Migratory Monarchs seem more resistant than non-migratory ones to parasite infections; scientists just uncovered why it is so.

Transgenic maize is more susceptible to aphids
... by caterpillars. It kills these pests by laying its eggs in them. In cages with aphid-infested Bt maize, Cotesia wasps lived almost twice as long and parasitized
37.5% more caterpillars. Hence, an increase in the number of aphids might help to control caterpillars in areas where these are a major problem.
For crickets, parasitic flies can stop the music
...ear-cut. Although fewer males sing in the fall, for example, the ones that sing do so far longer, placing themselves at even greater jeopardy of being parasitized
