An Evaluation of the Effects of Delayed Parasitism on Daily and Lifetime Fecundity of Aphidius ervi Haliday

open access: yesInsects
The study of parasitoid reproductive behaviour is crucial to understanding how parasitoids influence host population dynamics, and the strategies used by parasitoids to maximize their reproductive success.

‘ILSM': a package to analyze the interconnection structure of tripartite interaction networks

open access: yesEcography, EarlyView.
In natural or human‐disturbed ecosystems, ecological networks often comprise multiple interaction types, which have been increasingly represented by multipartite ecological networks. One important aspect of their network architecture is how different interaction types or subnetworks are interconnected by connector species, here defined as the ...

Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, EarlyView.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Molecular Techniques for the Detection and Differentiation of Host and Parasitoid Species and the Implications for Fruit Fly Management

open access: yesInsects, 2012
Parasitoid detection and identification is a necessary step in the development and implementation of fruit fly biological control strategies employing parasitoid augmentive release.

Bottom–up and top–down diversification: asymmetric processes over space and time

open access: yesOikos, EarlyView.
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversification, and less on top–down processes through enemy‐associated differentiation.

Abundance and host associations of parasitoids attacking frugivorous drosophilids on Iriomote-jima, a subtropical island of Japan

open access: yesEuropean Journal of Entomology, 2012
To understand the factors governing the diversity, abundance and host associations of parasitoids attacking frugivorous drosophilid flies on Iriomote-jima, a subtropical island of Japan, we monitored parasitism on several occasions over the period 2003 ...

Herbivores induce plant chemical defenses based on the identity of their attacking parasitoid

open access: yesOikos, EarlyView.
Many parasitoids increase plant fitness by decreasing herbivore feeding damage. Solitary parasitoids (where only one individual completes development per host) generally cause their hosts to feed less than unparasitized herbivores, reducing pressure on plants to induce chemical defense production.

First record of 3 species of Parasitoid wasps on Coccoidea from Iran [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2015
During faun survey on parasitoids wasps of Coccoidea in Mazandaran province (north of Iran) collected two species of the family Encyrtidae and one species of Aphelinidae family (2010-2013).

High β‐diversity in fig wasp communities driven by species turnover in widely distributed Neotropical fig trees

open access: yesOikos, EarlyView.
Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27
