Two new mite species of the genus Caloglyphus Berlese, 1923 (Acari: Acaridae) are described and illustrated based on deutonymphal stages collected from mango orchards in Assiut, Upper Egypt. The new species, C. mangiferus sp. nov. and C. similares sp. nov., were extracted from soil samples under the mango trees. The new species are characterized by having a pair of short peduncles globosely setae situated dorsosublaterally on the idiosoma.

The mango spider mite, Oligonychus mangiferus (Rahman and Sapra) (Tetranychidae) and the mango bud mite, Aceria mangiferae Sayed (Eriophyidae) are serious pests of mango orchards in Egypt. The population dynamics of both species were studied on two mango cultivars (Zebda and Taimoor) under the natural climatic conditions of Assiut Governorate. Also, an annotated list was provided for the mite fauna inhabiting mango orchards during the present study and in previous Egyptian literature. The results showed that the population dynamics of both mite pests were affected by the ambient climatic conditions (temperature and relative humidity) and mango cultivar. The peak population of O. mangiferus was reported in October-November on leaves of both cultivars, while A. mangiferae was found regularly at almost all examined buds throughout the year. The checklist reported on 67 species belonging to 30 families and 52 genera. The predatory mites, Eucheyletia sp., Lepidocheyla gracilis Volgin (Cheyletidae) and Hemisarcoptes coccophagus Meyer (Hemisarcoptidae) were recorded for the first time in Egypt. Interestingly, the family Phytoseiidae represented the largest diversity of mites reported herein, with 10 species records. We anticipate that the results reported in the current study may encourage the establishment of control programs for these pests using phytoseiid mites.

This paper reports on ten species, in six genera, of soil-inhabiting mites of the family Laelapidae from Assiut Governorate, Egypt. The species Androlaelaps projecta Furman, 1972, Gaeolaelaps mirzakhaniae Kazemi & Khalesi, 2018, G. nolli (Karg, 1962), Hypoaspisella asperatus (Berlese, 1904a) comb. nov., Laelaspis calidus Berlese, 1924 and Ololaelaps tasmanicus (Womersely, 1956) are recorded for the first time from Egypt. Supplementary descriptions of some species are presented to facilitate species delimitation. The males of Cosmolaelaps longus (Hafez, Elbadry & Nasr, 1982) and O. tasmanicus are described for the first time.

A new phytoseiid mite species, Amblyseius marunumus sp. n., is described and illustrated based on female and male specimens collected from Gunma, Japan. The new species belongs to the americanus species-group, due to the presence of setae J2 and Z1, and having setae z4 longer than z2. Amblyseius marunumus sp. n. is morphologically close to A. yadongensis Wu, but differs conspicuously in the length of the dorsal idiosomal setae z4, r3, S2, S5 and the shape of spermatheca.

A new species of flat mite, Cenopalpus umbellatus sp. nov. (Acari: Trombidiformes: Tenuipalpidae) is described and illustrated based on females, males, deutonymphs, protonymphs and larvae. The morphological ontogeny in idiosomal and leg chaetotaxy is briefly described for all stages. Mite specimens were collected from the leaves of Rhaphiolepis indica var. umbellata Makino (Rosaceae), an evergreen shrub native to Japan. An identification key to the world species of Cenopalpus is also provided.

Thirty samples (10 raw milk, 10 yoghurt and 10 cheeses) were randomly collected from local markets in Assiutcity. All samples were chemically analyzed for acidity, fat, total nitrogen, soluble nitrogen, salt and ash contents, microbiologically for total counts of bacteria, molds & yeasts and for the incidence of coliform bacteria. The obtained results were (0.13-0.20), (0.63 –0.81) and (0.27-0.97) for titratable acidity, (3-7.3), (3.0-4.7) and (1.00-35.00) for fat contents, (0.47-0.60–), (0.70-0.83) and (2.05-3.7) for total nitrogen (TN%), (0.28-0.45), (0.011-0.029 ) and( 0.014-1.33 ) for soluble nitrogen ( SN%) , ( 0.17-0.29), ( 0.16-0.31) and (2.34 –9.56) for salt contents and ( 0.40 -1.05) , ( 0.70–0.89) and ( 2.5 –7.52) for ash contents of liquid raw milk, yoghurt and cheese samples respectively. microbiological analysis the total bacterial counts (TBC) were (2.25×105-5.25× 107), (4.9 ×105-7.25× 107) and ( 4.1 ×105-18.75× 107), molds & yeasts ( 1×102-45×102),( 1×102-40×102)and ( 1×102-17×102) for liquid raw milk, yoghurt and cheese samples respectively. The results also showed that, most of the investigated samples were free from coliform bacteria except for raw milk.
