Water buffalo in the Northern Territory of Australia have a well defined breeding season in the wet or very early dry season. The birth of a calf is of major importance for the clan and for the family group of which that clan is a part. A number of calves are left in the care of an adult while their mothers go to graze. The female calf remains with its mother for many years, possibly for life, but at 2-3 y old the male calf is driven from the group by an adult bull when a cow in the group comes into oestrus. Most buffalo cows will readily adopt an orphan calf and within 8 days it is impossible to distinguish between the orphan and the group calves.

Northern Portion

Regular aerial and land surveys of the coastal plains and adjoining high ground in the northern portion of the Northern Territory between the Adelaide and Wildman Rivers showed variations in the number of buffalo on the plains. When there were very few buffalo on the plains there were large numbers on the adjoining high timbered country. During the wet season the plains flooded to varying depths and in those areas where the water was very deep all buffalo moved to higher ground. In the Northern Territory the wet season is the main breeding season, and at this time adult bulls were seen with cows in oestrus. During the dry season, which is the non-breeding season, the bulls and cows inhabited separate areas; the cows and their calves preferred those areas of the black soil plains adjoining high ground where there was water, shade, and some green feed. When rain fell at the end of the dry season, the buffalo moved to areas where it had rained.

Dry Season

Data were obtained on 1094 females and 859 males killed at an abattoir, and 135 females and 32 males shot in the field. The data indicated that cows calve during the late wet or early dry season, after a pregnancy of 10-11 months. Age at 1st conception averaged 28.5 months; puberty occurred at 14-19 months. Pregnancy rate was 76% for the abattoir sample; it was <5% for females aged less than or equal to 3 yr. Bulls were probably fertile for 8 months of the year, the infertile period occurring during the 2nd half of the dry season.

ABSTRACTMicrofilariae ofOnchocerca sweetaeare broadly distributed in the superficial layers of the dermis of the water buffalo (Bubalus bubalis). A total of 2855 insects representing 20 species were collected fromO. sweetae-infected bait buffaloes. Only one species,Culicoidessp. “M”, ingested microfilariae from buffalo skin. Larval development ofO. sweetaewas observed in the thorax of this species. A total of 829 insects, representing 7 species and including 749 parousCulicoidesspp. were collected from light and Manitoba traps. Developing filarioid larvae were observed only inCulicoidessp. “M”. It is concluded thatCulicoidessp. “M” is a natural intermediate host ofO. sweetaein the Northern Territory of Australia.

The Family

Williams (1969) published a list of the family-group names in the Coccoidea (scale insects) recognised at that time. The present paper supplements this earlier list and includes all nominal genera that have had family-group names based on them, including those in the earlier paper, in case it is not readily available to some workers. Nominal genera and their family-group names are listed alphabetically in catalogue form. There are now 49 families generally recognised in the scale insects, of which 16 are only known as fossils. Furthermore, 180 nominal genera have now had family-group names based on them. As stated in the 1969 list, all categories in the family group are deemed to be of co-ordinate status in nomenclature.
