This study evaluated the effectiveness of a rehabilitation program performed during working hours on function and pain in workers with subacromial impingement syndrome. Fourteen male workers (31.93 AE 5.86 years) in the school supply industry were assessed. The duration of their shoulder pain was 28.50 AE 33.64 months, and their amount of time in this industry was 9.07 AE 3.68 years. The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire evaluated function of the upper limbs. The McGill Pain Questionnaire quantified the pain by the number of words chosen and the pain rating index (PRI). Subjects completed an 8-week rehabilitation program, twice a week, consisting of cryotherapy, strengthening, and stretching exercises. Subjects' outcome data were collected pre-and post-intervention. The results showed that DASH scores improved (po0.05) and the number of words chosen and PRI decreased (po0.05) on the McGill Pain Questionnaire at post-intervention. Results should be interpreted cautiously, considering the lack of a control group in the investigation. In conclusion, it is suggested that an intervention program consisting of cryotherapy, strengthening, and stretching applied during working hours and twice a week may be effective to decrease pain and physical impairment in male workers with subacromial impingement syndrome.
-The aim of this research was to evaluate the biological behaviour of melonworm at different natural and artifi cial diets. Squash cultivar jacaré, cucumber, summer squash and an artifi cial diets developed by Hensley & Hammond for the sugarcane borer were tried. The research was carried out in the Laboratório de Entomologia do Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, in climatized room at 25 ± 1ºC, relative humidity of 70 ± 10% and 14h photofase. The caterpillars fed on each substrate during the whole life cycle. Differences in duration of the larval period, larvae and pupae survival, adult longevity and number of eggs were registered between the substrates. The results show that the best diet for rearing is the artifi cial one. Between the natural diets the cucumber showed the best results.KEY WORDS: Insect, biology, natural diet, artifi cial diet RESUMO -Aspectos biológicos de Diaphania hyalinata L. foram estudados quando as lagartas foram criadas em dietas natural e artifi cial em condições de laboratório, a 25 ± 1ºC, umidade relativa de 70 ± 10% e fotofase de 14h. Como dieta natural foi utilizada abóbora jacaré, pepino e abobrinha caserda e uma dieta artifi cial utilizada em criações de Diatraea saccharalis (Fabr.), desenvolvida por Hensley & Hammond. As lagartas de D. hyalinata foram colocadas nos diferentes substratos e criadas por todo o ciclo. Observaram-se diferenças na duração do período larval, sobrevivência das larvas e pupas, longevidade do adulto e número de ovos entre os substratos. A dieta artifi cial a que mostrou de modo geral, mais adequada para a criação de D. hyalinata. Entre as dietas naturais, o pepino foi o que se apresentou mais adequado para criação desta praga. PALAVRAS-CHAVE: Biologia, inseto, dieta natural, dieta artifi cial As plantas olerícolas pertencentes à família das cucurbitáceas constituem alimento de grande importância econômica e social, principalmente em áreas tropicais, já que seus frutos possuem altos teores de açúcares, vitaminas e amido (Saturnino et al. 1982). Das espécies cultivadas no Brasil, as abóboras, melancias, melões e pepinos exigem grandes investimentos devido à freqüente ocorrência de pragas e doenças (Filgueira 2003).As brocas Diaphania nitidalis Cramer e Diaphania hyalinata L. (Lepidoptera: Crambidae) são consideradas pragas-chave em cucurbitáceas, causando perdas que podem chegar, em algumas situações, até 100% de perdas da produção (Picanço & Marquini 1999, Picanço et al. 2000. Para contornar tais problemas, o controle dessas pragas tem sido tradicionalmente realizado através da aplicação de inseticidas químicos (Pratissoli 2002). O uso intensivo desses produtos pode provocar o ressurgimento da praga alvo, bem como o aparecimento de novas pragas, já que a maioria dos inseticidas utilizados possui amplo espectro biológico e persistência no ambiente, prejudicando a saúde do consumidor e dos profi ssionais envolvidos nos processos de produção (Brito et al. 2004).Objetivando a busca de medidas alternativas ao cont...

Bugs such as Nezara viridula (Linnaeus) and Dichelops melacanthus (Dallas) are considered the main insect pests of wheat crop in Brazil. The use of the entomopathogenic fungus Metarhizium anisopliae (Metschnikoff) may be an alternative for the management of these insects in the crop. The objective of this work was to verify the pathogenicity of different isolates of M. anisopliae on adults of N. viridula and D. melacanthus under laboratory and greenhouse conditions. In the laboratory, isolates 05RA, 11RA, 08RA and 02RA were obtained from N. viridula and D. melacanthus infested with M. anisopliae. Also, a high pathogenicity (100% of mortality) of both species was recorded in a bioassay of the topical application 8 Days After Application (DAA). However, compared to the other isolates, the 08RA isolate showed the highest pathogenicity in a shorter time interval for N. viridula (Mean Time “MT” = 2.8 days) and D. melacanthus (MT = 4.0 days). Under greenhouse conditions, the 08RA isolate provided a mortality of 44.9% (N. viridula) and 35.7% (D. melacanthus) in the same evaluation period. However, at 14 DAA, the mortality was 100% for both species, with the MT values of N. viridula and D. melacanthus being obtained at 8 days and 10 days, respectively. The fungus M. anisopliae is a promising alternative for the control of adult N. viridula and D. melacanthus in wheat crop.
