Influence of Seasonal Variations on Insect Population Dynamics in Agro-Ecosystems

Abstract

Seasonality contributes significantly to the population of insects in agro- ecosystems, which defines the amount of pests, pollination, and ecosystem functionality. The temperature humidity precipitation photoperiod interaction facilitates the regulation of reproduction, development and migration of insects hence dictating population structure and species composition. This study assesses the effect of seasonal variation on the insect diversity, abundance and distribution over time in agricultural landscapes and the research implications to crop production and pest management methods. Long-term monitoring and ecological models as well as observational studies have synthesized information that has put forward that predictability of insect populations is tendentious with species abundance skyrocketing within good environmental conditions. Furthermore, the abnormal seasonality, e.g. long-term droughts or untimely precipitation, can disrupt the population dynamics, altering the interdependence between predators and prey and pollination. The findings reveal the importance of considering the seasonality role in agro-ecosystem management tools to enhance crop protection and the maintenance of a positive population of beneficial insects as well as the attainment of sustainable agriculture.
