Do bot flies, Cuterebra (Diptera: Cuterebridae), emasculate their hosts?
Asa Fitch, in his description of a new species of Cuterebra that he nzrr'ed, "emaseulator," was the first to suggest that bot flies castrated their mammalian hosts. In recent years several major review papers and parasitology texts have continued to perpetuate this belief. A review of both the literature on bot flies and their hosts and of the life cycles of both bots and hosts provides no evid...
متن کاملNematode endoparasites do not codiversify with their stick insect hosts
Host-parasite coevolution stems from reciprocal selection on host resistance and parasite infectivity, and can generate some of the strongest selective pressures known in nature. It is widely seen as a major driver of diversification, the most extreme case being parallel speciation in hosts and their associated parasites. Here, we report on endoparasitic nematodes, most likely members of the me...
متن کاملDo Fleas Affect Energy Expenditure of Their Free-Living Hosts?
BACKGROUND Parasites can cause energetically costly behavioural and immunological responses which potentially can reduce host fitness. However, although most laboratory studies indicate that the metabolic rate of the host increases with parasite infestation, this has never been shown in free-living host populations. In fact, studies thus far have shown no effect of parasitism on field metabolic...
متن کاملResistance is futile but tolerance can explain why parasites do not always castrate their hosts.
The disease caused by parasites and pathogens often causes sublethal effects that reduce host fecundity. Theory suggests that if parasites can "target" the detrimental effects of their growth on either host mortality or fecundity, they should always fully sterilize. This is because a reduction in host fecundity does not reduce the infectious period and is therefore neutral to a horizontally tra...
