Assuming that the size of ungulate virginopar bean lice, Aphis fabae Scop., A more appropriate parameter for antibiotic effects of their host plants than their daughter production or lifespan, will examine the factors that could influence larval growth. The size of the imagines and the extent and sequence of their offspring production are closely related to the nutritional conditions under which mothers live during their larval and imaginal phases. The development speed increases from 5 ° to 30 ° - slower - but the growth only up to 14 °; Higher temperatures increasingly result in smaller images. The imaginal size achieved by lice on punched leaf discs decreases with decreasing diameter or with increasing population density. On growing leaves (in situ) the bigger the imaginings, the greater the percentage increase in leaf area during postembryonic development. Slicing and rooting of primary leaves almost do not affect the size of the bean lice raised on them in the Schlanstedter field crop, whereas in Rastatter they give larger or smaller adults than in intact plants. The cause of all these growth reactions of bean lice is the vigor, especially the level of the amino acid level in the substrate. The ecological consequences for host change and resistance phenomena are discussed. give back as small adults as on intact plants.
