Abstract
The aim of the present investigation was to extend a previous study, showing a correlation of the variations of hemolymph carbohydrates with synodic lunar-like cycle and its circaseptan harmonics to worker honeybee hemolymph lipids. Hemolymph lipid concentrations of emerging worker imagos were analyzed in terms of one ideal synodic lunar cycle and processed by the cosinor method testing the null hypothesis versus the presence of 29.5-, 14.8- or 7.4-day periods in the data. A rhythmicity statistically compatible with a 29.5-day rhythm was observed for triacylglycerols and steroids as well as for body weight. A circadiseptan rhythm was determined for 1,3 diacylglycerols, while fatty acids and phospholipids exhibited a circaseptan rhythm. An agreement of peaks for triacylglycerols, steroids and body weight at the new moon, but not at the full moon, was noted with respect to trehalose and glucose circadiseptan rhythms. The latter moon-phase timing of peaks and nadirs, compared with that previously determined for trehalose and glucose, appeared to be identical to the circadiseptan rhythm and reciprocal for the circaseptan rhythms of 1,3 diacylglycerols. Reciprocal tendencies in circaseptans of trehalose and glucose on the one hand, and fatty acids and phospholipids on the other are indicated. The underlying causal nexus of these relationships is unknown
