The venom of the wasp Campsomeris sexmaculata (F.) blocks synaptic transmission in insect CNS



The venom of the wasp Campsomeris sexmaculata (F.) blocks synaptic transmission in insect CNS



Comparative Biochemistry and Physiology. C, Comparative Pharmacology and Toxicology 87(2): 283-286



1. The action of the venom of the wasp Campsomeris sexmaculata on the insect CNS has been studied using the cercal nerve-giant interneuron preparation of the sixth abdominal ganglion of the cockroach. 2. The venom blocks synaptic transmission either transiently (at low concentration) or for a long time (at higher concentration), and causes a permanent depolarization of the neuron with a delay. 3. The venom does not affect directly the axonal excitability.
