Scientists at the University of Guelph and University of Waterloo Ontario suggests that a warming climate implies more houseflies.This study was published in the Royal Society Open Science on 13 February 2019.
Climate change is the most talked about topic from the past couple of years. Change in weather impacts everyone at a level which is a cause of concern.
Weather change has an impact even on insects. It is said that within the next few decades the population of insects could go extinct. Change in environmental conditions is one of the major reasons behind it.
On the contrary, a study says that in the process of changing climate especially in warmer weathers, the activity of houseflies tends to increase.
Amy Greer, a mathematical modeler and one of the authors of the study says, “Under a warming scenario you'd have a larger fly population which is able to hang around for a longer period of time.”
It is believed that houseflies do better in a warmer, hotter world. The flies are more active when the climate is warm. With the increase in fly activity, there is a possibility of an increase in the transmission of Campylobacter.
Campylobacter is a bacterial infection that causes gastroenteritis in humans. It is one of the main reason for food poisoning.
Melanie Cousins, one of the authors of the study, modeled and observed bacterial and insect trends under different weather warming conditions. The results indicated that the increase in the number of fly population was not of much importance.
But if the warming temperature continues to increase, there is a possibility that Campylobacter incidents could more than double by the year 2080 due to an increase in fly activity.
It is to be noted that the scientists did not test the flies landing on food, to check if they were leaving bacteria. However, previous studies signify that flies may carry Campylobacter but there is no evidence stating that with the warming of climate their ability to do so will increase.
The National Center for Biotechnology Information also conducted a study on flies in relation to Campylobacter. They also derived a hypothesis with the threads of evidence they found. They discovered that flies may appear to carry Campylobacter.
This study is based on a number of assumptions and is a hypothesis with no incidents to prove the study as the results were done on a mathematical model. Still, scientists are taking it into consideration and working on further related studies.
