Spined soldier bug

Carboxylesterases are responsible for the selective toxicity of malathion that favors mammals over insects. Carboxylesterase hydrolyzing trans-permethrin has been found in numerous insect species, including the fall armyworm, velvetbean caterpillar (Anticar-sia gemmatalis), cabbage looper (Trichoplnsia ni), tobacco budworm (Heliothis virescens), corn earworm (Helicoverpa zea), and spined soldier bug (Podisus maculwentris) (Yu, 1990).

Many kinds of stink bugs are pests, but spined soldier bugs are voracious predators of a variety of caterpillars and grubs. 

Control Prune infested branches and burn them, or remove tents filled with caterpillars from branches by winding them onto a broomstick with nails projecting from it in winter, remove egg masses from bare branches attract native parasitic flies and wasps by growing small-flowered herbs, such as catnip, and wildflowers, such as Queen Anne s lace. Do not destroy wandering caterpillars with white eggs or cocoons attached to their backs they are hosts for native parasites. Spray BTK weekly while larvae are small try releases of spined soldier bugs. 

Spined soldier bug Podisus maculivenths Fall armyworms, hairless caterpillars, including tent caterpillars, sawfly larvae beetle larvae such as those of Colorado potato beetle and Mexican bean beetle. These resemble stink bugs, but spined soldier bugs have sharp points on the "shoulders" of the thorax. Maintain permanent beds of perennials to provide shelter.
