Three soil types were selected: sandy clay, clay loam and loam and for each type six dumping depths were tested (3, 5, 7, 10, 15 and 20 cm).The results showed that the soil type had a significant effect on the adults emergence rate, and the highest rate was recorded for the sandy clay soil, when using the last larval instars (pre-pupae) and pupal stages, and reached 55.28 and 51.66%, respectively. The results also showed that the soil type and dumping depth together have a significant effect on the adults' emergence rate of the Mediterranean fruit fly. The sandy clay soil and the two depths, 5 and 7 cm, gave the highest emergence rate which was 73.3 and 71.67%, respectively, when using the last larval instar. Whereas, the clay loam soil gave at 3 and 5 cm soil depths a 70% emergence rate for both dumping levels. The results also showed that the two soil types sandy clay and loam showed that the emergence of adults continued even at 20 cm depth. The results obtained in this research can be incorporated to the practices used for the integrated management of the Mediterranean fruit fly C. capitata.

In the sugar diet, the following sugar sources were used: sucrose and yeast, glucose, fructose, sucrose, honey solution, and the honeydew obtained from the black scale olive insect Saissetia oleae and Euphyllura olivina, and water as control. In the protein diet, the amino acids tryptophan, phenylalanine and proline were used, with a mixture of them and distilled water as control. The results obtained showed differences in the effect of sugar type on the life span of both males and females, and the females' life span were longer than the males' life span in all tested groups, suggesting that the female's food requirements were higher than that of the males to provide energy for maturation and laying eggs. Results obtained also showed that P. concolor females fed on sucrose had lower average life span compared to other tested sugars and solid food. The protein feeding of the P. concolor parasitoid is very important because the females depend on the protein nutrition of the flowers to complete their sexual maturity. Nutrients such as proteins, amino acids and vitamins are also important for the activity and effectiveness of the insect parasitoids .

In some instances, annual economic yield loss due to this disease was estimated at 80%. Currently, pesticide applications are used for the management of early blight disease due to the lack of resistant cultivars. The effect of treatment of the susceptible tomato cultivar Super Marmond with three insecticides (Diazinon, Match® 050 EC and Vertimec®) was evaluated under laboratory and greenhouse conditions. In vitro assay showed that the pesticide Vertimec® (at a concentration of 300 ppm) was the most effective against A. solani with mycelial growth inhibition above 93%, inhibition of fungal sporulation to 0.26x103 spores/ml, and spore germination inhibition of 98.79%. In addition, there was a reduction in A. solani spores and their dry weight (0.0144 mg) in the presence of Vertimec®. In greenhouse experiments, when Vertimec® was used curatively on tomato leaves against A. solani, it lowered significantly disease severity (20.33%). The effect of this insecticide was not limited only to the protection of tomato plants but it also improved their growth by increasing the tomato shoot fresh and dry weights (21.94 g and 3.85 g, respectively) as well as the root fresh and dry weight (3.84 g and 0.89 g, respectively). Based on the results obtained, it can be concluded that Vertimec® could be used for early blight management when the tomato crop is also infested with insect pests.

The aim of this study was to determine the threshold temperature and calculate the heat units needed for the development time of the duration of this mite stage. Different incubation temperatures (10 15, 20, 25, 30, 35, and 40±2°C), relative humidity (50-60±5%), and light:darkness period of 16: 8 hours were applied to rear this mite on the lower surface of the newly grown grape leaves. The results showed that the development time of the egg, larva, protonymph, and deutonymph (active, quiescent, active + quiescent) at temperatures 15, 20, 25, 30, and 35°C were decreased gradually with temperature increase. Furthermore, the development time of the eggs incubation period was 15.3, 4.98 days and the larva (active + quiescent) were 15.1, 4.43 days, and the protonymph (active + quiescent) was 14.4, 3.48 days and of the deutonymph (active + quiescent) was 15.6, 5.58 days for the effect of 15 and 35°C. Additionally, the development time from egg to adult was 60.00 and 18.26 days at 15 and 35°C, respectively. The threshold temperature was 6.73, 7.89, 9.38, 6.47 and 7.3 °C, respectively.

A genomic segment of OYVMV with a size of 750 was amplified using polymerase chain reaction (PCR) and a set of specific primers. By amplifying a 750 bp band on agarose gel, the field isolate tested was identified as a member of the genus Begomovirus, which was related to an Indian isolate of the same virus. The study included determining the efficacy of three biological factors: (A) a medicinal plant preparation from A. Paniculara, (H) a preparation from Lion's mushroom (H. erinaceus and (P) a preparation from P. florescence bacteria which has impact on virus infection, as well as determining the response of three okra varieties to virus infection. The use of the three combined factors (A+H+P) outperformed other treatments reducing virus infection rate of the Petra okra variety to 26.67 % and severity to 10.66 % as compared to 100% for the control. The findings showed that there were substantial variation in the peroxidase enzyme activity and chlorophyll content, with the A+H+P treatment producing 59.14 units/mg protein for the Petra variety and 40.81 Spad for the Hasnawi variety.

The results obtained showed that the male T. absoluta activity extended from late February to the end of the season in July. The highest density for males recorded in May was 207 and 213 males/trap in both seasons, respectively. The calculation of the cumulative degree-days showed that the insect has five generations with a thermal constant that reached in the first season: 516.95, 510.24, 512.2, 563.44, 565.94 DD for each generation, respectively, and in the second season 554.52, 533.06, 557.21, 502.55, 508.22 DD for each generation, respectively, without significant differences between the two seasons (x² = 6.02, p = 0.2 and x² = 4.94, p = 0.29). However, according to the model followed, a simplified table was proposed to calculate the cumulative degree-day instead of using mathematical models, based only on the daily maximum and minimum temperatures.
