1 the relationship that exists between parasites
The exact rate of parasitism is of great importance in making decisions about whether or when to apply insecticides.
Mortality was caused by a variety of factors, including parasitism.
All five species of large blue butterflies in Europe engage in this form of parasitism on red ants.
Parasitism is reported as low, often with no response to host density and unlikely to have an impact upon the host population.
In the present study, both discovery and parasitism efficiency decreased with increasing egg batch density.
Levels of natural populations of larval parasitoids were measured by their parasitism rate.
No differences were found among the mixed cropping treatments and parasitism was lower during the long compared to the short rainy seasons.
A host's ability to counter the negative aspects of parasitism could depend upon a multitude of variables.
