ABSTRACT Biochar is a charcoal‐like substance made by the pyrolysis of organic material from agricultural and forestry waste. While biochar is well documented for altering soil physicochemical conditions, few studies have investigated its possible effects on the management of arthropod pests.

Long‐term population dynamics of an insect in a simple food web under a changing environment
This long‐term population study illustrates the complexity of weather effects on insects and how population variability depends on the form of density dependence. Weak regulation leads to long‐term fluctuations without clear traces on short‐term variation. Responses to even drastic changes can be hard to detect without accurate knowledge of mechanisms.

A first herbivore attack primes direct and indirect defences of newly formed oak leaves and, the specific display of defence priming is regulated by rhythmic growth, and modulated by the interaction with the ectomycorrhizal fungus Piloderma croceum. Therefore, the priming memory in oaks can be transmitted to the next growth cycle. GC, growth cycle; SF,

Abstract Plant‐pollinator interactions exist along a continuum from complete specialisation to highly generalised, that may vary in time and space. A long‐held assumption is that large bees are usually the most effective pollinators of generalist plants.

Activity spectrum of spinosad and indoxacarb : rationale for an innovative pyrethroid resistance management strategy in West Africa [PDF]
To face pyrethroid resistance in the cotton ballworm Helicoverpa armigera (Hübner), endosulfan (700 g/ha) has been used in a resistance management strategy for four years in Côte d'Ivoire, West Africa.

Monitoring insecticide resistance in the bollworm Helicoverpa armigera (Hübner) from 1998 to 2002 in Cote d'Ivoire, West Africa [PDF]
Helicoverpa armigera (Hübner) is the major insect pest of the cotton crop in West Africa. Populations recently developed resistance to pyrethroids via the overproduction of oxidases.

Habronyx Foerster (Hymenoptera: Ichneumonidae: Anomaloninae) in Andean and Neantarctic South Americawith description of new species from Bolivia and Chile [PDF]
Habronyx Foerster occurs in all regions except the Afrotropical and parasitizes lepidopterous larvae (Geometridae, Noctuidae, Saturniidae, Sphingidae, Psychidae). Habronyx albifrons (Spinola) inhabits neantartic Chile and southern Argentina.
