This study was carried out to evaluate efficiency sticky traps on attraction Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) on strawberry plants Fragaria ananassa (L.) (Three strawberry varieties i.e. Sweet charli, Chandler and Festival) under glasshouse conditions at two locations (governorates), Nobariya (Behera governorate) and Perkash (Giza governorate) during season 2019/2020. This study contains three experiments; the first experiment aimed to evaluate the efficiency color of the sticky trap on attraction T. vaporariorum throughout comparison between four colors (yellow, red, white and blue). Results showed that the traps which have yellow color more efficiency on attractive T. vaporariorum than others which have (blue, red, and white) color, respectively. Second experiment aimed to evaluation efficiency height of the yellow sticky trap on attraction T. vaporariorum through comparison between four heights (2m, 1.5m, 1m and 0.5m) above the ground. Results showed that the trap which have 2m height above the ground more efficiency on attractive T. vaporariorum than others which have (1.5m, 1m and 0.5m) heights, respectively. Third experiment aimed to evaluation efficiency orientation of the yellow sticky trap on attraction T. vaporariorum through comparison between four orientations (North, South, East and West). Results showed that had no clearly effect of the trap orientation on attraction T. vaporariorum.

Two field experiments were conducted at El-Rod village at Sahl El-Houssinia, El-Sharkia governorate, (32°15' 00" N 30°50' 00" E), Egypt. The study investigated evaluations of different nitrogen fertilizers sources (calcium nitrate, ammonium sulphate and urea fertilizers) and rates (0, 47.6, 71.4 and 107 kg N/ha) alone or combined with bio-fertilizer (using bio-fertilization with Rhiobium radiobacter sp strain on improve nutrients available and contents in cowpea productivity and quality in newly reclaimed saline soil conditions during two summer seasons 2017 and 2018.  The studies treatments were disturbed among the experimental pelts in split design with six replicates. The obtained results cleared that the used ammonium sulphate fertilizer was increase effect with increasing rate in EC, pH, and available N, P, K , Fe, Mn and Zn content in soil. Moreover data recorded the applied 71.4 kg N /ha was increase of plant height, weight of 100 seeds, weight of pods (g/plant) , weight of seeds (g)/plant and seeds yield (ton ha-1) have been affected by inoculation with bio-fertilizer combined with nitrogen sources fertilizers  and different rates than other treatments. The highest values of N, P , K, Fe, Mn and Zn concentrations and uptake in seeds treated with ammonium sulphate at rate 71.4 kg N/ha than other treatments. The decrease of the soil salinity to increased content of cowpea plant of chlorophyll and protein, but increased salinity of the soil led to increase the content of the plant of proline. The application of ammonium sulphat at 30 kg N/fed combined with bio-fertilizer was improve soil properties and cowpea productivity and quality under saline soils conditions.

Application of the RAPD methods allowed to clearly characterization of isolates of Botrytis fabae and isolates of B. cinerea. Results from RAPD-PCR analysis indicate different groups. Clusters were related with groups based on conidial morphology, morphological characters of the isolates of Botrytis spp.

Haplothrips cottei and Bemisia tabaci This study was carried out to study the effect of infested carnation plants (Dianthus caryophyllus L.) by Carnation Thrips, Haplothrips cottei (Vuillet) (Thysanoptera: Thripidae) and Bemisia tabaci (Gennadius) on the quantity of annual production of carnation flowers under glasshouse conditions at three locations (governorates), International Garden (Cairo Governorate), El-Orman Garden, (Giza Governorate) and International Garden (Alexandria Governorate) during successive season 2018, 2019. Therefore, this study was divided into three parts, the first part studied population fluctuation of H. cottei and B. tabaci on the carnation plants during successive season. The second part studied the effect of infested carnation plants by the two insects on the quantity of annual production of carnation flowers at the three locations. And the third part studied the effect of insect infestation by the two insects on the internal components of carnation plants. Results obtained showed that the infestation by H. cottei reduced the quantity of annual production of carnation flowers after picking more the infestation by B. tabaci compared to control (which non infested by the same insects). Also, results showed that the infestation by H. cottei reduced total sugar and total protein as the infested carnation flowers more than the infestation by B. tabaci compared to control.
