Abstract The aim of this study was to investigate the effect of gamma irradiation on survivability (adult emergence, sex ratio, adult longevity), fecundity (eggs hatchability, number of eggs produced), and morphological differences in the size of the ovary and testes of unirradiated and irradiated adults of Oriental fruit fly [Bactrocera dorsalis (Hendel)]. A dose of 100 Gy was determined as the minimum needed for inhibitory effects against B. dorsalis that would not deter adult emergence, sex ratio (male:female), and adult longevity, with 82.6 ±7.02, 1:1.09, and 107 ± 24.5, respectively. Doses from 50 to 400 Gy range did not completely prevent the adult emergence; however, the emergence decreased by increasing the radiation dose. Adult survivability significantly decreased among all the treatment groups of B. dorsalis, except for the 50 Gy and unirradiated flies. At a dose of 50 Gy, fertile females showed a significant reduction in fecundity by not producing eggs after mating with the sterile males. Meanwhile, the number of eggs laid decreased with increasing dose and no fertile egg was hatched starting at 100 Gy of irradiation. Testes and ovaries of 20-d old flies irradiated as pupae were smaller than those of control flies. In this study, 100 Gy was concluded as the minimum effective dose for the disinfestation and sterilization of B. dorsalis puparia. Results represent new findings used as a basis for sterile insect technique and quarantine programs for managing B. dorsalis, particularly in Malaysia.

Epidemiologische Studien

ZusammenfassungZahlreiche epidemiologische Studien zeigen, dass sich das Geschlechterverhältnis der Prävalenz depressiver Erkrankungen ab der 6. Lebensdekade – also nach der weiblichen Menopause – wieder annähert. Wir haben untersucht, ob sich dieser epidemiologische Effekt auch in der stationären Versorgung abbildet. Unter Verwendung der AGATE-Stichtagsdaten der Jahre 2000 bis 2004, wurde der Zusammenhang zwischen Geschlecht und Alter bei stationär behandelten depressiven Patienten analysiert. Der Zusammenhang zwischen Geschlechterverhältnis und dem Alter wurde mithilfe des Korrelationskoeffizienten nach Spearman sowie mit χ2-Test untersucht. In der 5. und 6. Lebensdekade lag die Sex-Ratio F/M bei 1,7:1, sie stieg in der 7. Dekade auf 2,2:1 und in der 8. Dekade auf 2,6:1 an. Anders als aufgrund epidemiologischer Studien zu erwarten wäre, nähert sich in der stationär psychiatrischen Versorgung das Verhältnis depressiver Patienten im Alter nicht an. Depressive ältere Männer sind also im stationären Versorgungssystem unterrepräsentiert.
