Climate change changes the new mechanism of the relationship between pests and natural enemies

According to researcher Ma Chunsen, current climate change biology mostly studies the impact of average temperature rise on organisms and their relationships
.

The natural climate change presents a significant day-night asymmetry, and the temperature increase at night is significantly higher than that during the day.

Ma Chunsen introduced that the current climate change biology mostly studies the impact of average temperature rise on organisms and their relationships

Therefore, night warming affects the population dynamics of natural enemies themselves and their predation on pests, and determines the pest-natural enemy interspecies relationship under climate change
.

The new findings of this study emphasize the importance of studying the population dynamics of pests and natural enemies under natural temperature fluctuations, and the effectiveness of natural enemies in controlling pests

In recent years, Ma Chunsen’s team has conducted systematic studies on the effects of night warming on pests, natural enemies, and their interactions.
The relevant results have been published in Functional Ecology, Journal of Animal Ecology, Biology Open, etc.
, clarifying the effects of climate change on pests and their natural enemies.
The mechanism of action will play an important role in furthering the research on the dynamic prediction of pest populations under climate change and the control function of natural enemies on pests
