A laboratory experiment was conducted to examine the efficacy of summer oil (kz
oil 95%) at concentrations 0.5 and 1% and sulfur dusting on oviposition of Tuta absoluta,
where each plant consumed about 15 ml of spraying liquid and about 0.75 gr of
sulphur.
One month -old tomato plants in pots were used; each pot contained two plants considered
one replicate of treatment and repeated three times. Control plants were treated with water
only. Plants were placed randomizely in three cages each contained four pots, a replicate of
all treatments. A choice test was carried out , where four pairs of adult insects (male and
female) were released in each cage .The number of eggs laid by females was recorded in
3, 6 and 10 days after insects released. Results showed that all tested compounds had a
repellent effect on oviposition of Tuta absoluta which continued 6 days after insects
release, where the summer oil at concentration 0.5and 1% caused a decrease in eggs
number 59.45 and%76.95 respectively، and sulfur caused a decrease 56.23% compared
with the control. The effect of tested compounds decreased in ten days.
This research fox on the mechanisms of argumentative inference
to the poetry of Early Islamic era , and we don't mean of inference
the strict logical one , but the pragmatic inference which
fucuses on language in the context of use and in the soci
al and
cultural context . And this study isn't restricted on political dialectic
poetries , so that how many poetries exudes self disappear behind it
deep argumentative dimension .
The role of Interleukin-1 genes in the association between chronic periodontitis
and atherosclerosis has been under debate. The purpose of this study is to compare the existence of
interleukin1 genes polymorphism in the chronic periodontitis subjects with and without atherosclerosis.
This research was conducted at the Laboratory of Tissue Culture, Faculty of Agriculture, Tishreen University. Because of the importance of the food and economic of chickpea, two Winter chickpea cultivars (Ghab 4, Ghab 5) and two Vernal chickpea culti
vars were used (ILC263, ILC1929) and planted in pots until flowering, so the floral buds were picked before opened and washed with distilled water and alcohol three times. Anthers were separated and treated at preliminary temperatures (4 Cْ for 48 hours, and 35 Cْ for 12 hours), then it washed with a solution of hypochlorite of sodium( Naocl 2%) for a period of 15 minute, and washed with distilled sterilized water ,then where planted on the environment Murashige and Skoog ( MS) equipped with 1, 3 and 5 mg/L of auxin 2,4, D, as well as 0.1, 0.2 and 0.3 mg /L of Cytokinin Benzyl Amino Purine( BAP) individually and with interaction between them and incubated under conditions of 27 Cْ and 75% of the humidity and the intensity of 1500 Lux of light for 16 hours. The main objective of research was to study the effect of both preliminary heating treatment , quality and concentration of used hormone on producing callus from used chickpea cultivars anthers. Results showed difference in cultivars response in the treatment of both temperature and single hormone, so Ghab 5 cultivar was the most responsive to the formation of callus, while the results indicated that the highest percentage of the formation of callus was 40% when treated at 4 Cْ of Ghab 4 and Ghab 5 cultivars, while ILC263 cultivar showed less response in all the individual treatments for growth regulators.
As well as results showed that the significant and catalyst role for using of hormones together with heat treatment, where each of Ghab 5, Ghab 4 and ILC1929 cultivars were the superiority, by the arrival of the percentage of 80% and 60%, respectively.
Unemployment constitutes the most dangerous problem which faces the Arab economy, Unemployment is considered a huge waste of unemployed human society capabilities, which is a heavy burden the national economy and need to putting policies for finding
solutions for this problem and limiting the increase of its averages and trying to reduce its rates that unemployment in. Arabcounrties. is a structural problem and concentrates in young people and those who have recently entered the labour market, especially educated groups suggests that the solution of the problem lies in enhancing the investment climate putting policies for finding solutions for this problem and limiting the increase of its averages and trying to reduce its rates.
