Fruitspotting bugs, A mblypelta nitida   S tål, and A . lutescens lutescens   Di stant ( H emiptera: C oreidae), are polyphagous, native A ustralian pests of a wide range of tropical and subtropical fruit and nut crops. Both species occur predominantly along A ustralia's eastern coastline, A . nitida from c. 17° S ‐35° S and A . l. lutescens from c. 11° S ‐27° S , and as such, they are distributed across some of A ustralia's most important horticultural regions. Adults are cryptic and highly mobile, making population monitoring within affected tree crops difficult. Nymphs and adults inject salivary sucrase into plant tissue while feeding; this causes significant damage to fruiting structures and often renders them unsaleable. Despite their economic importance, many aspects of fruitspotting bug biology and ecology remain understudied; their chemical ecology, host‐plant relationships, movements into, out of and within crops, and interactions with natural enemies are poorly understood. Currently, control of both species relies on applications of synthetic broad‐spectrum insecticides, and the recent withdrawal of endosulfan has resulted in an increased use of more disruptive compounds. This paper reviews current knowledge of fruitspotting bug biology and ecology, and the strategies that are currently employed for control. Importantly, a synthetic lure based on some of the volatile compounds emitted by male A . l. lutescens has recently been developed and incorporated into a prototype trap. The device offers a promising new approach to population monitoring and the development of integrated management strategies for this species. Areas of research critical to the development of sustainable management strategies for fruitspotting bugs include: (1) host‐plant relationships between fruitspotting bugs and their crop and non‐crop host plants; (2) fruitspotting bug dispersal behaviour and movement patterns between and within crops, and between crops and non‐crop vegetation; (3) methods for implementing biological control strategies; (4) utilising pheromone traps for monitoring and capture of fruitspotting bugs; and (5) screening of selective insecticides.
