1. SYNTHESIS OF GLYCEROL-FLUORINATED TRIAZOLE DERIVATIVES AND EVALUATION OF THEIR FUNGICIDAL ACTIVITY
The control of fungal species in agriculture is mainly conducted with the use of contact or systemic fungicides. However, environmental and human health concerns and increased resistance of fungal species to existing fungicides have increased the pressure on researchers to find new active ingredients for fungal control which present low toxicity to non-targe

2. Efficacy of Trichogrammatidae Species (Hymenoptera) Submitted to the Herbicide Glyphosate
RESUMO: Informações sobre herbicidas seletivos, incluindo o glyphosate, que não afetam organismos não alvo, como inimigos naturais, são importantes nos programas de manejo integrado de pragas na cultura do milho. O glyphosate, na dose de 13,94 L ha-1, foi avaliado em fêmeas de 10 espécies de Trichogrammatidae (Hymenoptera). Uma fêmea de cada espécie

3. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

4. INSECTICIDAL ACTIVITY OF DIENAMIDES ON CABBAGE CATERPILLAR AND BENEFICIAL INSECTS
The demand for new insecticides is increasing due to the appearance of insect populations that are resistant to currently used products. New insecticides should be efficient in controlling pests and present low toxicity to non-target organisms. Ascia monuste (Lepidoptera: Pieridae) is a destructive pest of cole vegetables, and the fire ant Solenopsis saeviss

5. Assessment of the Toxicity of Sub-chronic Low and High Doses of the Bio-insecticide Spinosad on the Liver, Kidney and the Cerebellum in Male Albino Mice
ABSTRACT Spinosad (SPD) is a highly selective insect control product. However, it was reported that SPD has toxicity toward other non-target organisms. This study was conducted to address the toxic effect of two sub-chronic low and high doses; 35 and 350 mg/kg SPD on some biochemical, histological and immunohistochemical parameters of the liver, kidney and c

6. Antiviral activity of animal venom peptides and related compounds
Abstract Viruses exhibit rapid mutational capacity to trick and infect host cells, sometimes assisted through virus-coded peptides that counteract host cellular immune defense. Although a large number of compounds have been identified as inhibiting various viral infections and disease progression, it is urgent to achieve the discovery of more effective agent

7. Synthesis and Insecticidal Activity of Lactones Derived from Furan-2(5H)-one
Ten 4,7-methanoisobenzofuran-1(3H)-ones were synthesized and their insecticidal activities against the insect pest Diaphania hyalinata were evaluated. The most active substances have been selected from the initial screening to find the dose to kill 50 (LD50) and 90% (LD90) of the melonworm. Time-mortality curves of the three selected formulations at the LD90

8. Modelagem computacional do efeito bystander das radiações ionizantes via autômato celular e técnica Monte Carlo
Until the 1990s it was believed that the DNA was the only target molecule of ionizing radiation. But some observations have questioned this theory. In 1992, the bystander effect was described by Nagasawa and Little. This effect is responsible for a series of answers as death, chromosomal instability or other abnormalities that occur in non-irradiated cells,

9. Effects of genetically modified cotton (Bollgard®) on non-target organisms / Efeitos do algodoeiro geneticamente modificado (Bollgard®) em organismos não-alvo
The effects of the genetically modified cotton (Bollgard®) expressing Bacillus thuringiensis (Bt) Cry1Ac toxin on non-target arthropods was evaluated under laboratory and field studies. Evaluations of arthropod abundance on Bollgard® cotton (Delta Pine 90) and on its isoline (Acala 90) were carried out during three consecutive field seasons. The first stud

10. PARÂMETROS DE ESTRESSE OXIDATIVO E ESTUDO DE LESÕS HISTOPATOLÓGICAS EM JUNDIÁS (Rhamdia quelen) EXPOSTOS A AGROQUÍMICOS
Due to the proximity of crop and fish culture areas, some agrichemicals that could be harmful for fish could enter into fishponds by different ways, such as by leaching through rain. The contamination of the aquatic environment by pesticides is a problem of global importance because of its toxic effects on non-target organisms. These products may affect toxi

11. Segurança alimentar e governança para transgenicos : um estudo sobre o ativismo transnacional / Food safety and governance : a study on transnational activism
Global governance can be described as a series of arrangements among actors of the international system, which take on the form of a "web" of control mechanisms. It verifies that an objective of large non-government organizations is to influence international politics through the implementation of actions in this plan. However, access to the most effective s

12. OXIDATIVE STRESS BIOMARKERS IN CARP (Cyprinus carpio) EXPOSED TO CARBOFURAN AND FIPRONIL INSECTICIDES IN RICE FIELD CONDITIONS / BIOMARCADORES DE ESTRESSE OXIDATIVO EM CARPAS (Cyprinus carpio) EXPOSTAS AOS INSETICIDAS CARBOFURAN E FIPRONIL EM CONDIÇÕES DE LAVOURA DE ARROZ
The contamination of the aquatic environment by pesticides is a problem of global importance because of their toxic effect on non-target organisms. These products may affect toxicological parameters and oxidative stress in fish. The carp is cultivated in southern of Brazil and has great comercial interest. There are few studies in our country regarding the u
