(Lepidoptera: Lymantriidae) were characterized using geostatistical and climate models. Data on gypsy moth egg mass abundance recorded at 282 permanent monitoring sites from 1980 to 2004 were incorporated in a geographic information system with the vegetational, geomorphological and pedological features of the sites. 2 Statistical analyses revealed that the relative outbreak frequency was related to the predominant host tree, slope and elevation of the monitoring sites, whereas there was no correlation between outbreak frequency and exposure and soil type. 3 By using bioclimatic modelling, probability maps of gypsy moth outbreaks were generated. The model identiﬁed a probability surface with climatic conditions favourable to gypsy moth outbreaks and thus potentially subject to defoliation. The maps included 92 sites where outbreaks never occurred, suggesting that the Sardinian climate may not be a determinant factor for gypsy moth outbreaks. 4 The geostatistical method cokriging with outbreak frequency as a covariate was found to be the most suitable technique to estimate gypsy moth egg mass abundance. Semivariograms showed spatial correlation of egg mass abundance within the range 18.5–53 km. The results obtained were used to create regional gypsy moth distribution maps by cokriging, which demonstrated the outbreak foci and different infestation levels at each monitoring area.

Numbers were very similar in the two study years, but adult emergence was delayed 15 days in the second year as a consequence of variation in weather conditions. The nectar sources used by adults were different in the two years and were correlated with the most abundant plants available during the flight period. Adult abundance was correlated with the pre- sence of the larval foodplant (Lonicera periclymenum) in open woodland and was higher where this habitat was mixed with open areas, where nectar sources abound. Estimates of male population numbers were higher than those of females, suggesting that males used wider ranges than females, or a higher residence rate for males. Nevertheless mobility did not differ significantly between the sexes. The conservation of the species in central Spain depends on maintaining patches of oak wood- lands, important for the presence of larval foodplants. Large numbers of the butterfly in the Natural Park study area are favoured by traditional management including charcoal production and extensive grazing by cattle and goats.</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>
