Extension of the proboscis was conditioned in restrained honeybees with odor as stimulus (CS) and sucrose solution--delivered to antenna (to elicit extension proboscis) then itself--as unconditioned (US). In a first series experiments, acquisition found be very rapid, both massed spaced trials; its associative basis established by differential conditioning an explicitly unpaired control procedure (which produced marked resistance subsequent paired training); extinction spontaneous recovery...
Insects are favorable subjects for neuroethological studies. Their nervous systems relatively small and contain many individually identifiable cells. The CNS is highly compartmentalized with clear separations between multisensory higher order neuropiles in the brain serving sensory-motor routines ventral cord (Huber, 1974). rich behavior of insects includes orientation space time, visual, chemical, mechanical communication, complex motor flying, walking, swimming, nest building, defense,...
In a classical conditioning procedure, honeybees associate an odor with sucrose resulting in the capacity of to evoke appetitive response, extension proboscis (PER). Here, we study effects pairing injections octopamine (OA) as substitute for into three putative brain sites odor/sucrose convergence. OA injected mushroom body (MB) calyces or antennal lobe but not lateral protocerebral produces lasting, pairing-specific enhancement PER. During pairings, MB results additional effect, because it...
By using harmonic radar, we report the complete flight paths of displaced bees. Test bees forage at a feeder or are recruited by waggle dance indicating feeder. The flights recorded after captured when leaving hive and released an unexpected release site. A sequence behavioral routines become apparent: ( i ) initial straight in which they fly course that were on (foraging bees) learned during communication (recruited bees); ii slow search with frequent changes direction attempt to “get their...
ABSTRACT. Fixed honey‐bees were conditioned to a scent in one‐trial learning paradigm. In contrast free‐flying colour‐conditioned bees, fixed scent‐conditioned bees do not show biphasic time dependence of the response. Small metal probes used cool localized areas antennal lobes, alpha‐lobes, and calyces mushroom bodies brain at various times after conditioning. Localized cooling impaired formation memory all three structures. The susceptibility impairment conditioning lasted approximately 3...
Three neonicotinoids, imidacloprid, clothianidin and thiacloprid, agonists of the nicotinic acetylcholine receptor in central brain insects, were applied at non-lethal doses order to test their effects on honeybee navigation. A catch-and-release experimental design was which feeder trained bees caught when arriving feeder, treated with one released 1.5 hours later a remote site. The flight paths individual tracked harmonic radar. initial phase controlled by recently acquired navigation...
Glyphosate (GLY) is a herbicide that widely used in agriculture for weed control. Although reports about the impact of GLY snails, crustaceans and amphibians exist, few studies have investigated its sublethal effects non-target organisms such as honeybee Apis mellifera, main pollen vector commercial crops. Here, we tested whether exposure to three concentrations (2.5, 5 10 mg l(-1): corresponding 0.125, 0.250 0.500 μg per animal) affects homeward flight path honeybees an open field. We...
The decline of pollinators worldwide is growing concern and has been related to the use plant-protecting chemicals. Most studies have focused on three neonicotinoid insecticides (clothianidin, imidacloprid, thiamethoxam) currently subject a moratorium in EU. Here, we focus thiacloprid, widely used cyano-substituted thought be less toxic honey bees which increased last years. Honey (Apis mellifera carnica) were exposed chronically thiacloprid field for several weeks at sublethal...
