A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Inhibition of Spodoptera frugiperda phenoloxidase activity by the products of the Xenorhabdus rhabduscin gene cluster.

PLoS ONE, 2019
We evaluated the impact of bacterial rhabduscin synthesis on bacterial virulence and phenoloxidase inhibition in a Spodoptera model. We first showed that the rhabduscin cluster of the entomopathogenic bacterium Xenorhabdus nematophila was not necessary ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Field application of entomopathogenic agents against the fall armyworm (Spodoptera frugiperda) (J. E. Smith) (Lepidoptera: Noctuidae) in maize

Egyptian Journal of Biological Pest Control
Background Fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), larvae have the potential to significantly reduce maize yields.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Characterization of Xenorhabdus (γ-Proteobacteria) strains associated bacteria with the Steinernema (Nematoda: Steinernematidae) isolates from Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2011
The gram-negative bacterium Xenorhabdus is mutualistically associated with entomopathogenic nematode, Steinernema. Three bacterial strains were isolated from the entomopathogenic nematodes, Steinernema glaseri (Steiner) and S.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Engineered Yarrowia lipolytica inducing gene silencing confers control ability against gray mold in plants

Journal of Integrative Plant Biology, EarlyView.
Engineered the plant‐colonizing yeast Yarrowia lipolytica to produce and deliver double‐stranded RNAs targeting key genes of the gray mold fungus Botrytis cinerea produced a ‘living factory’ that continuously synthesizes and releases gene‐silencing molecules on plant surfaces, effectively suppressing the pathogen.

Infection of the malaria mosquito, Anopheles gambiae, with two species of entomopathogenic fungi: effects of concentration, co-formulation, exposure time and persistence [PDF]

, 2009
Background Entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana isolates have been shown to infect and reduce the survival of mosquito vectors.
