Invertebrates are outstanding model systems for the study of aggression. Recent advances
and promising new research approaches are bringing investigators closer to the goal of …

Parasites often alter the behavior of their hosts in ways that are ultimately beneficial to the
parasite or its offspring. Although the alteration of host behavior by parasites is a widespread …

Insects that use ephemeral resources must rapidly digest nutrients and simultaneously
protect them from competitors. Here we use burying beetles (Nicrophorus vespilloides) …

The parasitoid emerald jewel wasp Ampulex compressa induces a compliant state of
hypokinesia in its host, the American cockroach Periplaneta americana through direct …

Venoms from several arthropods are recognized as useful sources of bioactive substances,
such as peptides, acylpolyamines, and alkaloids, which show a wide range of …

Locomotor deficits frequently accompany aging in animals. These deficits are often caused
by degeneration in the nervous and musculoskeletal systems. Insects are an excellent …

In this article, we provide direct evidence for injection of venom by a wasp into the central
nervous system of its cockroach prey. Venomous predators use neurotoxins that generally …

Background The parasitoid Jewel Wasp hunts cockroaches to serve as a live food supply for
its offspring. The wasp stings the cockroach in the head and delivers a cocktail of …

Some ichneumonid wasps induce modifications in the web building behavior of their spider
hosts to produce resistant “cocoon” webs. These structures hold and protect the wasp's …

The sting of the parasitoid wasp Ampulex compressa is unusual, as it induces a transient
paralysis of the front legs followed by grooming behavior and then by a long-term …
