Strange news.

Who sprays trees and why?

In the picture there is Tilia. Its nectar kills naturally emormous amout of bumblebees.


Only what you can do is collect money for bumble ceremoni and fill money into yourt pockets

They were spraying linden trees for aphids. Unfortunately, the pest control company that did the work didn't follow application guidelines and sprayed the trees when they were in bloom.

:?  Where did you come up with this information?  What component of the nectar is bad for the bumble bees?

Abstract

The Foraging Behaviour of Honeybees and Bumblebees on Late Blooming Lime Trees (Tilia spec) 2007

The dying of bumblebees under the late flowering lime tree Tilia tomentosa has been described by several authors. The flowers produce high quantities of non-toxic nectar, and honeybees as well as bumblebees forage on this source. However, only numerous dead bumblebees are found under silver linden trees. In this study the foraging pattern of honeybees and bumblebees on early and late blooming lime trees was compared. Flower visity, nectar availability and the fallout of dead bees was recorded over the course of the day and also during the entire blooming period. Honeybees foraged on T tomentosa only at times of high nectar availability. Bumblebees however visited the trees throughout the flowering season, especially at the beginning, but continued also after decline of nectar production. The different foraging strategies of Bombus and Apis bees are discussed and may explain the phenomenon of dying bumblebees.
