Therefore, this study aimed to test the use of yellow card traps around the crop to manage insect vectors of viruses and test the best density of traps/tomato plants. Yellow card traps were placed on the border of the crop plot to capture adult insect vectors. Density of trap/tomato plant was assessed in 10 blocks at the following levels： 1/25; 1/50; 1/75; 1/100; 1/125; 1/150. The monitoring was carded out in 1% of the crop during 60 days in 2011 and 2012 crop. The evaluated systems were Conventional and Phytosanitary Pest Management （PPM）. During 2011 season the Conventional system received 14 insecticide applications whereas only 6 insecticide applications were made on the PPM, representing a reduction of 133%. In 2012, the crop under Conventional system was subjected to 15 applications of insecticides, over 8 on PPM, with a reduction of 87.5%. The PPM allowed a 90% reduction in application cost for this insects, obtaining a reduction of R$1,345.00/ha. The highest density was 60 plants/trap. We can conclude that the yellow card traps in tomato crop decreased infestations of insect vectors of viruses.展开更多

Topic： Polyarteritis nodosa is a disease more frequent in young men with a preceding acute viral hepatitis B which is AgHbs positive. The characteristic of this disease is the presence of many aneurysms at different sites of the small and medium size artery. It is possible for a palpable purpuric rash to appear at any time in the evolution of the disease. The histopathological examination represents the goal of the diagnosis. Method： The principals methods was to attain the desired result, a cerebral MRI was initially performed in order to view any brain malformations and also for excluded an ischemic or hemorrhagic stroke attack , this was followed via a cerebral vascular angiography, an abdominal ultrasound and CT scan, the results of which led to a renal artery angiography being performed, this led to the need to perform a cerebral artery angiography and finally a histopathological examination of the skin of the legs （biopsy）. Achievement： Through the above listed paramedical examinations I was able to prove the existence of multiple aneurysms in the cerebral arteries, renal arteries and small growth of the left kidney, this being a direct result of the aneurysms, this also meant disruption in kidney blood flow meaning, an increase in systemic blood pressure which was the manifest primary symptom the this young patient such as transitory stroke attack. The skin biopsy finally gave a certain diagnosis of Polyarteritis Nodosa.展开更多
