Abstract

Suscep < /span>tibility ofthree varieties of barely plants (Giza-123, Giza-2000 and Giza-132) were evaluated toward infestation by aphids and leafhoppers. Also, the effect of potassium fertilization on the chemical content and anatomical compositions in relation to homopterous insect populationat Diarb Nigm locality Sharkia Governorate during 2013/14 and 2014/15 growing seasons. Results showed that Giza-123 is the lowest variety in terms of chemical content (total protein and carbohydrates content) and also found therewas a shortage in the thickness of the anatomical traits measured. These results led to that Giza-123 is considered as the sensitive variety toward infestation by insects with the lowest crop yield. On contrary, Giza-132 records the longest thickness cellwall, lowest infestation insects and the highest crop yield. Chemical analysis showed a positive relationship between total protein, carbohydrate contents and aphids, leafhoppers infestation in different barley varieties, while reverse relationship between pH values and insect infestation. Potassium fertilization by 100 kg potassium sulfate/feddan greatly increased the thickness of the anatomical traits [cuticle and upper epidermis thick. (μ), cuticle and lower epidermis thick. (μ), mesophyll tissue thick.(μ)lamina thick. (μ)] It is noted that, increasing the thickness of upper and/or lower epidermis and their cuticle layers decreased the population density of piercing suckinginsects in blade leaf and increasing mesophyll tissue thickness improve the photosynthesis process which lead to decreasing the adverse effect of insects. which associated with lowering the number of piercing -sucking insects. Thus, potassium fertilization by 100 kg potassium sulfate/feddan is recommended in the integrated pest management control (IPM) on barely plants.
