Host specificity and host stage preference of Psyllaephagus species (Hymenoptera: Encyrtidae) towards invasive eucalypt psyllids (Hemiptera: Aphalaridae)

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

Pheromone stereochemical specificity in the biology of the bean beetle Acanthoscelides obtectus

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract The dried bean beetle, Acanthoscelides obtectus, is a serious pest of legume crops, particularly Phaseolus vulgaris beans, and its management is challenging due to the beetle's cryptic larval stage. The major male‐produced pheromone of A. obtectus is methyl (E,R)‐2,4,5‐tetradecatrienoate, crucial for female attraction, with the (S)‐enantiomer ...

Stabilizing adaptation in an invasive species: Alfalfa weevil as a case study

open access: yesAgricultural and Forest Entomology, EarlyView.
Comparison of thermal thresholds, fecundity and longevity across three alfalfa weevil strains (California in the United States, Hamadan in Iran, Ebro Valley in Spain) reveal significant differences in demographic parameters. Weather‐driven physiologically based demographic models (PBDMs) developed from life table data explore strain adaptation to ...
