A field experiment was carried out during 2017/18 and 2018/19 seasons at the Agronomy Department Experimental Farm, Agriculture Faculty, Assiut University, to study the effect of foliar spray by some Nano micro-nutrients on production of three bread wheat cultivars. The experiment was laid out in randomized complete block design (RCBD) using strip plot arrangement with three replications. Foliar spray with tap water (solvent as a control) and Foliar spray with Fe, Mn, Zn, Fe+Mn, Fe+Zn, Mn+Zn and Fe+Mn+Zn in Nano form at 200 ppm were allocated horizontally, while bread wheat cultivars (Sids-1, Sids-12 and Gemmeaza-11) were arranged vertically. The obtained results show that the foliar spray treatment by some micro-nutrients Nano-particles had a significant effect on plant height, kernels number spike-1 , 1000 kernel weight, kernel weight spike-1 and grain yield in both seasons. Thus, wheat plants which were sprayed by Fe+Mn+Zn produced the highest mean values of the most previous traits. Furthermore the studied cultivars had a significant effect on all studied traits. In addition, Gemmeaza-11 cultivar produced the highest mean values of most studied traits in the two growing seasons. Here too, the interaction between some micro-nutrients Nano-particles and bread wheat cultivars had a highly significant (P ≤ 0.01) and significant (P ≤ 0.05) influence on grain yield in the first and second seasons respectively. Thus, the highest mean values of grain yield (26.80 and 26.95 ardab fed.-1 in the tow respective seasons) were obtained from Gemmeaza11 cultivar which was sprayed by Fe+Mn+Zn Nano-particles in both seasons.

A complementary description of Panonychus caricae Hatzinikolis, 1984, is presented based on the morphology of adult female and male individuals collected from fig trees (Ficus sp., Moraceae) in Greece. Morphological differences between Panonychus caricae and two closely related species, Panonychus ulmi (Koch, 1836) and Panonychus. hadzhibejliae (Reck, 1947), are discussed. Panonychus caricae can be separated from two other Panonychus species using the length of the female dorsal setae in combination with the ratio between the length of female dorsal opisthosomal setae f2 and h1, and the ratio between the length of dorsal setae sc1 and h1. A phylogenetic maximum likelihood tree was constructed based on the cytochrome c oxidase subunit I (COI) gene of mitochondrial DNA (mtDNA) from 10 species of the subgenus Panonychus s.str. (including the re-described species P. caricae) and the only two species of the subgenus Sasanychus. The phylogenetic tree indicates that these 12 species are clearly separated from each other. The two subgenera, Panonychus s.str. and Sasanychus, comprise strongly supported monophyletic clades with 98% bootstrap values. The convergence of molecular and morphological data (dorsal setae set on tubercles or not, number of tactile setae on tibiae I and II, and patterns of the dorsocentral striae) suggests that Sasanychus should not be classified under the genus Panonychus. Consequently, molecular and morphological evidence supports the resurrection of the genus Sasanychus, which contains two species, S. akitanus (Ehara) and S. pusillus Ehara & Gotoh, as distinct from Panonychus. A key to the world species of Panonychus and Sasanychus is also provided.
