Eight feral pigs (two boars, four sows and two piglets) were caught in traps using oestrous sows as lures during a control program on a remnant pig population in part of Namadgi National Park during spring, 1990. The program was mostly based on aerial baiting with warfarin. No pigs were caught in traps containing anoestrous sows or in traps containing bait only. Seven unmarked pigs (caught seven days after the cessation of baiting) did not appear to have eaten any warfarin bait. In an earlier pilot trial, two boars were caught at a trap containing an oestrous sow, one of these again in a trap baited only with fermented grain, but no pigs were caught at a trap containing an anoestrous sow. Although not cost-effective as a general technique, this method could be useful in specific circumstances, such as eradication campaigns on islands, if the last few pigs are, or have become bait shy, or are impossible to cull by other methods.

A partir de amostragens em campo com os métodos de busca ativa e armadilha fotográfica são apresentados registros de porcos silvestres no Município de João Pinheiro, uma área de Cerrado no Noroeste de Minas Gerais. O estudo foi conduzido em paisagens de várzea, campina, mata seca e chapada, compostas por remanescentes de diversas fitofisionomias e áreas de uso agropecuário. Grupos de Tayassu pecari (queixada), Em Perigo em Minas Gerais, foram registrados em 14 localidades em uma mesma região de grande planície de interflúvio com extensos remanescentes conservados, ocorrendo possivelmente em uma estrutura de metapopulação. Grupos de Pecari tajacu (caititu), Vulnerável em Minas Gerais, foram registrados em 20 localidades, exibindo maior distribuição geográfica, e ocorreram em remanescentes com distintos estados de conservação. Grupos estabelecidos de Sus scrofa híbridos (javaporco), espécie invasora, foram registrados em uma área. São apresentadas observações de história natural, destacando-se o consumo de diversos frutos do Cerrado e movimentos sazonais em função de frutificação exercido por T. pecari, e formação de grandes grupos e possível comportamento de piscivoria por P. tajacu. Os registros de T. pecari correspondem às primeiras ocorrências confirmadas da espécie em áreas externas a Unidades de Conservação recentemente em Minas Gerais. São discutidas ameaças locais a T. pecari e P. tajacu, destacando-se a destruição e fragmentação de habitats no contexto do histórico de ocupação do solo no município, distintas modalidades de caça e, potencialmente, a intervenção gerada por S. scrofa. Com base nos registros obtidos, nas relevantes ameaças identificadas e na conhecida maior susceptibilidade de T. pecari a extinções locais, suspeita-se que a população de queixada de João Pinheiro esteja fadada à extinção, a menos que grandes remanescentes naturais sejam efetivamente protegidos em Unidades de Conservação.

ABSTRACT: Family Tayassuidae in the suborder Suina include two species of peccaries in Brazil: the white-lipped peccary (Tayassu pecari) and the collared peccary (Pecari tajacu). These animals share common pathogens with domestic swine (Sus scrofa); however, their role as potential carrier remains unclear. This study focused on detecting the prevalence of influenza A antibodies in Tayassu pecari and Pecari tajacu from commercial rearing farms from two states in Brazil. A set of 50 blood samples from Pecari tajacu and 55 from Tayassu pecari were analyzed using a commercial indirect ELISA in order to investigate anti influenza A antibodies. Pecari tajacu samples presented 22% (11/50) of seropositivity for the virus. Serological surveillance is an important tool to identify the presence and the spread of the influenza virus in feral pigs.

A warfarin poisoning programme to control feral pigs was evaluated on agricultural land in eastern Australia between July and September, 1987. The estimated total population before the poisoning programme was 189 pigs within the 94.4 km2 study area. Poisoned and free-fed bait was offered initially at 69 sites and over a period of 57 days. Only two pregnant sows were believed to have survived the programme which was equivalent to a 98.9% reduction. As a result of breeding and re-invasion a further 38 pigs were removed in the 12 months after the control programme. Cost of initial control was $A39 per pig while cost of maintenance control was $A47 per pig.

The aim of this study was to develop better techniques for controlling feral pigs, Sus scrofa, in the event of an outbreak of an exotic disease than the use of 1080. Trail-baiting with warfarin-treated wheat killed 30 of 32 feral pigs carrying radio transmitters in Namadgi National Park, A.C.T., in May 1986. The casualties took 9.7 � 0.4 (mean � s.e.) days to die (range 6-14) and all died within 2.06 km of the bait trail. The two survivors (both males) were radio-located within 339 m of the poison trails several times, but then moved 5.1 and 1.5 km, respectively, out of the trial area. Home ranges averaged 4.7 � 0.6 km2 (range 0.7-22.6) and the population density was approximately 2 km-2. The pigs' mobility did not alter as death approached. They moved equal distances during the day and the night. Differences in mobility between the sexes were generally minor.
