Neonicotinoids: History, Impacts, Sustainable Use, and Application Scenario

The neonicotinoid group of insecticides, known for their broad-spectrum effectiveness, are extensively utilized globally due to their well-established benefits in terms of their mode of action. Consequently, their utilization is expanding extensively and, furthermore, is frequently employed as a preventive measure without taking into account the ecological consequences. Research has shown that non-target creatures are adversely affected, leading to a negative impact on biodiversity and, consequently, food production. Neonicotinoids are effective in controlling pests, but concerns have arisen about their potential impact on the environment, especially on bee populations and other pollinators such as birds and bats, which play a crucial role in plant pollination. Some of these effects include impairments in bee navigation abilities, reduced foraging capabilities, and decreased bee colony productivity. The policy of sustainable use of neonicotinoids, a group of insecticides widely employed in agriculture, is currently the subject of intense debate and scientific research. Scientific research should be the primary focus for seeking ecologically viable answers to these problems. In light of these issues, numerous nations have implemented regulations or prohibitions on the utilization of neonicotinoids, especially in crops that attract bees and other pollinating insects. However, the policy regarding the use of neonicotinoids must take into account both the protection of pollinators and the needs of farmers who may require effective methods to protect plants from pests. There is a concern over whether the global research activities fulfill these requirements worldwide. Hence, the objective of this chapter was to examine the worldwide research scenario on neonicotinoids from ecological, economic, and temporal perspectives. In order to achieve this objective, the main participants and motivations for inquiries in this particular area of research are recognized. The progressive rise in publications over time is substantial and demonstrates a dynamic pattern of citation. There is a noticeable and increasing interest in contemporary research, particularly in ecological challenges, which are becoming the main focus of international study. Evidence demonstrates that the publication performance and funding of nations align with the interests of the global market, with China emerging as the leading country in terms of publishing. Furthermore, the high level of scientific infrastructure in economically advanced countries and their commitment to funding research can be associated with the national output of research. Less developed economies have limited participation in published studies. The research performance exhibits a significant disparity between the North and South regions. Hence, forthcoming research endeavors should prioritize sustainability and consider global regional needs. Developing countries must play a more significant role in addressing this issue, as they are the regions that are most economically reliant and experiencing significant increases in consumption. Efforts must be made to address the issue of sustainable food production in the face of decreased biodiversity caused by the widespread use of neonicotinoids. Additionally, it is vital to conduct additional investigation on the impact of neonicotinoids on the environment and to search for alternative plant protection methods that will be less harmful to pollinators and other organisms.
