“…This paper is one of a series, and reports the analysis of blood meals from some 11,000 insects, comprising some 7000 biting midges of 15 species and some 4000 mosquitoes of 24 species, to determine the mammalian hosts upon which they had fed. Particular attention was paid to the identification of blood meals from ox and buffalo, the latter being an abundant feral bovine in the area and potentially important as a reservoir host for both endemic and exotic diseases of livestock (Murray and Snowdon 1976).…”

One aspect of an intensive study of arboviruses and insect vectors at Beatrice Hill, X.T., was to determine the hosts of the insects by identifying the source of their blood meal. The collection methods included buffalo bait, calf-and chicken-baited Magoon traps, truck traps, light traps and collecting from insect resting places. Blood meals were identified by precipitin and haemagglutination-inhibition tests. Fifteen species of biting midges, mostly Culicoides spp., and 24 species of mosquitoes were represented in the collections, and the blood meals within 75% of some 11,000 insects were identified. The majority, 97,7%, of the blood meals were mammalian in origin, 76% being bovine and 17% marsupial. A significant proportion of the blood-fed mosquitoes from Magoon traps had fed on hosts other than the bait animal or collector. Double feeds were detected in 1.1% of the insects in which the source of the blood meal was identified. It was possible to draw conclusions about the feeding habits of most of the insect species.

“…In common with other feral animals they pose two distinct animal health problems. Feral goats may act as reservoirs for diseases already endemic in Australia and may serve as hosts for some exotic diseases should these be introduced, thereby establishing foci of infection not easily amenable to eradication or control (Murray and Snowdon 1976;Snowdon 1979).…”

Caseous lymphadenitis was the most frequently encountered pathological condition in 3,720 feral goats examined during routine meat inspection procedures. Among 9 separate consignments of animals, the prevalence of infection averaged 7.4% (range 0.3% to 18.8%). The majority of lesions were seen in lymph nodes draining superficial body areas although many also occurred in internal nodes and organs. Corynebacterium ovis was isolated from 25 of 32 lesions submitted for bacteriological examination. Other conditions regularly encountered included pneumonia, cysticercosis, sarcosporidiosis and lice infestation, while myonecrosis, pleurisy, pericarditis, nephritis, hepatitis, cirrhosis and mite infestation were only occasionally found. A total of 171 serum samples were collected and tested against 17 antigens. Samples from 57.9% and 51.5% of goats showed positive serological reactions to the antigens for sarcosporidiosis and Q fever respectively.

“…West and Saunders (2003) found that the six deer species collectively inhabit 5% of NSW and the ACT, compared to 2% in an earlier survey in 1996. Even earlier reports by Wilson et al (1992) and Murray and Snowdon (1976) suggested that wild deer inhabited smaller areas of NSW than those observed in 1996. Despite this apparent increase in the size of the wild deer population, West and Saunders (2003) noted that in contrast to the many other introduced species in NSW, a majority of respondents to their survey did not perceive wild deer to be overly abundant.…”

With their introduction into Australia beginning in the early nineteenth century deer have joined a long list of introduced species, many of which have become significant pests. Unlike rabbits, feral pigs, foxes and others, deer have not been considered to have had significant adverse environmental or socioeconomic impacts in Australia until quite recently. There are long-standing wild populations in several states that have been managed for many years as a valuable resource for hunting rather than as a pest. In very recent times a perception has developed that wild deer numbers are increasing in Australia, with a wider distribution. The basis for these concerns will be examined, with a review of wild deer management in Australia.
