Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Detection and avoidance of an entomopathogenic fungus by a generalist insect predator [PDF]

, 2006
1. Increasing evidence suggests that insects can assess their environment based on cues related to mortality risks to themselves or their offspring. Limited knowledge is available on such abilities in relation to entomopathogenic fungi, which can cause ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Chlorfenapyr: a pyrrole insecticide for the control of pyrethroid or DDT resistant Anopheles gambiae (Diptera: Culicidae) mosquitoes. [PDF]

, 2007
Owing to the development and spread of pyrethroid resistance in Anopheles gambiae in Africa there is an urgent need to develop alternative insecticides to supplement the pyrethroids.

Chromosome level assembly and secondary metabolite potential of the parasitic fungus Cordyceps militaris

BMC Genomics, 2017
Background Cordyceps militaris is an insect pathogenic fungus that is prized for its use in traditional medicine. This and other entomopathogenic fungi are understudied sources for the discovery of new bioactive molecules. In this study, PacBio SMRT long

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

Entomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.

Evaluation of synthetic repellents on mosquito nets in experimental huts against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes. [PDF]

, 2006
Owing to the development of pyrethroid resistance in Anopheles gambiae, there is a need to develop chemical alternatives for use on mosquito nets. Synthetic insect repellents are widely used for personal protection as skin or clothing applications.

The combination of the entomopathogenic fungus Metarhizium anisopliae with the insecticide Imidacloprid increases virulence against the dengue vector Aedes aegypti (Diptera: Culicidae)

Parasites & Vectors, 2011
Background Dengue fever transmitted by the mosquito Aedes aegypti, is one of the most rapidly spreading insect borne diseases, stimulating the search for alternatives to current control measures. The dengue vector A.

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.
