Abstract Effective border control relies on stringent biosecurity protocols to detect and prevent introductions of exotic pests diseases. Detection pathogens parasites in the live ornamental fish trade using environmental DNA (eDNA) techniques has potential improve current practices. We examined water samples from 11 target consignments (cyprinids susceptible Dactylogyrus spp. infections) seven non-target (non-cyprinids, not imported Southeast Asia Australia for presence eDNA five species...

Abstract Environmental DNA (eDNA)‐based methods are increasingly used by government agencies to detect pests and threatened species, for broader biodiversity monitoring. Given rapid technological advances a growing number of commercial service providers, there is need standardize quality assurance maintain confidence in eDNA‐based results. Here, we introduce two documents provide best‐practice guidelines Australian New Zealand eDNA researchers end‐users (available from...

Khapra beetle, Trogoderma granarium Everts, 1898, is a serious pest of stored grain products globally. Environmental DNA (eDNA)-based methods offer sensitive detection tools used to inform biosecurity officers on the presence high-risk pests. This study tested laboratory and portable molecular technologies detect khapra beetle environmental extracted from dust samples collected during responses (Tuggeranong Fyshwick) incursions in Australia. Airborne floor were opportunistically using...

The infection dynamics and distribution of the ectoparasitic fish monogenean Neobenedenia sp. (Monogenea: Capsalidae) throughout its development was examined on barramundi, Lates calcarifer (Bloch) (Latidae), by labelling transparent, ciliated larvae (oncomiracidia) with a fluorescent dye. Replicate were each exposed to approximately 50 oncomiracidia then for parasites using an epifluorescence stereomicroscope at 10 time intervals post-exposure (15, 30, 60, 120 min, 24, 48 h, four, eight,...

Abstract Environmental DNA (eDNA) monitoring has revolutionized the way biodiversity is surveyed and been proposed as a reliable method to inform management decisions. Recognition of eDNA techniques tools biosecurity require stringent standards assess sample quality reliability results. Laboratories can have their workflows assessed certified through accreditation be involved in proficiency testing schemes provided test accuracy precision molecular methods. Currently, there only one...

This preliminary study used DNA metabarcoding to test whether the stomach content and gut microbiome of tuna could be a viable near real-time monitoring tool for detecting composition change in oceanic ecosystems. The skipjack ( Katsuwonus pelamis , n=55) yellowfin Thunnus albacares n=46) captured Pacific Ocean during El Niño Southern Oscillation events (ENSO) between 2015-2017 were examined by high throughput sequencing complemented morphological assessments identify fishes, crustaceans...

Context Biological resource use represents the most common direct threat to biodiversity. Despite this, there is a paucity of comprehensive and overarching data relating biological use. The global aquarium trade encompasses millions individual live fishes representing thousands marine freshwater species traded on an annual basis. lack specific systems for recording information where fish are exported or imported has resulted in limited accessible data. An evaluation data-reporting frameworks...

Terrestrial invasive invertebrates can rapidly colonise new areas, causing detrimental effects on biodiversity, economy and lifestyle. Targeted environmental DNA (eDNA) methods could constitute an early detection tool given their sensitivity to small numbers of individuals. We hypothesised that terrestrial runoff would transport eDNA from the land into adjacent waterbodies used yellow crazy ant ( Anoplolepis gracilipes ) as a model species test this hypothesis. collected water samples four...

The ornamental fish trade provides a pathway for the global translocation of aquatic parasites. Myxozoa is comprised highly specialized metazoan parasites hosts with wide host range. Interest in group has intensified along development aquaculture due to emergent pathogenic myxozoan species both freshwater and marine environments. However, little known on diversity trade. We examined 630 imported from Asia Australia (representing 24 populations, including wild caught species) during 2015....

Abstract Environmental DNA (eDNA) surveys have gained popularity as a highly sensitive detection tool that generally outperform traditional techniques. eDNA can provide cost-effective means to identify species’ distributions and recent incursions, informing the control or containment of invasive species. The red-eared slider turtle, Trachemys scripta elegans , is one world’s most species listed priority pest for management in Australia. In this study, we validate two assays detect turtle We...

Abstract The giant freshwater crayfish, Astacopsis gouldi Clark, 1936, is an endangered endemic species native to Northern Tasmania. Habitat loss, fishing pressure, and climate change have been identified as threatening processes. Australian government approved a recovery plan for A. in 2017 that requires routine population surveys assess the impact of ongoing threats actions. We developed novel species‐specific probe‐based assay targeting 219 bp fragment Cytochrome Oxidase 1 gene region...

Indiscriminate use of insecticides to control vectors malaria, dengue, and yellow fever contaminates the environment with time, gradually increases insecticide-resistant mosquitoes, making their increasingly difficult. Use parasitic nematode Romanomermis iyengari (Mermithidae) is efficient biological against but little known effect habitat complexity on success infection.
