Four species of Cuscuta were found to primarily parasitize
seven woody and subwoody species, as well as two annual and two herbaceous perennial species within the study area (Table 1).
Other parasitic wasps include Aphytis melinus, which attacks red scale; Metaphycus helvolus, which attacks black scale; and several species of Trichogramma which parasitize
the eggs of pest worms such as corn earworms and cabbage worms.
Regardless of the specific physical characteristics potentially used by female cowbirds to locate and parasitize
nest sites of phoebes, our results are consistent with the hypothesis that site-specific physical differences between the nests may contribute to long-term patterns of being exposed to avian brood parasitism within and across years.
Pseudapanteles dignus parasitizes
all larval instars of its hosts.
In addition to characteristics of hosts, decisions made by the cowbird, such as whether to remove an egg of the host or to multiply parasitize
a host, may also affect success of the host, but these behaviors are poorly understood.
Other varieties of Cordyceps mushrooms parasitize
and alter the behavior of caterpillars, mealybugs, and beetles.
The results of this study, although based on a limited number of free-ranging coyotes, suggest that in the geographic range of the study, coyotes likely play little or no role in the endemic maintenance or spread of other species of Ehrlichia that commonly parasitize
domestic dogs or humans.
The German roaches hold on to their egg cases, and so far, scientists have found nothing that will parasitize
them, she laments.
Farrell and his colleagues at the University of Maryland in College Park have begun to sketch the broad evolutionary influence of insect herbivores and the plant species they parasitize
-- which together make up an astonishing 25 percent of all species on Earth.
Many species of the genus Philornis (botflies) within the Muscidae parasitize
nestlings and adults of cavity and open-nesting birds in the Neotropics (Arendt 1985a).
Now, a leading toxoplasmosis investigator reports data showing that another, long-unrecognized protozoan -- able to parasitize
many of the same hosts--has for decades masqueraded as a particularly virulent form of the more familiar Toxoplasma gondii.
Belvosia Robineau-Desvoidy (Diptera: Tachinidae) species parasitize
caterpillars and pupae of moths of the families Hesperiidae, Noctuidae, Saturniidae and Sphingidae (Arnaud 1978).
