Pome Fruits

Codling moth is the most damaging pest of apple, pear, quince and nashi crops in Australia, being endemic to all Australian States and Territories except Western Australia and the Northern Territory. Codling moths also affect walnuts and Japanese plums. 

The larvae are internal feeders of the fruit and can decimate crops if not controlled, with one per cent of fruit with damage symptoms being the generally accepted threshold. Varieties that are harvested late in the season, such as Pink Lady are most at risk due to being exposed to the pest for longer periods. 

Light brown apple moth (LBAM) is native to Australia and is a significant pest to many introduced crops, including, apples, citrus, grapes, apricots and pears. Light brown apple moths are present in all pome fruit growing regions of Australia. Damage is often worse in seasons where cool conditions extend into summer and conditions favour the growth of host plants. In some countries, including the USA, it is considered a quarantine pest and therefore its presence can threaten export markets.

Powdery mildew affects grapes and apples and is one of the most widespread, persistent and damaging fungal diseases in both Australian vineyards and apple orchards.
