Falling of berries bored by Hypothenemus hampei (Ferrari) may be the major loosing factor during the fruiting period. However, only those bored berries which remain in the soil surface before a new yielding period have been recognized as responsible for the damage level Ho achieved by new developing berries. In this paper, we investigated in the plants and in the soil surface, the presence of Coffea canephora cv. Conilon berries bored by H. hampei during the yielding period in Ouro Preto d'Oeste, Rondônia, Brazil. We took samples, weekly, from December 2000 to June 2001. The data were submitted to the Surviving Regression Analysis, based on a censored Weibull model. During the yielding period, berries fall down continuously and, in average, the proportion of H. hampei bored berries was 4 to 20 times higher in the soil (P &lt; 2,3 x 10-18, n = 62,747) than in the plants. Thus, we argue that adding the "soil environment" to the integrated management strategies could point to new technologies for the control of this insect.
