Abstract This study is to identify some mutations in exons 23, 24, 26 A+B, and 26 A of the factor VIII gene that causes hemophilia A among Libyan patients. Forty-three patients (40 males, 3 females), 10 carrier, and 10 control (8 males, 2 females) were enrolled in this study. The total number were 63 samples for each exon. Blood samples were collected from Libyan patients (Department of Paediatric Hematology, Tripoli Medical Center), and kept in freezer at -20 Cº. The blood samples were transported to DNA laboratory in the Genetic Engineering Department and Human Tissues Department Biotechnology Research Center, Twesha- Libya. Genomic DNA was extracted from whole blood and DNA was visualized by Agarose Gel Electrophoresis, and DNA concentration was measured by Spectrophotometer. DNA was amplified by polymerase chain reaction (PCR) technique. Mutations were identified by restriction enzymes Taq I and Xba I. Taq I was used to detect nonsense mutations in Exon 23, 2147 [ Arg Stop codon (Term)], Exon 24, 2209 [ Arg Stop codon (Term)], and Exon 26 A+B, 2307 [ Arg Stop codon (Term)]. Our result showed no mutations were detected by using restriction enzyme Taq I in Exons 23, codon 2147, Exon 24, codon 2209, and Exon 26A+B, codon 2307. But by using restriction enzyme Xba I, we found six insertion mutations in Exon 26A, 3919 (ins GA) 11.3 % of 53 patients, and two partial deletion mutations in Exon 23 (3.8 % of 53 patients) refer to area failed to be amplified by PCR.

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.
