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 ...

Bifurcation and Chaos in a Parasitoid-Host-Parasitoid Model

open access: yesInternational Journal of Modern Nonlinear Theory and Application, 2018
This paper discusses a parasitoid-host-parasitoid ecological model and its dynamical behaviors. On the basis of the center manifold theorem and bi-furcation theory, the existence conditions of the flip bifurcation and Neimark-Sacker bifurcation are derived. In the end of the paper, some typical numerical experiments are performed, which illustrate that

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Counties not countries: Variation in host specificity among populations of an aphid parasitoid

open access: yesEvolutionary Applications, 2019
Parasitic wasps are among the most species‐rich groups on Earth. A major cause of this diversity may be local adaptation to host species. However, little is known about variation in host specificity among populations within parasitoid species.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

open access: yesPest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

open access: yesPest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

Community impacts of anthropogenic disturbance: natural enemies exploit multiple routes in pursuit of invading herbivore hosts [PDF]

open access: yes, 2010
Background: Biological invasions provide a window on the process of community assembly. In particular, tracking natural enemy recruitment to invading hosts can reveal the relative roles of coevolution (including local adaptation) and ecological sorting ...

Modelling the phenology of the grapevine leafhopper Erasmoneura vulnerata

open access: yesPest Management Science, EarlyView.
This study developed and validated a phenological population dynamics model for Erasmoneura vulnerata, integrating field monitoring and literature data to reproduce observed seasonal patterns across multiple sites. Abstract BACKGROUND Erasmoneura vulnerata (Fitch) (Hemiptera: Cicadellidae) is an invasive Nearctic leafhopper that has become a pest of ...

Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

open access: yes, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned
