From 1987 to 1990, the impact of oophagous enemies significantly contributed to the collapse of a localized gypsy moth outbreak. Variation of egg mass dislocation intensity was greater between trees than among the different strata of a tree. The number of gypsy moth egg masses and egg predator attacks increased when oaks were large and unhealthy. Forest degradation probably explains why egg mass destruction rates were so high (60 to 90% of the eggs) in the infested forest. Oophagous predators find food and shelter under the dehiscent bark of unhealthy cork oaks.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fraval, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">La régulation des populations de Lymantria dispar (L.)

(Lep., Lymantriidae), the Gypsy Moth, is a major pest in several forest areas from Japan to U.S.A. On the atlantic coastal plains of Morocco host-plant is cork oak, Quercus suber (L.). Depending upon the forests, its populations are latent or cyclic. In this later case, population dynamics are governed by quantitative and qualitative variations of the food provided by the tree (Fraval 1984).This paper deals with other factors acting as population regulators. Climate may have mainly indirect effects, modifying nutritional substrate. There are few natural enemies and we never observed any epizootic; gypsy moth population are affected by sudden and heavy mortalities triggered by trophic factors. Entomophagous insects rarely are efficient. Human activities have multiple effects upon cork oaks forests: trees are weakened and become more favourable to the insect pest; controlling measures are seldom. The mode gypsy moth population regulation that is described here seems to be specific. Résumé Lymantria dispar (L.) (Lép.; Lymantriidae) est un ravageur redoutable de diverses forêts, depuis le Japon jusqu'aux U.S.A. Dans les plaines de la bordure atlantique du Maroc, il vit sur Chêne-liège, Quercus suber (L.); selon les forêts, ses populations demeurent très peu denses (mode latent) ou bien passent par des phases de pullulation entrecoupées de périodes de latence (mode cyclique). Dans ce dernier cas, les variations quantitatives et qualitatives de l'alimentation, dues aux particularités de Q. suber, gouvernent la dynamique de ses populations (Fraval 1984). Les rôles d'autres facteurs sont examinés ici. Le climat semble agir surtout de façon indirecte, en modifiant le substrat alimentaire. Les ennemis naturels sont peu diversifiés et aucune épizootie n'a été remarquée; leurs populations sont sous la dépendance des mortalités brutales et massives engen-drées par le jeu des facteurs trophiques. L'impact des entomophages est le plus souvent négligea-ble. Les actions de l'Homme sont multiples dans les suberaies; la plupart affaiblissent les arbres, en les rendant plus favorables au ravageur; les interventions de lutte sont exceptionnelles. La façon dont les populations de L. dispar sont régulées apparaît originale. Zusammenfassung Zur Populationsregulation bei Lymantria dispar (L.) (Lep., Lymantriidae) in Korkeichenwäldern West-Marokkos: Einwirkungen des Klimas, der Entomophagen und des MenschenDer Schwammspinner, der von Japan bis zu den USA verbreitet ist, findet in Marokko in der Korkeiche, Quercus suber, seine Wirtspflanze. In Abhängigkeit von den Baumbeständen sind seine Populationen latent oder sich zyklisch vermehrend. Im letzteren Fall wird seine Populationsdynamik von den quantitativen und qualitativen Veränderungen des Nahrungswerts der Blätter bestimmt.Die vorliegende Arbeit behandelt die anderen Regulationsfaktoren. Das Klima hat vor allem indirekte, die Nahrung beeinflussende Wirkung. Es gibt wenige natürliche Feinde, und es werden niemals Epizootien beobachtet. Die Populationsdynamik des Schwammspinners wird durch plötzliche und starke Schwankungen unter dem Einflußtrophischer Faktoren bestimmt. Entomo-phage Insekten sind selten wirksam. Die Aktivitäten des Menschen resultieren in einer Schwächung und Schädlingsdisponierung der Bäume. Bekämpfungsmaßnahmen werden selten durchgeführt. Der hier beschriebene populationsdynamische Modus scheint artspezifisch zu sein.</style></abstract></record></records></xml>
