Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
Insect Science, EarlyView.Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Aphid sex pheromone components: age-dependent release by females and species-specific male response
, 1990 Sex pheromone released by Megoura viciae oviparae was collected and analysed for the quantity and re-lative amounts of each of the two biologically active compo-nents.

Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

A New Mobility Model for Multi-UAVs Reconnaissance Based on Partitioned Zone
Applied Sciences, 2019 Activities on Unmanned Aerial Vehicle (UAV) have increased over the last years and there are many fields in which UAVs can be used. One of the basic applications is reconnaissance of a given area using multiple UAVs.

, 2007 Field-trapping experiments with synthetic 2,7-nonadiyl dibutyrate, the female-produced sex pheromone of the orange wheat blossom midge, Sitodiplosis mosellana (Gehin), demonstrated that pheromone traps were highly attractive to males and caught very few ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone
Insect Science, EarlyView.We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Sex-specific processing of social cues in the medial amygdala
eLife, 2014 Animal–animal recognition within, and across species, is essential for predator avoidance and social interactions. Despite its essential role in orchestrating responses to animal cues, basic principles of information processing by the vomeronasal system ...

New pheromone components of the grapevine moth Lobesia botrana [PDF]
, 2005 Analysis of extracts of sex pheromone glands of grapevine moth females Lobesia botrana showed three previously unidentified compounds, (E)-7-dodecenyl acetate and the (E,E)- and (Z,E)-isomers of 7,9,11-dodecatrienyl acetate.

Insect Science, EarlyView.In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Neural mechanisms of social learning in the female mouse
eLife, 2017 Social interactions are often powerful drivers of learning. In female mice, mating creates a long-lasting sensory memory for the pheromones of the stud male that alters neuroendocrine responses to his chemosignals for many weeks.
