Aspectos biológicos da fase larval de Ceraeochryza ca!igala (Banks, 1946) (Neuroptera: Chrysopidae) alimentada com os hemípteros Ortheziapraelonga Douglas, 1891 (Ortheziidae), Planococcus citri (Rísso, 1813) (Pseudococcidae) e Brevicoryne hrassicae (L.,1758).

Abstract

Citrus field production is na agrucultural activity globally explored, not only for the production of the juice, but for the social organization. The production concentrates on the state of São Paulo, however, the state of Pará also participates of that production tends in 2005 your planted arca of 13,093 ha, producing a total of 213,972t, presenting médium revenue of 16,342Kg/ha, being the municipal districts of Capitão Poço and Irituia, the largest producers. The culture possesses several insect-curse that they attack causing it enormous damages as it defoliates her, the qeakness of the tree and fali of the fruits (more than 50%), being the remaining " watery" with low tenor of sugar and acid, disabling your fruits for commercialization. Of this it sorts things out, to combat such incidences it is necessary to throw hand of available resources in the own ecosystem, in other words, to use the biological control providing a possible more organicproduction, improving the environmental and human quality. Therefore, the appropriately correct biological control provides the balance in the environment, where predator and prey live in harmony um a relationship predator-prey, inside of your limits, because both need to survive executing the cycle of each one the middle. And among the species predators of insects phytofagous they exist the crisopid that adapt in laboratory conditions, favoringyour creation massal, and you research realative your predating capacity and functional answer can made. Before such facts, this research seeks to obtain larger Information as the preys used by this predator, because researchers seeks to obtain larger such phytofagous as greenflies, green bugs, eggs and caterpillars of lepidopterous, cicadas, write flies and black fly the citrus. However, the green bugs were used to know the behavior of the predator Ceraeochrysa ca!igala on this food type - Orlheziapraelonga e Planococcus citri - they will be tested as arrested.
