sustainability through science & innovation
Agronomist, Matthew Burkitt (Central West Agricentre), has reported Etiella (Etiella behrii) caterpillars in narrow leaf lupins, 30km east of Parkes, in the Central West Slopes and Plains district of New South Wales. Between 1-2 caterpillars were found in pods that were inspected. Matthew says Etiella are typically found in low numbers and only a minor pest in the district. Etiella moths were also seen in many lentil crops in early spring, with some reports suggesting Etiella have been more prevalent this season than in previous years.
Etiella (also known as the ‘lucerne seed web moth’) is a sporadic pest of lentils, lucerne, field peas and pasture legume crops. Successful control relies on thorough crop monitoring, with management mostly based on timing insecticide sprays to target adult moths within the crop before egg lay commences. Sprays applied to control native budworm early in the podding period may have provided some level of control for Etiella if present.
Typically only the first generation of Etiella are a concern for growers. However, in seasons that finish late, the second generation may also cause significant seed damage.

What is PestFacts?
PestFacts south-eastern keeps growers and advisers informed about invertebrate pests and beneficials in broadacre crops and pastures during the winter-cropping season in Victoria and southern New South Wales.
PestFacts south-eastern is run through IPMforGrains: Best Practice Insect Pest Management, a project delivered by the National Pest Information Network (cesar, DPIRD, QDAF, NSW DPI, and SARDI). This project aims to provide grain growers and advisors with information on invertebrate grain pest occurrence and equip industry with the knowledge needed to implement integrated pest management practices. This initiative is a GRDC investment and includes in-kind contributions from all project partner organisations.
We need your reports
PestFacts is produced on an ʻas-needsʼ basis and relies upon pest observations and field reports from our subscribers. If you have recently observed invertebrate pests (or beneficial species) in broadacre crops, please contact us to report your observations.
Agricultural invertebrate identification
If you are a grower or agronomist in Victoria or NSW working with broadacre crops or pastures, we can assist you with identifying invertebrates found on farms at no cost. Please contact us for identification help.
PestFacts map
PestFacts map is an interactive tool that allows users to search and view historical pest reports across Victoria and NSW. The map is updated with each issue of PestFacts to include new reports.
