TLDR
Flowers with real adult beetles had as much nectar as those without, so there was no evidence that the avoidance of simulated beetle deterred nectar-foraging bees from landing.Abstract:
SUMMARYAdults and larvae of the pollen beetle Meligethes aeneus (Nitidulidae) are abundant in flowers of oilseed rape (Brassica napus) in the UK. Their effects on the foraging behaviour of honey bees (Apis mellifera) were investigated in the field. Bees foraged predominantly from fully open flowers, but landed on fully open flowers containing adult beetles less often than would be expected from the proportion of flowers with beetles in them. Of 107 flowers visited by bees, 99 had no adult beetles, whereas of 100 flowers selected at random, 81 had no beetles; the difference was significant. Simulated adult beetles (black spots on the petals) deterred nectar-foraging bees from landing. Bees given a choice between flowers with four black or four clear spots and one black or one clear spot were 2.5 times and 2.4 times, respectively, more likely to visit flowers with clear spots. Flowers with real adult beetles had as much nectar as those without, so there was no evidence that the avoidance of simulated beetle...read more

Honey-bee-mediated infection of pollen beetle (Meligethes aeneus Fab.) by the insect-pathogenic fungus, Metarhizium anisopliae
TL;DR: In both winter- and spring-sown rape experiments, a greater mortality of pollen beetles occurred in treated plots than in control plots, and there was no evidence of any adverse effect on the honey-bee colonies.

TL;DR: In field tests with six species of flowering hosts, far more landings occurred on flowers than on foliage for all plants except Hibiscus syriacus which bears flowers along the main stem rather than terminally, and trials with elevated plants showed that height of the floral display contributes to beetles’ landing on flowers.
Journal ArticleDOI
Factors affecting floral herbivory in a limestone grassland
TL;DR: The amount of petal damage appeared to result from the prevalence of large-flowered species early and late in the season rather than from a preference for flower size and petal thickness per se, and the evolutionary significance of floral herbivory is discussed.
