Influence of abiotic environmental factors on forest insects,Light rays of different wavelengths exercise various direct or indirect influences on insects. Besides visible radiation (0.4 < λ Ⓧ 0.7 μm), provide heat and thus increase body temperature, as well as ultraviolet rays of 0.4-0.003 ύm wavelength, which may have important chemical, and consequently biological, effects on living protoplasm.

Causes and course of changes in the abundance of insect,e causes and course of changes in the abundance of populations have undergone many developments during the recent decades. Studies have gradually been extended to cover the ever-increasing numbers of new species and a knowledge of their geographical and ecological systems has been made possible by the refinement of modern techniques.
