Studies of Heliothis mobility at Narrabri, summer 1989/90

Date Issued:1990-08-08

Abstract

Information about the frequency and intensity of immigration and emigration movements is essential for forecasting Heliothis infestation levels in crops, and thus for developing more efficient strategies for managing this pest. In particular, there is a specific need for this information for incorporation into computer models of Heliothis population processes that are being developed as aids to pest managers (Dillon & Pitt 1990). To meet this need, a comprehensive study of Heliothis movement is being undertaken at Narrabri Agricultural Research Station by researchers from CSIRO's Division of Entomology. In this paper, we outline the research methods being used and present some preliminary results for the first full season of observations, 1989/90
