Responses of groups of 3D worker honeybees (Apis mellifera) to bees affected with chronic bee paralysis, to intruder bees (healthy non-hivemates), and to healthy hivemates were monitored at 18'8,22'2,24'4,27'7 and 30·0oC. Temperature had little or no effect on antennal investigations of test bees. Bees with paralysis were investigated the most, intruders were investigated less, and hivemates were investigated least by caged bees at all 5 temperatures. Temperature had little or no effect on attack-response to intruders or hivemates, whereas attack-responses to bees with paralysis was affected by temperature. Seconds until attack decreased as temperature increased. Number of attacks, seconds under attack, maximum number of simultaneous attackers, and degree of attack increased with temperature. Effect of temperature on  non-stinging responses to bees affected with chronic bee paralysis is comparable to the effect of temperature on stinging behaviour. The fact that temperature affected response to bees with paralysis but did not affect response to intruders suggests that two different stimuli may elicit the similar behaviour patterns.
