Interactions between ants and pine weevils [PDF]

open access: yes, 2014
Ants interact with plants in various ways and ant presence on plants can decrease local abundance or activity of herbivores, which in turn increases plant fitness. Red wood ants (Formica rufa group) are common species in forests of northern Europe.

Larval character evolution in Holometabola (Insecta)

open access: yesCladistics, EarlyView.
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Inflorescence attractivity and dynamics of emergence of Elaeidobius sp. (Coleoptera: Curculionidae), a key pollinator in oil palm agrosystem in Cameroon☆

open access: yesOilseeds and fats, crops and lipids
Elaeidobius spp. (Coleoptera: Curculionidae) are essential for the pollination of oil palms. Elaeidobius kamerunicus is the most studied pollinator weevil of oil palms. Elaeidobius subvittatus and E. plagiatus, which are also common, are less studied. An

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...
