Animal Behaviour, 1964
Abstract 1. 1. It is shown experimentally that locomotion is influenced by external contact. 2. 2. Thigmokinetic reactions are part of the behaviour pattern and distinct from humidity reactions though their effects may be similar. 3. 3. Thigmokinetic behaviour varies with the species and with relative humidity.

Cutaneous Respiration in Woodlice
Journal of Experimental Biology, 1955ABSTRACT Oxygen uptake and carbon dioxide output were measured in the woodlice Ligia oceanica, Oniscus asellus, Porcellio scaber and Armadillidium vulgare, in moist and in dry air, using normal animals and animals whose pleopods had been blocked by emulsion paint. In moist air, the rate of oxygen uptake which occurred through the general

Evidence for heterosis in woodlice
Journal of Genetics, 1962As analysis of Howard’s data on the genetics ofArmadillidium vulgare gives strong evidence in favour of the view that heterozygotes are generally more viable than homozygotes in early life.

THE structure and function of the rectal glands of insects have been investigated by several workers1. Later, Wigglesworth2 studied these glands more thoroughly in a number of species. No report, however, has yet appeared in the literature regarding the presence of rectal glands in woodlice (Crustacea : Isopoda), although Edney3 stated : “the faecal ...

SOME little time ago I published a note on the duration of life of certain species of woodlice1 which had been studied by Major Stanley S. Flower and me, and it was there recorded that Major Flower had kept a specimen of Oniscus asellus Linn, (born in captivity) for approximately 4 years 8 months and 28 days or possibly 4 years 9 months 20 days. My own

The Body Temperature of Woodlice
Journal of Experimental Biology, 1951ABSTRACT Measurements by means of thermocouples, accurate to 0.1° C., were made of the body temperature of the woodlice Armadillidium, Porcellio, Oniscus and Ligia, and of the cockroach Blatta, both alive and dead, in a stream of saturated or dry air at both 20 and 37° C.

Turn alternation in woodlice (Porcellio scaber)
Animal Behaviour, 1967Abstract It was shown that response alternation frequency in woodlice became higher with the number of prior forced turns in one direction, but was unaffected by varied distance between the start and a forced turn. However, the frequency became lower with increased distance between a forced turn and a choice point, and also with detention following a

IT is well known that in insects during the process of moulting or ecdysis there is a thin plasma or moulting fluid. "When the epidermal cells separate from the old cuticle and begin to secrete the new, the space between the two cuticles is occupied by a thin plasma.

Woodlice as material for research projects
Journal of Biological Education, 1980Abstract Woodlice are easy to obtain in large numbers, their biology is relatively simple, they are easy to culture, and the common species can usually be recognized with the naked eye: consequently they provide ideal material for student research projects.
