“…For this reason, we furthermore only used data when pairings of readings of the first and second scanners matched. Based on our own observations, a foraging trip was defined as a bee being outside the hive for more than 180 s. This includes bees on a short mission as defined by Susanto et al (). Onset of foraging was defined as follows: when a bee left the hive for two trips on one day, this day was counted as day of initiation of foraging.…”

Honeybees Apis mellifera and other pollinating insects suffer from pesticides in agricultural landscapes. Flupyradifurone is the active ingredient of a novel pesticide by the name of ‘Sivanto’, introduced by Bayer AG (Crop Science Division, Monheim am Rhein, Germany). It is recommended against sucking insects and marketed as ‘harmless’ to honeybees. Flupyradifurone binds to nicotinergic acetylcholine receptors like neonicotinoids, but it has a different mode of action. So far, little is known on how sublethal flupyradifurone doses affect honeybees. We chronically applied a sublethal and field‐realistic concentration of flupyradifurone to test for long‐term effects on flight behaviour using radio‐frequency identification. We examined haematoxylin/eosin‐stained brains of flupyradifurone‐treated bees to investigate possible changes in brain morphology and brain damage. A field‐realistic flupyradifurone dose of approximately 1.0 μg/bee/day significantly increased mortality. Pesticide‐treated bees initiated foraging earlier than control bees. No morphological damage in the brain was observed. Synthesis and applications. The early onset of foraging induced by a chronical application of flupyradifurone could be disadvantageous for honeybee colonies, reducing the period of in‐hive tasks and life expectancy of individuals. Radio‐frequency identification technology is a valuable tool for studying pesticide effects on lifetime foraging behaviour of insects.

“…This is a desirable outcome as it confirms the system is robust to misreadings (i.e., bees passing by antennas and not being detected). Misreadings in RFID systems can be caused by several factors including distance between the RFID tag and the antenna, power shortages, and inappropriate duty cycle set up ([ 10 ], and references therein).…”

“…Success rate in detection are reported to vary considerably (e.g., [ 3 , 6 , 7 , 8 , 9 ], and references therein). A recent approach proposes methods to address misreadings of RFID detections using data from the entire cohort of bees fitted with those devices to infer individual behaviour [ 10 ].…”

This paper introduces both a hardware and a software system designed to allow low-cost electronic monitoring of social insects using RFID tags. Data formats for individual insect identification and their associated experiment are proposed to facilitate data sharing from experiments conducted with this system. The antennas’ configuration and their duty cycle ensure a high degree of detection rates. Other advantages and limitations of this system are discussed in detail in the paper.

“…The time a drone spent outside the hive was the time span between a recorded “Departure” and a subsequent “Arrival” of the same individual. The time spans obtained were categorized based on Susanto et al (2018) [ 32 ] ( Table 1 ). During the categorization we made the following assumptions: If the drones leave and enter the hive frequently, i.e., between 1 s and 3 min, they are exiting to defecate or beard (see Figure 2 ) and entering to feed.…”

Males in Hymenopteran societies are understudied in many aspects and it is assumed that they only have a reproductive function. We studied the time budget of male honey bees, drones, using multiple methods. Changes in the activities of animals provide important information on biological clocks and their health. Yet, in nature, these changes are subtle and often unobservable without the development and use of modern technology. During the spring and summer mating season, drones emerge from the hive, perform orientation flights, and search for drone congregation areas for mating. This search may lead drones to return to their colony, drift to other colonies (vectoring diseases and parasites), or simply get lost to predation. In a low percentage of cases, the search is successful, and drones mate and die. Our objective was to describe the activity of Apis mellifera drones during the mating season in Northwestern Argentina using three methods: direct observation, video recording, and radio frequency identification (RFID). The use of RFID tagging allows the tracking of a bee for 24 h but does not reveal the detailed activity of drones. We quantified the average number of drones’ departure and arrival flights and the time outside the hive. All three methods confirmed that drones were mostly active in the afternoon. We found no differences in results between those obtained by direct observation and by video recording. RFID technology enabled us to discover previously unknown drone behavior such as activity at dawn and during the morning. We also discovered that drones may stay inside the hive for many days, even after initiation of search flights (up to four days). Likewise, we observed drones to leave the hive for several days to return later (up to three days). The three methods were complementary and should be considered for the study of bee drone activity, which may be associated with the diverse factors influencing hive health.
