It’s time to set pheromone traps.

NZ Gardener - - What To Show & Plant This Month ... -

Ap­ples, quince and pears are all likely to be bloom­ing and about to set fruit – which means codling moths will be emerg­ing from their over­win­ter­ing hidey-holes un­der the ground and on the wing look­ing to lay their eggs! So set pheromone traps now and start count­ing the dead male moths you catch. When you have caught about a dozen, it’s time to spray your trees with neem oil or a prod­uct to con­trol cater­pil­lars such as Yates Suc­cess Ul­tra In­sect Con­trol (if your trees are small enough you can also shake Yates Tomato Dust over the whole tree). The only time in its life cy­cle when the codling moth is vul­ner­a­ble is after the lar­vae has hatched but be­fore it has had a chance to bur­row into your fruit – when it pu­pates (goes from lar­vae to moth) it’s hid­den un­der the ground or in a cre­vice in the bark, and very soon after it hatches, the new lar­vae will bur­row into your de­vel­op­ing fruit and ruin your crop! It’s a com­mon mis­take to think that the pheromone traps are them­selves a con­trol, but they are not (un­less you rely on catch­ing all the male moths in your vicin­ity, so you have just vir­ginal – and there­fore harm­less – fe­male moths left, but I wouldn’t rec­om­mend that!). Us­ing pheromone trap just lets you time the ap­pli­ca­tion of a spray to give you the best chance of suc­cess. If you have chooks, let them roam around un­der your trees over spring too – they make short work of moths as they emerge from the ground. You can also help pre­vent the newly emerged moths tak­ing to the skies (and soon start­ing a fam­ily) by scat­ter­ing neem gran­ules around the base of any trees likely to be af­fected (which in­cludes all pip fruit and wal­nuts) ev­ery few weeks from the start of spring un­til Novem­ber or De­cem­ber.

Set your traps.
