Role of Olfactory and Visual Cues in the Attraction/Repulsion Responses to Conspecifics by Gregarious and Solitarious Desert Locusts

TLDR
This study analyzes the role of visual and olfactory stimuli in triggering different responses to conspecifics in isolation- and crowd-reared locusts, and the sensory and neurological mechanisms underlying these responses will form the basis for neurobiological investigations of locust phase.
Sensory Cues Involved in Social Facilitation of Reproduction in Blattella germanica Females
TLDR
Results show that tactile cues are the primary sensory input associated with social conditions—with no evidence for involvement of the visual and olfactory systems—and that the antennae play an important role in the reception of these tactile cues.
Mechanosensory-induced behavioural gregarization in the desert locust Schistocerca gregaria
TLDR
The data show for the first time that the gregarizing signal combines both exteroceptive and proprioceptive components, which travel in both nerves 5B1 and 5B2, and provides a powerful experimental method with which to elicit and study neuronal plasticity in this system.
Pheromones in relation to aggregation and reproduction in desert locusts
TLDR
Recent progress, contradictory results and perspectives in desert locust pheromone research related to reproduction are summarized and discussed in this paper.
Phenylacetonitrile is a male specific repellent in gregarious desert locusts, Schistocerca gregaria
TLDR
Results are in agreement with recent studies showing that this male specific pheromone is employed by mature gregarious males in sexual behaviour and acts as a courtship inhibiting peromone.

Sex differentiation studies relating to releaser aggregation pheromones of the desert locust, Schistocerca gregaria
TLDR
Antennae of the older adults showed significantly higher EAG responses than those of fifth instar nymphs to all four volatile collections, of which volatiles from older adult males were the most stimulatory and evoked the highest EAG amplitudes.
The influence of environmental microstructure on the behavioural phase state and distribution of the desert locust Schistocerca gregaria
TLDR
It is shown that the fine‐scale distribution of food plants, perches and favourable microclimatic sites influences the spatial distribution of locusts, both in the laboratory and under semi‐field conditions.
A Gregarizing Factor Present in the Egg Pod Foam of the Desert Locust Schistocerca gregaria
TLDR
Foam plugs of egg pods from crowd-reared, gregarious locusts contain a small (<3 kDa), hydrophilic gregarizing factor which is produced at the time of oviposition and which predisposes hatchlings to attain characteristics of the gRegarious phase.
LABORATORY EXPERIMENTS ON GREGARIOUS BEHAVIOUR IN OVIPOSITING FEMALES OF THE DESERT LOCUST, (SCHISTOCERCA GREGARIA (FORSK.))
TLDR
Females of the Desert Locust have a strong tendency to lay their egg‐pods in close proximity to each other and when females ready to oviposit wander into such a group they are stimulated to probe and to remain there until oviposition has occurred.
Antennal lobe interneurons in the desert locust Schistocerca gregaria (Forskal): Processing of aggregation pheromones in adult males and females
TLDR
Physiological and morphological characteristics of antennal lobe interneurons in male and female Schistocerca gregaria were studied by using intracellular recording and staining techniques and two spike sizes in the recording were correlated with two stained neurons in the antennals, suggesting electrical coupling of the neurons.
Analysis of phase-related changes in behaviour of desert locust nymphs
An assay is developed in which the behavioural responses of an individual locust to a group of conspecifics are used to derive an index representing the ‘behavioural phase status’ of that insect. The
An analysis of the behavioural effects of crowding and re‐isolation on solitary‐reared adult desert locusts (Schistocerca gregaria) and their offspring
TLDR
Investigation of the time‐course of behavioural change in response to crowding and re‐isolation in adults of Schistocerca gregaria Forskål found that females, through their previous experience of crowding, are effectively predicting the probability that their offspring will emerge into a high‐density population, and predisposing their hatchlings' behaviour accordingly.
