Insects. Phenological observations
Determining the timing of the insects development phases is critical for the insect pest control. Long-term observations of insects allow to determine the average long-term dates of their appearance and to associate them with the onset of a number of other natural phenomena. The period of insect development from an egg to a sexually mature state is called the life cycle, or generation.
Different insects species have different rate of development. Some have one generation within one year, others have two and more. Insects’ life cycle developed historically in the process of their evolution in a certain geographical environment. It may be the same throughout the distribution of the species and may vary depending on geographical conditions.
On the territory of Yakutia, three successive seasonal aspects can be distinguished for insects
The early summer aspect is observed from the 3rd decade of May to the first decade of July.
The summer aspect from the 2nd decade of July to the end of the first decade of August is the time of insects abundance in species.
The late summer aspect is the least pronounced and manifests itself from the 2nd decade of August to mid-September.
