“…Honey bees can become exposed to neonicotinoids directly in the field at the time of application as well as during consumption of pollen and nectar from treated plants. 3 Cotton, an important cash crop is susceptible to many insect pests. In order to control the losses due to these insect pests, pesticide use on cotton crop is common.…”

BACKGROUND: Exposure of Apis mellifera to neonicotinoid insecticides is one of the factors attributed to the recent decline in A. mellifera populations resulting in economic and ecological losses due to loss of pollination services. Honey bees can get exposed to neonicotinoids like imidacloprid directly in the field at the time of application as well as during consumption of pollen and nectar from treated plants. So, the fate of imidacloprid in commodities to which honey bees get exposed needs to be overhauled. RESULTS: Residue of imidacloprid was investigated following imidacloprid application as seed treatment (2.4 and 4.8 g a.i. kg -1 seed) at the time of sowing and as foliar spray (17.8 and 35.6 g a.i. ha -1 ) at 70 days after sowing when the crop was at full bloom stage. The imidacloprid residue was below limit of quantification (LOQ) in flowers, necatariferous tissue, pollen from seed-treated cotton plants and honey collected from hives kept in plots with seed-treated cotton plants. However, average initial imidacloprid residue (2 h after spray) was 1.84 and 1.95 mg kg −1 in flowers; 0.22 and 0.24 mg kg −1 in nectariferous tissue; 0.88 and 0.96 mg kg −1 in pollen collected from plants sprayed with imidacloprid @ 17.8 g a.i. ha −1 at locations Faridkot and Bathinda, respectively. The average initial imidacloprid residue (21 days after spray) in honey collected from hives was 0.01 mg kg −1 . CONCLUSION: The residue in different substrates sampled from seed treated cotton plants was below LOQ. However, its foliar spray at bloom time resulted in imidacloprid residue in flower, nectariferous tissue, pollen and honey sampled from hives placed in plots.

“…buniifolium on survival and food consumption was evaluated. EOEb was applied in the diet to ensure that the putative sub-lethal effects could be observed, since the toxicity of xenobiotics in honeybees is usually greater by oral intake [ 54 ]. Moreover, direct feeding with sanitary products provides a more direct and systemic approach for the exposure of the etiological agents of various honeybee pathologies, and circumvents issues related to variable fumigant volatility [ 52 ].…”

Sub-lethal effects of the consumption of Eupatorium buniifolium essential oil in honeybees

et al. 2020

When developing new products to be used in honeybee colonies, further than acute toxicity, it is imperative to perform an assessment of risks, including various sublethal effects. The long-term sublethal effects of xenobiotics on honeybees, more specifically of acaricides used in honeybee hives, have been scarcely studied, particularly so in the case of essential oils and their components. In this work, chronic effects of the ingestion of Eupatorium buniifolium (Asteraceae) essential oil were studied on nurse honeybees using laboratory assays. Survival, food consumption, and the effect on the composition of cuticular hydrocarbons (CHC) were assessed. CHC were chosen due to their key role as pheromones involved in honeybee social recognition. While food consumption and survival were not affected by the consumption of the essential oil, CHC amounts and profiles showed dose-dependent changes. All groups of CHC (linear and branched alkanes, alkenes and alkadienes) were altered when honeybees were fed with the highest essential oil dose tested (6000 ppm). The compounds that significantly varied include n-docosane, n-tricosane, n-tetracosane, n-triacontane, n-tritriacontane, 9-tricosene, 7-pentacosene, 9-pentacosene, 9-heptacosene, tritriacontene, pentacosadiene, hentriacontadiene, tritriacontadiene and all methyl alkanes. All of them but pentacosadiene were up-regulated. On the other hand, CHC profiles were similar in healthy and Nosema -infected honeybees when diets included the essential oil at 300 and 3000 ppm. Our results show that the ingestion of an essential oil can impact CHC and that the effect is dose-dependent. Changes in CHC could affect the signaling process mediated by these pheromonal compounds. To our knowledge this is the first report of changes in honeybee cuticular hydrocarbons as a result of essential oil ingestion.

“…Grooming behavior has traditionally been evaluated by marking and tracking bees in observation hives or petri dishes. Only two studies investigated the influence of pesticides on allo-grooming; both reported a lack of effect after exposure to imidacloprid, bioinsecticides (essential oil and geraniol; Santos et al, 2018), thiacloprid and tau-fluvalinate (Retschnig et al, 2015). Conversely, self-grooming performance appeared more sensitive to intoxication.…”

“…While de Mattos et al (2017) found a reduction in the duration of self-grooming after exposure to acaricides (coumaphos, amitraz and tau-fluvalinate), bees intoxicated with pesticides, such as neonicotinoids (imidacloprid, thiamethoxam, clothianidin, dinotefuran) (Williamson et al, 2014), acetylcholinesterase inhibitors (Williamson et al, 2013), permethrin (Cox and Wilson, 1984) and oxalic acid , showed an increased propensity to perform self-grooming. However, two toxicological studies found no effect of pyrethroids (including tau-fluvalinate and permethrin) (Oliver et al, 2015), imidacloprid or bioinsecticides on self-grooming (Santos et al, 2018).…”
