Larval B. microplus were placed on 36 domestic dogs, about half of which were adults and half were puppies. Ticks matured on the adults only. The yield of adult female ticks was very low and variable (average for all dogs, 0.01%); more time was needed to mature than on cattle, and size and egg production were reduced. Most of the resulting larvae matured successfully when placed on cattle. No ticks matured on the small number of young foxes and dingoes which were tested. It is suggested that the unconsidered presence of dogs represents some risk to the success of campaigns to eradicate this tick.

Males And Females

Purebred Sahiwal cattle acquired resistance to Boophilus microplus in a similar manner to crossbred Sahiwal cattle as previously reported. The purebred entire males and females were more resistant than a control group of crossbred steers because they dropped significantly fewer replete ticks than the crossbreds at the third and fourth, but not at the first and second infestations. Adult female ticks dropped by purebred animals were significantly lighter than those dropped by crossbred animals at the fourth infestation only. There was no significant difference in the numbers of eggs laid and hatched from ticks dropped by purebred and crossbred animals. Australian Illawarra Shorthorn steers developed resistance at a second and third infestation which waned at a fourth infestation, but individual steers displayed developing resistance throughout the four infestations. Day of modal drop of replete female ticks appeared to be affected by breed, and developing resistance or season.

Boophilus Microplus Ticks

The development of a resistance by cattle to artificial infestations with Boophilus microplus ticks is reported and the sequence of development discussed. There was a regression of adult female ticks becoming replete with infestation (regression y = 2399.41 – 574x ± 54) up to the fourth infestation. The weight of replete female ticks dropped from resistant cattle increased with infestation but this effect is confounded with the effects of climate. The day of modal drop of replete females increased with infestation, which indicated an effect of resistance on modal drop. Egg-laying was not affected by a developing resistance, but the fertility of eggs from female egg-laying ticks was. There was an increase in fertility of eggs laid after the second infestation.

Female Cattle

Weight of cuticle wax produced by the engorged female cattle tick, Boophihis microplus (Canestrini), and loss of body weight during egg production, have been measured at intervals between dropping from the host and completion of egg laying. 2. Wax increased in weight from 20 to 63 µg. per tick between 6 and 222 hr. after dropping. This increase took place in two stages, with the steepest increase between 6 and 54 hr. and a smaller increase between 78 and 150 hr. 3. Body weight fell by 71% between 6 and 222 hr. The rate of loss was highest during early egg production, reaching its peak on the fourth day after dropping. 4. The most rapid increase in weight of cuticle wax took place before the onset of oviposition. During peak egg production the increase was slight. During the decline of egg production cuticle wax increased slowly in weight. 5. The possible physiological function of the increased wax secretion, and its relation to general metabolic activity, are discussed.

Percentage Water Content

Changes in water content and cuticle weight during adult parasitic life of B. microplus, and the manner in which water and dry matter are utilized for egg production, suggest that capacity for cuticle growth, and thus for distension, determines water content in relation to body weight, and this in turn fecundity of the female. Figures for Australian B. microplus are compared with those for this species in Japan, where higher average engorged weight, cuticle weight, percentage water content, and numbers of eggs laid have been reported.

Single Host

Cattle ticks,Rhipicephalus (Boophilus) microplus, are a serious threat to animal health and production. Some ticks feed on a single host species while others such asR. microplusinfest multiple hosts. White tailed deer (WTD) play a role in the maintenance and expansion of cattle tick populations. However, cattle ticks fed on WTD show lower weight and reproductive performance when compared to ticks fed on cattle, suggesting the existence of host factors that affect tick feeding and reproduction. To elucidate these factors, a proteomics approach was used to characterize tick and host proteins inR. microplusticks fed on cattle and WTD. The results showed thatR. microplusticks fed on cattle have overrepresented tick proteins involved in blood digestion and reproduction when compared to ticks fed on WTD, while host proteins were differentially represented in ticks fed on cattle or WTD. Although a direct connection cannot be made between differentially represented tick and host proteins, these results suggested that differentially represented host proteins together with other host factors could be associated with higherR. microplustick feeding and reproduction observed in ticks fed on cattle.
