Apis mellifera has a form of communication that is distinct from all other eusocial insects. The ethological footprint experiment was structured over thirty-five days of observation on newly- fledged adult bees, marked and placed in an observation hive containing a single comb. The evolution of observed behaviours matched theoretical predictions. During the first few days of life, the bees gave their attention to brood care, then they devoted themselves to cleaning the hive and companion bees, and in the last period they engaged in foraging. Several types of dances were identified: the abdomen dance, the jerking dance and the circular dance. These dances carry messages about the specific location of the trophic resource, but are also important in communicating with the entire colony. A correlation was also found between the location of comb and dances; in this case 71% of the observed dances were performed near the hive entrance.
Apis mellifera ha una forma di comunicazione che si distingue da tutti gli altri insetti eusociali. L’esperimento di impronta etologica si è strutturato in trentacinque giorni di osservazione su api adulte neo-sfarfallanti, marcate ed inserite in un’arnia di osservazione contenente un singolo favo. L’evoluzione dei comportamenti osservati è stata in linea con le predizioni teoriche. Durante i primi giorni di vita le api hanno rivolto l’attenzione alla cura della covata, poi si sono dedicate alla pulizia dell’alveare e delle api compagne e nell’ultimo periodo hanno svolto attività di foraggiamento. Sono state individuate diversi tipi di danze: la danza dell’addome, quella sussultante e quella circolare. Queste danze portano dei messaggi circa la posizione specifica della risorsa trofica, ma servono anche a comunicare con tutta la colonia. È stata anche trovata una correlazione tra posizione del favo e le danze, nel nostro caso il 71% delle danze osservate sono state eseguite in prossimità dell’ingresso dell’alveare.

Abstract
Apis mellifera has a form of communication that is distinct from all other eusocial insects. The ethological footprint experiment was structured over thirty-five days of observation on newly- fledged adult bees, marked and placed in an observation hive containing a single comb. The evolution of observed behaviours matched theoretical predictions. During the first few days of life, the bees gave their attention to brood care, then they devoted themselves to cleaning the hive and companion bees, and in the last period they engaged in foraging. Several types of dances were identified: the abdomen dance, the jerking dance and the circular dance. These dances carry messages about the specific location of the trophic resource, but are also important in communicating with the entire colony. A correlation was also found between the location of comb and dances; in this case 71% of the observed dances were performed near the hive entrance.File | Dimensione | Formato | |
