mitigate contamination risks from pathogens and environmental toxins. Additionally, developing innovative processing technologies can enhance the palatability and marketability of insect-based products, promoting consumer acceptance. This review concludes that with appropriate regulatory support and technological advancements, insect-based proteins have the potential to significantly contribute to global food security and sustainability efforts.

“…Edible insects have the potential to play a significant role in the bioconversion of agri-food wastes, which have a vast global production estimated at 1.3 billion tons per year (Żuk-Gołaszewska et al, 2022). Numerous studies indicate that the accumulation of pesticides and heavy metals in insects is mainly associated with agricultural waste materials fed to insects (Houbraken et al, 2016;Malematja et al, 2023). Pesticides used on plants could build up over the lifespan of insects that feed on waste materials, potentially posing a health hazard to humans who consume those insects.…”

For several years, the concept of consuming insects has been attracting significant interest in Europe, given its potential to provide an environmentally sustainable, meat-alternative source of protein in the diet, not only for animals but also for humans. In Poland at the beginning of 2023, there was a considerable interest around edible insects, but in a negative context. A disinformation campaign was conducted on television and social media, claiming that edible insects threaten human health. It was suggested that consuming insects is a futuristic fad, an ideological madness, a concept conflicting with Polish economic interests, particularly affecting farming areas. This work aimed to present the most important, reliable data regarding edible insects to create a comprehensive and objective informational foundation. This foundation can serve as a basis for making decisions regarding the potential utilisation of insects as a food source.
