How do #animals #aggregate?#Mites can find each other based on #pheromones, while #sight is important for herd-forming #mammals. In #marine #habitats, #hearing plays a major role. D.McAfee et al.(2022) showed that #oyster #larvae react to the #soundscape of a healthy #reef via #statocysts in front of their bodies, thus finding their adult conspecifics for #reefformation. Reef formation can be artificially #stimulated via artificial #soundwaves.

2/2 be found sunbathing on stones, and tree trunks. They love #climatechange and wander slowly northwards.

Gardeners, who don't like them, can prevent nymphae becoming adult by talking to them ... via the pheromones of Abies balsamea wood chips. Their scent, the #Juvabione, mimicks the juvenile hormone of firebugs. But why should one do this!

In #Astigmata #mites #chemosensitive/#tactile interactions take precedence over #visualsenses. #Histiostomatidae (here, #Histiostoma sp., H. feroniarum complex, ex #rottinglemons, #Italy) communicate using various #pheromones/allomones produced by the #opisthonotal #glands. See here a #glandularopening on the upper hindbody #(hysterosoma) of a #female, #SEM.

New findings shed light on how #BellaMoths use #poison to attract mates

What one genus of showy moths can say about migration, adaptation, and wing pattern https://www.pnas.org/doi/10.1073/pnas.2319726121

"These day-flying #moths exclusively eat the #alkaloid-laden leaves and seeds of rattlebox #plants. They then use the toxin to guard their eggs and deter predators in later life stages. They even use it to make #pheromones that attract mates."

Exposure to #female #odors and #pheromones causes #weight loss and extend the life spans of mice, which may have implications for #humans, University of Otago researchers have found.

#Exposure to high levels of #ozone significantly #increases #MaleMale #courtship among #FruitFlies while making the #OzoneExposed #males #LessAttractive to #females finds a #NewStudy . 

As #OzoneLevels rise due to #industrial #pollution & #anthropogenic activities, it can #harm a number of #species of #insects that rely on #SexDetermining #pheromones to find a suitable mate, it added.

Genetically encoded calcium indicators are becoming available in social insects.
After the first expression in honeybees (https://www.biorxiv.org/content/10.1101/2022.04.22.489138v2), now the first GCaMP-expressing ants have been created and used to study the coding of alarm pheromones in the antennal lobe.
