(一)荔枝銹蜱(Eriohyes litchii Keifer)俗稱荔枝銹誘壁蝨，為本省中南部荔枝的一大害蟲，荔枝葉片被寄生後，收縮、腫賬，故有荔枝縮葉病及腫葉病等別稱。
(四)在六種供試藥劑中，以克氯苯1,000倍液之效果最優，次為可濕性硫黃粉300倍液，再次為Pestan 1,000倍液。其餘三種儀次為可利生1,000倍液，大生Z-78 1,000倍液及鐵地旺1,000倍液。
1. Erinose mite of litchi, Eriophyes litchil Keifer, is one of the most serious pests in centro-southern Taiwan. As an affected leaf sometimes contracting and swelling, many orchardists mistake the erinose for a kind of diseases and name it leaf-dwarf or leaf-hypertrophy of litchi.
2. In our former works in 1950-1952, the best result of control is given by Limesulphur at 0.3-0.5 Be’ but owing to its phytotoxicity, it is unsatisfactory to apply.
3. Control of erinose mite of litchi with low toxic chemicals has been carried out in Jan.-Mar., 1966, at Zen-mei village, Niau-song country, Kaohsiung district.
4. Among 6 kinds of chemicals, the best result was shown by Chlorobenzilate at 1:1,000. Sultan (wettable sulphur) at 1:300 and Pestan at 1:1,000 were also very excellent. The remained 3 kinds of chemicals, arranged according to the order of the effectiveness were Karathane, Dithane Z-78 and Tedion all that were diluted at the ratio of 1:1,000.
5. Tedion was not efficient, for which has been used many times throughout the years by orchardists, and thus might gradually cause the mite in getting resistance.
