Yellow mirid

Description

Yellow mirid bugs look just like the green mirid bug but are a brownish, yellow-green and less than half the size. When the bug is squashed it has a sweet smell. The nymphs look a bit like aphids but with an elongated body, and are yellow in colour. They have dark spines on their legs (which the adults also have) and red eyes. They are very fast moving.

Adult size: 3mm

Out and about

About when the new buds are growing on trees. They are native to Australia and found in the eastern states of the mainland, particularly in the southern areas.

Reproduction and Life cycle

The female lays eggs in the buds of the plant and these will reach adulthood in about 5 weeks.

To deter

To control

These bugs are quite slow in the early mornings so they will be easier to identify before they warm up. They are more likely to be on the sunnier side of the trees. I would use a neem spray on the trees before or just as the fruit buds are forming in order to kill the larvae and then regular sprays to stop the adults as the fruit is developing.

Why they are both Beneficial & Pest
These bugs are considered more of a pest in the fruit tree industry. They need to be monitored as they can beneficial as well. On the beneficial side, both the adult and nymphs will eat small caterpillars and eggs as well as the adults and eggs of spider mites. On the pest side, they can damage growing plant tips. They feed on flowers and developing fruit, and their eggs are laid in the buds, causing scabbing and indentations in fruit that look like dimples (hence the name “apple dimpling bug”). They can be found on a range of vegetables and fruits such as apples, pears and some stone fruit, as well as Australian-native and non-native plants. They don’t cause as much damage as the green mirid
