Abstract Biological studies of Nezara viridula (L.) (Heteroptera:Pentatomidae) and its parasitoid Trissolcus basalis (Wollaston)(Scelionidae: Hymenoptera) collected from Libya were conducted in a rearing room at 25 ± 5°C, 65 ± 10 % R.H. and 16:8 LD photoperiod.During the course of rearing of N. viridula the eggs incubation periodvaried between 4-7 days. The newly emerged nymphs and the 5th stage had the highest mortality in comparison with 1st, 2nd, 3rd and 4thstages .studies on T. basalis included: SEM, development time, parasitoid mating behavior and oviposition behavior, functionalresponse and fecundity. The development time was 4 to 10 days underthe laboratory condition. Adult males lived longer than females.Mating time took from 12.2 to 19.5 seconds. In case of ovipositionbehavior serial of behaviors were observed and recorded. The egg selection period was 0: 00: 08 - 0: 00: 25 min, oviposition period was 0: 01: 04 - 0: 01: 41 min. Egg marking period was 0: 00: 11 - 0: 00: 25 min. The longest period was the oviposition period followed by egg marking period followed by egg selection period.In functional response study was found a highly positive correlation ( r = 0.974 ) number of egg masses exposed and the number of parasitoid emerged. Fecundity experiments showed that the daily ii production of progeny by female of T. basalis during 6-10 dayslifetime showed that female progeny production was higher than male progeny production. The maximum period offspring production was 6-10 days. There was a highly negative correlation ( r = - 0.900 ) between the number of eggs parasitized and parasitoid age . Also there is a highly signifcant difference between the fecundity of T. basalis newly emerged of 24 h and after 7 days after emergence from N. viridula eggs. The number of mature eggs in the ovary were less in 24h aged female and the fecundity increased over the next 7 days.

حدوث عدوى الإصابة بفيروس الالتهاب الكبد البائي بعد نقل الدم انخفضت مع إدخال اختبار HBsAg للكشف عن وجود الفيروس في دم المتبرعين، وهذا الاختبار هو الوحيد والروتيني في جميع مراكز نقل الدم في أغلب بلدان العالم، ولكن منع الخطر المتبقي لانتقال عدوى هذا الفيروس عن طريق التبرع بالدم يعتمد في الغالب على فحص دم المتبرعين لوجود Anti-HBc. لاكتشاف المتبرعين في مرحلة الفترة النافذة عند الإصابة بهذا المرض، وانه في العديد من الحالات يكون Anti-HBc هو المؤشر الوحيد للإصابة في الحالات التي ينخفض فيها مستوى HBsAg الى حد لايمكن كشفه وخصوصا في الحالات المزمنة. وهدف هذه الدراسة معرفة مدى انتشار Anti-HBcوAnti-HBsوHBV-DNA لفيروس الالتهاب الكبدي البائي في المتبرعين وإمكانية إدخال هذه الاختبارات ضمن الفحوصات الروتينية الخاصة بفحص دم المتبرعين للوصول لدم الأمن. حيث جمعت 437 عينه متبرع بالدم سالبة لاختبار HBsAg من بعض المستشفيات بمنطقة طرابلس, تم إجراء اختبار Anti-HBc باستخدام تقنيه قياس الامتصاص المناعي المرتبط بالإنزيم Enzyme linked immune sorbent assay(ELISA) وكل العينات الموجبة لاختبار منAnti-HBc والسالبة لاختبار HBsAg تم إجراء اختبار Anti-HBs عليها و ذلك باستخدام تقنيه VIDAS assay ,كل العينات الموجبة لاختبار Anti-HBc والسالبة لاختبار HBsAg والسالبة لاختبار Anti-HBs تم اختبارها للكشف عن DNA الفيروس و ذلك باستخدام  اختبار Cobas Amplicor HBV Monitor test .وبالتالي كانت نسبة وجود Anti- HBc الموجبة في سالبي HBsAg في هذه الدراسة 37(8.4%) وكانت نسبة وجود Anti- HBs السالبة في موجبي Anti- HBcو سالبي HBsAg 8(1.83%) وكان هناك عينة واحدة من 8 عينات سالبة Anti- HBs وموجبي Anti- HBcو سالبي HBsAg تحتوي على DNA الفيروس.ومن هذه النتائج نرى ادخال الاختباراتAnti- HBc و Anti- HBsوPCR ضمن الاختبارات الروتينية لفحص دم المتبرعين داخل مصارف الدم بالمستشفيات. Abstract Incidence of HBV after blood transfusion has decreased with the introduction of HBsAg test to detect the presence of the viurs in blood donors. This test is the only one used as a routine in all blood transfusion centers in most countries of the world. The prevention of residual risk for transmission Hepatitis B Virus (HBV) infection is mostly relied on serological screening of blood donors for antibody to hepatitis B core antigen (anti-HBc), to detect donors in window period in HBV infection, and in many cases anti-HBc is the only serological marker when HBsAg fall to the level that can not be detected especially in chronic cases. Assess the frequency of Anti-HBc (+) , Anti-HBs (-) and HBV-DNA(+) and evaluate whether Anti-HBc, Anti-HBs and HBV-DNA could be adopted as screening assayes for blood donation. Atotal of437 HBsAg negative blood donor samples collected from different hospitals in Tripoli area .All samples were tested for anti-HBc by (ELISA). Anti-HBc-reactive samples were tested for anti-HBs by (VIDAS assay).All samples with anti-HBs negative were further tested by PCR for the presence of HBV-DNA.The prevalence of anti-HBc in these samples was 37 out of 437 samples (8.4 %). prevalence of anti-HBs(-) in this group was 8 out of 37samples (1.83 %).and HBV-DNA was detected in 1 of 8 anti-HBs negative samples. Anti-HBc, Anti-HBs and HBV-DNA should be tested routinely on blood donor.

Abstract This study was carried out to evaluate the exposure of lead (Pb) to some workers in Ash-Shoula lead acid battery Factory, Tajoura, Libya on the basis of concentrations of Pb in blood, hair, and nails. This study was done to explain, if accumulation of Pb could affect the concentration of essential liver enzymes, renal excretion, and some of hematological parameters. Study samples were based on, the number of years of work in battery manufactory, six work periods were constituted (< 5, 6-10, 11-15, 16-20, 21-25, >25 years). Workers were selected from seven different departments of the battery manufactory. Pb concentration in the collected samples were measured by using atomic absorption Spectroscopy. The statistical analysis were performed using SPSS software, version 20. The parametric tests (one-way ANOVA, t-test, and 2-tailed person Correlations) where P-value ≤ 0.05 was considered significant.Blood lead level was found high ranging from 9.9-60.3 μg/dl with a mean of 25.3 μg/dl and was found to be less in control group, ranging from 2.5-24.6 μg/dl with a mean of 11.8 μg/dl. The values of hair lead level were found to be ranging from 8.2-36.8 μg/g, with a mean of 21.1 μg/g and this was significantly higher than the control group (P
