Symbiont-Mediated Protection against Fungal Pathogens in Pea Aphids: a Role for Pathogen Specificity?

open access: yesApplied and Environmental Microbiology, 2013
Here we show that a bacterial endosymbiont, Regiella insecticola, protects pea aphids (Acyrthosiphon pisum) from the aphid-specific fungal entomopathogen Zoophthora occidentalis but not from the generalist insect fungal pathogen Beauveria bassiana.

Complementarity between Orius predators improves control of foliar and flower pests

open access: yesPest Management Science, EarlyView.
Orius predators are commonly used against thrips in many crops. Certain species are suggested to be more effective against flower pests, while others may control effectively foliar pests. Here, we show that Orius species combinations may complement each other and effectively control both flower and foliar pests on gerbera.

Indirect plant defense may provide economically important pest suppression in sorghum

open access: yesPest Management Science, EarlyView.
Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.

Contrasting Roles of Deoxynivalenol and Nivalenol in Host-Mediated Interactions between Fusarium graminearum and Sitobion avenae

open access: yesToxins, 2016
Fusarium graminearum is the predominant causal species of Fusarium head blight in Europe and North America. Different chemotypes of the species exist, each producing a plethora of mycotoxins.

Comparing constitutive and induced costs of symbiont-conferred resistance to parasitoids in aphids

open access: yesEcology and Evolution, 2013
Host defenses against parasites do not come for free. The evolution of increased resistance can be constrained by constitutive costs associated with possessing defense mechanisms, and by induced costs of deploying them.

Characterization of cyantraniliprole resistance in Spodoptera frugiperda: Selection, inheritance pattern, and cross‐resistance to other diamide insecticides

open access: yesPest Management Science, EarlyView.
A cyantraniliprole‐resistant strain of Spodoptera frugiperda with I4790K mutation exhibited a resistance ratio of 3414‐fold and high cross‐resistance to other diamide insecticides. Abstract BACKGROUND Cyantraniliprole, a diamide insecticide, is widely used in Brazil to control sucking and defoliating pests, including the fall armyworm (Spodoptera ...

Artificially perforated holes in stems of small hogweed mimic ecosystem engineering by a moth

open access: yesJournal of Applied Entomology, Volume 146, Issue 10, Page 1302-1310, December 2022., 2022
Abstract Ecosystem engineers are species that manipulate the physical state of ecosystems and thereby affect the behaviour and ecology of other species. Mature larvae of the parsnip webworm, Depressaria radiella Goeze, chew holes in the hollow stems of Heracleum sphondylium L. into which they pupate.

Fortifying crop defenses: unraveling the molecular arsenal against aphids

open access: yesHorticulture Advances
Aphids cause enormous financial losses to various crop plants on a global scale. Moreover, aphids are vectors for many plant viral diseases that can further hasten crop yield losses.

Apple aphid, Aphis spp. (Hemiptera: Aphididae), and predator populations in an apple orchard at the non-bearing stage: The impact of ground cover and cultivar

open access: yesEuropean Journal of Entomology, 2008
A two-year field experiment was conducted to determine whether a conservation biological control strategy could be applied to enhance the biological control of green apple aphids, Aphis spp., in a high-density and scab-resistant apple orchard at the non ...

Modeling, virtual screening, and enzymatic docking of trehalose 6‐phosphate phosphatase and evaluation of the insecticidal effect of phthalimide, N‐(p‐tolylsulfonyl) on Aedes aegypti (Diptera: Culicidae)

open access: yesPest Management Science, EarlyView.
Schematic diagram of the experimental procedures used to perform the bioinformatic steps and insecticidal assays using trehalose 6‐phosphate phosphatase of Aedes aegypti and the molecule phthalimide, N‐(p‐tolylsulfonyl). Abstract BACKGROUND Aedes aegypti Linnaeus is a medically important vector because of its role in transmitting several arboviruses ...
