Host phylogeny and ecological associations best explain Wolbachia host shifts in scale insects
Abstract Wolbachia are among the most prevalent and widespread endosymbiotic bacteria on Earth. Wolbachia's success in infecting an enormous number of arthropod species is attributed to two features: the range of phenotypes they induce in their hosts, and their ability to switch between host species.

Commodity risk assessment of Malus domestica plants from Turkey
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by dormant grafted plants, rootstocks, budwood and ...

Pollinators beneath the rainforest canopy occupy a unique microclimate that is markedly different from the canopy environment that receives more light energy. We studied the floral attractants and floral visitors of a dioecious, subcanopy rainforest tree, Fontainea picrosperma (Euphorbiaceae), in northern Australia.

Arthropod facilitation mediated by abandoned dead domatia
Abstract In ant–plant mutualistic interactions, plants provide shelter (domatia) and/or food to ants and in exchange, and ants provide protection against herbivores. After plant tissue senescence, ants are expected to abandon dead domatia, leaving these empty spaces available for other arthropods.

Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Carboniferous fossils enlighten the systematics and evolution of Hemiptera
Abstract Fossils are witnesses to the evolutionary processes undergone by living lineages. The earliest occurrence of clades provides rich insights into the timing of diversification of lineages and better delimits the groups that compose them. Hemiptera are a remarkable order within the insects due to their high morphological and ecological diversity.

Pest categorisation of non‐EU Margarodidae
Abstract The Panel on Plant Health performed a pest categorisation of species in the family Margarodidae (Hemiptera: Coccomorpha; Coccoidea). Of 107 species of Margarodidae, 97 are not known to occur in the EU. Margarodids are cosmopolitan soil‐dwelling species. The nymphs suck on the roots of host plants, while the adults have no mouthparts and do not

Farmland ecotones support high parasitoid diversity, despite lower arthropod richness compared to semi‐natural habitats. Farmland ecotones support high pentatomoid bug abundance, while pentatomoid parasitoids were equally abundant and diverse in both ecotones.

Evolutionary conservation of candidate osmoregulation genes in plant phloem sap‐feeding insects
Abstract The high osmotic pressure generated by sugars in plant phloem sap is reduced in phloem‐feeding aphids by sugar transformations and facilitated water flux in the gut. The genes mediating these osmoregulatory functions have been identified and validated empirically in the pea aphid Acyrthosiphon pisum: sucrase 1 (SUC1), a sucrase in glycoside ...

ABSTRACT Humans play key roles in shaping the structure and processes of ecosystems globally, especially in cities. This recognition has prompted a recent focus on understanding urban systems via interactions between human social systems and ecological and evolutionary processes.
