“…Ottea and Plapp (1984) also noted that both metabolic resistance and induction were associated with the production of different forms of glutathione S-transferase. Terriere and Yu (1974) suggested that higher induction in resistant fl ies was likely due to (P450) gene amplifi cation, but they rejected induction as a factor in the development of resistance in the fi eld. It was suggested that the same regulatory (trans-acting) gene may be involved in both induction and biochemical resistance (Terriere, 1983), and Plapp (1984) further proposed that a receptor involved in xenobiotic induction may be altered in resistant insects.…”

“…The same authors claimed that a nicotine concentration below 4.8 µg/mL did not cause deterrence in honeybee foraging behaviour. Due to their detoxificating enzymes, honeybees show physiological plasticity against pesticides and special floral metabolites [56,59]. However, a higher nicotine concentration (50 µg/mL) was found to cause the post-emergence mortality of the larvae [55].…”

The family Solanaceae includes several melliferous plants, which tend to produce copious amounts of nectar. Floral nectar is a chemically complex aqueous solution, dominated by sugars, but minor components such as amino acids, proteins, flavonoids and alkaloids are present as well. This study aimed at analysing the protein and alkaloid profile of the nectar in seven solanaceous species. Proteins were examined with SDS-PAGE and alkaloids were analyzed with HPLC. The investigation of protein profile revealed significant differences in nectar-protein patterns not only between different plant genera, but also between the three Nicotiana species investigated. SDS-PAGE suggested the presence of several Nectarin proteins with antimicrobial activity in Nicotiana species. The nectar of all tobacco species contained the alkaloid nicotine, N. tabacum having the highest nicotine content. The nectar of Brugmansia suaveolens, Datura stramonium, Hyoscyamus niger and Lycium barbarum contained scopolamine, the highest content of which was measured in B. suaveolens. The alkaloid concentrations in the nectars of most solanaceous species investigated can cause deterrence in honeybees, and the nectar of N. rustica and N. tabacum can be considered toxic for honeybees.

“…The bees' ability to withstand exposure to such toxicants may be a critical factor determining colony foraging performance (Smirle and Winston, 1988). Plant SC and pesticides have been shown to induce detoxifying enzymes in honeybees (Terriere and Yu, 1974).…”

The Effects of Nectar–Nicotine on Colony Fitness of Caged Honeybees

Abstract-Nectar of many bee flowers contains secondary compounds, which are considered toxic for honeybees on repeated exposure. Although many anecdotal reports indicate the toxicity of secondary compounds to bees, only a few studies have tested the extent of toxicity at different honeybee ages, especially at the larval stages. Honeybees encounter nicotine at trace concentrations (between 0.1 and 5 ppm) in floral nectar of a few Nicotiana spp. and in Tilia cordata. Adult honeybee workers tolerate these nicotine concentrations. In controlled nonchoice feeding experiments with caged bees, we investigated the effect of nicotine on hatching success and larval and forager survival. Naturally occurring concentrations of nectar-nicotine did not affect hatching success of larvae or their survival, but the latter was negatively affected by higher concentrations of nicotine (50 ppm). Concentrations of nicotine in fresh honey samples from the hives were 90% lower than the concentrations in the offered experimental sucrose solutions. Our results indicate that honeybees can cope with naturally occurring concentrations of nicotine, without notable mortality, even when consumed in large quantities for more than 3 weeks.
