摘要：

Woolly nightshade, Solanum mauritianum (Solanaceae) is a serious environmental and forestry weed in New Zealand. The leaf-feeding lace bug, Gargaphia decoris (Tingidae), was released in South Africa in 1999 after rigorous host specificity testing revealed that natives and crops ill the genus Solanum were unlikely to be attacked. All three New Zealand native Solanum spp. were similarly tested in South Africa. Neither Solanum laciniatum, Solanum aviculare (poroporo) nor Solanum americanum (small-flowered nightshade) supported feeding by nymphs or adults of G. decoris in no-choice tests. During multichoice tests, 97% of adults selected S. mauritianum, while 2% selected eggplant cv. Black Beauty (S. melongena). Oviposition occurred only on S. mauritianum. The risks of non-target attack are therefore low enough to warrant further evaluation of G. decoris as a biocontrol agent in New Zealand.
