    The Drosophila Nora virus is an enteric virus, transmitted via feces2009In: Journal of Invertebrate Pathology, ISSN 0022-2011, E-ISSN 1096-0805, Vol. 101, p. 29-33Article in journal (Refereed)
    Abstract [en]

    The biology of the Drosophila viruses has not been intensely investigated. Here we have investigated the biology of the Nora virus, a persistent Drosophila virus. We find that injected Nora virus is able to replicate in the flies, reaching a high titer that is maintained in the next generation. There is a remarkable variation in the viral loads of individual flies in persistently infected stocks; the titers can differ by three orders of magnitude. The Nora virus is mainly found in the intestine of infected flies, and the histology of these infected intestines show increased vacuolization. The virus is excreted in the feces and is horizontally transmitted. The Nora virus infection has a very mild effect on the longevity of the flies, and no significant effect on the number of eggs laid and the percent of eggs that develop to adults.

    Variation in immune defence in relation to age in the green-veined white butterfly (Pieris napi L.)2012In: Journal of Invertebrate Pathology, ISSN 0022-2011, E-ISSN 1096-0805, Vol. 111, no 3, p. 252-254Article in journal (Refereed)
    Abstract [en]

    We investigate how encapsulation ability varies with adult age in overwintering and in direct-developing animals (development without diapause) of the green-veined white butterfly, Pieris napi. Encapsulation is a resource costly trait coupled to the immune system and encapsulation ability is predicted to decrease with age, since the resource pool of important nutrients generally decreases with age in nectar feeding butterflies. The results support this prediction and both sexes showed an age dependent decrease in their encapsulation ability. There were no significant differences between the sexes but direct-developing males tended to have a steeper decrease than females and we hypothesize that this could be the result of low available resources, since this generation is time and nutrient stressed.
