iMapPESTS deployed Sentinel 1 to project partner Sugar Research Australia’s Meringa site near Cairns in Far North Queensland to test out how it would operate under the adverse environmental conditions growers & primary producers experience during the wet season.

The unit features one six-metre insect trap, a two-metre insect suction trap and two spore suction traps, as well as an onboard weather station. Priority pests and pathogens for sugar, grains, and horticulture were targeted for identification at this site.

Insect pests targeted

Sugarcane planthopper (Perkinsiella saccharicida)

Green peach aphid (Myzus persicae)

Green mirid (Creontiades dilutus)

Western flower thrips (Frankliniella occidentalis)

Melon cotton aphid (Aphis gossypii)

Green vegetable bug (Nezara viridula)

Onion thrips (Thrips tabaci)

Fungal pathogens targeted

Sugarcane smut (Sporisorium scitamineum)

Botrytis grey mould (Botryitis cinerea)

Sclerotinia white rot (Sclerotinia minor &/ S. sclerotiorum)

Sugar Research Australia’s Meringa site trial, Cairns 2020

The SRA Meringa trial was cut short in response to increasing concerns with movement around the country due to the coronavirus pandemic. During its short trial in the region, insect and pathogen samples were collected and analysed. We report the results here.

 General pest observations

It was expected that the insect samplers would trap aphids, mealybugs, thrips, multiple leafhopper species & planthoppers, however, no insect species from the iMapPESTS high priority list for industry were identified during trap analysis by SARDI entomologists for this trial.

There was a detection of an exotic pest threat known to present in the Cairns region was detected, the Asian honey bee (Apis cerana). You can find out more information on the Asian honey bee here.

Sugarcane smut was detected during the trial and the data will be shared here when available.
