Pests and Diseases> Light Brown Apple Moth


The Light Brown Apple Moth are native to Australia. The larvae feed on a wide range of plants and is a well-known fruit fruit crop pest that may be on your seedlings. The catarpillars are pests of a wide variety of horticultural plants, fruits, deciduous trees and garden shrubs in many parts of the world. LBAM has been recorded from over 2000 different types of plants encompassing 50 plant families.
You may only find it on one or two seedlings, but it's important to identify and remove to prevent further damage to your plants and before being transerred to the countryside where it can significantly damage crops.

If LBAM are using your seedlings as host plants, you'll see it as eggs, larvae or catarpillar.

Signs of LBAM on your seedlings

The eggs: The moth will web leaves together, or fold a single leaf to lay it's eggs. Young eggs appear as pale blue-green, scale-like masses of 10-60 eggs on leaves or stems. Prior to hatching, the heads of caterpillars will give the mass a dark and blotchy appearance. 
Eggs are laid in masses on the upper surface of smmoth-leaved plants. The eggs take from 5 to more than 30 days to hatch, dependinding on the temperature.





The caterpillar(larvae): Indications of the caterpillars presenceare leafs rolls and leaves wrapped together. Caterpillars vary from 1mm to 1.5cm in length, depending on their stage of development. The young larvae prefer to feed on the underside of leaves and they spin a fine webbing as a protective cover. As the larvae mature they feed between two leaves webbed together. Youll find them in most seedlings, occuring more in those with broad leaves. The newly emerging (larvae) catarpillars are very tiny with a pale yellow-green body and a pale brown head. The adult caterpillars are pale green with a dark green central stripe.



Skeletonised leaves are also a sign of the moth on your seedling.

If you see this lacing on your leavs you know that the LBAM larvae is somewhere in your seedlings. Look at everything very closely. Check every curled or oddly bent leaf. We do not to sent out this dreadful menace with our  seedlings out to the country side

Removing LBAM

Integrated pest consultant Jenny Chivers suggests picking affected leavesfrom the seedling with one hand under the leaf to catch any dropping larvae. Sqish larvae with thumb and forefinger so they cannot do further damage to seedlings.

"It may seem tedious but it will be successful. The important thing is to keep regularly checking," she advises.
