Direct injection of venom by a predatory wasp into cockroach brain.
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 act at the neuromuscular junction, resulting in different types of prey paralysis. The sting of the parasitoid wasp Ampulex compressa is unusual, as it induces grooming behavior, followed by a long-term lethargic st...

After being stung the cockroach grooms almost continuously for approximately 30 min, performing all the normal components of grooming behavior.

متن کاملWasp venom blocks central cholinergic synapses to induce transient paralysis in cockroach prey.
The parasitoid wasp Ampulex compressa induces a set of unique behavioral effects upon stinging its prey, the cockroach. It stings into the first thoracic segment inducing 2 to 3 min of transient flaccid paralysis of the front legs. This facilitates a second sting in the cockroach's head that induces 30 min of excessive grooming followed by a 2 to 5-week long lethargic state. In the present stud...
متن کاملWasp venom allergy: effect of anti-IgE antibody on wasp venom anaphylaxis in a mouse model.
BACKGROUND Although anti-IgE antibody (Ab) therapy was recently shown to be effective in patients with bronchial asthma, no study has reported the effect of IgE therapy in the prevention of wasp venom anaphylaxis. In this study, we used a mouse model of wasp venom allergy to investigate the effect of anti-IgE Ab on wasp venom anaphylaxis. METHODS We developed a mouse model of wasp venom aller...
