“…For many of the species, an exaggerated and extrapolated data is available without a proper trend to conclude anything about decline. Further the robust data collected from risk areas habituating various species is especially insufficient to assess any trend especially from arctic and tropical regions of world, for example southern hemisphere [35].…”

There are lot of reasons and causes of insect decline. The main causes of insect decline is attributed to habitat destruction, land use changes, deforestation, intensive agriculture, urbanization, pollution, climate change, introduction of invasive insect species, application of pesticides, mass trapping of insects using pheromones and light traps, pathological problems on various insects, and introduction of exotic honey bees in new areas that compete with the native bees for resource portioning and other management techniques for pest management, and even not leaving any pest residue for predators and parasitoids for their survival. The use of chemical insecticides against target or non-target organisms is major cause for insect decline. The diseases and decline of the important pollinators is still a mistry for colony collapse disorder. To overcome the cause of insect decline, various conservation techniques to be adopted and augmentation of artificial nesting and feeding structures, use of green pesticides, maintaining the proper pest defender ratio (P:D), policies and reaching to political audience at global level and other factors already discussed in the chapter may be helpful for mitigating the insect decline and especially for the pollinators, a key insect for life.

“…Living organisms are very sensitive to changes in their environment and react also to the presence or change of the electromagnetic eld. Several authors have studied the impact of EMF on different types of organisms ranging from bacteria to invertebrates to vertebrates [4][5][6][7][8][9][10][11] . Currently, it is a known fact that mobile phones affect living organisms 6 .…”

“…A major eld study on insect pollinators had evidence that electromagnetic smog may have important ecological and economic impacts on the pollination service that could signi cantly affect the maintenance of wild plant diversity, crop production and human welfare 14 . Balmori 4 proved that EMF has a signi cant effect on reducing the number of insects (pollinators) in nature. Together with climate change, invasive species, and other factors, this can lead to signi cant changes in agriculture 4 .…”

Mobile telecommunications technologies have become an indispensable part of people´s lives of all ages around the world. They affect personal life and social interactions and are a work tool in the work routine. The requirements for network availability and the quality of the Internet connection are constantly increasing, to which telecommunications providers are responding. Humans and wildlife live in an environment with the permanent presence of electromagnetic radiation with just a minor knowledge on the impact this radiation has. The aim of our study was to investigate the effect of 900 MHz electromagnetic field (EMF) on the exploratory behavior of female Ixodes ricinus ticks under laboratory conditions. Experiments were realized in the radiation-shielded tube (RST) test radiation-shielded circular open field arena, altogether 480 female I. ricinus ticks were tested. While in the RST arena we observed only a tendency to move towards the irradiated part of the arena, in the open field arena the time spent in the part exposed to EMF and the trajectory passed was significantly longer.

“…This equilibrium is daily at risk as workers patrol an environment highly modified and full of anthropogenic pollutants, especially in more developed countries. Therefore, poor nutrition and starvation [1][2][3], diseases [4,5], mites [6,7], habitat losses and fragmentation [1,8], contamination by pesticides and other pollutants [9], electromagnetic fields [10][11][12] and general environmental stresses including climate change [6,13] have been indicated as possible causes of the general bee decline and of the phenomenon called colony collapse disorder (CCD) [14][15][16][17][18].…”

Honeybee and general pollinator decline is extensively reported in many countries, adding new concern to the general biodiversity loss. Many studies were addressed to assess the causes of pollinator decline, concluding that in most cases multi-stress effects were the most probable ones. In this research, the combined effects of two possible stress sources for bees, pesticides and electromagnetic fields (multi-stress conditions), were analyzed in the field. Three experimental sites were chosen: a control one far from direct anthropogenic stress sources, a pesticide-stress site and multi-stress one, adding to the same exposure to pesticides the presence of an electromagnetic field, coming from a high-voltage electric line. Experimental apiaries were monitored weekly for one year (from April 2017 to April 2018) by means of colony survival, queen activity, storage and brood amount, parasites and pathogens, and several biomarkers in young workers and pupae. Both exposure and effect biomarkers were analysed: among the first, acetylcholinesterase (AChE), catalase (CAT), glutathione S-transferase (GST) and alkaline phosphatase (ALP) and Reactive Oxygen Species (ROS); and among the last, DNA fragmentation (DNAFRAGM) and lipid peroxidation (LPO). Results showed that bee health conditions were the worst in the multi-stress site with only one colony alive out of the four ones present at the beginning. In this site, a complex picture of adverse effects was observed, such as disease appearance (American foulbrood), higher mortality in the underbaskets (common to pesticide-stress site), behavioral alterations (queen changes, excess of honey storage) and biochemical anomalies (higher ALP activity at the end of the season). The overall results clearly indicate that the multi-stress conditions were able to induce biochemical, physiological and behavioral alterations which severely threatened bee colony survival.
