Olive and carnation absolutes are new forms extracted from the concrete produced after extraction of oil. Repellency and fumigation bioassays are of the best methods which used to evaluate the absolutes of olive and carnation against T. castaneum and R. dominica adults. Results obtained showed that the repellent and fumigant activities of carnation had the strongest effect to the two tested insects in comparison with that of olive. Moreover, the lowest concentration of carnation (5 ppm) achieved 50, 100% repellent activity compared to that of olive which caused zero and 35% after 24 h against T. castaneum and R. dominica, respectively. Additionally, the affection of oil increased with increasing of exposure period. However, the repellent of the two absolutes against the two insects started to decrease after 24 h post treatment. The time needed for oil to cause LT50 was also estimated at the highest concentration which achieved nearly 100 % mortality (449.95 mg/170 cm3) for both carnation and olive. Basedon LT 50 values the carnation oil was the premier compared to the olive with LT 50 values of 0.166, 0.01 and 0.688, 50.166 h against R. dominica and T. castaneum , respectively. Finally, the present study suggests application the absolute oils against stored product insects where they are very cheap, available and easy affordable and they may introduce the program of integrated pest management.

Two field experiments were carried out at Sidi Salem Directorate, Kafr EI-Sheikh Governorate, Egypt, during the two successive winter seasons of 2011/2012 and 201212013 to study the effect offour nitrogen fertilization rates (0, 37.5, 75 and 112.5 kg N/fed) and three phosphorous fertilization rates (0, 15 and 30 kg P2O5/fed) on the growth characters, yield, its component and some chemical properties of three bread wheat cultivars (Gemmeiza 9, Sakha 93 and Giza 168). The experimental design was split split plot design in four replications. The obvious results of this investigation can be summarized as follows: All traits of wheat under stUdy, i.e. No. of tillers/m2 , No. of spike/m2, plant height, spike length, No. of kernels/spike, 1000-kernel weight, kernels weigh/spike, straw yield/fed, grain yield/fed, biological yield/fed, harvest index, kernels nitrogen content (%) and grain protein yield/fed showed significantly increased by increasing nitrogen fertilizer rates, except kernels phosphorous content (%). Application of 112.5 kg N /fed significantly gave the maximum values of all traits. Increasing phosphorous fertilizer rates up to 30 Kg P2O5/fed significantly increased No. of tillers/m2, No. of spike/m2, plant height, spike length, straw yield/fed, grain yield/fed, biological yieldlfed and kernels phosphorous content (%) in the two seasons. While, No. of kernels/spike, 1000-kernel weight, kernels weight/spike, harvest index, kernels nitrogen content % and grain protein yield/fed were not affected by increasing phosphorous fertilizer rates. The results showed that wheat cultivars were significantly differed in all traits studied under study in the both seasons, except biological yield kg/fed, kernels nitrogen content (%) and kernels phosphorous content (%). Gemmeiza 9 cultivar significantly surpassed Sakha 93 and Giza 168 cultivars in plant height, spike length, 1000-kernel weight, kernels weight/spike, grain yield/fed, harvest index and kernels protein yield/fed in the both seasons, while, Sakha 93 recorded the highest values of No. of kernels/spike. Morever, Giza 168 surpassed the other two cultivars in No. of tillers/m2, No. of spike/m2 and straw yield/fed. The first order interactions between (112.5 kg N/fed X 30 Kg P2 O5/fed), (112.5 kg N/fed X Gemmeiza 9) and (30 Kg P2O5/fed X Gemmeiza 9) as well as the second order interaction between 112.5 kg N/fed X 30 Kg P2O5/fed X Gemmeiza 9 were significantly recorded the greatest grain yield/fed as compared with the others interactions in the both seasons. It could be summarized that sown wheat Gemmeiza 9 cultivar and fertilization by 30 Kg P2O2 + 112.5 kg N/fed maximized grain yield per unit area. [ABSTRACT FROM AUTHOR]
