“The devil is in the detail” is a saying often used to point to unexpected events in a process. In other words, one can say “success is in the detail”.
Welcome to INSIGNIA-EU, an exciting new pan-european citizen scientist study with beekeepers. The Mission statement of the is INSIGNIA -EU study is: “INSIGNIA-EU will extend the INSIGNIA pilot project (2019-2021) to encompass pan-European environmental pollution bio-monitoring using honey bee colonies. The main pillars are: 1) Robust data, generated by beekeeper citizen scientists via a clear bio-monitoring guideline (protocol), new simple and easy to handle sampling techniques and sample preservation methods, quality controlled sample analyses to low levels and professional data handling; and 2) Modelling of land use – related to environmental (established and emergent) pollutants, pesticide exposure risk for honey bees and pollen diversity.”.

At 6.40 h Dutch time, my pre-recorded presentation at the COLOSS Asia conference was on. I think the presentation was well-received, given the questions about the impact of the landscape on pesticides and details of pollen metabarcoding and protocol development.
To me it was a special experience, watching my presentation. I heard a strong Dutch accent, a lot of gesticulation with my hands, stumbling over complex word combination as “this coincides with the Covid pandemic” and too rapid speech. This despite my being aware of this when I recorded the talk. So, what you think about how things look and sound like, and how they look and sound is different… Nothing new, this wisdom is already as old as the world, but to me, it was good to be pressed with my nose on these facts, and a strong learning moment.
Although I would have loved to go to Japan to present INSIGNIA in person in the Asian world, I am a big fan of online conferences. However, what I miss in these online conferences is the chat with participants with a special interest in the subject. In the physical world, most information is exchanged during coffee and lunch in bilateral contacts, as not everybody is keen on raising their hand in public, which is fully understandable. Therefore one must develop these kind of chatroom talks or features after the meeting or during the lunch break.
The INSIGNIA study has been running now for two years and we are entering the final stage. In these two years, we have gone through all stages of organizing an apiculturist citizen science study. We developed the passive sampler APIStrip, the efficient matrix to capture pesticides, and all the pitfalls that came on the way like the “not-to-be -misinterpretable” label, best practice for storage shipping, sampling schemes etc. Now it is time to bring all of this information together in the “Guideline for apiculturist citizen science for applying honeybee colonies for bio-monitoring of the environment – subject pesticides”. Given the Covid-19 restrictions, physical meetings to discuss all of the stages, best wording, most logical set-up, best flow-charts, and whatever it takes to write the best guidelines, would be great but are sadly impossible. Therefore we have started a scheme of virtual Teams-meetings with a strict agenda to go through all of these aspects. We started in December 2020 and will be finished in March 2021. There will be as many Teams-meetings as it takes to get the job done in time.
In my virtual meetings with the beekeeper citizen scientists, I am asked sometimes: “what is in it for me?” A fair question. Let me explain what is in it for you… You will sample pollen and APIStrips from two colonies on ten occasions. Pollen and APIStrips will be analyzed at the apiary level; pollen for botanical identity and the APIStrips for pesticide residues in the hive. These results will be shared with you and will give you the information about what plants your bees have collected pollen from, and what pesticides your bees have brought along with the pollen and nectar. The latter is qualitative, meaning yes/ no pesticide present in the APIStrip. We detect different amounts but what this means for the actual exposure of your bees in the hive can’t be told with these data. This requires another study set-up which hopefully can be done in the future. Now the reward in monetary terms. Each APIStrip with its analysis costs about €200 each, and each pollen analysis also costs about €200. So together this is €400, with transport, administration, quality control, statistics and reports not included. A very cautious estimate of the costs per beekeeper for Insignia will be 10 sampling x € 400 plus extra costs = €4,500. 60% of this is paid by the European Union = € 2,700, the remainder €1,800 is paid by your national coordinator’s institute and you will have this information about your bees for free.

Today, the first APIStrips were removed after a 14-days exposure period. Curious to see if the APIStrips absorbed pesticides in detectable amounts. Also, the first pollen was taken from the pollen pots. Relying on the purple pollen color, I think the bees foraged among others on the horse chestnut (Aesculus spp.) and/or red deadnettle (Lamium purpureum). Alice and her team in Bragança will tell after the metabarcoding analysis. The APIStrips and pollen are labeled and stored in the freezer until shipping to the labs.
Next to the honeybees, the bumblebees are part of the Insignia study. This year we are testing the pesticides, collected by bumblebees in the field along with pollen and nectar, with the APIStrip. I will work this year with two colonies at the Sinderhoeve, the experimental station of Wageningen University, Environmental Science in Heelsum. Bumblebees are blind for the longer wavelength light spectrum, therefore, manipulation of the colony is done in red light. This keeps them rather calm. Bumblebees do not have beelanes, actually, compared to honeybees their brood nest is a mess. But, as honeybees, they are very curious. To prevent disturbance of the colony during changing the APIStrip, I inserted the strip via the top- grid near the entrance of the bumblebee box positioned in the very proximity of the brood cells. On the reddish photo you see them crawling over the APIStrip (with the black tyrap). Box entering and box- leaving bumblebees will be in contact with the strip as will the in-box bees. Time will learn whether the APIStrip will be incorporated in the brood nest or left apart in the 2-weeks exposure period. In two weeks the first APIStrips will go out and the second will go in, simultaneously to the honeybee colony sampling. Therefore, two photos of reddish. The APIStrip is prevented from falling into the box by a tyrap. Let’s follow how it will go in the next six weeks.
Meetings as the annual plenary meeting are about more than data exchange and scientific discussion; they are also about meeting colleagues, social interaction, interests in colleague’s family life and relaxation in eating and drinking together. The early birds that arrived already on Sunday 12th January were invited for a tapas experience in Almeria city and both meeting evenings were great experiences with Spanish fish meals, regional culinary highlights, Spanish wine, and Portuguese port. In the coffee- and lunch breaks there was time for chats in the sun. This socializing, chatting and having a good time is the basis for mutual respect which, together with full commitment to the well-being of the honeybee and the interests in the environment and its interaction with the bees, form the fundament for a good functioning team; and a good functioning team we are!
At the University of Almeria, Amadeo Fernandez-Alba and his team hosted 24 scientists from 10 countries for the plenary Insignia meeting on 14th and 15th January 2020. In a great ambiance, the results of the 2019 study were presented, discussed and comprised into the 2020 protocol, to be tested in 9 countries in 81 apiaries. The results presented clearly showed a difference between the four (4) pesticide residue matrices, the two biological matrices: trapped pollen, beebread, and the two non-biological non-invasive passive sampling matrices: Beehold tube and the in-hive APIStrip. The latter proved to have the best binding capacities for the number of pesticides. Trapped pollen proved to be a very poor matrix for this purpose. Beebread and the Beehold tube functioned in between. For pollen diversity, three matrices were tested: trapped pollen, beebread, and the Beehold tube. Comparison between classic microscope palynology and ITS2 pollen metabarcoding revealed that ITS2 pollen metabarcoding results are comparable outcomes on family level. For pollen diversity, the three (3) matrices gave similar results. Based on the 2019 results it was decided to apply in the 2020 study the best pesticide residue matrix APIStrip and the most practical pollen matrix: trapped pollen for ITS2 metabarcoding. Insignia is about protocol development for citizen science study. The interaction between scientist and apiculturist has been studied in a sociological study. Non surprisingly it can be concluded that citizen scientist involvement is based on personal interests like participating in a scientific study or interest in the environment primarily on mutual respect between the scientist and beekeeper and mutual concern for the well-being of the honeybee.
All the aspects, from the interaction between scientist and beekeeper and instruction workshops to practical issues as best exposure location, matrix storage, and transport were point by point discussed and agreed. This will result in an updated instruction/ picture manual for all participating beekeepers.
Last week note nr 2. “Follow your scientist – the INSIGNIA project” by Flemming Vejsnæs was sent out to the stakeholders. it draws the attention to our social media and website to inform and to enhance the cooperation and commitment of the stakeholders to the INSIGNIA project. Soon similar notes will be sent to the beekeeper’s journals in the INSIGNIA countries. More notes will follow
