title: Preliminary isolation of male-inhibitory pheromone of the spiderSchizocosa ocreata (Araneae, Lycosidae).
abstract: Compounds with pheromone activity were extracted from maleSchizocosa ocreata silk using methanol as the solvent. Behavioral data suggest that these compounds mediate agonistic encounters among male spiders. Preliminary chemical analyses indicate that the pheromones are low-molecular-weight lipids, one being slightly polar, the other nonpolar.
