This study provides the first laboratory assessment of the physiological host range of Istocheta aldrichi, a candidate biological control agent for Popillia japonica in Europe. In sequential no‐choice tests with 14 European scarab beetles, the parasitoid oviposited on six species but successfully developed only in the two Rutelinae Anomala vitis and ...

Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.

"New Perspectives on the Guaranteed Income" [PDF]
Renewed interest in a guaranteed income is evident from the number of books that have been published on the topic in the 1990s. This paper discusses and compares seven of those books: Arguing for Basic Income: Ethical Foundations for a Radical Reform ...

We investigated oviposition site selection and hatchling feeding performance in two sympatric swallowtail butterflies, Papilio xuthus and Papilio memnon (Lepidoptera: Papilionidae), that utilize Citrus trees as host plants. Our study suggests that each species has unique relationships between maternal oviposition preferences and hatchling feeding ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.
