Effects of imidacloprid and deltamethrin on associative learning in honeybees under semi-field and laboratory conditions.
We have compared the sublethal effects of two insecticides in the honeybee (imidacloprid and deltamethrin) in both semi-field and laboratory conditions. A sugar solution containing 24 microg kg(-1)Expand

Learning performances of honeybees (Apis mellifera L) are differentially affected by imidacloprid according to the season.
To establish the sublethal concentrations domain, acute and chronic oral tests were conducted on caged honeybee workers (Apis mellifera L) using imidacloprid and a metabolite, 5-OH-imidacloprid,Expand

Imidacloprid impairs memory and brain metabolism in the honeybee (Apis mellifera L.)
Imidacloprid is a chloronicotinyl insecticide which interacts with insect nicotinic acetylcholine receptors. Thirty minutes after oral treatment of honeybees with imidacloprid, the olfactory learningExpand

Effects of Cry1Ab protoxin, deltamethrin and imidacloprid on the foraging activity and the learning performances of the honeybee Apis mellifera, a comparative approach
Parmi les strategies de protection des cultures, l'usage d'insecticides de synthese constitue la pratique la plus courante, mais les methodes alternatives comme les plantes transgeniques sont de plusExpand

Effects of artificial diet containing GNA and GNA-expressing potatoes on the development of the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Aphidiidae).
Aphid parasitoids are important biological control agents. The possibility arises that whilst foraging on insect-resistant transgenic plants, they are themselves at risk from direct and indirectExpand

Long‐term effects of soybean protease inhibitors on digestive enzymes, survival and learning abilities of honeybees
We have investigated the effects of long‐term ingestion of two serine proteinase inhibitors (PIs), the Kunitz Soybean trypsin inhibitor (SBTI) and the Bowman‐Birk inhibitor (BBI) on survival,Expand

Direct and indirect sublethal effects of Galanthus nivalis agglutinin (GNA) on the development of a potato-aphid parasitoid, Aphelinus abdominalis (Hymenoptera: Aphelinidae).
Snowdrop lectin (Galanthus nivalis agglutinin, GNA), has been shown to confer partial resistance to two potato aphids Myzus persicae and Aulacorthum solani, when incorporated in artificial dietExpand

Behavioural methods to assess the effects of pesticides on honey bees.
We reported on the use of experimental procedures dealing with these behavioural skills in the assessment of pesticide effects. The relevance of the following methods are discussed: (1) use ofExpand

Effects of Proteinase Inhibitor Ingestion on Survival, Learning Abilities and Digestive Proteinases of the Honeybee
The impact on beneficial insects of proteinase inhibitors expressed in pest-resistant transgenic crops needs to be assessed before the release of these plants into the environment. Three proteinaseExpand
