Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation. [PDF]

Mol Ecol
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo. [PDF]

Pest Manag Sci
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Assessing Biodiversity in Agricultural Landscapes Through Drone-Based Environmental DNA Sampling. [PDF]

Ecol Evol
We developed a drone‐based environmental DNA (eDNA) swabbing method to assess hexapod diversity in agricultural fields under three management types (conventional, organic, and IP‐Suisse), detecting 75 taxa across 19 families. eDNA replicates showed consistent within‐field results, though no significant differences in diversity were found between ...

Mycoviruses as Biocontrol Agents: Potential Applications for Managing Pests and Diseases of Oilseed Rape (Brassica napus). [PDF]

Physiol Plant
ABSTRACT Oilseed rape (Brassica napus) production faces a wide range of biotic threats. Pests typically pose a greater threat than diseases to oilseed rape, yet both vary considerably across the major cultivating regions. Management strategies often rely heavily on the use of chemical pesticides which may have harmful effects on the environment, thus ...
