Influence of host plant changing on the development of Tetranychus urticas Koch (Acari, Tetranychidae): consequence of mite infestation in Citrus fields. Changes of hosts in T. urticae is associated with notorious lost of reproduction potentialities. At 25°C, the fecundity of females which are always reared on Solanum nigram (75.7 eggs) fell to 1.07 eggs when they were reared on Citrus . It is the same for the longevity of females in this mite. The females permanently feeding on Citrus have a longevity of 16.9 days compared with only 9 days in females from Solanum nigrum that were transferred to Citrus . Similar changes operated at 20°C produce the same results. The practical consequences of these experiences on the swarming of mites in the field of Citrus were analysed.
