“…This bacterium is well reported in wood-eating insects since it can also help in wood fermentation (Montagna et al 2015). Notably, the larvae of D. abbreviatus feed on roots and stems, thus this genus could be acquired during this early development stage (Bates et al 2015). Staphylococcus spp.…”

“…It can metabolize alanine, galactose, lactose, maltose, mannose, N-acetylglucosamine, rhamnose, serine, trehalose, and xylose (Reimer et al 2022). Since the adult D. abbreviatus emerges from the soil, it is possible that this bacterium may be acquired during the larval stage (Bates et al 2015). This species of bacteria was present exclusively in the feces of D. abbreviatus fed the passion fruit.…”

The EFSA Panel on Plant Health performed a pest categorisation of the citrus root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) for the European Union (EU) following the commodity risk assessment of Ligustrum delavayanum topiary grafted on L. japonicum plants from the UK in which D. abbreviatus was identified as a relevant non-regulated EU pest which could potentially enter the EU. This species is native to the Caribbean and was introduced to the continental USA in 1964, to Gran Canaria (Spain) in 2014 and to Madeira Island (Portugal) in 2018. It is a polyphagous insect, associated with more than 270 species in 60 plant families. Female D. abbreviatus can lay up to 5,000 eggs in clusters within leaves folded and glued together. Neonate larvae drop off the leaves onto the ground and enter the soil, where they feed on roots for several months. The mature larvae pupate in the soil. After emergence, adults usually stay on the first host plant they encounter and can move long distances on nursery stock. D. abbreviatus is not a regulated pest in the EU. It could enter and spread within the EU via the import and movement of host plants for planting, cut flowers and soil. Some host plants for planting (e.g. Vitis spp., Citrus spp.), and soil are prohibited from entering the EU from countries where this weevil is known to occur. The import of other host plants for planting and cut flowers is subject to phytosanitary certificate and that of soil attached to machinery is regulated. Host availability and climate suitability suggest that the southernmost coastal areas of southern EU MSs would be suitable for establishment of D. abbreviatus. Temporary establishment in greenhouses in other EU territories would be possible. The introduction of D. abbreviatus would likely cause impacts. Measures to prevent entry, spread and impact are available. D. abbreviatus satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

“…Movement likely was motivated by crowding at the central plant and a resulting search for new food resources, because most of the central plants were severely wilted or dead by the end of the experiment. Vertical movement of D. abbreviatus neonates has been studied (Quintela & McCoy 1998), and larvae typically remain in about 1 m radius of citrus tree trunks (Bates et al 2015), but little is known about horizontal movement of late-instar D. abbreviatus in soil. A couple D. abbreviatus larvae were recovered from distal plants, suggesting movement of almost 1 m in 7 wk is possible but not common.…”
