0 If a part of the body is engorged, it has become swollen or filled with a liquid, especially blood.
Finally, there are daily rates of mortality, which are specific to each stage and state (questing, feeding and engorged).
Relationships between these aspects of size in the moulted adult ticks and their weights as engorged nymphs were then investigated.
The effect is to permit a higher percentage attachment and engorgement by feeding ticks, and better subsequent survival by engorged ticks.
For the oviposition experiments, blackflies were allowed to bloodfeed until fully engorged.
Ticks that had engorged and detached were harvested on days 4, 5 and 6 after tick application.
In addition, 28 out of the 30 engorged nymphs were found on animals that were also infested with larvae.
We have also investigated potential relationships between the weights of engorged nymphs and post-moulting survival of adult ticks via effects on adult tick size.
Anecdotal evidence suggests that even large larval infestations are likely to yield very few engorged adult ticks.
