(B) PER conditioning assays. (1) Initial feed and water desensitisation. Harnessed bees given 3β5β ΞΌl 30% (w/w) sucrose; antennae touched with water. (2) Acclimatisation. 1β h in darkness (lab cabinet), 22β25Β°C, 35β40% relative humidity. (3) Conditioning. Five citral presentations (5β ΞΌl 95% v/v on filter paper in 20β ml syringe) each reinforced with 30% sucrose. (4) Filter. Discard bees showing PER to first odour presentation or no PER to sucrose. (5) Memory tests. Three trials same day+three trials next day. Group assignment: Good Learners=PER in all six tests; Poor Learners=no PER in any test. (6) Storage. Freezing at β80Β°C for later molecular work.

If youre looking for a conference this summer, join us at the IUSSI international Congress in Freiburg.
If you need somewhere to submit an abstract, some wonderful colleagues and I are hosting a symposium on Conserving Wild Social Insects. Take a look at the brief!

We are have updated our research into which garden plants attract the most pollinators. Our original research included 5 years of data. We then moved house so this is now 9 years of data over 2 different locations.

A brilliant week of citizen scientist pollinator identification training on for the participants of the Pollinator Pathmaker Constantine Network
Shout out to these hairy footed flower bees for being the tricky candidate for is it a solitary bee or bumblebee
In a new paper that I co-authored we suggest that #Biodiversity Net Gain may be falling short for some of the most vital, yet overlooked, members of our ecosystems: invertebrates.

Prepare yourself for a flurry of photos of pollinators this summer πΈπ

It's been great to get the plants in the ground over the last few days π§βπΎ

π’ New study: Insect Biomasse & abundance were similar in protected areas & urban wastelands, but πwild bee diversity was higher in urban areas! Protected areas (Natura 2000) may need targeted management to support pollinators.
