Intercropping mitigates incidence of the oilseed rape insect pest complex
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

The cabbage stem flea beetle (Psylliodes chrysocephala) is an important pest of oilseed rape (Brassica napus) in Europe. The objective of the present study was to gain a better understanding of host plant related factors affecting its oviposition behaviour with the aim of developing new sustainable control strategies.

Detection of refuge from enemies through phenological mismatching in multitrophic interactions requires season-wide estimation of host abundance [PDF]
The concept of ‘‘enemy-free space’’ (EFS) refers to ways of living that reduce or eliminate the vulnerability of a species to natural enemies. It has been invoked to explain host shifts of phytophagous insects.

A summary of the endemic beetle genera of the West Indies (Insecta: Coleoptera); bioindicators of the evolutionary richness of this Neotropical archipelago [PDF]
The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates.

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Comment on "Magnetic Levitation Stabilized by Streaming Fluid Flows" [PDF]
It is shown that basic origin of radial stability is a centripetal component of the same vibrational force that makes a "flea" levitate.

Leveraging Biodiversity Net Gain to address invertebrate declines in England
Biodiversity Net Gain (BNG) is a new approach to infrastructural development in England, mandating that developers achieve a 10% BNG by enhancing and creating habitats. As currently implemented, BNG risks creating smaller, homogeneous, structurally simple and poorly connected habitats.

A new trapping concept has been proposed based on a volatile compound, allyl isothyocianate, known to be attractant to some of these insects for a long time. (l) The first question was whether this compound is effectively attractive to all flea beetle
