Predatory stink bugs

Definition

Members of the subfamily Asopinae (family Pentatomidae) characterized by raptorial forelegs adapted for seizing prey and predatory feeding habits, in contrast to the phytophagous majority of stink bugs. These hemipterans actively hunt caterpillars, beetle larvae, and other soft-bodied insects, functioning as important biological control agents in agricultural and natural ecosystems.

Etymology

From Latin praedator (plunderer, hunter) + English 'stink bug' referring to defensive scent glands; Asopinae from Greek asopos (name of a river, used taxonomically without predatory connotation)

Example

The Florida predatory stink bug Euthyrhynchus floridanus is deployed in citrus groves to control lepidopteran pests, while Podisus maculiventris (spined soldier bug) is mass-reared for augmentative biological control of Colorado potato beetle larvae.

Synonyms

Usage Notes

Not all predatory pentatomids are Asopinae, and not all Asopinae are strictly predatory—some supplement with plant fluids. The term is often used interchangeably with 'soldier bugs' in North American agricultural contexts, though 'soldier bug' properly refers to certain Podisus species. Contrast with 'plant-feeding stink bugs' or 'phytophagous Pentatominae' to clarify ecological role.
