Bagrada bug, Bagrada hilaris, is an invasive stink bug spreading through western Arizona and southern California since 2008, causing severe crop, nursery, and landscape losses. Bagrada bugs gather on plants in large groups. In agriculture, Bagrada bug is a pest of cole crops and other mustard family plants.
Nothing serious, just a Brochymena arborea, otherwise known as the Rough Stink Bug. Rough Stink Bugs are not harmful as these beneficial predators prey on caterpillars, plant eating larvae of beetles, adult beetles, aphids and other soft-bodied insects with their piercing and sucking mouthparts.
Identifying Brown Marmorated Stink Bugs. The adult brown marmorated stink bug is shield shaped with brown mottling. It is between 14 and 17 mm long, roughly the size of a U.S. dime. Its abdominal edges and last two antennal segments have alternating broad light and dark bands.
The green stink bug's color is typically bright green, with narrow yellow, orange, or reddish edges. It is a large, shield-shaped bug with an elongate, oval form and a length between 13–18 mm. It can be differentiated from the species Nezara viridula by its black outermost three antennal segments.
In agriculture, stink bugs have been more of a problem in Mid-Atlantic states like Delaware, Maryland and Virginia. The U.S. Apple Association estimated that stink bugs caused $37 million in damage to apple growers in Maryland, Pennsylvania, Virginia and West Virginia in 2010.
The rice stink bug, Oebalus pugnax, is a flying insect in the shield bug family Pentatomidae native to North America that has become a major agricultural pest in the Southern United States. It has been a known pest since at least the time of Johan Christian Fabricius, who described the species in 1775.
Pentatomidae are a family of insects belonging to the order Hemiptera, which are generally called stink bugs or shield bugs (members of the sister family Acanthosomatidae are also called "shield bugs"). The name Pentatomidae is from the Greek pente meaning five and tomos meaning section, which refers to the five segments of their antennae.
The southern green stink bug is a highly polyphagous feeder, attacking many important food crops. Figure 1. Adult southern green stink bug, Nezara viridula (Linnaeus).
