Hatching of the Egg of Ixodes ricinus L.

Abstract

THE mechanism of hatching in the sheep tick does not seem to have been previously described. When freely laid, the eggs are oval, but deposition in crevices results in a certain amount of flattening. Examination of the egg under the microscope reveals that the brown colour is due to a thin semi-transparent shell, covering the brown internal mass. Each egg is surrounded by a gelatinous secretion produced by Gené's organ. Immediately after oviposition., the individual egg weighs 0·00006 gm.
