ABSTRACT The death of honey bees, Apis mellifera L., and the consequent colony collapse disorder causes major losses in agriculture and plant pollination worldwide. The phenomenon showed increasing rates in the past years, although its causes are still awaiting a clear answer. Although neonicotinoid systemic insecticides used for seed coating of agricultural crops were suspected as possible reason, studies so far have not shown the existence of unquestionable sources capable of delivering… Expand
Rapid analysis of neonicotinoid insecticides in guttation drops of corn seedlings obtained from coated seeds.
TLDR
Current results confirm that the physiological fluids of the corn plant can effectively transfer neonicotinoid insecticides from the seed onto the surface of the leaves, where guttation drops may expose bees and other insects to elevated doses of neurotoxic insecticides. Expand
Methiocarb metabolites are systemically distributed throughout corn plants grown from coated seeds
Systemic insecticides such as neonicotinoids are widely used in seed coating practices for pest control in many crops, e.g., corn. Their success is due to their ability to protect the whole plant,Expand
Tracking neonicotinoids following their use as cotton seed treatments
TLDR
Neonicotinoid concentration data from cotton leaves appears to be consistent with the claim that seed treatments protect plants for 3–4 weeks; by 30 days post-planting, neonicotinoids concentrations fell, in general, to 200 ng/g or lower. Expand
Neonicotinoids, bee disorders and the sustainability of pollinator services
TLDR
The limited available data suggest that neonicotinoids are likely to exhibit similar toxicity to virtually all other wild insect pollinators, therefore a transition to pollinator-friendly alternatives to neonicotine is urgently needed for the sake of the sustainability of pollinator ecosystem services. Expand
Neonicotinoid seed treatment products – Occurrence and relevance of guttation for honeybee colonies
TLDR
It can be concluded that exposure of honeybee colonies to guttation fluid, excreted from neonicotinoid seed-treated crop plants, did not pose an unacceptable acute or chronic risk to honeybee colony development or survival, and does not adversely interfere with bee keeping practices. Expand
Lethal aerial powdering of honey bees with neonicotinoids from fragments of maize seed coat.
Losses of bees have been reported in Italy concurrent with the sowing of maize coated with neonicotinoids where pneumatic drill- ing machine were used. Solid particles with systemic insecticide,Expand
Neonicotinoids from coated seeds toxic for honeydew-feeding biological control agents.
TLDR
Biochemical analyses demonstrated that honeydew excreted by the soybean aphid contained substantial concentrations of neonicotinoids even one month after sowing of the crop, which has important environmental and economic implications because Honeydew is the main carbohydrate source for many beneficial insects in agricultural landscapes. Expand
Residues of Neonicotinoid Insecticides in Bee Collected Plant Materials from Oilseed Rape Crops and their Effect on Bee Colonies
TLDR
No negative effects of neonicotinoids on the bee mortality, brood development, strength, and honey yield of healthy bee colonies were found throughout the study period, however, the risk exposure of bee colonies on adverse impact of pesticide residues is high in areas of intensively cultivated oilseed rape. Expand
Uptake of Neonicotinoid Insecticides by Water-Foraging Honey Bees (Hymenoptera: Apidae) Through Guttation Fluid of Winter Oilseed Rape
TLDR
The amounts of thiamethoxam found in the honey sacs of water-foraging honey bees were therefore below the thresholds in nectar and pollen that are considered to have negative effects on honey bees after chronic exposure. Expand
Mowing mitigates bioactivity of neonicotinoid insecticides in nectar of flowering lawn weeds and turfgrass guttation.
TLDR
The hazard to nontarget insects via nectar of flowering weeds in treated lawns can be mitigated by adhering to label precautions and mowing to remove blooms if they are inadvertently sprayed. Expand

Presence of the a.i. imidacloprid on vegetation near corn fields sown with Gaucho ® dressed seeds
TLDR
The investigation showed that Gaucho ® dressed corn seeds during sowing operations can release imidacloprid into the environment, and therefore bees and wild pollinator insects could bee exposed to the insecticide molecule. Expand
Safety of imidacloprid seed dressings to honey bees: a comprehensive overview and compilation of the current state of knowledge
This paper reviews the available data on the risk potential posed by imidacloprid seed dressings to honey bees. Key studies are briefly described and their results are discussed; of particularExpand
Applied aspects of neonicotinoid uses in crop protection.
TLDR
New formulations have been developed to optimize the bioavailability of neonicotinoids through improved rain fastness, better retention and spreading of the spray deposit on the leaf surface, combined with higher leaf penetration, which will turn neonic nicotine into the most important chemical class in crop protection within the next few years. Expand
Abnormal Foraging Behavior Induced by Sublethal Dosage of Imidacloprid in the Honey Bee (Hymenoptera: Apidae)
TLDR
It is demonstrated that sublethal dosages of imidacloprid were able to affect foraging behavior of honey bees and showed abnormalities in revisiting the feeding site. Expand
Efficacy of Neonicotinoid Seed Treatments to Reduce Soybean Aphid Populations Under Field and Controlled Conditions in Nebraska
TLDR
Leaf specific bioassays and leaf specific imidacloprid and thiamethoxam quantification indicated that thiamETHoxam was present in the plant at higher concentrations and for a longer period than previously thought, indicating the season-long efficacy of neonicotinoid insecticide seed treatments to control soybean aphid. Expand
Chemistry and biology of thiamethoxam: a second generation neonicotinoid.
TLDR
Low use rates, flexible application methods, excellent efficacy, long-lasting residual activity and favourable safety profile make this new insecticide well-suited for modern integrated pest management programmes in many cropping systems. Expand
Peramine and other fungal alkaloids are exuded in the guttation fluid of endophyte-infected grasses.
TLDR
This is the first report showing the mobilization of fungal alkaloids into plant fluids by the host plant in grass-endophyte associations, and a highly sensitive method for the analysis of peramine is developed. Expand
Risk of environmental contamination by the active ingredient imidacloprid used for corn seed dressing. Preliminary results
Aim of the study was to detect the possible loss of a.i. imidacloprid through the fan drain of pneumatic seed drills during corn sowing operations. The experiment regarded Gaucho ® dressed cornExpand
Characteristics of imidacloprid toxicity in two Apis mellifera subspecies
TLDR
Imidacloprid ranks among the more potent contact insecticides in this important pollinator species, and response kinetics showed that mortality was delayed at the higher doses of imidaclobrid. Expand
Study on laminar hydathodes of Ficus formosana (moraceae) III. Salt injury of guttation on hydathodes
TLDR
The results imply that epithem possesses some special mechanisms that have been evolved to adapt the damage stress and some morphological changes such as the sinuous cell wall, proliferation of peroxisomes and the abundant endomembrane systems, and the conspicuous fluid-phase endocytosis are suggested.
