Venoms of the Hymenoptera: biochemical, pharmacological and behavioural aspects.
Venoms of the Hymenoptera: Biochemical, Pharmacological, and Behavioral Aspects contains papers that deals with the study of the venoms and toxins produced by insects belonging to the order of the

TLDR
Kinins are neurotoxic components of wasp and ant venoms, causing in the insect CNS a presynaptic block of the cholinergic transmission by means of an irreversible depletion, probably caused by a non-competitive inhibition of choline uptake.
Pharmacological characterization and chemical fractionation of the venom of the ponerine ant, Paraponera clavata (F.).
1. The neurotoxic action of the venom of the ponerine ant, Paraponera clavata, was studied using a cascade of mammalian smooth muscle preparations and a preparation for investigating transmission
2 – Morphology of the Venom Apparatus
TLDR
The embedding technique, discovered by Swammerdam, made possible his extensive studies on the chitinous parts of the sting of bees and wasps, and the paucity of information on solitary Aculeata is shown.
Poneratoxin, a novel peptide neurotoxin from the venom of the ant, Paraponera clavata.
TLDR
Synthetic poneratoxin is a strong, but very slowly acting agonist for smooth muscles and its blocks synaptic transmission in the insect CNS in a concentration-dependent manner and depolarizes giant interneurons.
Change in behaviour of the cockroach, Periplaneta americana, after being stung by the sphecid wasp Ampulex compressa
TLDR
Undisturbed cockroaches seem to be lethargic, and if stimulated they are able to run with speeds that equal that of control animals.
Threonine6-bradykinin in the venom of the wasp Colpa interrupta (F.) presynaptically blocks nicotinic synaptic transmission in the insect CNS.
TLDR
The venom of the solitary scoliid wasp Colpa interrupta shows a kinin-activity, when tested on a cascade of mammalian smooth muscle preparations, and, in addition, a contraction of the rat colon, and synthetic Thr-bradykinin causes irreversible presynaptic activation-induced block of transmission in the insect CNS.

TLDR
Poneratoxin, a 25 amino acid residue polypeptide, isolated from an ant venom, is the first described hymenopteran neurotoxin affecting excitability of nerve and muscle fibres by changing the kinetics of the voltage-dependent sodium channel.
The venom of Ampulex compressa--effects on behaviour and synaptic transmission of cockroaches.
TLDR
A solitary wasp Ampulex compressa stings a cockroach, Periplaneta americana, twice, and the first sting into the ventral thorax results in a transient paralysis, which gradually Results in a permanent deactivation.
