Winston Churchill and South Africa: An Enduring, yet Debatable Connection, 1899–1955

History, EarlyView.
Abstract The article traces Churchill's engagement with South Africa, from his time as a newspaper correspondent during the Anglo‐Boer War to his services in both Liberal and Conservative cabinets as well as, ultimately, his premiership. The discussion highlights three phases in this relationship.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Functional validation of a white pupae minimal gene construct in Ceratitis capitata (Diptera: Tephritidae)

Insect Science, EarlyView.
An intronless version of the white pupae (wp) gene was engineered to restore the wild type brown puparium color in white pupae phenotype mutants of the Mediterranean fruit fly, Ceratitis capitata. Functionality of the minimal gene version (mini‐wp) was verified in vivo, as one copy of mini‐wp successfully restored the wild type phenotype in homozygous ...

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

Insect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (
