Weekly observations of helicoverpa trapping

Weekly Observations to 31st October

This week (24th to the 31st October) the moth trapping network detected moderate flights (30-300 individuals) of the native budworm (PDF 938.8 KB), Helicoverpa punctigera, at Jamestown.  No activity was detected at Frances.

Light activity (<30 individuals) of the cotton bollworm (PDF 1.1 MB), H. armigera, was detected at Jamestown and Frances.

When to monitor for target size larvae:

Based on these flight dates, and long term average temperatures, the target size of larvae for treatment (2-3rd instars, 10-15mm in length) should be present during the following dates:

  • Jamestown: 11th November to 21st November
  • Frances: 16th November to the 28th November

The trapping in most areas has come to an end as crops are desiccating, or being crop topped.

Monitoring is no longer required in any areas where Helicoverpa larval feeding is not economically damaging.The trapping is several areas is coming to an end as crops are desiccating, or being crop topped. Where trapping information is still relevant it will continue until it no longer is.
