In 1974, following the occurrence of DDT resistant H. armigera, a resistance monitoring program for Heliothis spp. was started at the Tamworth laboratories of the Department of Agriculture, NSW.

OBJECTIVES * To make a direct and impartial yield comparison between two types of drip irrigation and standard furrow irrigation.

This project was aimed at providing a rational approach to restoring soil structure after it becomes degraded under intensive irrigated cotton production. The specific aims were: 1.

A new monitoring technique has been devised which enables individual larvae to be screened for pyrethroid/endosulfan resistance directly from the field without changing their genetic makeup.
