Phengaris (Maculinea) alcon butterflies deposit their eggs on tall plants with many large buds in the vicinity of Myrmica ants
The survival of eggs and larvae is dependent on the oviposition site selection of their mothers. In obligate myrmecophilic butterflies, both host plant phenology and host ant presence are expected toExpand
Myrmica aloba (Hymenoptera: Formicidae) hosts isolated populations of a hoverfly, a butterfly and an ichneumon species in NE-Portugal
Larvae and pupae of the obligately myrmecophilous social parasites Microdon myrmicae (Diptera: Syrphidae) and Maculinea alcon (Lepidoptera: Lycaenidae) were found using exclusively Myrmica alobaExpand
Characterization of a Maculinea alcon population in the Alvão Natural Park (Portugal) by a mark-recapture method
The blue alcon, Maculinea alcon located at the Alvao Natural Park was studied by markrecapture methods in order to estimate population size and flight range of the butterflies. Sampling was madeExpand
Effect of different hosts onThaumetopoea pityocampa populations in northeast Portugal
A study was carried out at the Natural Park of Montesinho, NE Portugal, in order to evaluate the effect of different pine species (Pinus pinaster Ait.,P. nigra Arn. andP. sylvestris L.)Expand
The habitat vegetational structure and the success of the blue alcon, Maculinea alcon (Denis & Schiffermüller)
Abstract In the present work, we report the first reference for blue alcon, Maculinea alcon (Denis & Schiffermüller) (Lepidoptera, Lycaenidae), in Portugal. This butterfly species maintains a complexExpand
Effects of defoliation by the pine processionary moth Thaumetopoea pityocampa on biomass growth of young stands of Pinus pinaster in northern Portugal
Abstract: Biomass growth models for 13-year-old maritime pine tree stands (Pinus pinaster Ait.) in the north-eastern Portugal were developed and used to analyse the effects of the defoliation by theExpand
Spatial distribution and sampling of Thaumetopoea pityocampa (Den. & Schiff.) (Lep. Thaumetopoeidea) populations on Pinus pinaster Ait. in Montesinho, N. Portugal
Abstract The pine processionary moth, Thaumetopoea pityocampa (Den. & Schiff.) is one of the most destructive pine pests in the Mediterranean countries. The first objective of this study was toExpand
Influence of host plant phenology and oviposition date on the oviposition pattern and offspring performance of the butterfly Phengaris alcon
The timing of oviposition and selection of the phenological stage of the host plant can have significant consequences for development and success of offspring, and is particularly important forExpand
Maculinea alcon exploits Myrmica aloba in Portugal: unusual host ant species of a myrmecophilous butterfly in a peripheral region
Larvae of the obligate myrmecophilous social parasite Maculinea alcon (Lepidoptera: Lycaenidae) were found exclusively using Myrmica aloba (Hymenoptera: Formicidae) ant hosts in NE-Portugal. This isExpand
Evaluation of native plant species from the olive agro ecosystem to enhance conservation biological control.
The present study aimed to assess the potential of three native plant species from the olive agro ecosystem (corn spurry, Spergula arvensis L., common mallow, Malva neglecta Wallr. and wild fennel,Expand
