“…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).…”

“…Earlier models had a very variable number of in/out channels: 2 (Spangler, 1969), 4 (Liu et al, 1990), 7 (Erickson et al, 1975), 11 (Marletto and Piton, 1983), 12 (Burill and Dietz, 1973;Buckley et al, 1978), 16 (Rickli et al, 1989) and 24 (Peyron et al, 1990). …”

“…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

“…Além disto, podemos ver que a atividade de vôo de P. remota em dias chuvosos dos meses mais frios (outono e inverno) foi bem diferente da atividade de vôo em dias não chuvosos das mesmas estações. Liu et al (1990) relataram que o número de vôos de A. mellifera em um dia chuvoso foi cerca de 20% do número de vôos em um dia ensolarado. Souza et al (2006) observaram que a menor atividade de vôo de forrageiras de Melipona asilvai ocorreu no mês mais chuvoso entre os dez meses de estudo.…”

Through an automated system, foragers' flight activity of four colonies of Plebeia remota was registered simultaneously from December 1998 to December 1999. The large amount of data obtained has allowed a quantitative and seasonal analysis of the rain impact on the bees' flight activity. The colonies came from two different localities: Cunha, Atlantic Rainforest in São Paulo State and Prudentópolis, Araucaria Forest in Paraná State. Percent numbers related to the flight activity for the moment that preceded the rain in one hour, as well as during and after the precipitation are presented. In all colonies, it was observed that the flight activity of P. remota has predominantly decreased before and during the precipitation. After it stopped raining, there was a predominance of increases, what indicates a compensation of flight activity in relation to the rainy period. In general, the greatest decrease of flight activity before rain, occurred in the autumn and the greatest increase of flight activity after rain, occurred in the spring. Alterations in this activity were observed with the variation of intensity, frequency and duration of precipitation. The external activity was little modified when the precipitation was up to 1.0 mm. However, when the rain intensity increased, the bees reduced strongly their flight activity. When the rain occurred only once per day, the decreases in the flight activity were greater, when compared to intermittent rain. Rains that lasted more than one hour caused larger decreases in the flight activity than precipitations of short duration. Flight activity was quite different when we compared days with rain and days without rain, as well as, flight activity was differently influenced in rainy days in the summer and in the winter. However, this behavior (response of flight activity to rain) did not allow to discriminate both populations.Keywords: flight activity, stingless bees, climatic factors, rain, foraging. Através de um sistema automatizado, a atividade do vôo de forrageiras de quatro colônias de Plebeia remota foi registrada ao mesmo tempo, de dezembro de 1998 a dezembro de 1999. Havia uma quantidade grande de dados que permitiram uma análise quantitativa e sazonal do impacto da pluviosidade sobre a atividade de vôo. As colônias vieram de duas localidades diferentes: Cunha, Mata Atlântica de São Paulo e Prudentópolis, Mata Araucária no Paraná. Números percentuais referentes à atividade de vôo para o momento que antecedia em uma hora a chuva, como também durante e após a precipitação, são apresentados. Em todas as colônias observaramse, predominantemente, decréscimos na atividade externa de P. remota, tanto antes como durante a precipitação. Após cessar a chuva, houve um predomínio de acréscimos, o que indica uma compensação da atividade de vôo em relação ao período chuvoso. De modo geral, o maior decréscimo de atividade de vôo, antes da chuva, ocorreu no outono e o maior acréscimo de atividade de vôo, depois da chuva, ocorreu na primavera. Alterações nesta atividade foram observa...

-Monitoring physical variables associated with honeybee colonies, including weight, temperature, humidity, respiratory gases, vibration, sound, and forager traffic, in a continuous manner is becoming feasible for most researchers as the cost and size of electronic sensors decrease while their precision and capacity increase. Researchers have taken different approaches to collecting and analyzing the resulting datasets, with a view toward extracting information on colony behavior and phenology. The objective of this review is to examine critically the different kinds of data and data analyses, providing researchers with better-informed options for obtaining information on colony phenology in the field without disturbing the hive, and for combining information from different kinds of sensors to obtain a more complete picture of colony status. Wireless sensor networks and powering sensors are briefly discussed.continuous hive weight / colony temperature / colony humidity / forager traffic / hive vibration
