The date palm Phoenix dactylifera L. is infected by many insects and non-insect pests in Iraq. One of the major pests of palm trees is Dubas Bugs Ommatissus binotatus lybicus Deberg.   .
 
        This study was carried out in two orchards  in terms of Albahadlah - the holy city of Kerbala (the distance between them is about 3 kilometers ) for the period from 09/01/2013 up to 03/04/2014 to study the effect of temperature and relative humidity levels as well as insecticides (plant extracts) Thiamethoxan WC and Alphacypermethrin EC on numerical density of the number of eggs and movable stages (nymphs and adults) as well as on the percentage of male and female Dubas on the palm of the two categories Zahadi and Khstawe on field  conditions.
 
      The results showed an increase numerical density when the average temperature is between 25-33 C° and relative humidity between 30-50% and the heavy torrential rains during the implementation of this study impact in reducing the population density of the instars of moving the insect did not eggs developed by former female preparation affected. The absence of significant differences between the preparation of movable instars rates and the number of eggs for the two categories Zahdi and Khstawe It was noted, but there were significant differences between female adult insect for two classes Zahdi and Khstawe if the overall rate of female adults is 2.26,2.48  Females / 5 Pinnaes / Palm / week for two classes Zahdi and Khstawe ,respectively and the total rate of male adults is 1.86,2.14 Males / 5 Pinnaes / Palm / week for two classes Zahdi and Khstawe ,respectively . As well as the results showed the existence of significant differences between the effect of pesticides on the overall rate of live stages of the two categories Zahdi and Khstawe and the presence of significant differences dead stages is 4.56 insects / Pinnae of the variety and ascetic 3.26 insects / 10 pinnaes. When the percentage of the effectiveness of insecticides account and found that the percentage of the effectiveness of Alphacypermethin was 19.34% and for Thiamethoxan is 40.78% and the latter was more the effect of the pesticide after 24,48 and 72 hours of control. The decline in the percentage of females and males before control, as was 64.58% for females and 35.42% for males of the variety Zahdi and 59.61% for females and 40.31% for males of the variety Khstawe for increase after the fight, as was 48.26% of females and 26.04% for males of the variety Zahdi and 45.24% for females and 29 0.51% for males of the variety Khstawe.
 
        The results of the effect of insecticides on the population density of the number of eggs did not record any significant differences evident between times beyond control but they differ significantly on the number of eggs living and the dead by the control.

This study was conducted to isolate and identify some bacterial species from the soil surrounding the roots of some weeds Avena fatua L . and Raphanus raphanistrum  L. and to test their antagonistic efficiency in the inhibition of egg hatching and the vitality of juveniles of root knot nematode Meloidogyne spp. in addition to their efficiency in some of growth parameters, severity of infection and root gall index in tomato plants.
 
Results showed the possibility of isolated bacteria to dissolve phosphorus and production of oxidase and chitinase enzymes as well as its ability to tolerate the salinity and liquefy gelatin in addition to its ability for transition movement. Laboratory results were indicated that P. flurescensAzotobacter.chroococcum and Streptomyces spp. were effective in reducing the percentages of hatched nematode eggs, during 72 hours, that were 58.88, 37.46 and 45.50%, respectively.
 
It was also found that the percentage of egg hatching reached 64.07% upon using the bio-mixture that significantly differed from the control treatment that was 0.00%. The results of field trials showed that the treatment of seed witht the genaus of bacteria led to raise the percentage of germination in all treatments compared to the contro ltreatment that gave germination percentage of P. flurescens 85.0%, followed by treatment of the bio-mixture (83.3%), however no significant difference were observed between the P. flurescens treatment and the treatment of bio-mixture.
 
      It was also noticed that the treatment with P. fluorescens gave less disease index (1.9%) followed by the treatment with bio-mixture (2.27) and then the bacteria Streptomyces spp., whereas the highest disease index (3.59%) was found when treating with the bacteria Azotobacter . chroococcum.. Results obtained in this study indicate the possibility of the use of aforementioned bacteria in integrated pest management programs to control the root gall disease in tomato.

 This study was undertaken to investigate the relationship of hemoglobin type with the reproductive performance in Holstein cows for selection purposes. This study was executed at the Dairy Cattle Farm and Physiology Laboratory pertaining to the College of Agriculture, University of Baghdad, as well as in private molecular genetics laboratories during the period from 1/11/2013 to 1/11/2014. Blood samples were collected from 40 Holstein cows, and the hemoglobin types were identified using electrophoresis technique. Records were obtained for cow's reproductive performance and their birth death data until weaning. The effect of hemoglobin type on service per conception, interval between calving and subsequent successful mating and non-return rate to estrus was significant (P≤0.05), being all better in AB type. Greater (P≤0.01) variation was noticed in calving interval trait among the cows, being shorter in AB type. On the other hand, higher and lesser (P≤0.05) calves death rates at calving    (2.95 ± 0.04 and 1.37 ± 0.04% respectively) were detected in those with B and A types respectively. Moreover,  death rates at calving to weaning interval were also influenced by hemoglobin types, being higher (P≤0.05) in B type  (9.82 ± 0.07%), along with non-significant differences detected between A  (4.69 ± 0.07%) and AB (5.08 ± 0.04%) types. In conclusion,  the hemoglobin type can be adopted type of hemoglobin can adopted as selection tool to improve the reproductive performance of Holstein cows, through selecting those with AB type to maximize the economic gain of their breeding projects.
