“…The glass vial method has been used on A. mellifera, M. rotundata, and Nomia melanderi Cockerell (Halictidae) (Johansen et al, 1984), but information on feeding success was not reported. We observed that unless relative humidity was kept above 80% during the test, the droplet on the glass slide of the film canister units would evaporate very quickly, and the precise dose of solution taken by the bee could thus not be determined.…”

“…Johansen et al (1984) left bees in the feeding glass vials for three hours, but found that most bees fed within 1 hour. We observed that, with all three feeding methods, bees would usually feed within 30 minutes or not at all.…”

“…We tried to feed individual O. lignaria known amounts of sugar solution using some of the methods available from the literature (Taséi, 2002), but our success rate (percent individuals that would feed) was very low. Thus, we devised a new method, which we tested in comparison to the two most commonly used methods available (Johansen et al, 1984;van der Steen et al, 1996;Bortolotti et al, 2002;Patetta et al, 2002). All three methods were tested on two solitary bee species O. lignaria and Megachile rotundata (Fabricius) (Megachilidae), and the social bee A. mellifera.…”

A method to feed individual bees (Hymenoptera: Apiformes) known amounts of pesticides

et al. 2003

-We devised a simple method ("flower") to feed bees individually, and compared it with two other methods commonly used ("film canister" and "glass vial"). We tested the three methods on two solitary species, Osmia lignaria and Megachile rotundata, and one social species, Apis mellifera, under four different light regimes (natural, artificial, plant growth and darkness). The flower method was the most effective for all three bee species: 90-95% of the bees fed under natural light, 80-95% under artificial light, 75-100% under plant growth light, and 45-70% in darkness. Percent success was 0-50% with the film canister method, and 0-60% with the glass vial method. The flower method may allow more comprehensive future evaluation of pesticide effects on bees. oral toxicity test / individual feeding / Osmia lignaria / Apis mellifera / Megachile rotundata

“…With this method, individual bees were confined in an ice cream cup and offered the test solution in a natural flower whose reproductive column had been removed and replaced with a tiny ampoule into which the test solution was pipetted. We compared the effectiveness of the flower method with two other methods commonly used with bees not performing trophallaxis ("film canister" and "glass vial" methods; after Johansen et al, 1984;van der Steen et al, 1996;Bortolotti et al, 2002;Patetta et al, 2002) and tested the three methods on two solitary species, O. lignaria and Megachile rotundata (Fabricius) (Megachilidae), and one social species, A. mellifera (Ladurner et al, 2003). The flower method turned out to be a simple, highly effective procedure: under artificial light, the percentage of bees that consumed the test solution within 1 h (percent feeding success) ranged 380 E. Ladurner et al from 80 to 95% in all three bee species.…”

Evaluation of a standard artificial flower design to feed individual bees known amounts of pesticides

-We investigated the possibility of feeding individual bees known amounts of pesticides on a standard artificial flower with or without scent. We tested experienced and naive (without foraging experience) Osmia lignaria and Megachile rotundata females, and experienced Apis mellifera foragers, and trained (exposed to the artificial flower for 24 h) and untrained individuals of the three species. We also fed untrained individuals of all three species with feeding units made with natural flowers (Ladurner et al., Apidologie 34 (2003) 597-602). Feeding success on artificial flowers was lower (0-50%) for O. lignaria and M. rotundata, than A. mellifera (70-97%). Training improved feeding success in O. lignaria and A. mellifera, but not M. rotundata. Experience improved feeding success in O. lignaria, but not M. rotundata. Scent had no effect on feeding success for any of the three species. Feeding success with the natural flower method was high for the three species (87-90%).oral toxicity test / artificial flower / Osmia lignaria / Apis mellifera / Megachile rotundata

A laboratory feeding test was conducted on queenless micro-colonies of three bumblebee workers (Bombus terrestris L) to study the effects of low doses of imidacloprid on pollen and syrup consumption, worker survival, brood size and larval development. Two doses were used: D1 = 10 mg AI kg À1 in syrup and 6 mg AI kg À1 in pollen; D2 was 2.5 times higher in syrup and 2.7 higher in pollen. During 85 days 27, 30 and 29 micro-colonies were reared for control, D1 and D2 treatments respectively.Food consumption was not affected by either dose. During the 5-day pre-oviposition period the mean insecticide intake was 4.8 ng per day per worker in treatment D2. Both doses slightly but signi®cantly affected worker survival rate by 10% during the ®rst month, without any dose-effect relationship. Brood production was signi®cantly reduced in D1 treatment and larval ejection by workers was signi®cantly lower in D1 and D2 than in control. No signi®cant effect of D1 and D2 treatments on the duration of larval development was revealed. No residue could be detected in workers still alive after 85 days.It was concluded that the survival rate and reproductive capacity of B terrestris was not likely to be affected by prolonged ingestion of nectar produced by sun¯ower after seed-dressing treatment with imidacloprid (Gaucho), since honey or pollen collected by honeybees foraging treated sun¯ower never revealed concentrations of imidacloprid higher than 10 mg kg À1 .
