Moscas-das-frutas que oferecem riscos à fruticultura brasileira.

Moscas-das-frutas, são insetos-praga que atacam diferentes variedades de frutas, são insetos da ordem Diptera e pertencem á família Tephritidae

Biofábrica Moscamed Brasil: tecnologia ambientalmente segura no combate às pragas.

Conhecida também por mosca-do-mediterrâneo ou moscamed, a Ceratitis capitata (Weidemann) (Diptera: Tephritidae) é nativa da África Equatorial e encontra-se espalhada pela Europa, Américas, Caribe, Austrália e Ilhas do Pacífico (Metcalf et al., 1962). Foi constatada pela primeira vez no Brasil em 1901. É considerada uma das espécies de mosca-das-frutas mais nocivas à fruticultura mundial, pois apresenta grande plasticidade ecológica e evolutiva, adaptando-se rapidamente a novos hospedeiros e ambientes

A mosca-das-frutas e a comercialização de uvas.

Na região Sul do Brasil a espécie de mosca-das-frutas que ataca mais frequentemente os parreirais de uvas é a mosca-das-frutas sul americana

Efficiency of low versus high airline pressure in stunning cattle with a pneumatically powered penetrating captive bolt gun

The efficiency of stunning cattle was assessed in 443 animals (304 pure Zebu and 139 crossbred cattle), being mainly mature bulls and cows. Cattle were stunned using a Jarvis pneumatically powered penetrating captive bolt gun operating with low (160–175 psi, N = 82) and high (190 psi, N = 363) airline pressure, which was within the manufactures specifications. Signs of brain function and the position of the shots on the heads were recorded after stunning. Velocity of the captive bolt and its physical parameters were calculated. Cattle shot with low pressures showed more rhythmic respiration (27 vs. 8%, P < 0.001), less tongue protrusion (4 vs. 12%, P = 0.03) and less masseter relaxation (22 vs. 48%, P < 0.001). There was an increased frequency of shots in the ideal position when cattle were shot with the low compared to high airline pressures (15.3 vs. 3.1%). Bolt velocity and its physical parameters were significantly (P < 0.01) higher when using high pressure. Airline pressures below 190 psi are inappropriate when shooting adult Zebu beef cattle with pneumatically powered penetrating captive bolt guns

The negative influences of the new brazilian forest code on the conservation of riparian forests

More than one million hectares of riparian forests were degraded or altered in Mato Grosso State (Brazil) up&nbsp;to 2009. The aim of the research is to set a comparative scenario to show differences in the quantification of&nbsp;environmental liabilities in riparian forest areas resulting from the change in native vegetation protection rules&nbsp;due to the transition between Laws 4771/65 and 12651/2012. Data collection took place in a marginal stretch&nbsp;of Vermelho River in Rondonópolis County, Mato Grosso State. The following data set was taken into consideration:&nbsp;aerial images derived from unmanned aerial vehicle, Rapid Eye satellite images and orbital images hosted&nbsp;at Google Earth. The spatial resolution of those images was compared. The aerial photos composed a mosaic&nbsp;that was photo-interpreted to generate land use and occupation classes. The riparian forest areas of a rural&nbsp;property were used as parameter, and their environmental situation was compared in 05 meter and 100 meter&nbsp;strips. Thus, by taking into consideration the current rules, 23,501 m2 of area ceased to be an environmental&nbsp;liability within the riparian forest and became a consolidated rural area. According to the previous Forest Code,&nbsp;in a different scenario, that is, in a set of rural properties, the public authority would receive USD 68,600.00 in&nbsp;fines. The new Brazilian Forestry Code of 2012, which replaces the previous one made in 1965, exempts those&nbsp;responsible for rural property from regenerating previously deforested native vegetation — an obligation established&nbsp;by older Forest Code. We have shown that the new Forest Code has diminished the legal responsibility of&nbsp;the rural owners in relation to the maintenance of forest fragments in their properties

Técnica do inseto estéril e controle biológico: métodos ambientalmente seguros e eficazes no combate às moscas-das-frutas.

As moscas-das-frutas (Diptera: Tephritidae) são as principais pragas de plantas frutíferas em todo o mundo, pois além do dano direto causado na polpa dos frutos também é responsável por barreiras quarentenárias impostas por países importadores de frutos frescos
