  pages={193 - 195}
Group-living Collembola of the genus Hypogastrura coordinate their moulting by communication. Animals of different ages and moulting rhythms synchronized the moulting rhythms when combined in a single culture. This synchronization is apparently not dependent on external stimuli but is coordinated by chemical communication among these insects. 
Communication and synchronized molting in a colonial araneid spider,Eriophora bistriata
The colonial orb-weaving spider, Eriophora bistriata, coordinates molting cycles through communication, and the possible coordination of this synchrony by chemical communication among spiders is discussed.
1. Microarthropods (Acari and Collembola) are dominant components of the terrestrial fauna in the Antarctic. Their cold tolerance, which forms the mainspring of their adaptational strategy, is
Synchronized and rhythmical activity during the prey capture in the social spiderAnelosimus eximius (Araneae, Theridiidae)
The results are discussed with reference to the model developed by Goss and Deneubourg (1988) suggesting that autocatalysis may be the motor of certain synchronized and rhythmical activities in social arthropods.
Adaptive Molting Signal in a Gregarious Sawfly Larva, Perga affinis?
Observations of molting activity of the gregarious larvae of the Australian sawfly revealed that larvae were significantly more likely to molt during the day, while residing in tight clusters, than at night when they were dispersed.
Chemical communication in springtails: a review of facts and perspectives
Much more needs to be done before reaching straightforward conclusions about chemical communication issues at evolutionary and community levels, making this domain even more rewarding.
Jumping technique and climbing behaviour of the collembolan Ceratophysella sigillata (Collembola: Hypogastruridae)
Ceratophysella sigillata uses protrusible vesicles on its antennae and posterior end as sticky landing devices to avoid tumbling upon landing. This technique facilitates its orientated movement
Autocatalysis as a source of synchronised rhythmical activity in social insects
SummaryA model that generates synchronised rhythmical activity from autocatalytic behaviour followed by a rest period is presented and discussed with respect to social insects and group-living
Alarm Pheromone in a Gregarious Poduromorph Collembolan (Collembola: Hypogastruridae)
This is the first report on the presence of an alarm pheromone in the gregarious poduromorph collembolan, Hypogastrura pannosa, in the order Collembola, and it is reported thatpecifics encountering the vapor front respond with stereotypic aversion and dispersal behaviors.


Overland Migration of Collembola (Hypogastrura nivicola Fitch) Colonies
Dense aggregations of Collembola (Hypogastrura nivicola Fitch) move across the surface of the forest floor in central New England in the autumn and spring for distances of 20-25 m before
Further Experiments on the Effects of Social Factors on the Rate of Sexual Maturation in the Desert Locust
Males of the desert locust produce a pheromone when they are sexually mature which accelerates maturation of young males and virgin females, and the mature males used as activators in the experiments which established this fact were all reared during hopper and early adult life at high density.
The Insect Societies
The author wished to relate the three phases of research on insects and to express insect sociology as population biology in this detailed survey of knowledge of insect societies.
