Conteúdo: |
The ground-pearl, Eurhizococcus brasthensis (Hempel in Wille), is a hypogeic hemipteran that feeds oil plant roots, being one of the major pests of vineyards. Ant species may account for the dispersal of scale insects, since the ants tend first instar nymphs for honeydew. This research was conducted to investigate, Under experimental conditions, whether the ants also recognize and carry E. brasiliensis cysts. Therefore, choice experiments were condueted in two vineyards naturally infested with the ground-pearl, in the municipality of Bento Goncalves, RS. From the 11 ant species observed visiting the cysts Only two were actively dispersing them, Linepithema micans (Forel 1908) and all unidentified Pheidole species. This Phedole species and the L. micans removed and carried L brasiliensis cysts. The workers of L. micans visited the greatest amount of test plates, but the Phedole sp. 11 workers removed more cysts. Although both species were more active to disperse the hemipteran's cysts, L. micans workers were dominant in reference to the workers of Phedole sp. 11. Thus, in the vineyards where they occurred together; if the first species is controlled, the second species call become the main E. brasiliensis disperser. |
