PRELIMINARY OBSERVATIONS ON ACARI OF THE PEACH TREE IN TUSCANY
The following phytophagous mites were found: two species of Eriophyoidea, three of Tetranychidae and occasional specimens of one species of Tenuipalpidae. The predaceous mites were: various species of Phytoseiidae, and few specimens of one species of Stigmaeidae. Of the groups with non-specialised feeding habits different species of Tydeidae and of Tarsonemidae were collected.
The relationship between the different groups of Acari is shown and correlated with the different cultural conditions of the peach orchards under consideration.
