Abstract: | Thrips are one of the most difficult pests to control in seedling stage (Maria Calin, 2004, 2005). This pest is very dangerous insects that reproduce rapidly, congregate in tight places that make pesticide coverage difficult. After the insect feed, the results are the deformation of flowers and leaves (Maria Cãlin, 2004, 2005, Dreistadt and all., 2001, 2004, 2007).The tolerance of thrips on plants with multiple uses crops is low.
In addition, when Thrips tabaci feed on plants they usually infect the plant with the viruses as: Lycopersicon virus 3, Solanum virus 8, Nicotiana virus 1, Tomato Spotted wilt virus. Once plants are infected, it is too late to do anything except dispose of diseased plants. Thus, the best way to prevent virus infection is to control the thrips (Flint and all., 1998, Maria Cãlin, 2005).A regular monitoring program is the basis of all pest management programs. The best way is to conduct a regular, weekly monitoring program to detect problems in an early stage.
This early detection and treatment will result in better pest control since plant canopies are smaller and better spray coverage can be achieved. Plant inspection is needed to assess general plant health and to detect the pests (O´Donnell et all, 2005; Maria Cãlin, 2005). |
