TLDR
The current literature on stingless bee-agrochemical interactions is reviewed and the underlying mechanisms involved in reported stress symptoms, as well as the potential consequences based on the peculiarities of these pollinators are discussed.Abstract:
The toxicological stress induced by pesticides, particularly neonicotinoid insecticides, and its consequences in bees has been the focus of much recent attention, particularly for honey bees. However, the emphasis on honey bees and neonicotinoids has led to neglect of the relevance of stingless bees, the prevailing pollinators of natural and agricultural tropical ecosystems, and of other agrochemicals, including other pesticides and even leaf fertilizers. Consequently, studies focusing on agrochemical effects on stingless bees are sparse, usually limited to histopathological studies, and lack a holistic assessment of the effects of these compounds on physiology and behavior. Such effects have consequences for individual and colony fitness and are likely to affect both the stingless bee populations and the associated community, thereby producing a hierarchy of consequences thus far overlooked. Herein, we review the current literature on stingless bee-agrochemical interactions and discuss the underlying mechanisms involved in reported stress symptoms, as well as the potential consequences based on the peculiarities of these pollinators.read more

Glyphosate is lethal and Cry toxins alter the development of the stingless bee Melipona quadrifasciata.
Vanessa Eler Seide,Rodrigo Cupertino Bernardes,Eliseu José G. Pereira,Maria Augusta Pereira Lima +3 more
TL;DR: The proteins Cry1F, Cry2Aa, and the herbicide glyphosate were highly toxic to the stingless bee M. quadrifasciata, causing lethal or sublethal effects which can severely impair colony growth and viability, and reduce pollination ability.

Agrochemical synergism imposes higher risk to Neotropical bees than to honeybees
Hudson V. V. Tomé,Gabryele S. Ramos,Micaele F. Araújo,Weyder Cristiano Santana,Gil Rodrigues dos Santos,Raul Narciso C. Guedes,Carlos Dias Maciel,Philip L. Newland,Eugênio E. Oliveira +8 more
TL;DR: Results showed that stingless bees were more susceptible to insecticides than honeybees, and mixtures of the deltamethrin and the combined fungicide formulation induced high synergy in P. helleri, but had little effect on the mortality of A. mellifera.

TL;DR: In this paper, the authors have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations, for the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10^(12)) per year, with an average of US $33 trillion per year.
