Also, the study revealed a highly variation in the glucose contents of cheese which decreased with increasing the number of A. siro infestation from 200  to 300 mites.The obtained data showed that there were significant differences between the effect of mites number (100, 200 and 300 mites) and the cheese lipids contents. When the number of mites infestation was 100 mites, the differences in the lipids contents was not clearly observed when compared with control (without infestation); but the significant difference in the lipids was observed when the number of mites was 200. However, the study also denoted that when the numbers of A. siro infestation on cheese increased from 100–300 mites, the contents of cheese amino acids is increased.  }, keywords = {}, url = {https://jppp.journals.ekb.eg/article_53034.html}, eprint = {https://jppp.journals.ekb.eg/article_53034_e0446eba99039d8795863851e452fe70.pdf} } @article { author = {Abd El-Salam, M. and Somaa, H. and Khattab, M. and Abdel Aly, Amal}, title = {EVALUATION OF SOME COTTON VARIETIES TO PIERCING SUCKING INSECTS INFESTATION}, journal = {Journal of Plant Protection and Pathology}, volume = {6}, number = {1}, pages = {9-17}, year = {2015}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3677}, eissn = {2090-3758}, doi = {10.21608/jppp.2015.53043}, abstract = {The present investigation aims to determine the susceptibility of six  cotton varieties to piercing sucking insects infestation and relative between yield and yield components with   infestation of sucking insect.
