✦ Synopsis

Sex pheromone activity from female medwonn beetles (Tenebrio molitor) may be extracted and quantified by fractional population response of virgin adult males, which attempt copulation with any pheromone-treated object. Extracts of mature males can be shown to elicit identical behavioral activity, although at lower individual concentration. Since response to the pheromone is sex-specific, its apparent production by both sexes of T . molitor is especially noteworthy. It has been shown that the presence of pheromone in males cannot be due to contamination by females.

Both pheromone production and the male response are undetectable in newlyemerged adults; both rise to their maximum extent within one week of eclosion.

## Abstract A thermal hysteresis producing antifreeze protein was isolated from larvae of the beetle, __Tenebrio molitor__. This is the first thermal hysteresis protein purified from an insect. The specific activity of the __Tenebrio__ antifreeze is somewhat greater than that of the fishes. The com

The effect of octopamine on the neuromuscular junction of the mealworm (Tenebrio rnolitor) was examined. Octopamine potentiated excitatory junctional potentials (EJPs) recorded intracellularly and extracellularly from ventral longitudinal muscle fibers. The potentiating action of octopamine was bloc
