ABSTRACT
Longitudinal research on the dynmics of Phytophagous mites and Phytoseiidae populations have shown that fluctuations of vine Tetranychidae are closely linked to anti-mildew programmes.
Studies on the biology and ecology of Kampimodromus aberrans (Oud.) has revealed that this species can both reduce high infestation levels and regulate phytophagous mites to a permanent low density owing to:
the rapid growth rate,
the high fecundity,
the good capacity of diffusion,
the high density levels during all the period of vegetation, due to its capacity to survive and reproduce even in the absence of prey,
the high overwintering population which occupies the leaves at the beginning of vegetation.
The strategy of the introduction of Phytoseiidae in the vineyards is reported.
