Influência de protetores solares na persistência do Baculovirus.

Abstract

The mandorová E. ello, is considered the pest of greatest importance in heveiculture in our region, due to defoliation in extensive areas. The biological control currently stands out because it does not pollute the environment and can use resources from the area itself, such as Baculavirus erinnyis. The experiment was set up in a rubber clonal garden on the campus of the Faculdade de Ciências Agrárias do Pará, where the pathogen was sprayed on rubber tree leaves, with different substrates. The experiment consisted of 3 treatments with 4 repetitions, which were: T1 = Bac + Clay; T2=Bac, + Ground Charcoal; T3 = Baculovirus. The dosage used was lEL/113.1362 lH20. After spraying the following periods were used: 24 h, 72 h and 168 h. Evaluations were made daily. It was concluded that the period of 72 h, presented higher persistence for Baculovirus after its application, and the sunscreens (Clay + Charcoal), did not increase the persistence period of Baculovirus.
