The comparison of means showed a high significance between eggs mass quantified during the years 2007 and 2008 with respective averages of 135 and 29 per tree. At the second year, eggs mass measurements and quantification of eggs laid have found significant reduction surface of 40% and the 65% average number of eggs. Frequency analysis of surfaces and the number of eggs have revealed five classes for the two generations considered. The data confirm the typical pattern of a gradation of Lymantria dispar.</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%">Villemant, C</style></author><author><style face="normal" font="default" size="100%">Ramzi, H</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Predators of Lymantria dispar (Lep.

(Lepidoptera: Lymantriidae) are one of the main mortality factors influencing pest population dynamics. The predators destroy egg masses more by disrupting their cohesiveness than by predation. 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></records></xml>
