Don’t kill wasps -- they’re just as important as bees, scientists warn. Wasps are being wiped out as quickly as bees – and their disappearance will be just as disastrous, according to new research. But the plight of wasps is going under the radar compared to that of their close cousins – because of their unpopularity. A lack of understanding of their vital role in the ecosystem and economy is a fundamental reason why they are hated – whereas bees are much loved.
Study author Dr Seirian Sumner, an environmental scientist at University College London (UCL), explained: "It’s clear we have a very different emotional connection to wasps than to bees. We have lived in harmony with bees for a very long time, domesticating some species.
"But human-wasp interactions are often unpleasant as they ruin picnics and nest in our homes. Despite this, we need to actively overhaul the negative image of wasps to protect the ecological benefits they bring to our planet. They are facing a similar decline to bees and that is something the world can’t afford."
The study, published in the journal Ecological Entomology, says both bees and wasps are two of humanity’s most important organisms. They both pollinate our flowers and crops – but wasps also destroy pests and insects that carry human diseases.
An insect "armageddon’ is under way due to pollution, habitat changes, overuse of pesticides and global warming [and Donald Trump!]. And they are vital to the make up of the countryside.
The international team also found wasps are an unpopular choice of insect for researchers to study which likely compounds their negative image.
Dr Sumner said our dislike of wasps is largely shaped by a small number of social species, the yellowjackets and hornets. These represent fewer than one per cent of stinging wasps but are most likely to come into contact with humans.
There are 67 social species but the vast majority of wasps, more than 75,000 varieties, are solitary. The bothersome nature of social wasps fuels the idea they are more dangerous than bees, although each elicit a similarly painful sting.
The research was funded by the Natural Environment Research Council and the European Commission through the Marie Curie fellowship.
