Hornworm, Erinnyis ello L. (Lepidoptera: Sphingidae), an defoliator insect that consumes cassava leaves in larval phase. In Brazil, is the most important pest of the culture. The control with Baculovirus erinnyis has been shown efficient and viable alternative, as environmental as economical point of view. The present work was accomplished in Bahia State, Brazil, from 2004 to 2006 in a 3.000 ha continuous area of cassava farming. The objective of this work is to verify the efficiency of the proposed monitoring for the control of the hornworm with B. erinnyis. The monitoring was accomplished counting the E. ello adults captured daily by luminous trap, and eggs and larvae presents in plants, after identification of adults flights (above 50 adults captured.day-1). It was considered as damage level (ND) the minimum number of two larvae per plant in second and third instar, when the control with B. erinnyis were done. The adults counting by luminous trap method was efficient in the identification of E. ello adult flights, and it allowed to optimize efficiently the eggs and larvae counting in the field when the infestations happened. With the proposed monitoring, it is possible the control of E. ello infestations with use of B. erinnyi.
