Miller ABSTRACT The parasitic wasp Cotesia congregata suppresses feeding in its host, the caterpillar Manduca sexta , during specific periods of wasp development. We examined both feeding behaviour and the neurophysiology...

The proximate mechanisms of behavioural phase polyphenism have been well studied in the desert locust Schistocerca gregaria and the migratory locust Locusta migratoria , and what is known in these species is often treated as a general...

...Svante Winberg; Lynne Sneddon ABSTRACT Dominance-based social hierarchies are common among teleost fishes. The rank of an animal greatly affects its behaviour, physiology and development. The outcome of fights for social dominance is affected by heritable factors and previous social experience...

...-changing animals show mitigations, such as avoiding colour change when possible. We discuss the potential implications of this cost on colour change, behaviour and evolution of colour-changing animals, generating testable hypotheses and emphasising the need for future work to address this gap...

.... Behavioural experiments are essential for understanding animals' perception but are often challenging and time-consuming; therefore, using species that can be trained easily for complex tasks is advantageous. Picasso triggerfish, Rhinecanthus aculeatus , have been used in many behavioural studies...

... of individual signals. This different form of colour detection has been used to explain previous behavioural tests in which low-saturation blue was not discriminated from grey, potentially because of similar activation patterns. Results here, however, indicate that the stomatopod Haptosquilla trispinosa...

... remain unstimulated outside the chamber. Results show that the stimulation of a single leg with chemicals, such as disaccharides, is sufficient to trigger a complex search behaviour involving locomotion coupled with the reflex activation of antennules and maxillipeds. This technique can be easily adapted...

Non-eusocial bees are understudied with respect to foraging strategies and decision making, such as flower preferences. Understanding whether...

...Cosima S. Porteus; Christina C. Roggatz; Zelia Velez; Jörg D. Hardege; Peter C. Hubbard ABSTRACT In the past decade, many studies have investigated the effects of low pH/high CO 2 as a proxy for ocean acidification on olfactory-mediated behaviours of marine organisms. The effects of ocean...

In this way floral humidity can add to the information provided by flowers and could impact pollinator behaviour more significantly than previously thought. Our results indicate...

The present study is the first to assess visual opsin genetics in the ocellate river stingray ( Potamotrygon motoro ) and test whether individuals perceive colour in two alternative forced...

... flagellomeres appear rich in trichoid and grooved sensilla, known to be associated with olfactory functions. Through an RNAi approach, topically delivered HhTAR1 dsRNA induced a 50% downregulation in gene expression after 24 h in H. halys 2nd instar nymphs. An innovative behavioural assay revealed that HhTAR1...

Herein, we examined the substrate use, adhesive performance and vertical clinging behaviour...

In particular, tyramine (TA) and octopamine (OA) and their associated receptors orchestrate physiological processes such as feeding, locomotion and metabolism. Here, we show that monoterpenes not only act as biopesticides in Drosophila species but also...

Thus far, this high-speed sensory motor control has been extensively studied in relation...

The behavioural differences behind this discrepancy remain elusive, and are the subject of ongoing investigations. Here, we show that the two species demonstrate...
