“…The use of these insecticides in bee-attracting flowering crops is growing worldwide (Köhler and Triebskorn 2013), and the fact that their neurotoxic activity may affect pollinators justifies the increasing number of studies that seek to fill these gaps in knowledge (Gill et al 2012;Arena and Sgolastra 2014;Costa et al 2014;Fairbrother et al 2014;Feltham et al 2014). Neonicotinoids can be sprayed, applied to the soil or applied as a seed coating (Blacquiere et al 2012).…”

“…Most studies on the effects of pesticides on bees have evaluated the adult stage (Moraes et al 2000), mainly using the species Apis mellifera as a study model (Cresswell 2011;Costa et al 2014;Fairbrother et al 2014). Studies on the exposure of bees during the larval stage through in vitro rearing tests also focus on this species (Aupinel et al 2007;Hendriksma et al 2011;Wilkins et al 2013;Tavares et al 2015).…”

-In Brazil, where the use of neonicotinoids is allowed in bee-attracting flowering crops, we investigated whether thiamethoxam intake during the larval stage of the native bee species Scaptotrigona aff. depilis affects the survival and development by exposing larvae to contaminated food. Our results indicated that the larvae exposed to the dose at a field-realistic level and to the doses ranging around it had their survival rates significantly impaired. At the highest doses, we observed larvae and pupae with shorter and longer development times, respectively, and the formation of smaller and asymmetric specimens. Evidently, we need to consider that thiamethoxam reaches the pollen and nectar at residual levels, and that they are processed by nurse bees before destined for offspring. Nevertheless, our findings suggest a warning, since the individuals had their biological parameters affected by thiamethoxam, when exposed to doses at field-realistic levels.larval food / in vitro rearing / adverse effects / developmental stage / insecticides

“…toxicity to A. mellifera and T. hyalinata. Chemical and biological control of pests require selective products for integrated pest management programs and insecticides should not impact pollinator insects, which are indispensable for the propagation of many cultivated and native plants 2,10,11 . The botanical product toxicity to insects such as natural enemies and pollinators should be evaluated due to the demand for organic food 29,30 .…”

the toxicity of essential oils that can be used in insect pest management to pollinators needs further studies. Apis mellifera Linnaeus and Trigona hyalinata (Lepeletier) (Hymenoptera: Apidae) foragers were exposed by three pathways to ginger, mint, oregano and thyme essential oils to provide their Lc 50, LD 50 and Lc 90, LD 90 . oregano and thyme were more toxic through contact and topically for A. mellifera while the toxicity of mint and ginger was lower. Trigona hyalinata was more tolerant to the essential oils than A. mellifera. in the walking test, the area was treated (totally or partially) with sub-doses (Lc 50 ) obtained via contact. the area fully treated with oregano reduced the distance traveled and the movement speed increased the number of stops by A. mellifera. Similar results were observed for T. hyalinata with oregano and thyme oils. Apis mellifera showed irritability remaining shorter time in the area partially treated with ginger, mint and thyme essential oils while T. hyalinata had similar behavior with ginger and thyme. essential oils did not repel A. mellifera or T. hyalinata, but those of ginger, mint and thyme reduced the time spent by A. mellifera in areas treated with sublethal doses. oregano and thyme essential oils reduced the survival, mainly, of A. mellifera, while ginger and mint were selective for both pollinators.Bees are essential for plant propagation 1 , but factors such as pathogens, habitat losses and intensive pesticide use are reducing their populations 2 . The decline of bee colonies, known as Colony Collapse Disorder (CCD), threatens pollination and the production of honey, propolis, royal jelly, and wax 3,4 . Bees are exposed to insecticides during the pollen and nectar harvesting through contact with the treated plant surface and the ingestion of sap from seeds coated with systemic insecticides 5,6 abamectin, acetamiprid, cartap-hydrochloride, chlorfenapyr, deltamethrin and thiamethoxam were toxic to Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae) workers by direct spraying; diet treated and contact with pulverized leaves 2 . Larvae mortality was high and adult mobility of Melipona quadrifasciata Lepeletier, 1836 (Hymenoptera: Apidae) low with diet treated with imidacloprid 7 . These insecticides act on arthropods, causing physiological and behavioral effects by directly interfering in the acetylcholine receptors 7 . In addition, insecticides may affect learning, foraging, growth, besides pupa malformation, adult emergence and reproduction 8,9 and caused irritability and repelled bees 7 . Residues in wax, nectar and pollen reduce the quality and value of these products 4 .The vulnerability of A. mellifera to pesticides has been studied 2,10 but the effect of these products on native stingless bees such as Trigona hyalinata (Lepeletier) (Hymenoptera: Apidae) is little understood. The development period of stingless bees is generally longer than that of Apis spp., and, therefore, their survival is more under

ResumoA legislação ambiental brasileira, subsidiada pela Instrução Normativa nº 02/2008 do Ministério da Agricultura, Pecuária e Abastecimento, obriga que as empresas operadoras aeroagrícolas realizem o tratamento dos efluentes gerados após a lavagem das aeronaves. Para este fim, é sugerido pela legislação o uso de um sistema de degradação baseado na ozonização. Avaliou-se a eficiência do sistema recomendado pela legislação em promover a degradação do princípio ativo flufenoxuron (inseticida Cascade® 100), onde foram analisadas a concentração e a quantidade em massa da molécula em todas as etapas do sistema. Foram avaliados dois tratamentos distintos, usando 1,0 e 2,0 g de ozônio/hora, em um sistema industrial de geração de ozônio, usando três períodos de ozonização diferentes (1, 3 e 6 horas), em temperatura ambiente e pH em torno de 6,0. Constatou-se que, em cada lavagem, é gerado um volume médio de 132 L de efluente (112 L de água mais 20 L de calda residual). Após sofrer os tratamentos com 1,0 e 2,0 g de O 3 /hora foram obtidos, respectivamente, os seguintes resultados: diminuição da concentração de flufenoxuron no efluente (-82,8 e -86,0%) e decréscimo na massa de flufenoxuron (-44,8 e -63,2%). O sistema mostrou-se eficiente no tratamento do efluente contendo resíduos do inseticida Cascade® 100.Palavras-chave: ozônio, oxidação, pátio de descontaminação. TREATMENT OF EFFLUENT CONTAINING FLUFENOXURON GENERATED BY WASHING AND DISPOSAL OF AERIAL APPLICATIONS AbstractThe Brazilian environmental legislation, subsidized by Normative Instruction No. 02/2008 of the Ministry of Agriculture, Livestock and Food Supply, obliges the aeroagriculture operators to treat the effluents generated after washing the aircraft. To this end, the use of a degradation system based on ozonation is suggested by legislation. The efficiency of the system recommended by the legislation in promoting the degradation of the active principle flufenoxuron (Cascade® 100 insecticide) was evaluated through the analysis of pesticide concentration and the mass quantity in all the system stages. Two different treatments were evaluated using 1.0 and 2.0 g ozone/hour. It was found that an average volume of 132 L of effluent (112 L of water plus 20 L of residual pesticide formulation) is generated for each wash. After treatment with 1.0 and 2.0 g O 3 /hour respectively, the following results were obtained: reduction of the flufenoxuron concentration in the effluent (-82.8 and -86.0%); decrease on the amount of flufenoxuron (-44.8 and -63.2%). The system proved to be efficient in the treatment of effluent containing flufenoxuron residues.
