Larval Defense against Attack from Parasitoid Wasps Requires Nociceptive Neurons
Parasitoid wasps are a fierce predator of Drosophila larvae. Female Leptopilina boulardi (LB) wasps use a sharp ovipositor to inject eggs into the bodies of Drosophila melanogaster larvae.

Sharpening our understanding of saber‐tooth biomechanics
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Review of Adaptations of Velvet Ants (Hymenoptera: Mutillidae) [PDF]
Mutillid wasps are active and conspicuous insects, but their interactions with each other and with other animals are seldom observed. Mostly indirect evidence is used to postulate that an array of traits represents adaptations to exploit ground-nesting ...

ABSTRACT Enteropathogenic Escherichia coli (EPEC) causes diarrheal disease. Once ingested, these extracellular pathogens attach to the intestinal epithelial cells of their host, collapse the localized microvilli, and generate actin‐rich structures within the host cells that are located beneath the attached bacteria, called “pedestals.” Palladin is an ...

Relationships between Body Size and Parasitic Fitness and Offspring Performance of Sclerodermus pupariae Yang et Yao (Hymenoptera: Bethylidae). [PDF]
The relationship between body size and fitness in parasitoid wasps has several effects on parasitic ability, reproductive behavior in female wasps, and progeny fitness.

Pre-discovery transits of the exoplanets WASP-18 b and WASP-33 b from Hipparcos [PDF]
We recover transits of WASP-18 b and WASP-33 b from Hipparcos (1989-1993) photometry. Marginal detections of HAT-P-56 b and HAT-P-2 b may be also present in the data. New ephemerides are fitted to WASP-18 b and WASP-33 b. A tentative (~1.3 sigma) orbital decay is measured for WASP-18 b, but the implied tidal quality factor (Q' ~ 5 x 10^5) is small and ...

Adaptive Selection on Bracovirus Genomes Drives the Specialization of Cotesia Parasitoid Wasps
The geographic mosaic of coevolution predicts parasite virulence should be locally adapted to the host community. Cotesia parasitoid wasps adapt to local lepidopteran species possibly through their symbiotic bracovirus.

PERHAPS it may interest your reviewer of Dr. and Mrs. Peckham's work “On the Instincts and Habits of the Solitary Wasps,” to learn that one of the main results in question has been already arrived at in a paper by the late Prof. Schiff, of Geneva, in Memoires de la Soc. de Physique et d'Histoire naturelle de Geneve, vol. xxviii., 1882–3.

What are figs and fig wasps? Figs are plants in the genus Ficus, which have a unique closed inflorescence called a syconium, typically containing hundreds of flowers. We eat the ripe syconia of one species, F. carica, and call these ‘pseudofruits’ figs too.
