Citizen science is a powerful tool for connecting members of the public with research and for obtaining large amounts of data. However, it is far less commonly implemented in developing countries than in developed countries. We conducted a large‐scale citizen‐science program monitoring honey bee (Apis mellifera) colony losses in Argentina to examine how a national consortium composed of local coordinators and two different recruitment strategies influenced volunteer participation. These strategies consisted of online questionnaires and face‐to‐face interviews with beekeepers to record bee health issues. We found that use of both recruitment strategies was necessary because they reached different volunteer profiles and different locations, and therefore influenced the survey's results. Furthermore, public participation increased when the number of local coordinators was higher, regardless of recruitment strategy. These findings could also apply to other developing countries, where lack of internet access for some potential volunteers, logistical constraints such as long distances, and poor infrastructure hamper implementing large‐scale citizen‐science programs.

“…На сьогоднішній день учасниками міжнародного моніторингу є 29 країн світу (переважно північної півкулі) і кількість їх щороку зростає. Україна долучилася до міжнародного моніторингу COLOSS у 2015 р. і два роки надає дані, що поряд із даними інших країн слугують для встановлення регіонів підвищеної смертності бджіл та виявлення найкращих практик бджільництва (Brodschneider et al, 2016).…”

“…Для розуміння ситуації в Україні на міжнародному тлі, зауважимо, що середній показник втрат бджолиних колоній після зимівлі 2015-2016 рр. на території країн-учасниць міжнародного моніторингу становив 12,0 %, що також майже у 1,5 рази нижче відповідного показника попереднього року (17,4 %) (Brodschneider et al, 2016). На величезній вибірці респондентів встановлено, що найбільших втрат бджолосімей зазнала Ірландія (29,5 %) та Північна Ірландія (28,2 %), після яких -Уельс (22,4 %) та Іспанія (22,1 %); найнижчі ж показники втрат виявлено в Чеській республіці (6,4%) і центральній Європі в цілому.…”

“…Докладніший аналіз може виявити вплив інших важливих факторів, таких як вплив кліща Varroa та ін. (COLOSS…, 2017;Brodschneider et al, 2016). Цієї зими всеєвропейська програма нагляду, що проводилась в 17 країнах, констатувала зимову смертність на основі польових досліджень в діапазоні від 4,7% до 30,6% в різних країнах (Chauzat et al, 2016).…”

Increasing of honey bee colony losses is considered to be a global threat to the planet's ecosystems, food security and global economy (Neumann & Carreck, 2010;van der Zee et al., 2012;van der Zee et al., 2014;Chauzat et al., 2016). A large-scale study of this phenomenon using the standard protocol is conducted by the international honey bee research association COLOSS.Ukraine has been providing the data since 2015. Honey bee (Apis mellifera L.) colony losses in Ukraine after the winter of 2015-2016 have been analyzed according to the physiographic zones of the country. It has been established that the total loss (the sum of the dead colonies and the colonies lost due to the unsolvable queen problems) after the winter of 2015-2016 was 9.9%, which is 1.5 times lower compared to the winter of 2014-2015 (14.9%). The losses due to colonies death decreased (6.3% after the winter of 2015-2016; 13.4% after the winter of [2014][2015], while the losses due to the unsolvable queen problems increased (3.6% after the winter of 2015-2016; 1.6% after the winter of [2014][2015]. The overall loss rate of 12.0% was recorded for the countries participating in the international COLOSS monitoring after the winter of 2015-2016, therefore Ukraine is considered to be the region with the comparatively low risk. Small apiaries had a significantly higher loss rate than medium and large ones. The highest loss rate was noticed in the zone of mixed forests, whereas it was the lowest in the deciduous forest zone. The majority of the respondents (44.4%) from the mixed forest zone, where the loss due to the unsolvable queen problems reached the largest scale, noted that the problems with the queens after this winter were more serious than usual, and wintering of the colonies with new queens was better, than with the old ones (83.3%). 64.4% of respondents conducted monitoring of Varroa infestation level of their colonies, and 82.5% treated the colonies against Varroa. The correlation between the use of some chemical and biotechnical methods against Varroa (lactic acid, amitraz, formic acid, hyperthermia, etc.) and losses due to both colonies death and unsolvable queen problems was revealed. It has been shown that queen replacement before winter contributes to lowering winter mortality (r = -0.18).

“…Other changes in colonies in North County Dublin have been observed over the period; more drones and more drone brood are located towards the centre of the brood nest, and colony winter mortality has declined from 15.8 to 11.2%, 2014-2017 using COLOSS data extracted for the North County Dublin region. The mortality rate for Ireland as a whole in 2015/16 was 29.5% (Brodschneider et al, 2016). Typically throughout the beekeeping world the initial infestation by the varroa mites resulted in rapidly increasing mite populations, sometimes dramatic, leading to a collapse of the colony (Büchler, 1994).…”
