Measures to control the cattle tick, Rhipicephalus (Boophilus) microplus, based only on chemical products are becoming unsustainable, mainly because of the development of resistance. The objective of this study was to test the effect of the aqueous extract of pineapple skin (AEPS) and bromelain extracted from the stem (Sigma?Aldrich®, B4882) on engorged females and larvae of R. (B.) microplus in vitro. These substances were diluted in water and evaluated at eight concentrations. Engorged females were collected and distributed in groups of 10, with three repetitions for each treatment. After immersion in the solutions, the females were placed in an incubator for observation of survival, oviposition and larval hatching. The larval packet method was used, also with three repetitions with about 100 larvae each. The packets were incubated and the readings were performed after 24 h. The estimated reproduction and efficacy of the solutions were calculated. The LC50 and LC90 were estimated using the Probit procedure of the SAS program. The eight concentrations were compared within each treatment by the Tukey test. For the experiment with engorged females, the most effective concentrations were 125, 250 and 500 mg/mL: 33%, 48% and 59% for the AEPS and 27%, 51% and 55% for the bromelain. The LC50 and LC90 values were, respectively, 276 and 8691 mg/mL for AEPS and 373 and 5172 mg/mL for bromelain. None of the dilutions tested was effective against the larvae of R. (B.) microplus. This is the first report of the action of pineapple extracts or their constituents on cattle ticks. The results demonstrate that further studies regarding composition of tick cuticle, with evaluation of other solvents and formulations, should be conducted seeking to enhance the effect of pineapple extracts and compounds against this ectoparasite.

Descreve-se um método que, a partir de dados diários de temperatura e umidade relativa do ar, velocidade do vento, temperatura de ponto de orvalho, precipitação, insolação e quantidade de focos de incêndio, determina qual o melhor método a ser usado, entre cinco, para o cálculo de risco de incêndio na região em questão. A partir dos métodos: Fórmula de Monte Alegre (FMA), FMA Modificado (FMA+), Nesterov, Telicyn e Angstron, o sistema seleciona o que melhor prediz o risco de incêndio, além de, quando possível, determinar um fator para melhorar oresultado à região alvo, utilizando análise estatística dos erros. Os resultados do método podem sair em html ou em arquivo csv (comma separated values). This paper describes a method that choose the best method to calculate the fire risk index for region, among: FMA, FMA+, Nesterov, Telicyn and Angstron. The inputs of this system are temperature and moisture from the air, wind velocity, dew point temperature, rainfall, solar radiation and fire focus number. The selection of the best index is made by statistical analysis of errors and by multiply the best equation by additional equation. With the best method, the system try to improve the result adding an equation (adjustment factor) to the method. The results of this system can be html format or csv (comma separated values) file. |
