“…This adult parasite overwinters beneath the bark of 01 B apple cuuduta Ratz. (COUTIN and COLOMBIN 1960;Russ and RUPF 1975;LABANOWSKI 1981) have been reported in Europe, whilst Liotyphon crassiseta was found in this investigation. ROSENBERC (1934) has described the life cycle of the related L. punctuluta, which attacks the larvae when they are already in cocoons.…”

“…Mortality rates of the mainly studied codling moth population in this investigation were hi her than results obtained from samples of larvae from card-(ZECH 1959;COUTIN and COLOMBIN 1960;LEHMANN 1968;Russ and RUDF 1975;LABANOWSKI 1981). The more intense total parasitism observed in this investigation (table 5) may be the outcome of a higher redation by birds on that gave rise to the higher density to certain parasites.…”

“…The occurrence of the endoparasite Sinophorus rufifemur which emerged from the collection in Skine, has also been reported from France (COUTIN and COLOMBIN 1960). The parasite emerges from the larvae by spinning a colourless cocoon outside that of the host's larval skin.…”

Overwintered larvae, and pupae of the codling moth were scraped from apple tree trunks in spring 1981–1984 and investigated for parasites and pathogenes. The total mortality ranged from 49.6 to 77.8 %. Elodia morio Fall. (Tachinidae) was the most common species among the parasites that emerged during the years (50.6 %). Possible reasons why a higher percentage of E. morio were found in this investigation as compared with other european countries are discussed. Pristomerus vulnerator Panz. (Ichneumonidae) and Ascogaster quadridentatus Wesm. (Braconidae) were the second most common (22.9 and 14.7 %, respectively). Of the cadavers collected in 1981–1982, the fungal pathogenes Beauveria bassiana (Bals.) Vuill. and Paecilomyces farinosus (Dicks, ex Fr.) Brown et Smith, accounted for an infection rate of 34.4 and 29.5 %, respectively. Totally 26.2 % of the experimentally exposed overwintering codling moth larvae were taken by birds. Although based on a small number of samples, birds showed a clear tendency to density‐dependent predation. Zusammenfassung Die natürlichen Feinde des Apfelwicklers (Laspeyresia pomonella L.) (Lep., Tortricidae) und ihr Einfluß auf überwinternde Populationen in Südschweden Überwinterte Larven sowie Puppen des Apfelwicklers wurden 1981–1984 im Frühling von Apfelbaumstämmen geschabt und auf Parasiten und Pathogene untersucht. Die Gesamtmortalität lag zwischen 49,6 und 77,8 %. Elodia morio Fall. (Tachinidae) war die häufigste Art unter den im Verlauf der Jahre schlüpfenden Parasiten (50,6 %). Die möglichen Gründe, weshalb in dieser Untersuchung ein höherer Prozentsatz von E. morio als in anderen europäischen Ländern gefunden wurde, werden diskutiert. Pristomerus vulnerator Panz. (Ichneumonidae) und Ascogaster quadridentatus Wesm. (Braconidae) waren die nächsthäufigsten Arten (22,9 bzw. 14,7 %). In 1981 und 1982 eingesammelten, abgestorbenen Exemplaren wurden die Pilze Beauveria bassiana (Bals.) Vuill. und Paecilomyces farinosus (Dicks. ex Fr.) Brown et Smith, mit 34,4 bzw. 29,5 % gefunden. Von experimentell ausgebrachten, überwinternden Apfelwicklerlarven wurden insgesamt 26,2 % von Vögeln gefressen. Trotz der geringen Probenzahl ließen Vögel eine deutliche Tendenz zur dichteabhängigen Prädation erkennen.
