[Characteristics of basic phenoperiods of fleas--parasites of small and mountain susliks in the Northern Caucasus].
For the fleas of sousliks of the North Caucasus, whose imagoes are in nature throughout a year, the authors identify three phenoperiods: 1) a phenoperiod of gonotropic activity (in fleas that have two generations, it consists of a phenophase of multiplication of second-generation imagoes of a previous year and of that of multiplication of first-generation imagoes of a current year; 2) a phenoperiod of preparation for gonotropic hibernation; 3) a phenoperiod of gonotropic hibernation. In the fleas that exist as imagoes for a short period of a year, in spring and summer, the authors single out two phenoperiods: imaginal and preimaginal that consists of a phenophase of flea existance at the stages of metamorphosis and a phenophase of imago cocooning.
