The various plant characteristics, insect characteristics, and environmental factors influencing post-ingestive suitability for the growth of immature insects has been reviewed recently (Scriber and Slansky, 1981). The nutritional ecology of insects involves basic nutrition (requirement

Aggregation may be viewed as the end result of movement reactions that reduce the distance between individuals in their environment. Such clustering may be brought about by a com

The same compounds may also exchange information between different species, acting as allomones or kairomones.

The various mathematical models discussed here have been used to describe the dispersion of pheromones in still air (Bossert and Wilson, 1963; Mankin ., 1980a) or moving air (Wright, 1958; Bossert and Wilson,
