“…One can also argue that these colonies had not been culled year after year by repeated action of toxicants. All these factors could explain why the imidacloprid absorbed did not entail any lethal effect. The local bee race used in the present study may be less sensitive to imidacloprid than local races that prevail in the areas where bee keepers observed the problems that they relate to the use of this insecticide.It has been known for many years that honey bee colonies vary widely in their ability to withstand insecticide exposures 48, 49. Moreover, compared with other insecticides, the acute toxicity of imidacloprid varies greatly in the honey bee: by oral route, LD 50 ranges from 5.4 ng per bee10 to 40.9 ng per bee,17 by contact the range is from 6.7 to 230.3 ng per bee.…”

Two groups of eight honey bee colonies were fed with two different concentrations of imidacloprid in saccharose syrup during summer (each colony was given 1 litre of saccharose syrup containing 0.5 microg litre(-1) or 5 microg litre(-1) of imidacloprid on 13 occasions). Their development and survival were followed in parallel with control hives (unfed or fed with saccharose syrup) until the end of the following winter. The parameters followed were: adult bee activity (number of bee entering the hive and pollen carrying activity), adult bee population level, capped brood area, frequency of parasitic and other diseases, mortality, number of frames with brood after wintering and a global score of colonies after wintering. The only parameters linked to feeding with imidacloprid-supplemented saccharose syrup when compared with feeding with non-supplemented syrup were: a statistically non-significant higher activity index of adult bees, a significantly higher frequency of pollen carrying during the feeding period and a larger number of capped brood cells. When imidacloprid was no longer applied, activity and pollen carrying were re-established at a similar level for all groups. Repeated feeding with syrup supplemented with imidacloprid did not provoke any immediate or any delayed mortality before, during or following the next winter, whereas such severe effects are described by several French bee keepers as a consequence of imidacloprid use for seed dressing in neighbouring cultures. In any case, during the whole study, mortality was very low in all groups, with no difference between imidacloprid-fed and control colonies. Further research should now address several hypotheses: the troubles described by bee keepers have causes other than imidacloprid; if such troubles are really due to this insecticide, they may only be observed either when bees consume contaminated pollen, when no other sources of food are available, in the presence of synergic factors (that still need to be identified), with some particular races of bees or when colonies are not strong and healthy.

Abstract. Laboratory dose-response studies were conducted with four species of adult bees, Apis mellifera (workers), Andrena erythronii (females), Megachile rotundata (females), and Bombus terricola (workers), using six insecticides, permethrin, mexacarbate, aminocarb, fenitrothion, carbaryl, and trichlorfon. All insecticides were applied topically to the thorax of the bees as technical grade in an acetone carrier. Mortality was accumulated over 48 h, and probit analyses were conducted separately on data sets expressed in units of IxgAI (active ingredient)/g body weight and of p~gAI/bee. LDso values with 95% confidence limits and slopes with standard errors are provided for each bee/insecticide combination in each data set. Relative toxicities, relative susceptibilities, and fresh body weights are also provided. The analysis in units of p~gAI/g body weight indicated that the insecticides were typically ranked in order of decreasing toxicity--permethrin, mexacarbate, aminocarb, fenitrothion, carbaryl, and trichlorfon. Likewise, the bees ranked from the most to least susceptible in the order ofA. mellifera, A. erythronii, M. rotundata, andB. terricola. Trends within the data set for units of IxgAl/bee were less consistent. These data are discussed and compared with other published data on the toxicology of insecticides to bees and from the perspective of risk assessment.

“…One would thus expect that bees from different patrilines differ in their pesticide sensitivity or detoxification capacities, but this remains to be investigated. However, several studies indicate that the genetic background might influence the response to pesticides, given that the toxicity of a chemical varies between bees originating from different subspecies (Ladas 1972;Suchail et al 2000;Laurino et al 2013;Sandrock et al 2014;Rinkevich et al 2015) or colonies from the same strain (Tahori et al 1969;Smirle and Winston 1987). Indeed, one CYP450 gene was found to vary in expression between colonies originating from a hybrid population (A. m. mellifera /carnica ) (Derecka et al 2013).…”

“…Within honeybee colonies, differences in body size between workers are very minor, but nurses are heavier than foragers and a large variability in body weight is observed between nurse bees as compared to foragers (Vance et al 2009). Accordingly, it was found that heavier bees are less sensitive to toxicants than lighter bees (Tahori et al 1969;Gerig 1975;Nogueira-Couto et al 1996).…”

-Honeybee exposure to pesticides is widely accepted, but the role they play in impacting bee health remains controversial. The development of risk assessment procedures is notably a difficult task due to the variability of responses observed for a single pesticide at a specific dose. Indeed, honeybees, during most of their lifetime, are exposed to fluctuating environmental conditions (e.g., pathogen pressure, resource availability, climatic conditions) and can go through important physiological changes within a few days (e.g., behavioral maturation) or even a day (e.g., circadian clock), which are all factors that can affect the bee response to pesticides. Integrating the range of variability in conditions experienced by bees is relevant to honeybee toxicology and will contribute to a better assessment of their susceptibility to pesticides. The aim of this review is therefore to provide empirical evidence of how co-exposure to stressors, and environmental and endogenous factors modulate the honeybee response to pesticide.Apis mellifera / pesticide toxicity / ecotoxicology / toxicodynamics / toxicokinetics / co-exposure / risk assessment
