1. HEAT-APPLICATOR MACHINE FOR WEED CONTROL
ABSTRACT Pesticide environmental risks and increased weed resistance have encouraged studies for alternatives to herbicides. Among these are weed thermal control methods by controlled heat application machines. Thus, this study aimed to test a prototype of heat-applicator machine as a function of changes in gas pressure, travel speed, and tire traffic effect

3. Resistance to temephos and deltamethrin in Aedes aegypti from Brazil between 1985 and 2017
BACKGROUND Aedes aegypti populations in Brazil have been subjected to insecticide selection pressures with variable levels and sources since 1967. Therefore, the Brazilian Ministry of Health (MoH) coordinated the activities of an Ae. aegypti insecticide resistance monitoring network (MoReNAa) from 1999 to 2012. OBJECTIVES The objective of this study was t

4. Estimation of Aedes aegypti (Diptera: Culicidae) population size and adult male survival in an urban area in Panama
Traditional mosquito control strategies rely heavily on the use of chemical insecticides. However, concerns about the efficiency of traditional control methods, environmental impact and emerging pesticide resistance have highlighted the necessity for developing innovative tools for mosquito control. Some novel strategies, including release of insects carryin

5. Searching for convergent evolution in manganese superoxidase dismutase using hydrophobic cluster analysis
There are numerous examples of convergent evolution in nature. Major ecological adaptations such as flight, loss of limbs in vertebrates, pesticide resistance, adaptation to a parasitic way of life, etc., have all evolved more than once, as seen by their analogous functions in separate taxa. But what about protein evolution? Does the environment have a stron

6. Evolution of insecticide resistance in non-target black flies (Diptera: Simuliidae) from Argentina
Black flies, a non-target species of the insecticides used in fruit production, represent a severe medical and veterinary problem. Large increases in the level of resistance to the pyrethroids fenvalerate (more than 355-fold) and deltamethrin (162-fold) and a small increase in resistance to the organophosphate azinphos methyl (2-fold) were observed between 1

8. Controle do caruncho-do-feijoeiro Zabrotes subfasciatus com óleos vegetais, munha, materiais inertes e malathion.
Na busca de alternativas ao controle químico do caruncho Zabrotes subfasciatus (Coleoptera:Bruchidae), avaliou-se, em feijoeiro (Phaseolus vulgaris L.), o efeito de três genótipos, cv. Carioca e duas linhagens contendo a proteína arcelina (Arc1 e Arc3), e da adição nos grãos armazenados de óleo de soja (Glycine max Merrill); óleo de nim (Azadirachta

10. LixiviaÃÃo, formaÃÃo de resÃduos ligados e biorremediaÃÃo de atrazina em solo subtropical submetido à aplicaÃÃo de Ãgua residuÃria da suinocultura / Leaching, bound residues formation and bioremediation of the atrazine in subtropical soil submitted of swine wastewater application
Atrazine is a triazine herbicide, widely used in agriculture to control weeds in corn and cane sugar farming. However, atrazine is considered a pesticide moderately persistent in the environment and the application of wastewater to the soil can affect its environmental performance. In this study, the effects of wastewater from swine (ARS) in leaching, dissip

11. Estudo da remoção e toxicidade dos pesticidas atrazina e oxifluorfem pela cianobactéria "Microcystis novacekii" em condições de cultivo.
Water contamination by pesticides due to anthropogenic activities has become a global concern in terms of environmental damage and public health. The cyanobacteria are microrganisms capable of growing in polluted environments and their potential as agents of bioremediation of contaminated environments is promising. This study aimed to evaluate the potential

12. Efeito de alguns inseticidas sobre a mariposa Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) por meio de iscas esterilizantes. / Inseticide effects on the diamondback moth Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) by using sterilizing baits.
Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae), commonly known as diamondback moth, is an important pest of Brassicaceae in Brazil and several other countries. Its control is usually done with frequent applications of conventional insecticides. However, this approach is sometimes ineffective, besides some drawbacks such as environmental contaminat
