1. Selectivity of registered pesticides for the corn crop on immature stages of Trichogramma pretiosum (Hymenoptera: Trichogrammatidae)
RESUMO Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) é parasitoide de ovos de lepidópteros praga no milho, Zea mays L. (Poaceae), no Brasil. Produtos químicos usados na agricultura podem ser tóxicos para este agente de controle biológico. O objetivo do presente estudo foi avaliar a longevidade, parasitismo e emergência de T. preti

2. Dispersive Liquid-Liquid Microextraction with Liquid Chromatography-Tandem Mass Spectrometry for the Determination of Triazine, Neonicotinoid, Triazole and Imidazolinone Pesticides in Mineral Water Samples
Mineral water is known for its high purity. Because mineral water is produced by the infiltration of water through the soil, there is the possibility of contamination with pesticides. The aim of this study was to develop a simple, rapid and efficient method for the extraction and preconcentration of different classes of pesticides in mineral water samples by

3. Histopathological Alterations in Common Carp (Cyprinus carpio L.) Gills Caused by Thiamethoxam
This work aimed to study the effect of new neonicotinoid thiamethoxam on the histological structure of common carp (Cyprinus carpio, L.) gills. Three experimental groups of fish were treated with 6.6, 10 and 20 mg/l thiamethoxam in laboratory conditions. Results showed different histological changes in the gill epithelium, which included lamellar lifting, ed

4. Optimization of chromatographic conditions and comparison of extraction efficiencies of four different methods for determination and quantification of pesticide content in bovine milk by UFLC-MS/MS
This paper describes the optimization of a multiresidue chromatographic analysis for the identification and quantification of 20 pesticides in bovine milk, including three carbamates, a carbamate oxime, six organophosphates, two strobilurins, a pyrethroid, an oxazolidinedione, an aryloxyphenoxypropionate acid/ester, a neonicotinoid, a dicarboximide, and thre

5. Biologia e manejo de Chalcodermus bicolor Fiedler (Col.: Curculionidae: Molytinae), em plantios de eucalipto / Biology and management of Chalcodermus bicolor Fiedler (Col.: Curculionidae: Molytinae), in eucalypt plantations
This work deals to the biology and pest management aspects of the “Eucalypt-trimmer”, a new leaf beetle in the Brazilian eucalypt plantations. Works were developed under lab conditions (Temperature = 25.29 0.20C; RH = 78.26 0.94%; photophase: scotophase = 10:14 hours). Insects were collected from cloned eucalypt in the Mucuri and Caravelas counti

6. Laboratory and field evaluation of the effects of the neonicotinoid imidacloprid on the oviposition response of Aedes (Stegomyia) aegypti Linnaeus (Diptera: Culicidae)
In this paper, we assessed the suitability of using the neonicotinoid imidacloprid with standard ovitraps by evaluating the ovicidal properties of imidacloprid and its influence on the oviposition response of gravid females of Aedes (Stegomyia) aegypti Linnaeus (Diptera: Culicidae). First, we calculated the imidacloprid lethal dose 99 (LD99) by exposing thir

7. Aptitud biológica de poblaciones de Bemisia tabaci (Gennadius) Biotipo B (Hemiptera: Aleyrodidae) con diferente susceptibilidad al insecticida thiametoxam
In two field-collected populations of de Bemisia tabaci (Gennadius) B biotype previously selected with the neonicotinoid insecticide thiamethoxam (NEO-R, NEO-N), and a population susceptible to insecticides (SUSC), the level of response to the insecticide thiametoxam, as well as the life and fertility tables were determined. At LC95, the NEO-R population sho

8. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

9. Efeitos letais e subletais de inseticidas sobre Tamarixia radiata (Waterston, 1922) (Hymenoptera:Eulophidae) / Lethal and sublethal effects of insecticides on Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae)
Tamarixia radiata (Waterston, 1922) is one of the major biological control agents of Diaphorina citri Kuwayama, vector of huanglongbing, in Brazil. This parasitoid has been very effective due to the high parasitism rates, high dispersal ability and high establishment and adaptation rates in the field. However, the efficiency of T. radiata may be affected by

10. Activity of neonicotinoid dinotefuran on Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera: Pulicidae) / Atividade do neonicotinóide dinotefuran sobre Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera: Pulicidae)
O presente trabalho teve como objetivo avaliar a atividade do neonicotinóide dinotefuran sobre Ctenocephalides felis felis. As pulgas utilizadas nos testes in vitro e nos testes controlados foram da colônia mantida no Laboratório de Desenvolvimento de Produtos Parasiticidas (LDPP) da UFRRJ, e os nos testes controlados foram utilizados cães Beagle oriundo
