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>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">PROTA, R</style></author><author><style face="normal" font="default" size="100%">DELRIO, G</style></author><author><style face="normal" font="default" size="100%">FLORIS, I</style></author><author><style face="normal" font="default" size="100%">LENTINI, A</style></author><author><style face="normal" font="default" size="100%">LUCIANO, P</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Teller, A and Mathy, P and Jeffers, J N R</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">ENTOMOLOGICAL ASPECTS OF THE PROTECTION OF QUERCUS-SUBER L FORESTS IN SARDINIA</style></title><secondary-title><style face="normal" font="default" size="100%">RESPONSES OF FOREST ECOSYSTEMS TO ENVIRONMENTAL CHANGES</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">defoliation</style></keyword><keyword><style  face="normal" font="default" size="100%">lepidoptera</style></keyword><keyword><style  face="normal" font="default" size="100%">Sardinia</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER APPL SCI PUBL LTD</style></publisher><pub-location><style face="normal" font="default" size="100%">BARKING ESSEX</style></pub-location><pages><style face="normal" font="default" size="100%">972-973</style></pages><isbn><style face="normal" font="default" size="100%">1-85166-878-0</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the Sardinian cork oak forests, more than 300 species of Lepidoptera have been found, 10% of which develop on Quercus suber L. trees. The population density of these insects varies greatly, and, in some cases, is so high that causes total defoliation on large scale. Three species in particular cause serious damage: Lymantria dispar L., and Malacosoma neustria L. with periodic infestations and Tortrix viridana L. with temporary ones. There are also other, less harmful species, such as Dryobota labecula Esp., Dryobotodes monochroma Esp., Dryobotodes eremita Fabr., Orthosia cruda Den. &amp; Schiff., Spudaea ruticilla Esp. and Phalera bucephala (L.) that have different fluctuations which can be described as latent or periodic (3).</style></abstract></record></records></xml>
