SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

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

European 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 ...

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

Pest 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 ...

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

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

Host plant‐specific volatiles of Beauveria bassiana‐colonized plants initiate trophic plant–aphid–predator cascades

Pest Management Science, EarlyView.
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

Bifurcation and Chaos in a Parasitoid-Host-Parasitoid Model

International 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

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

Pest 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.

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

Evolutionary 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.

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

Pest 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
