What Is Insect Ecology?

Insect ecology is a discipline that uses the theoretical knowledge and methods of experiments, physics, chemistry, mathematics, geography, genetics, behavioral ecology and other basic and applied disciplines to study the interaction between insect life phenomena and the surrounding environment. Including: insect individual ecology, insect population ecology, insect community ecology. According to the time, season, and insect period of insects appearing on human corpses, analyze and judge the interval and cause of death after death, and provide scientific theoretical basis for case detection. The suitable temperature for the development of fly larvae is 16 ~ 35 ° C. The development time is: housefly needs 3 ~ 6 days, housefly 12 days, body fly 10 ~ 17 days, toilet fly 9 days, flies 10 ~ 12 days, pupae Flies for 6 to 20 days. (Hou Yuying) ^[1]

The content of insect ecology research can be divided into:

1,

Due to the mutual penetration of insect ecology and other disciplines, the theories and methods of other basic and applied disciplines have been used to study insect ecology, and many branch disciplines have been formed, generally including experimental ecology of insects, insect physical ecology Physical ecology of insects, chemical ecology of insects, mathematical ecology of insects, geographi cecology of insects, genetic ecology of insects ), Paleoecology of insects, comparative ecology of insects, behavior ecology of insects, economical ecology of insects, etc.

The various eco-environmental factors that constitute the overall environmental conditions of insects can be divided into two categories according to their nature. One is abiotic factors, that is, climatic factors, or inorganic factors, mainly including temperature, humidity, precipitation, light and wind. Wait. The other is biological factors, that is, organic factors, mainly including insect food and natural enemies. The so-called soil factor is a comprehensive factor that includes both abiotic factors (such as soil temperature, humidity, physical and chemical properties, etc.) and biological factors (such as soil microorganisms, animals, and plants). Human factors mainly refer to the impact of humans on insects in production practices.

The main tasks of insect ecology are to study the adaptability and variation of insects to different ecological environments, analyze the intra- and inter-species relationships of insects and their behavioral mechanisms that respond to environmental conditions, and study insect populations in different regions, environments, and time and space. Quantitative dynamics, the status and role of insects in communities and ecosystems, and the status of insect survival and changes after changing the natural environment, etc., for environmental protection, conservation and utilization of resources and insects, insect flora, and integrated pest management And forecasting provide theoretical basis.
