Keywords. Macaronesia, Euphorbia, Scolytinae, bark beetles, component communities, niche partitioning, communal nesting, mating system

Abstract. Dead wood of arborescent Euphorbia plants in the Macaronesian islands and Morocco has a diverse fauna of wood-boring beetles. Thirty-eight species were found in four species groups of Euphorbia, including 29 species of scolytine bark beetles, six species of cossonine weevils, two species of Laemophloeidae and one of Monotomidae. All scolytines...

Tachinid parasitoids affect host plant choice by caterpillars to increase caterpillar survival.
Ecology ; INTRODUCTION Recent models of parasite-host interactions include considerations of parasite virulence and parasite transmission (see reviews by Levin and Eden 1990, May 1991, Ebert and Hamilton 1996). These models often assume a trade-off between virulence and other fitness components for the
