Development and validation of formulations containing entomopathogenic nematodes for application on infested cattle Losses caused by the parasitism by ticks in cattle are estimated at 3.24 billion dollars annually in Brazil, largely due to procedural errors, such as the systematic and often inappropriate use of acaricides, resulting in selection and proliferation of populations of acaricide-resistant ticks. In addition, there is a growing demand for new alternatives in pest control, aiming at minimum use of chemicals, in order to preserve the environment and ensure residue-free food. In this context, biologic Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2014
Predatory capacity and bioecological aspects of the Chrysoperla externa (Neuroptera: Chrysopidae) and its preys Sipha flava and Ropalosiphum padi (Hemiptera: Aphididae) in forage crops The pest aphids Sipha flava and Rhopalosiphum padi have caused significant injuries in elephantgrass and brachiaria swards, respectively. Thus, the objective of this project was to evaluate the bioecology of these pest insects and the predator Chrysoperla externa. The biological aspects of the pests were studied at 12, 16, 20, 24, 28 and 32ºC. Temperatures of 20ºC and 24ºC were more favorable for insect development, and this temperature range is the most appropriate for t ... Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007
Plan of management for laboratorial biological waste: adequacy with standards in Good Laboratory Practice The adoption of Good Laboratory Practices (GLP) contributes to the development of scientific research, as they result in greater reliability and efficiency of the results. In order to follow some of the current standards, such as GLP or ISO 17025, the laboratory must adopt measures of organization, control, training, standardization and registration of its activities. The laboratory must also adopt practices that guarantee the safety of its personnel and the community in general. Among these is Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008
Molecular characterization of cattle tick population resistance to the main acaricides in Minas Gerais state, Brazil Bovine tick parasitism is a determinant of estimated losses of US $ 3.4 billion annually in Brazil. Much of these losses are due to mistakes made in the controlling attempts. The three main mistakes made are the use of an inappropriate acaricide at the wrong time and in the wrong way. In view of this situation, Embrapa Dairy Cattle implemented the acaricide effectiveness testing, a free service based on the determination of the most suitable product for application in each property, based on sam Status: Completed Start date: Sun Jun 01 00:00:00 GMT-03:00 2008
