Abstract Bactrocera flies are economic pests of agricultural crops all over the world. Among Bactrocera flies, oriental fruit fly is an economically important pest of fruit crops in the world. Basic studies of Bactrocera flies are very important and helpful to the development of integrated management strategies. However, basic studies regarding behavior and age-stage, two-sex life table traits for this pest, which are vital for designing effective control methods, are currently lacking. Considering the importance of B. dorsalis, this study aimed to evaluate the fruit preference and age-stage, two-sex life table traits of B. dorsalis on guava (Psidium guajava), papaya (Carica papaya), and banana (Musa acuminata) fruits in the laboratory. In choice and no-choice tests, the number of visits and oviposition punctures made by female B. dorsalis flies were significantly higher on guava than those on papaya and banana. The life cycle from eggs to male (146.95 ± 3.43 d) and female (164.94 ± 3.85 d) adults was significantly longer on papaya than those on banana and guava. Bactrocera dorsalis females produced significantly more eggs when fed on guava (623.30 eggs female−1) than on papaya (527.80 eggs female−1) or banana (399.60 eggs female−1). Guava was the more suitable fruit for B. dorsalis, and could be used as a bait fruit to manage the B. dorsalis during the fruiting season of papaya and banana.

Oriental fruit fly, Bactrocera dorsalis, is a serious invasive pest in tropical and subtropical countries. The stage-specific two-sex pooled life table of B. dorsalis on four different fruits (guava, water apple, rose apple and mango) were studied during 2018-2020. The life table showed that the survivorship of B. dorsalis falls in Type III with about 41.394-33.827per cent of the eggs successfully reached adult stage. The highest mortality recorded was in the egg and adult emergence stages with kx of 0.045-0.113 and 0.032-0.192, respectively. The average potential fecundity (Pf) was 223-362 eggs female-1. The intrinsic rate of natural increase (rm) was 0.021-0.035 female-1 day-1 with mean generation time (Tc) of 194.058-148.710 days. The net reproductive rate (Ro) was 61.504-176.006 female offspring per female and the population doubling time (DT) was within 32.719-19.946 days. The population dynamics of B. dorsalis were significantly influenced by the host fruits due to their respective phytoconstituents in terms of host suitability or susceptibility (guava> water apple> rose apple> mango). Host preference of B. dorsalis was in the order of guava> water apple>rose apple.

SummaryPost-infusion hepatitis is known to occur very frequently in haemophiliacs after treatment with unheated commercial clotting factor concentrates, obtained from large plasma donation pool. On the contrary, single-donor cryoprecipitate is likely to carry a lower risk of transmitting hepatitis.To evaluate this hypothesis, we retrospectively reviewed the medical records of 25 first infused haemophiliacs (from 1981 to 1984) treated with unheated commercial clotting factor concentrates (n = 19) or cryoprecipitate (n = 6).The hepatitis-free interval after the beginning of therapy was expressed as exposure days. The end point of each patient, i.e. the hepatitis occurrence, was defined as an increase of aminotransferases (ALT and AST) and/or the seroconversion of HBV-markers, which were checked every three months.The life-table method and log-rank test showed that cryo-precipitates had a significantly longer hepatitis-free interval (p = 0.0131, log-rank test) and a lower risk of transmitting hepatitis (p = 0.01-0.05, life-table method) than the commercial concentrates. However, the safety of cryoprecipitate therapy was shown to cover only a few exposure days, and so the real advantage of this product depends on the bleeding frequency of the patient concerned.We believe that these methods and our findings may be useful to assess and compare the safety of the new “heat-treated” clotting factor concentrates.

The objective of the research were to investigate level parasitization, immature development period, longevity of adult parasitoids, along with number of progeny and parasitoid sex of Psyttalia sp. attacking larvae of Bactrocera dorsalis. This experiment was conducted in Laboratory of Entomology, Department Plant Pest and Diseases Faculty of Agriculture, Sriwijaya University from March to September 2007. The result showed that the average level of parasitization of Psyttalia sp. reached 24.24%. The highest one was 30% and the lowest was 16.7%. The immature development period of Psyttalia sp. ranged from 24-31 days with average 27.5 days. Longevity of imago parasitoids which stored at 5 0C was 14.1 days. In the research, the progeny of parasitoids which produced was females with percentage of females reached 59.99% and percentage of males reached 39.99%.Keywords: fruit flies, Bactrocera dorsalis, parasitoid, Psyttalia sp.
