Insects Change Behaviour with Change in Weather

Insects are known to be the most profuse animal group on the whole planet. The species is also known by scientists as the most diverse.

A recent study has claimed that while sex could be thrilling, the sense of possible storms prevent bugs from doing the same. Not only this, but varied other behaviours of insects are changed before the arrival of storms.

Nevertheless, the tiny creatures still remain at risk from the powerful winds or heavy rainfall during the storms. It is being asserted that the same scenarios could mean the end of insects' lives.

The research had been carried out by Jeremy McNeil and colleagues from the University of Western Ontario in Canada. They said that insects were found to be transforming their emission techniques and response to pheromones.

As per the findings, pheromones are scents associated with sex. The insects changed their reaction to these according to the climate. Mating behaviour of three bugs, including the true armyworm moth, the cucurbit beetle and the potato aphid, was examined.

The team concluded that a fall in atmospheric pressure due to weather caused male insects to get less attracted to female pheromone sources.

"As the globe proceeds to warm, these findings suggest climate change might change the behavior of insects as well - not only of pests, but also of beneficial insects", McNeil was quoted as affirming.
