We are indebted to the late Dr. S. Blondheim and to Y. Peretz for many hours of collaborating in field work; to Dr. B. Shalmon who participated both in collection trips and in primary analysis of species distributions; to Dr. D.R. Ragge for lively discussions, guidance, and hospitality during several visits to the Natural History Museum (London), and to Dr. T.J. Cohn of the University of Michigan, Ann Arbor, for lively discussions and many editorial suggestions. This study was supported in part by a grant from the Fauna Palaestina Committee of the Israel Academy of Sciences and Humanities to M.P. Pener and by a two-month Researchers Exchange Grant from the Israel Academy of Sciences and The Royal Entomological Society London, toY. Ayal during the summer of 1987. This is publication No. 274 of the Mitrani Center for Desert Ecology.

N2 - Long-horned bushcrickets (Tettigoniidae) have been studied intensively in Israel for four decades. Forty-two species belonging to twenty-two genera have been recorded. This article reviews their biology and analyzes the geographical distribution and the species associations with plant communities of the five phytogeographical provinces represented in Israel. The majority of the species are associated with the Mediterranean and Irano-Turanian flora, with a few species each associated with the Tragacant, Saharo-Sindian, and Ethiopian flora. A high proportion (about 50%) of endemism, associated with a high proportion of brachypterous species, was found in the first three groups but not in the last two groups. Despite a general association with specific plant communities, no distinct relation between species distribution and precipitation levels was found. However, within the Mediterranean and Irano-Turanian groups, there is a distinct segregation of species with similar morphology between bush-forest and shrub-grassland habitats. It is suggested that 'apparent competition' (reciprocal negative interactions between species due to shared predators) may serve as the mechanism that drives this habitat segregation.
