impact of sex pheromones, stirrup-m as additive for acaricides effects were evaluated on panonycjllls lllmi in 1995-1997. peroral (azocyclotin), amitraz (mitac), omite (propargite), neoron (bromopropylate) and citrazon (benzoximate) were tested with and without pheromones and compared with untreated plots with four replications through randomized complete block design. mortality percentage of e...

Air: Propargite has very negligible vapor pressure (3.89 x 10 mmHg); therefore, it is not readily volatilized into the atmosphere. The low Henry’s law constant, <9.43 x 10 atmmg.mol at 25C, indicates that propargite is unlikely to volatilize into air from an aqueous solution (Lyman, et al., 1982). Aside from drift that is generated by spray applications, propargite is not expected to be found i...

This work compared the sensitivity of three cyanobacteria (Anabaena flos-aquae, Microcystis flosaquae and Mirocystis aeruginosa) as well as five green algae (Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa) to four pesticides through 96h short-term chronic tests. The results showed that the toxicity of the pesticides t...

Two hundred sediment samples were collected and their toxicity evaluated to aquatic species in a previous study in the agriculturally dominated Central Valley of California, United States. Pyrethroid insecticides were the main contributors to the observed toxicity. However, mortality in approximately one third of the toxic samples could not be explained solely by the presence of pyrethroids in ...

INTRODUCTION Investigators have hypothesized that consuming pesticide-contaminated well water plays a role in Parkinson's disease (PD), and several previous epidemiologic studies support this hypothesis. OBJECTIVES We investigated whether consuming water from private wells located in areas with documented historical pesticide use was associated with an increased risk of PD. METHODS We emplo...

The use of synthetic acaricides for management of pest mites may alter the efficacy of the ectoparasitoid Tamarixia radiata (Waterston) in biological control of Diaphorina citri Kuwayama, the vector of the bacteria associated with huanglongbing (HLB) in citrus orchards. We evaluated the toxicity of 16 acaricides that are recommended for the control of citrus-pest mites to T. radiata. Acrinathri...

El derecho constitucional actual ha desarrollado técnicas de interpretación que le son propias para evitar el uso herramientas hermenéuticas provenientes la legal, las cuales inadecuadas resolver conflictos en están involucrados derechos humanos. Entre estas se encuentra principio conforme a los objetivo del presente artículo es verificar su aplicación jurisprudencia chilena. Nuestra hipótesis ...

Resumen&#x0D; De modo restringido se comprende a la salud como ausencia de enfermedad. Este abordaje positivista omite los estilos vida y sus modos reproducirse que implicarían incorporar procesos sociales, históricos políticos por atraviesa corporalidad. La pretensión esta investigación es realizar dicha crítica.

the side-effects of amitraz, buprofezin and propargite were studied on encarsia formosa (gahan)in the laboratory, using a life table response experiment and the iobc system for their toxicity. bioassayswere conducted by dipping bean leaves containing third instar nymphs of the whitefly trialeurodesvaporariorum (westwood), parasitized by e. formosa, in insecticide solutions or caging adult paras...
