An experiment was carried out to study the effect of some agricultural and chemical treatments on two serious insects i.e. leaf miner, Tuta asoluta (Meyrick), and the cotton whitefly Bemisia tabaci (Genn.) that infest tomato plants, as well as the influence on the growth, fruit yield and its quality were evaluated. The trail was carried out in a sandy soil at Amoun Agricultural Association, Eltal El Kabier, Ismailia Governorate, Egypt during two autumn seasons of 2013 and 2014. The experiment included 7 treatments as follows: covering tomato plants with agryl, white and green net as a row covering tunnels, dusting with Sulfur (repellent the insect) as the safety material for human and environmental comparing chemical pesticides i.e. Actara using it as foliar spraying or soil drench and

The present experiments were conducted to study the effect of different solanaceous host plants on the population density of the leafhoppers and planthoppers according to the morphological diversity of host surface and phytochemical composition on the preference behaviour of the insect pests. The leafhoppers, Empoasca decipiens and Empoasca decedens preferred eggplant as a host plant followed by tomato and pepper by using the three methods (leaf sample, yellow sticky traps, sweep net) during the two seasons. Meanwhile, Cicadulina chinai preferred tomato followed by eggplant and pepper by using the different methods. While, Balcutha hortensis preferred pepper followed by eggplant and tomato. On the other hand, the planthoppers, Sogatella futcifera preferred eggplant followed by pepper and tomato. Statistical analysis revealed that highly significant differences were recorded between the three host plants during the two seasons according to the average number of different leafhoppers and planthoppers by using the three sampling methods. The insect population varied among leaf surface morphological characters. The Scanning Electron Microscope pictures revealed that, the trichome type was nonglandular in eggplant and tomato, while in pepper was hairiness. Population density exhibited significantly of trichome length on eggplant, whereas had less significantly on tomato leaves with higher hair density. Peppers, with no trichome had the lowest population of insect. Depending on the analysis of phytochemical composition of plant leaves, a highly positive correlated leafhopper and plant hoppers with higher ratios was found for the total protein, total nitrogen, α-esterase, βesterase and Glutathione Stransferase (GST).

The experiment was conducted in the fall growing season of 2013 at farmer field in Badrashin province, Giza Governorate. The present study is to investigate and determines the suitable area (size), heights and direction positions of the yellow sticky traps to utilize those factors as new tools while implement the Integrated Pest Management strategy. Statistical analysis was showed presence highly significant differences between the tested trap sizes .The Data indicated that , the tested trap sizes can be arranged descending as follow: 200 >160 >80 >40> 20 Cm² in both tomato and cabbage fields. Moreover, the traps with 10 x 20 cm was captured the highest number of the Bemisia tabaci, adult, 38.33 and 566.27 (adults/trap) in tomato and cabbage crop, respectively. Data indicated that, there was an irreversible relationship between the number of the adults caught by the trap and its height. Where, the trap with 20 cm height above the ground surface recorded the highest captured whitefly adult per trap (63.33, 18.33 and 23.76 adult/trap in tomato, cabbage and uncultivated part (control), respectively). The results cleared that, the free hanging position type caught the highest number (164.87 adult/trap), but the reversible type caught the lowest number (19.07 adult/trap).The tested trap position arranged descending according its captures values as follow: free hanging> horizontal position> 45° angel towards north> vertical towards north > reversible trap, where its capture values were 164.87, 125.56, 109.30, 60.80 and 19.06 adult/trap. The trap with size 10X20 Cm², 20 Cm above the ground surface and free hanging recorded the highest capture of B. tabaci. The previous specification can be used to provide a clear picture about the population density of the whitefly in different crops at different period and use as implement tolls in the integrated pest management program.

Experiments were carried out to study the effect of rose (Rosa gallica) flowers color on the infestation of adults and nymphs of the rose aphid, Macrosiphum rosae (Linnaeus),(Aphididae, Hemeptera). Using five varieties of rose similar in the horticulture characters but different in the flowers color only. Carmen (red), Virginia (white), Freedom (yellow), Queen (blue) and Dream (pink) Experiments were done in two locations El-Orman Garden, Giza Governorate and International Garden, Cairo Governorate throughout 2015season. In both Governorates (Giza and Cairo), the infestation with the rose aphid adults began to appear on the 1 st February and recorded the activity peak during April then decreased until beginning of August. The flowers color of R. gallica may arrange for attracted the rose aphid adults, as follow: yellow, red, blue, pink and white, respectively. Statistical analysis showed that highly significant differences between the five flowers color (varieties) of R. gallica on the attraction of adults of the rose aphid, M. rosae. In the same trend, the infestation with the rose aphid nymphs began to appear on February and increase gradually lasting to the first pike in April, then the population began decreased until beginning of August. It can be arranging the flowers color of R. gallica for attract of the rose aphid (nymphs) as follows: yellow, red, blue, pink and white. Statistical analysis showed that highly significant differences between the five flowers color (varieties) of R. gallica on the attraction of M. rosae nymphs.
