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.

The incidence of sucking pests and bollworms was recorded on eight varieties of Asiatic cotton, Gossypium arboreum (LD 272, LD 290, LD 299, LD 323, LD 326, LD 327 and LD 230) during 1985 and 1986. The sucking pests, cotton jassid (Amrasca biguttul...

Behavioral thermoregulation can impact foraging behavior, increase predation risk, and impart physiological costs. Locating thermally favorable microsites efficiently would minimize these constraints. Emitted thermal radiation is a direct indicato...

The oxygen uptake and a...
