Influence des conditions climateriques sur le developpement des insectes et champignons parasites des cultures

The propagation of Phylloxera vastatrix is favored by hot dry summers which desiccate the surface soil and induce swarming of the young. In the vineyards of central Europe a marked increase of mildew (Peronospora viticola) may be expected in wet yrs., especially if a humid atmosphere prevails during the period when the vines are making the most rapid growth. The danger is considerably lessened if the mean temp. remains rather low, and is exaggerated if the temp. is high, especially if sunlight is intermittent. In dry hot years only slight injury may be feared from the vine worm (Cochlys ambiguella) especially if the heat and drought coincide with the oviposition and hatching of the young larvae (end of May to the first of June, and end of July to the first of August). In humid years the larvae cause much damage especially if blossoming is unduly prolonged. Coniothyrium diplodiella causes particular damage when hail storms strike the vineyards in July and August. Later the danger is less, as a high sugar content in the grape restricts the abundant development of fungous mycelium. Vineyards on low-lying land suffer most.
