Insects in the world are experiencing fertility problems and heat waves caused by climate change are being accused.

A new study revealed that exposure to heat waves damaged and eroded male insects' sperm. This adds to the growing list of adverse impacts of climate change on biodiversity.

How Climate Change Reduces Insect Population

"We know biodiversity will suffer in climate change, but specific causes and sensitivities are difficult to reduce," said Matt Gage, leader of the research group at East Anglia University. ”In this study, we have shown that sperm function is a particularly sensitive feature in a model system that represents a large amount of global biodiversity when the environment is heated.“

The study used red flour beetle and exposed them to standard control conditions or heat wave temperatures. Then, the researchers evaluated how heat waves affect the reproductive success of insects, including sperm function and fry quality.

After exposure to heat waves, male insects found that sperm production decreased by three quarters. Furthermore, the male found that sperm from insects were trying to enter the path of female insects. This means that it is more likely that the sperm will not survive to fertilize the egg.

In addition, the study also revealed that exposure to heat waves contributes to less matching of male insects and potential decline in species population.

Researchers have used insects as a test subject because there are about 400,000 insect species around the world. Insects constitute 25 percent of all known animal species.

The Effects of Heatwave Exposure

Perhaps more concerned, exposure to heatwaves has a permanent effect on the life and reproductive activities of the outbreaks of insects. The sons of male insects exposed to heat waves for experiment experienced a few months shorter than the average. They also fertilized much less female insects and produced significantly fewer products than themselves.

Climate change is suspected of providing the collapse of insect biodiversity in the world, but it still remains unclear how it affects biodiversity. Researchers hope that more work is needed to see if climate change is a factor in the mass regression of insect populations worldwide.

The study was published in the journal Nature Communication.
