Optimal control and multitrophic physiologically‐based models: The binomial for successful decision support systems in insect pest management

Pest Management Science, EarlyView.
Decision‐making in integrated pest management (IPM) corresponds to an optimisation problem where the plant–pest dynamics and the control actions are constraints and where the objective function accounts for the costs of the treatments and the total income at the harvest time.

Direct and Indirect Effect via Endophytism of Entomopathogenic Fungi on the Fitness of Myzus persicae and Its Ability to Spread PLRV on Tobacco

Insects, 2021
Aphids are major crop pests that transmit more than half of all insect-vectored plant viruses responsible for high yield losses worldwide. Entomopathogenic fungi (EPF) are biological control agents mainly used by foliar application to control herbivores,

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

Journal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Local variation in belowground multitrophic interactions

Soil Biology and Biochemistry, 2009
A growing number of studies point at the involvement of root herbivores in influencing plant performance, community composition and succession. However, little is known about the factors that control root herbivore abundance and the role of local variation in the effectiveness of these factors. Here, we performed a full factorial experiment with plants,

Impact of predicted precipitation scenarios on multitrophic interactions [PDF]

Functional Ecology, 2017
SummaryPredicted changes in the frequency and intensity of extreme rainfall events in theUKhave the potential to disrupt terrestrial ecosystem function. However, responses of different trophic levels to these changes in rainfall patterns, and the underlying mechanisms, are not well‐characterised.This study aimed to investigate how changes in both the ...

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

Plant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Multitrophic level interactions: an introduction

, 2002
Terrestrial ecosystems are characterized by a huge diversity of species and a corresponding diversity of interactions between these species, but community ecology has historically been dominated by interactions between two trophic levels; in particular, plant–herbivore and predator–prey interactions. Only more recently have ecologists become interested

Is it time to shift towards multifactorial biotic stress in plant research?

Plant Stress
In natural and field environments, plants are simultaneously exposed to a diverse set of stressful conditions, like biotic and abiotic stressors, and must respond accordingly.
