So far it seems that locust numbers in the cropping areas are lower than feared. Some small, localised bands have been treated by farmers. Most hoppers are reported from the edge of paddocks and roadsides as hoppers prefer open vegetation. Further
PestFacts SA has received several reports of spray failure using synthetic pyrethroids against budworms in peas in the mid north – mostly native budworm and an occasional lesser budworm. No cotton bollworm (Helicoverpa armigera) caterpillars have
As canola crops move through pod fill and begin to ripen, Rutherglen bug (Nysius vinitor) is a pest worth keeping an eye on. Rutherglen bugs are small but highly mobile insects that can seem to appear almost overnight. Adults are around 4 to 5 mm
The risk of plague locust activity has risen significantly across parts of South Australia following favourable seasonal conditions. Increased egg laying and high locust numbers across some regional areas and neighbouring states to the east are
The recording of the PestFacts SA September webinar is now available – so if you missed it, you can watch it anytime, or you can revisit any of the topics covered. Presented by SARDI Senior Entomologist Dr Maarten van Helden and Cesar Australia
Native budworm (Helicoverpa punctigera) is a major pest of pulses, including field peas and lentils, and can also cause damage in canola. The moths themselves don’t cause damage – it’s the larvae we need to worry about. Moth activity gives us
Do you feel spring in the air? So do the insects in canola crops! As temperatures rise and canola moves through flowering and pod development, insect activity starts to pick up. Pests such as diamondback moth, green peach aphid, cabbage aphid and
After a few weeks of little to no native budworm (Helicoverpa punctigera) activity across South Australia, recent pheromone trap catches show moth activity picking up again at several monitored sites. Recent trap catches recorded:. Port Broughton
Redlegged earth mite (RLEM) is a major pest of Australian crops and pastures across the southern states. Chemical control remains an important management tool, but insecticide resistance is making some treatments less effective. Resistance to both
When our team receives images of aphids for identification, our focus is usually on determining the species and assessing potential crop risk. However, this season we've also noticed something else appearing in several submissions: pale, shrivelled
The SARDI pea weevil model is predicting that adult pea weevil movement into field pea crops could begin around 25 August, with egg-laying activity expected from approximately 8 to 10 September. Pea weevil (Bruchus pisorum) adults spend summer,
Etiella (Etiella behrii) can be a difficult pest to stay ahead of in pulse crops. Adults can arrive with little warning. They lay eggs on plants, and after hatching, the small larvae move into developing pods where they feed on seeds. Once larvae
