To clarify this question parallel experiments under field and laboratory conditions have been performed. On April 1(st) 1999 540 eggs (Experiment A) and on May 2(nd) 1999 2 x 600 eggs (Experiment B, C) were exposed in a young mixed stand of pine and spruce near Waake (Southern Lower Saxony). 20 eggs in small Petri dishes each were caged on 3 m to 4 m high trees in 87 replications. All experiments lasted until June 7(th) 1999. In Experiment A (closed buds and mature needles at the time of transferring the eggs into the field) 16% of the L-1-larva survived (Fig. 1); in the Experiment B (commencing four weeks after Exp. A, with sprouting shoots and mature needles present) 48.5% of the larva survived (Fig. 2). In Experiment C (mature needles only) 0% of the larva survived (Fig. 3). At the end of the experiment the attacked shoots were examined regarding their condition. Almost exclusively galleries had been bored into the buds to get access to the young needles which were destroyed; however the stems of the shoots were seldom attacked. Parallel to the field experiments two experiments (D with may shoots, E without may shoots) were carried out under laboratory conditions with L-1-larvae but otherwise the same experimental design. As with the field experiment no larva survived when only mature needles were offered (Fig. 5). May shoots were attacked more heavily than in the field and eaten almost completely The development of the individuals of the respective populations was much more extended under field- than under laboratory conditions. It is clearly concluded from the experiments that the L-1-larva of Panolis flammea depends on young needles as its first Source of food, sprouting shoots are optimal, closed buds are attacked with minor survival success. The defence reaction of the tree by resin flow does not suppress the attack of the larva but reduces the survival rate."],["dc.identifier.isi","000167249100001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29432"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Sauerlanders Verlag"],["dc.relation.issn","0002-5852"],["dc.title","Survival potential of the L(1)caterpillar of the pine beauty moth (Panolis flammea Linnaeus, 1758: Lepidoptera, Noctuidae) on may-shoots and mature needles of Scotch pine (Pinus sylvestris)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
