Abstract Alternanthera philoxeroides (Mart.) Griseb. is an invasive herbaceous amphibious weed species in China. A pyralid moth Herpetogramma basalis (Walker) was discovered feeding on A. philoxeroides through field surveys and may be a potentially useful biocontrol agent. To determine the host range of H. basalis and evaluate its potential to control A. philoxeroides, no-choice and multiple-choice tests were conducted. Herpetogramma basalis fed on target weeds and 29 nontarget plant species. In addition to the target weed A. philoxeroides, H. basalis developed to adult on eight other nontarget species. Herpetogramma basalis survived to adulthood successfully on A. philoxeroides and less successfully on several other Amaranthaceae species. In multiple-choice studies, H. basalis showed a strong oviposition preference for A. philoxeroides over Amaranthus tricolor L. (Centrospermae: Amaranthaceae). Amaranthus tricolor was the only crop plant that supported the complete development of H. basalis. We cautiously recommend H. basalis for the biological control of A. philoxeroides in China.

Uraba lugens (gum leaf skeletoniser) is a serious pest of Eucalyptus spp in Australia It is now well established in the greater Auckland region and is spreading Two parasitoid species are under consideration as potential biological control agents of U lugens This paper describes host range testing methods developed using one of these species (Cotesia urabae) against two nontarget species Helicoverpa armigera and Spodoptera litura Using sequential nochoice tests to test the response of mated C urabae females clear preferences were observed for U lugens over both nontarget test species Some females did attempt to attack the nontarget species but no evidence of parasitism was observed when nontarget hosts were reared or dissected This method elucidated both behavioural responses and physiological development of C urabae and it is proposed to be a suitable host range testing method for full evaluation of this species
