Samplings of S. syriacus and C. undecimpunctata were carried out in Mansoura district, Dakahlia Governorate during 2008 and 2009 seasons. We examined several types of yellow sticky cards (vertically oriented cylinder, vertically oriented, two-sided traps and vertically oriented, one-sided traps) and sweep-net thin indirectly measured adult abundance based on activity and visual examination and whole-plant methods as two direct count sampling methods based on the census of adult on or from the plant.
The count of predator, S. syriacus was highly significantly effect by sampling methods. Sweep-net count more significant adult of S. syriacus than the other sampling methods during 2008 and 2009 seasons. Furthermore, in 2008 season, there were no significant notes between one sided sticky trap and whole-plant. In addition, there was no significant between cylinder sticky trap and two-sided sticky trap. In 2009 season, there was no significant between cylinder sticky trap, one sided sticky trap, and visual examination.
The relative variation of the sweep-net and one-sided sticky trap methods were significantly less than the other methods for sampling S. syriacus. Therefore, it is the optimum sampling methods and indicated greater precision for sampling S. syriacus. Sweep-net recorded the highest RNP compared with the other sampling methods. This indicated thin the sweep-net is the greater sampling efficiency.
The count of C. undecimpunctata was highly significantly effect by sampling methods in 2008 and 2009 seasons. Visual examination count more insects than sweep-net and whole-plant during 2008 and 2009 seasons. Visual examination had the lowest associated RV value in the first and second seasons (10.90 and 9.61, respectively). Visual examination had the highest calculated RNP value (most efficient) compared with all other sampling methods in the first and second seasons.

Interaction between root-knot nematode, Meloidogyne incognita alone and in combination with the bacterium, Ralstonia solanacearum were evaluated on the growth of potato plants cvs. Diamant and Spunta,nematode reproduction and bacteria as well under greenhouse conditions. Results showed that potato cv. Spunta was highly susceptible to bacterial wilt disease than cv. Diamant. The possible combinations of M. incognita and R. solanacearum revealed that potato plants inoculated with M. incognita 10 days prior to bacterial pathogen’s inoculation showed higher bacterial wilt disease rating than those inoculated with both pathogens simultaneously with values of 3.95 and 3.45, respectively. The higher nematode galling index was noted on potato plants cv. Diamant than cv. Spunta with values of 2.32 and 1.92, respectively. Results also showed that plants receiving nematodes with bacteria added at the same time, the highest injury of nematode accompanied by the highest rate of build-up that recorded to be 30.83 and 22.15 for potato cvs,Diamant and Spunta, followed by the combination with R. solanacearum 10 days after nematode inoculation that was recorded to be 26.78 and 20.35 for the same potato cultivars, respectively. Moreover, there was a significant reduction in both shoot and root fresh weights of the two tested cultivars infected with either pathogen alone or together.

Sampling of Bemisia spp. and M. cunctans was carried out at Mansoura district, Dakahlia Governorate during 2008 and 2009 seasons. We examined several types of yellow sticky cards (vertically oriented cylinder, vertically oriented two-sided traps and vertically oriented, one-sided traps), three colored of water pan traps (yellow, blue and red), the plastic cup trap (CC trap), sweep-net that indirectly measured adult abundance based on activity and visual examination (leave-turn) and black pan methods as two direct count sampling methods based on the census of adults on or from the plant.
The count of Bemisia spp. was highly significantly effect by sampling methods. Among the sampling methods, cylinder sticky traps was caught the most adults of whitefly during the two seasons. Furthermore, there were no significant differences between one sided sticky traps, CC traps, black pan, vacuum sampler, whole-plant, and leaf-turn method. In addition, there were no significant differences between cylinder sticky and two-sided traps. The black pan had the lowest associated relative variation (RV) value in both seasons. Whereas, the whole-plant had the highest calculated RV value in the first season. While in the second season, the cylinder sticky traps had the highest calculated RV value. The black pan method had the highest calculated RNP value (most efficient) compared with all other sampling methods. Whereas, the vacuum sampler had lowest associated RNV value in both seasons.

Evaluation of DiTera a commercial formulation of Myrothecium verrucaria against Meloidogyne javanica was examined in-vitro for mortality, greenhouse as well as field trials on tomato and grape using various rates and method of applications. In-vitro test revealed a positive correlation between M. javanica J2 mortality and biocide compound rate and concentration at various exposure periods. Larval mortality significantly increased with the increase of rates and concentrations from 10 up to 30%, as well, whereas, a slightly increase in M. javanica J2 mortalitywas insignificantly noticed according to the tested two temperatures. With respect to tomato greenhouse trial, all tested DiTera rates and type of applications obviously caused remarkable increase in tomato growth cv. Castle Rock. Among DiTera rates, treatment at 0.3 g / seedling ranked first in increasing percentage of fresh weight of the whole plant with values of 56.73, 41.70 and 77.32% for the three type of applications i.e. at planting, post planting and pre planting respectively. As the rates of DiTera increased from 0.1 up to 0.3 g/ seedling, the percentage increase values of such plant growth parameter increased from 21.26 to 41.70%; 36.6 to 56.73%; and 57.5 to 77.32% for post planting, at planting and pre- planting application, respectively. Similar trend was noticed for suppressing nematode parameters, where the pre-planting application ranked first with values of 85.2, 89.2 and 94.1%, for the rate of 0.1, 0.2 and 0.3 g/ seedling, respectively. Moreover, It is worthy to note that there was a positive correlation between the rate of nematode build-up and DiTera compound rates, whereas this nematode criterion recorded to be the least value (0.26) by oxamyl treatment. Meanwhile, in tomato field trial, the rate of 0.3 g/ tomato seedling significantly decreased the number of galls on tomato roots with reduction percentages of 85.8, 71.0 and 59.7% for the pre-, at- and post- planting applications, respectively. All tested DiTera rates along with application times reduced tested nematode parameters. Among the three application times, the pre-planting method of adding DiTera compound accomplished the highest reduction percentages of nematode population densities with values of 74.3, 82.2 and 85.2 for 0.1, 0.2 and 0.3 g /plant respectively. Regarding grape greenhouse and field trials, all tested DiTera applications i.e. 2 g/plant 4 , 5, and 6 times at one week interval in both greenhouse and field trials obviously showed protection performance in grape plants cv. Thompson against nematode infestation of M. javanica in terms of reduction percentages of tested nematode parameters on grape roots as well. Likewise, as the addition of 2 g/ plant raised from four up to six times at one week interval, nematode criteria significantly decreased. Plants receiving DiTera treatments six times accomplished the highest reduction percentages in nematode parameters followed by that of five times and then four times applications. Moreover, oxamyl treatment twice at one month interval surpassed all tested DiTera application in suppressing nematode population, number of galls and eggmasses in both trials.

The effect of different diets (Wheat flour, garlic , aniseed and Cumin) and gamma irradiation on the larval growth rate, the development and the reproduction of L. serricorne (F) were investigated. Newly hatched Larvae were irradiated by dosages 20, 40 and 60 Gy. There was variation of weight gain, feeding period and growth rate of Larvae according to the effect of type of food and the dosage of gamma ray. When larvae were fed on aniseed , the highest growth rate was recorded. There is an inverse relationship between, the larval growth rate and doses of gamma irradiation. Also the feeding period increased as the dose increased form 0 – 60 Gy in all types of diets.
Larval irradiation as newly hatched induced a reduction in percent pupation and adult emergence progressively as the dose was increased. The reduction reached maximum , when larvae were fed on garlic, while reached its minimum on aniseed. Fecundity , Fertility and longevity of the resulling adults were gradually reduced with the increase of the dose.

Department of Biological Control, Plant Protection Research Institute, Sakha, Egypt
The present investigation was achieved at Sakha Agricultural Research Station during 2008 and 2009 seasons to evaluate efficiency of the fungus Beauveria bassiana (Bals.) as a biological control agent in field applications against the European corn borer, Ostrinia nubilalis (Hub.) in corn fields (2008 season), the lowest concentration (2.5×107) induced 26.87% reduction, while 5×107 resulted 44.64% larval reduction, the highest concentration 1×108 conidia/ml resulted 58.23 % larval reduction.
Infested internodes were reduced in values ranging between 23.78% and 66.53 % at different B. bassiana concentrations. The highest concentration (1×108) reduced number of holes and number of broken tassels by 60.03 and 73.28 %, respectively.
In 2009 season, reductions were 60.88, 62.63, 47.80 and 64.85 % for larvae, infested internodes, holes and broken tassels, respectively when the highest concentration (1×108 conidia/ml) was applied.
Treated rice plots (2008 season) by B. bassiana against the rice stem borer, Chilo agamemnon (Bles.) reduced dead hearts by 20.29, 43.59 and 55.0 % fifteen days post treatment. More reduction in dead hearts were obtained 30 days after treatment; 24.23, 50.17 and 71.88 % at 2.5×107, 5×107 and 1×108 conidia/ml, respectively. Also, white heads were reduced, 30 days post treatment, by 34.87, 56.23 and 70.88 at 2.5×107, 5×107 and 1×108 conidia/ml, respectively.
In 2009 season, 30 days after applications, dead hearts were reduced by 26.48, 51.68 and 73.30, while white heads were reduced by 35.34, 62.26 and 72.04 % for 2.5×107, 5×107 and 1×108 conidia/ml, respectively. Thus, two sprays by the fungus at two concentrations could be applied to get sufficient reduction in reducing the infestation by O. nubilalis and C. agamemnon in maize and rice fields.
