Description
| - Diapause is an important period in the life-history of ladybirds as it lasts often about nine months, when the beetles do not feed and survive on energetic reserves. The adults enter diapause either spontaneously as a genetically fixed phase of life-cycle or are induced to it by environmental signals, mainly by the day-length that is the safest, as repeated every year with astronomical precision. It is stressed in the introduction that diapause is not a stand-stil but a process that has to be completed by diapause development. In the main subchapter the ecophysiological regulation is explained on the most common species, such as the sevenspot, Coccinella septempunctata, but the specific characters in other 18 species are also depicted. The next subchapter describes the specific behaviour patterns related to dormancy, particularly migration and aggregation in 20 ladybird species. The last subchapter deals with anatomical and physiological changes, with main stress on the condition of gonads, as controled by endocrines, and also the accumulation of reserves (lipids and glycogen) and the substances important for cold-hardiness (such as polyols and trehalose). In conclusion, the lacunes in knowledge are disclosed to stimulate further research.
