Larvae paralysed by Habrobracon venom remain motionless for several weeks due to general inhibition of neuromuscular transmissions. Pulsations of dorsal vessel are myogenic and the heartbeat of the paralysed larvae can be monitored in vivo without intervention of the neurogenic muscular systems. One picture shows paralysed larva during a touch-free, optocardiographic recording of heartbeat, which resulted in electrocardiographic record exemplified by the second illustration. Using this method, a motionless insect larva can be used for testing of new cardioactive preparations.Using this method, a motionless insect larva can be used for inexpensive screening of cardioactive pharmacological preparations.
