“…In Western Australia, 41 legumes of the genera Gastrolobium and Oxylobium produce fluoroacetate (Twigg, 1994), which is metabolised to toxic fluorocitrate (McIlroy, 1982). Fluoroacetate is also formed by hydrolysis of sodium monofluoroacetate (1080).…”

“…Considered the most adaptable of the Australian marsupials (Kerle, 1984b), the possums of Western Australia have the highest recorded mammalian tolerance of fluoroacetate (King et al 1978;Oliver et al 1979;McIlroy, 1982) allowing them to utilise these nutritious legumes in amounts that would constitute a toxic meal for possums from other areas.…”

of a thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science Implications of prefeeding for the development of bait aversions in brushtail possums (Trichosurus vulpecula) by Zane N. Moss The first cage trial determined the effects of prefeeding on aversion development. Three treatment groups received for 7 days either i) no prefeed ii) plain prefeed, or iii) dyed and lured prefeed baits. Each possum then ingested a sub-lethal 1080 bait. Seven days later, the possums were tested for development of an aversion towards a 1080 bait, a prefeed bait, and a prefeed bait containing brodifacoum. Most (96%) non-prefed possums became averse to the 1080 bait, compared with only 55% and 9% of the two prefed groups.Similarly, over 90% of the non-prefed possums were averse to prefeed and brodifacoum baits, compared to <15% of the prefed possums. The trial also showed that novelty has an influence on possums' aversion development; as prefeed and toxic baits became more similar (i.e. the more cues shared), fewer prefed possums were able to distinguish between the two after sub-lethal poisoning and so few developed aversions.The second cage trial examined the influence of bait cues and prefeeding duration on possums' development of aversion. Three main treatment groups received either i) dyed, ii) cinnamon lured, or iii) dyed and lured prefeed baits, for either 1 or 7 days.iii Mter sub-lethal poisoning possums were tested for aversion towards a 1080 bait and a prefeed bait. Once again the influence of familiarity was apparent, with only 34% averse to the toxic bait, significantly less than for non-prefed possums (cf. trial one). Dye seemed to provide relatively weak cues linking prefeed and toxic bait, with 7 days prefeeding required to inhibit aversion development. In contrast, cinnamon appeared to provide relatively strong olfactory and/or taste cues linking prefeed and toxic baits, with one exposure to cinnamon lured prefeed sufficient to inhibit aversion development. As in the first trial, most of the possums that developed aversion to the toxic bait did not generalise this aversion to the prefeed bait. Some possums were seemingly able to detect 0.08% 1080, despite it being' masked' with cinnamon oil.The field trial aimed to validate results of the cage trials and to examine whether possums preferentially associate certain cues with poisoning. Two treatment groups received either cinnamon lured baits, or apples, for 3 weeks. Mter sub-lethal poisoning possums were tested for aversion towards a non-toxic prefeed bait, a dyed non-toxic bait, a toxic bait, and a dyed toxic bait, all of which contained cinnamon. Once again most non-prefed possums developed generalised aversions, avoiding all cereal baits. In contrast, prefed possums consumed familiar prefeed baits, but avoided all other baits. This demonstrated that possums could detect both dye and 1080 in a cinnamon-lured bait. This result also suggests that extended prefeeding may enable possums to distinguish between prefeed a...

“…Given the tolerance of Western Australian fauna species to 1080 poison, it is unlikely that any of the observed non-target species in the present study would have ingested a lethal dose (McIlroy 1982(McIlroy , 1983(McIlroy , 1984(McIlroy , 1986Twigg and King 1991;Twigg et al 2009), although this cannot be confirmed without searches post baiting; even then, the likelihood of finding potentially poisoned carcasses would be very low.…”

Context: In Western Australia, baits containing 1080 poison are widely used to control the red fox (Vulpes vulpes) for fauna conservation. Despite long-term (15-17 years) baiting programs, bait uptake by target and non-target species is largely unknown, but affects baiting efficacy. Aims:We examined bait uptake of 1080-poisoned fox baits laid according to current practice at seven riparian sites in the northern jarrah forest (of south-west Western Australia). There, intensive baiting regimes have been implemented for the protection of quokka (Setonix brachyurus) populations.Methods: Over 9 months, 299 Probait ® baits were monitored regularly to determine their persistence, and, at 142 of these, Reconyx HC500 remote cameras were used to identify the species taking baits.To compare bait uptake with species presence at these sites, we calculated an activity index for each species from the number of passes of animals in front of the cameras.Key results: The species taking baits was identified for 100 of the baits monitored with cameras, and, because of multiple species taking baits, 130 bait take incidents were recorded in total. The fate of 40 of the baits was not discernible and two baits were not removed. In all, 99% of baits monitored by cameras were taken by non-target species and quokkas took 48% of them. The majority of baits (62% of the total 299 monitored) were taken before or on the first night of deployment, and 95% of baits had been taken within 7 days. With the exception of feral pigs, which took more baits than predicted from their activity index at these sites, baits were taken in proportion to the activity index of species.Foxes were present at four of the seven sites, but only one fox was observed taking a bait. Conclusions:The high level of uptake of baits by non-target animals reflects their diversity and abundance at these sites, but also significantly reduces the availability of baits to control foxes.Implications: Strategies to reduce non-target bait uptake and increase bait availability for foxes are required.

Desde 1955, essa substância tem sido usada especialmente na Austrália e Nova Zelândia para controlar coelhos europeus (Oryctolagus cuniculus), dingos (Canis familiaris dingo), porcos selvagens (Sus scrofa), marsupiais australianos (Trichosurus vulpecula) e várias espécies de canguru (McIlroy 1981, 1982a, Twigg & King 1991.

O monofluoroacetato (MF) ou ácido monofluoroacético é utilizado na Austrália e Nova Zelândia no controle populacional de mamíferos nativos ou exóticos. O uso desse composto é proibido no Brasil, devido ao risco de intoxicação de seres humanos e de animais, uma vez que a substância permanece estável por décadas. No Brasil casos recentes de intoxicação criminosa ou acidental têm sido registrados. MF foi identificado em diversas plantas tóxicas, cuja ingestão determina "morte súbita"; de bovinos na África do Sul, Austrália e no Brasil. O modo de ação dessa substância baseia-se na formação do fluorocitrato, seu metabólito ativo, que bloqueia competitivamente a aconitase e o ciclo de Krebs, o que reduz produção de ATP. As espécies animais têm sido classificadas nas quatro Categorias em função do efeito provocado por MF: (I) no coração, (II) no sistema nervoso central (III) sobre o coração e sistema nervoso central ou (IV) com sintomatologia atípica. Neste trabalho, apresenta-se uma revisão crítica atualizada sobre essa substância. O diagnóstico da intoxicação por MF é realizado pelo histórico de ingestão do tóxico, pelos achados clínicos e confirmado por exame toxicológico. Uma forma peculiar de degeneração hidrópico-vacuolar das células epiteliais dos túbulos uriníferos contorcidos distais tem sido considerada como característica dessa intoxicação em algumas espécies. O tratamento da intoxicação por MF é um desafio, pois ainda não se conhece um agente capaz de reverte-la de maneira eficaz; o desfecho geralmente é fatal
