Summary
An attempt is made to show why phytoseiid mites on citrus and avocado in southern California seem to be more effective predators of phytophagous mites than those on apple in southeastern England. It is suggested that this difference is caused both by factors inherent in the predator, such as its distribution, and by factors in its environment, such as the distribution of the prey and winter temperatures.
Sommaire
Une tentative faite afin de déterminer les causes pour lesquelles les acariens phytoseiides semblent être des prédateurs plus efficaces des acariens phytophages sur les Citrus et les Avocats du sud de la Californie, qu'ils le sont sur les pommiers dans le sud de l'Angleterre, suggère que cette différence est attribuable à la fois à des facteurs inhérents aux prédateurs, telle leur distribution, et à des facteurs du milieu, telles la distribution des proies et les températures hivernales.
