Indeed, this predilection for specialization may well be the principal factor involved in the tremendous diversification of this group of organisms (Ehrlich and Raven

Decision Theory and Decision Behaviour ecological circumstance is built into current patterns of host-plant utilization, we have attempted to speculate how and why insects eat particular host-plant species using phylogenetic, geographic, and life history relationships among extant insect taxa. These approaches have produced some robust

Research in agricultural systems indicates that a major cause of this structure is genetic variation in resistance among individual hos

Igor Aleksander,Henri Farreny,Malik Ghallablly, genetic structure has been regarded as an interdemic phenomenon (Wright 1931). In that view, species are subdivided into some number of more or less randomly mating subunits, or demes, that are connected to one another by some pattern of gene flow. An individual is characterized by its genotype
