Is the spider a good biological control agent for Plutella xylostella (Lepidoptera: Plutellidae)?

open access: yesZoologia (Curitiba), 2018
Spiders, as predators of insects and other invertebrates, are an important part of the natural enemies, and they are recognized as an important biological control agent.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

open access: yesAdvanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Regional variation of habitat tolerance by some European spiders (Araneae) - a review [PDF]

open access: yes, 2009
The data presented by HÄNGGI et al. (1995) and BOLAÑOS (2003) on the habitats of a large number of European spiders are examined, most of which appear to show non-specific preferences.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

open access: yesAdvanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Chemically Regulated STING‐Activating Prodrugs of Deoxyribose Cyclic Dinucleotides Elicit Robust Immune Activation and Durable Antitumor Immunity

open access: yesAngewandte Chemie, EarlyView.
All three diastereoisomers of an esterase‐sensitive phosphotriester dCDN prodrug demonstrate improved activity. The (Rp,Rp) diastereoisomer shows the highest activity with an EC50 of 1.7 nM in STING activation and displays the most pronounced antitumor activity via intravenous administration, significantly suppressing tumor proliferation, extending the

Learning in Spiders [PDF]

open access: yesAmerican Zoologist, 1969
After the spider, Zygiella x-notata Cl. has been enticed to leave the retreat and catch a fly in a web turned upside-down, it takes a relatively long time to return to the retreat. The return-time is divided into periods of active searching and motionlessness.

TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens

open access: yesAdvanced Science, EarlyView.
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.
