Abstract
A study by the Department of Primary Industries and Regional Development (DPIRD) was undertaken with the aim to better manage insecticide resistance in the cluster caterpillar (Spodoptera litura). Cluster caterpillar is an endemic armyworm species in WA, particularly in the State’s north, which affects a wide range of host plants including table grapes, capsicums, aubergine, cow peas, mung beans, maize, cotton and asparagus. The work was undertaken in response to field reports, from northern Western Australian horticultural regions, that some commonly used insecticides no longer provide adequate control, raising concerns that resistance has developed to some insecticides.
