Flutuacao populacional de Acanthoderes jaspidea (Germar, 1824) (Coleoptera-Cerambycidae) em pomar de abacateiro (Persea americana, Mill)

This study was carried out to determine the meteorological agents influence on the populational fluctuation of Acanthodera jaspidea (Germar, 1824) in avocado orchard of Wagner variety at about 15 years old. This variety composes the guatemalen strain, floral group A. The experimental area was composed by 2 ha in Piracicaba, Sao Paulo state. The collection were gathered weekly with traps made of plastic botlles. The traps were boited with sugar cane syrup at 20 percent. There were 10 traps per ha put out from June, 1983 to May, 1985. From October to January there larges populations with 51 of all adults collected were trapped at this time. The trap and the boit were quite efficient reducing by the number of (31 percent) adults from one year to the next. There was no indication any of the meteorological agents studied has any influence on the fluctuation of the species.
