International Allelopathy Society has redefined Allelopathy as any process involving secondary metabolities produced by plants, algae, bacteria, fungi and viruses that influences the growth and development of agricultural and biological system; a study of the functions of secondary metabolities, their significance in biological organization, their evolutionary origin and elucidation of the mechanisms involving plant-plant, plant-microorganisms, plant-virus, plant-insect, plant-soil-plant interactions.

Using Data

The evolutionary origin of workerless parasitic ants parasitizing colonies ofLeptothorax(s.str.) is investigated using data on morphology, chromosome number, and allozyme phenotype of both social parasites and their hosts. Of the three previously proposed pathways, the evolution of workerless parasites from guest ants or slave-makers is unlikely, at least according to a phenogram obtained by UPGMA clustering of Nei's similarities based on seven enzymes, lntraspecific evolution of the workerless parasitesDoronomyrmex goesswaldi, D. kutteri, andD. pacisfrom their common host,Leptothorax acervorumcannot be excluded with the present data. The workerless parasiteL. paraxenus, however, clearly differs from its host,L.cf.canadensis, in morphology and biochemistry, and most probably did not evolve from the latter species. It is proposed to synonymizeDoronomyrmexunderLeptothorax(s.str.).
