Phenology of Hippodamia undecimnotata (Col.: Coccinellidae) in Greece
Entomophaga 42 (1/2), 283-293
Abstract: Hippodamia (Semiadalia) undecimnotata (Coleoptera: Coccinellidae), collected from central Greece and reared in cages during 1993-1994 and in vials during 1994-1995 outdoors at Kifissia, Athens, completed 5 generations per year. In both cases, adults of the 1st, 2nd and 3rd generations reproduced, completing their egg laying in the same year; 4th and 5th generation adults reproduced both in the year they emerged and the following year. In both cases, adults of the 1 st and 2nd generations died before winter; in 1993; adults of the 3rd generation died before winter, in 1994, they survived until April 1995. Adults of the 4th and 5th generations overwintered successfully. The greatest numbers of eggs were laid by female of the 1st and 2nd generations.
Field observations and timed counts of specimens (30 minutes per location) made on the tops of Mounts Chlomo and Kitheron and on the neighboring plain of Kopais between 1991 and 1994 revealed that most adults arrived on the mountains between late June and early September and left between the end of March and beginning of May. H. undecimnotata were not found on the plain of Kopais during the winter. Overwintered adults arrived between the end of March and beginning of May; 1st generation adults emerged in June. The presence of a few eggs, larvae, pupae and newly-emerged adults observed on the plain during August-September 1993 suggests that at least a portion of the H. undecimnotata population in central Greece completes 2 or more overlapping generations per year.
