Suspected fall armyworm case at Hillston

They highlighted that it is only a suspected case at this stage and confirmation will arrive next week.

It comes after fall armyworm moths and larvae were found in traps east of Narrabri and west of Wee Waa in October, following an initial detection of a single male moth in a pheromone trap between Moree and Boggabilla on September 23.

There hasn't been a case confirmed in southern NSW.

LLS said the insect pest is a serious threat to a wide range of industries including grain, rice, cotton and vegetables.

Populations of fall armyworm have already been established in northern Western Australia, Northern Territory and Queensland since first being identified in Australia in early 2020.

LLS said they anticipate that the pest will impact NSW summer cropping with flights moving into NSW from northern states.

Growers are urged to check their crops with early detection key to minimising the spread and impact.

Small larvae are difficult to identify in the field, but they are often pale green to brown, with a dark head capsule.

Larger larvae have some characteristics that make identification easier. They have...

- A dark head capsule with a distinct upside down Y shape between the eyes.

- Two dark dots with spines on each upper body segment

- Four dark spots arranged in a square on the last abdominal segment

- Three pale lines running the length of the body may be seen on larger larvae.

If you suspect fall armyworm you must report it immediately to NSW DPI by one of the following methods.
