Cuckoo spit/spittlebug foam on vegetation is innocent. Please depart it alone.


    I’m often delighted to see Eire’s Wildlife featured within the media — however a current article printed within the Gardening part of the RSVP Journal web site has me lower than thrilled.

    The article in query sensationalises the connection between frog-hoppers/spittle bugs (their American identify) and a bacterial plant illness referred to as Xylella fastidiosa. Sure, in areas the place Xylella happens, sap-sucking bugs like frog-hoppers usually change into vectors by way of which the pathogen spreads to different close by vegetation, nevertheless, Xylella is NOT CAUSED by the insect, and the frothy spittle so widespread on vegetation all through the Irish countryside in early summer time IS NOT an indication of illness. In actual fact, it’s a completely regular a part of a wholesome Irish ecosystem.

    Now we have by no means had a confirmed circumstances of Xyllela right here in Eire, and so they have recorded none to this point within the UK both. For now at the least, it merely doesn’t happen right here.

    The RSVP Journal article latches on to a reputable name for data from scientist within the UK, and twists it into one thing altogether extra sinister. All of the scientists are asking for is for the general public to submit data of cuckoo spit and grownup frog-hoppers, serving to them to map their distribution. That information will assist them make extra knowledgeable choices on how greatest to reply IF Xylella ever does arrive.

    Simply to be 100% clear right here: these scientists are not suggesting cuckoo spit is in any approach dangerous, they’re not calling for anybody to manage frog hoppers or eradicate cuckoo spit of their gardens or anyplace else. They’re simply gathering information to raised perceive their distribution.

    To summarise:

    • Xylella fastidiosa has by no means been recorded in Eire
    • Frog Hoppers / Spittle Bugs are widespread, widespread native Irish bugs
    • They DO NOT trigger illness in vegetation (though the place Xylella is current they’ll unfold it)

In case you’re serious about discovering out extra concerning the state of affairs surrounding Xylella, right here’s a complete overview of Xylella and frog-hoppers within the UK that’s nicely offered and fact-based.

    The hazards of poor reporting in a Biodiversity Disaster

    No one is denying that Xylella is a critical illness, and has induced devastation in elements of mainland Europe (notably to Italian olive groves). Measures to manage and limit the unfold of the micro organism that causes the illness are fully warranted. What’s unwarranted is equivocal reporting that misrepresents the details, casting a innocent constituent of our native biodiversity because the villain in a contrived and appallingly inaccurate narrative.

    Wildlife isn’t any stranger to being forged because the scapegoat for human-induced issues within the pure world, however amidst a biodiversity disaster, articles just like the RSVP one, that sensationalise threat, foster suspicion and demonise a local species, will be extremely damaging. We’ve been receiving emails and messages since this text went out from individuals asking how they’ll eradicate cuckoo spit from their backyard vegetation.

    The reply, in fact, is you don’t have to do something. Because the BBC Gardener’s World web site advises “It’s greatest to depart the froghoppers to get on with being froghoppers.”
