“…The (Chauvin, 1976), or a detection system using photoelectric cells (Brittain, 1933;Spangler, 1969;Burril and Dietz, 1973;Erickson et al, 1975;Buckley et al, 1978; Pickard and Hepworth, 1979;Rickli et al, 1989;Liu et al, 1990). Most Firstly, it appears well adapted for measuring normal colony activity (50 000 bees on 10 combs) and as such is comparable to the model proposed by Rickli et al (1989). This is certainly more interesting than the devices designed to monitor small colonies on only 1 comb (Spangler, 1969), 3 combs (Liu et al, 1990) or 5 combs (Erickson et al, 1975).…”

“…Next, earlier counters used 2 infrared beams and the detectors were fitted as closely together as possible, ie 2.5 mm (Rickli et al, 1989) and 5 mm (Liu et al, 1990). The present counter uses 1 infrared source and 1 dual photoreceptor containing the 2 detectors.…”

Summary — An important parameter in evaluating the activity of a honeybee colony is given by the number of bees leaving and entering the hive as a function of time. The microprocessor-controlled counter described here presents many advantages over previous counting devices. The counter fits the standard hive measurement (10 combs), and provides access to the hive via 32 bi-directional channels. The very small infrared detectors in each channel are only 0.1 mm apart, and are controlled by an asynchronous sequential algorithm, which improves the counter's precision. Results of measurements of the daily activity of honeybee colonies under different conditions (normal, in the presence of pesticides, or during swarming) are presented.Apis mellifera / bee counter / flight activity / swarming / pesticides INTRODUCTION

“…Several authors highlighted the importance to not interfere with the normal behavior of the bees in any way to collect legit and unbiased data (Fabergé 1943, Erickson 1975, Rickli et al 1989, Struye et al 1991, Chen et al 2012. Struye et al (1991) postulated the following requirements for a "stand-alone continuous monitoring field device": i) monitoring of all colony sizes, ii) no influence on normal bee behavior, iii) ventilation and orientation should not be compromised, iv) the device should work completely autonomous and under field conditions, v) user friendly and low maintenance construction, vi) the device should be affordable to monitor more than one colony and further vii) have a low energy consumption of the components to allow continuous operation.…”

For nearly 100 years, electronic bee counters have been developed using various technologies to track the foraging activity of mostly honey bee colonies. These counters should enable remote monitoring of the hives without disturbing natural flight behavior while generating precise scientific data. Today, however, there are not many counters on the market, that are able to fulfill this task. One main challenge is the lack of standardized methods to validate a counter's precision, but validation is crucial to categorize and judge the data produced by the counter, especially for scientific purposes. Another challenge is the interpretation of flight data to measure the effects of environmental or anthropogenic sources. Nevertheless, recent developments in the field are promising. This review describes the historic development of automated bee flight measurement and critically compares validation methods to encourage their improvement. Lastly, to increase the comparability of future analyses with bee counters, current advances in data interpretation are also presented.

“…Based on Brittain's system, several works have progressively improved the functioning of the apparatus (Kerfoot, 1966;Spangler, 1969;Burril and Dietz, 1973;Erickson et al, 1975). More recently, modern systems introduced electronic counters, the use of infra-red light sensors, two sensor couples to discriminate the direction of the bee movement, and computer data analyses (Marletto and Piton, 1983;Rickly et al, 1989;Liu et al, 1990;Struye et al, 1994). These devices were robust and adapted to outdoor conditions.…”

Behavioural methods to assess the effects of pesticides on honey bees

-We reported on the use of experimental procedures dealing with these behavioural skills in the assessment of pesticide effects. The relevance of the following methods are discussed: (1) use of automatic activity counters set at the hive entrance to establish the balance between outgoing and incoming worker bees; (2) observation of the homing flights of bees; (3) the analysis of the information encoded in the dances of returning foragers; and (4) recording of the conditioned proboscis extension response on restrained bees to evaluate individual learning performances involved in foraging behaviour. These behavioural assays could be developed for sublethal toxicity assessment. However, careful validation of the tests is needed before being used in a routine evaluation procedure. At a minimum, they are valuable tools to understand the mechanisms underlying insecticide toxicity.Apis mellifera / ecotoxicology / risk assessment / pesticide / behaviour
