A review of Bactrocera bryoniae (Tryon) and revised distribution in Asia and Australia, with a focus on New South Wales

Dominiak, B. and Millynn, B.

Bactrocera bryoniae is commonly found in Northern Australia with occasional detections in New South Wales (NSW). We reviewed host records and the distribution in Asia, Australia and particularly NSW. We reviewed 19 years of NSW surveillance records and revised the eastern and southern distribution. We conclude that there are resident populations as far south as Coffs Harbour with two annual population peaks. There was little evidence for a resident population inland at Guyra. The populations in the Newcastle/Sydney/Wollongong region were transient in most years with one annual peak (November) in 2019. Since then, we detected significant populations occurring between October and April in 2020/2021 with two peaks in November and January.

Megoura crassicauda Mordvilko (Hempitera: Aphididae), a potential threat to Faba bean industry in New South Wales

Duric, Z., George, J. & van Leur, J.

The oligophagous aphid species, Megoura crassicauda Mordvilko (Hemiptera: Aphididae), is a legume pest originating from east Asia.  It was first detected in Australia in October 2016 in a Sydney home garden and was subsequently found in a faba bean crop in north west New South Wales in 2017.  A distribution survey was carried out to determine the presence of M. crassicauda in northern NSW in 2018, 2019 and 2020.  In 2020 presence of M. crassicauda was confirmed at several locations across NSW. The biological characteristics of M. crassicauda were examined to evaluate its potential impact on the Australian pulse industry. Host range studies included faba beans, vetches, common pea, lentil, subclover and lucerne. Faba bean was found to be its preferred host with the aphid forming large colonies on leaves, stems and pods in only a few days. As there is no English common name for M. crassicauda, we suggest ‘Faba bean aphid’ because of its clear preference for this host. The aphid was found to transmit Bean leafroll virus and Pea seed-borne mosaic virus between faba bean plants. This pest presents a serious threat to the Australian faba bean industry due to its fast reproduction and colonisation of faba bean and its ability to transmit important viruses.
