Prays oleae Bern, （Om. andPalpita unionalis Hfib., （Jm. are two of the m.st im.ortant pests in olive groves in Egypt. A 3-year m.nitoring study using sex pherom.ne traps in sem.-arid and arid olive groves was perform.d. In the sem.-arid grove, flight pattern of the Om.was the sam. as in other m.diterranean countries, but in dates concordating plant phenology. The m.th com.letes three generations annually： the first flight is in m.rch to April, the second is in m.y to June and the third occurs in August to October. In the arid olive grove, an interesting flight pattern was observed. First flight was always very close or overlapped with the second one with no m.le catches during August to October. However, eggs were present m.st of the season, indicating unusually high fem.le presence and oviposition activity of the Om.during the absence of m.les in the traps. Generally, m.th densities were significantly lower in low fruiting years than in higher ones and were also lower in the arid olive grove than in the sem.-arid one. In contrast, Jm.m.les were present all season, exhibiting six to seven and three to four overlapping flight peaks in arid and sem.-arid olive groves, respectively. m.th densities were significantly higher in the arid olive grove than those in the sem.-arid one. This study shows that trapping location and fruit beating year are characteristics that strongly affect the grove-specific inform.tion needed to estim.te correctly adult em.rgence and thus the tim.ng of control m.asures.

Efficiency of Bio-Fertilizing as One of the Natural Alternatives to Im.rove the Growth of Khaya senegalensis and Swietenia m.hagoni Trees and for Sustainability

Rabie Forestry and Tim.er Trees Departm.nt Horticulture Research Institute Agricultural Research Center Ismailia Egypt Forestry and Tim.er Trees Departm.nt Horticulture Research Institute Agricultural Research Center Alexandria Egypt Botanical Gardens Departm.nt Horticulture Research Institute Agricultural Research Center Alexandria Egypt Forestry and Tim.er Trees Departm.nt Horticulture Research Institute Agricultural Research Center Giza Egypt

A field experim.nt was carried out at Ism.ilia Research Station, Ism.ilia Governorate from.2020-2022 to im.rove the growth of Khaya senegalensis and Swietenia m.hagoni by using a com.ination of m.neral fertilizer (NPK) and biological fertilizer (Azotobacter chroococcum. Bacillus m.gatherium. and Bacillus circulant) as recom.ended dose under new sandy soils conditions. Split plot designed with four treatm.nts (Control, (50% m.neral fertilizer (m.) + 50% Biological fertilizer (Bio.)), 100% m. and 100% Bio.) of each species. Vegetative growth, leaf area, tree biom.ss, stored carbon, basal area, tree volum., and in the soil both of m.crobial account and m.neral content were determ.ned. The experim.ntal results showed no significant differences between studied species am.ng the m.st studied param.ters except for Khaya senegalensis which gave the highest significant difference in root biom.ss and below-stored carbon than Swietenia m.hagoni. Evidently, the highest significant growth param.ters were 100% m.neral fertilizer followed by (50% m. + 50% Bio.) as com.ared with control. No significant difference between 100% m. and (50% m. + 50% Bio.) of shoot dry biom.ss (15.19 and 12.02 kg, respectively) and above-stored carbon (0.28 and 0.22 m., respectively). m.crobial account and m.neral content in soil were im.roved after cultivation of tree species com.ared to before planting and control, especially with 50% m.neral fertilizer and 50% bio-fertilizer treatm.nt. In conclusion, a treatm.nt containing 50% m.neral fertilizer and 50% bio-fertilizer has led to the ideal Khaya senegalensis and Swietenia m.hagoni growth in sandy soil for cheaper and sustainable.

Journal of Cancer Therapy 2015年第10期6卷 881-888页

Background and Aim. m.lti drug resistant Non ferm.nting gram.negative bacilli (NFGNB) have em.rged as a m.jor cause of health-care associated infections especially in im.unocom.rom.sed hosts. The aim.of the study was to investigate the prevalence of NFGNB as a cause of health-care associated infections (HAI) in cancer patients and determ.ne their resistance pattern. Patients and m.thods: During the study period, 158 NFGNB isolates were collected. m.croscan Walk Away 9 was used for identification and testing for the m.tallo-β-lactam.ses (m.Ls) was done by Im.penem.EDTA com.ined disk synergy test (CDST-IPm.. Results: NFGNB represented 29.0% of infections caused by gram.negative organism.. Carbapenem.resistance, the m.lti-drug resistant (m.R) phenotype, and m.L production were docum.nted in 70%, 63%, and 59% of NFGNB isolates, respectively. m.R-NFGNB rates were significantly higher am.ng hospitalized patients, m.dical departm.nt and those with longer duration of hospital stay (p = 0.034, 0.026, 0.019;respectively) than non m.R-NFGNB. Conclusion: A high level of carbapenem.and m.lti-drug resistance were detected am.ng the non-ferm.nter pathogens isolated from.hospitalized cases and were m.re frequently encountered in high risk adult cancer patients requiring longer duration of hospitalization. The m.R-NFGNB are constituting im.ortant causes of health-care associated infections in cancer patients.
