About the book
Insects play an important role in the life of human beings through the pollination of the majority of plants around the globe. They provide humans with valuable products such as honey, silk, medicinal, and cosmetic materials. Insects keep the soil in a healthy condition through the improvement of aeration and recycling of nutrients. They also play an essential role in the food web of other animals. Insects represent about 73% of the total species of animals identified so far in the world. There is clear evidence, in recent years, indicating a noticeable decline in the number of global insects. Many studies have been carried out in different countries in the world documenting the disappearance of global insects at an alarming rate. A recent review published in the journal of biological conservation indicated that the decline is larger in insect number of terrestrial insects as compared with the aquatic insects. The reports on global insect declines presented that the main reasons behind this decline are agricultural intensification, climate change, excessive use of persistent insecticides, deforestation, and urbanization.
This book aims to give comprehensive information on the possible causes of global insect decline, the impact on human livelihood, ecosystem, and possible measures to stop or at least slow such rapid decline in the number of global insects. The book would be a valuable reference for ecologists, conservationists, and entomologists.
