FLUTUAÇÃO 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 of 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 collections were gathered weekly with traps made of plastic bottles. The traps were baited with sugar cane syrup at 20%. There were 10 traps per ha put out from June, 1983, to May, 1985. From October to January large populations with 51 of all adults collected were trapped at this time. The trap and the bait were quite efficient reducing by the number of (31%) adults from one year to the next. There was no indication that any of the meteorological agents studied had any influence on the fluctuation of the species.
