The Department of Primary Industries and Regional Development continues to support the growth and international competitiveness of all crop industries in Western Australia.

With a 2400 kilometre span from its tropical north to its temperate south, WA supports a broad range of cropping industries from rain-fed winter cereals through to irrigated horticultural crops.

In the 2012/13 year the WA cropping industries exported a total of $3.9 billion which comprised: $3.1 billion of cereals, $859 million of pulses, pastures and oilseeds, $142 million of horticultural crops. The major contributors to these exports were wheat ($2.7 billion), canola ($756 million), barley ($377 million), lupins ($42 million), carrots at $48 million, oats ($12 million), and strawberries at $5.5 million.


  • Cabbage aphid

    Small soft-bodied winged (adults only) or wingless insects that damage canola by direct feeding or as a viral disease carrier.

  • Vegetable weevil

    Weevils are beetles with long snouts that can damage or kill young seedlings.

  • Cutworm moths

    Cutworm caterpillars feed on seedling leaves and stems near ground level with stems often chewed through and ‘cut’ to ground level.

  • Left to right: larva, pupa and newly emerged adult bronzed field beetle

    False wireworms that damage canola crops are the larval stage of the bronzed field beetle.

  • Shiny black insects with light brown legs and rear pincers (Male left, female right)

    A chewing insect introduced from Europe that can damage seedling crops and contaminate grain. Mainly found in the southern wheatbelt.

  •  Caterpillar up to 40 millimetres long usually with a dark streak along its body

    The native budworm caterpillar can cause serious yield loss to canola as pods mature.

  • Brown moth with yellow markings on the wings and orange rings around the body

    The caterpillar of the pasture day moth (Apina callisto) feeds on broadleaf weeds and crops, but is rarely a pest.

  • Nematodes can feed on root tissues of a wide range of plant species and lead to root damage which can result in significant crop yield loss.

  • Reddish-grey, pie-shaped body, with red legs and two long forelegs

    Bryobia mite, also known as clover mite, is a sap-sucking pest of broadleaf crops and pastures, that can seriously damage canola especially where there has been a 'green bridge' consisting of clove

  • Vegetable beetle adult

    A widespread beetle is mainly a pest of summer crops, but has seriously damaged young canola in southern districts, especially when there has been a warm start to the growing season.
