Biochar Suppresses Growth, Pupation and Eclosion Success of a Specialist (Manduca sexta) and a Generalist (Spodoptera frugiperda) Insect Herbivore

open access: yesJournal of Sustainable Agriculture and Environment, Volume 4, Issue 2, June 2025.
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

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1294-1306, June 2025.
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.

Endogenous rhythmic growth and ectomycorrhizal fungi modulate priming of antiherbivore defences in subsequently formed new leaves of oak trees

open access: yesJournal of Ecology, Volume 113, Issue 6, Page 1382-1396, June 2025.
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,

Butterflies, bumblebees and hoverflies are equally effective pollinators of Knautia arvensis (Caprifoliaceae), a generalist plant species with compound inflorescences

open access: yesJournal of Applied Entomology, Volume 149, Issue 5, Page 685-696, June 2025.
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]

open access: yes, 2004
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]

open access: yes, 2004
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]

open access: yes, 2009
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.
