| Popis: | Larval Arrenurus mites establish a phoretic association with pupal mosquitoes and wait for emergence of the adult upon which they feed. In the laboratory, four Aedes spp. were given equivalent exposure to larvae of Arrenurus angustilimbatus Mullen and Arrenurus kenki Marshall. For both species of mites, Aedes excrucians (Walker) and Aedes cinereus Meigen were less than half as likely to be parasitized than were Aedes communis (DeGeer) and Aedes punctor (Kirby). Both mite species were apparently equally attracted to all four mosquito species, but upon contact they were far less likely to remain in phoretic association with A. excrucians and A. cinereus. Aedes cinereus displayed an avoidance response that reduced the number of phoretic mites by a factor greater than 10 while the larval mites would swim away from pupal A. excrucians in over 85% of the contacts. Larval A. angustilimbatus had differential success when transferring to the adult mosquito host (59.2% success on A. excrucians, 48.7% on A. punctor, 37.6% on A. cinereus, and 31.8% on A. communis). Once attached, the mites' engorgement success was almost 100% on all host species. |
