Abstract
Using Aeneolamia varia saccharina (Distant), a pest of sugar cane in Trinidad, a technique is described for determining the net reproductive rate from time series of stage recruitment data in consecutive generations. It is assumed that the recruitment data was collected in the field at irregular intervals, every few days, throughout each generation. The method can account for the effect of pesticide applications and climatic disturbances and a set of field data is presented as an illustration.
