    Default Preventing maggots in plums

    I like to get my pheromone traps for fruit moths out a bit early than usually recommended. Partly because of not wanting to forget, but also because I find that the weather has the biggest impact on what I catch regardless of the exact flowering dates. So warm still nights now the plums are in bloom are usually when I get most moths.

    BTW being mean and as the refills are much cheaper than the whole caboodle is, I made a metal roofed tray thingy to put the sticky-card traps in, which I can re-use every year.

    PS just to add this is not a complete eradication system - it does reduce the numbers, but the professionals boys use these traps to help time their sprays with which they can get almost 100% control.

    Thanks for the heads up Nickbud. This will hopefully be the first year of fruit on my oldest plum. Would one expect low numbers in the first year if no other plum trees nearby ? If not what make of refill do you find the most effective please?

    Quite honestly, if your plum hasn't cropped recently, and there aren't any others nearby, I wouldn't bother with the traps. Not everyone will get these pests and they take several years to build up to nuisance numbers. ( The moths you catch are the males, and they don't fly at all well and I think the females are either flightless or very nearly so.)

    You'll soon know if they move in to be a bother BTW, as when you start on the plum you'll find an unwelcome pink grub eating away from the inside - usually near the stone.

    I think I've only seen one manufacture of the plum moth pheromone traps - you can get them sometimes at garden centers, but from memory I think I bought my last set of refills off Amazon (I'm not at all keen on going out shopping)

    Thanks Nickdub, that was the answer I was hoping for as being kept busy with vine weevil. However will mark calendar for next year

    Had a look in my trap today and have around 10 moths so far - a lot less than I have had in previous years, but now the warmer weather is here the total may go up rapidly.

    Just a reminder for people this year to order a refill of the Plum Moth pheromone lure if you had problems last year - obviously been a lot warmer this year, so the blossom here will be out in a few weeks.

    Put my new pheromone trap lure out today (inclined to forget if I leave it ) and was surprised to find that the old lure had caught a couple of new moths (I just replace the lure, not the sticky sheet) - just goes to show that my policy of doing nothing much (ie being lazy) sometimes has a positive side to it.

    The new lure was about 5, but I reckon its worth it if it keeps the moth numbers from getting worse.
