Plutella xylostella
The diamondback moth is a damaging pest of canola and brassicaceous crops in Australia. Diamondback moth larvae are pale yellowish-green, slightly tapered at each end and approximately 10 mm long when mature. The moths are about 10mm long and are grey-brown in colour. They have a characteristic whitish strip of uneven width down the back, which resembles diamond patterns. Reliance on chemicals as a control measure for the diamondback moth has resulted in the development of resistance to many insecticides.
