Do you have Harlequin Bug?

By Kevin Dodds

Harelquin Bug has been noticed in some Batlow orchards. Kevin Dodds from NSW DPI wants to know if you’ve found it or are having problems with it in your orchard.

Adult Harlequin Bugs are about 12mm long with a black head, inner margins and forewing tips, and the base of their forewings is a reddish-orange.

I recently published a NSW DPI PrimeFact on Harlequin Bug in apple orchards. In it I reported on a survey of 20 apple growers in the Batlow district of NSW that showed that Harlequin Bug is a significant pest in local orchards, causing damage to fruit. Estimated damage levels (as an average over their entire crop) ranged from 1-10 per cent of fruit. However, localised damage on a specific variety or in a particular location was reported to be as high as 75-100 per cent of fruit.

So far my research has indicated that it’s primarily an issue in Batlow, NSW. However, I’d be interested in feedback from growers in other production districts (particularly in south eastern Australia) who might recognise the bug.

This pest really needs further study by an entomologist, but unless we can establish that it’s a problem in other districts it may struggle to receive attention.
