The American cocoa pod borer, Carmenta foraseminis, an emerging pest of cocoa: A review El barrenador americano de la mazorca de cacao, Carmenta foraseminis, una plaga emergente del cacao: una revisión

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,

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,

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 ...
