摘要:
Abstract.1. The augmentative release ofTrichogranznzaspecies for the biological control of graminaceous stalkborers is reviewed.2. Previous experiments indicate strong density dependence acting on the early larval stages of the sorghum stalkborer (Chilo partellus). These data are described by a simple model for density dependence, whose properties are briefly described.3. The effects upon the total mortality of different levels of egg parasitism are discussed when combined with density dependent larval losses that vary from under‐ to over‐compensat

摘要:
Abstract.1. Membracid species richness declines with increasing latitude in the Western hemisphere but begins to increase again in temperate regions. In northern latitudes this transition occurs in the highlands of Mexico and is the result of the emergence of a new tribe and greater host specialization.2. The relationship between number of species per genus and latitude is parabolic.3. We suggest the low number of species per genus in tropical regions may be due to the lack of host specialization and reduced coordination of life history with host phenology.
