title: Structural changes in the salivary glands of Ixodes ricinus larvae.
abstract: The authors analysed the structure of Ixodes ricinus (L.) larvae in specimens immediately after leaving the egg sheaths, in those which have not fed for 2 months after hatching, and in feeding larvae on the second day of feeding. The results showed that salivary glands in tick larvae are formed by alveoli aligned in strands on both sides of the central nervous system. These alveoli open into central efferent ducts via short ducts. The constituent elements of salivary glands include pyramidal alveoli (with numerous lipid droplets) and granular alveoli of varied structure. It is worth noting that salivary alveoli containing secretory material are present even in the larvae which had just left egg sheaths and were still endowed with deutoplasm.
