Taxonomy
It has historically been placed in the genus Acrosternum , but according to Dr. David Rider of North Dakota State University and other experts, this placement is not accurate; the name of the genus Acrosternum should be limited to a handful of Old World, small, pale green species that live in dry dry regions, whereas larger and lighter green species living in the Old and New Worlds should go by the genus name Chinavia , therefore this species is called Chinavia hilaris in more recent literature (eg, Schwertner and Grazia, 2006).

Description
The color of the green smell insects is usually bright green, with a narrow yellow, orange, or reddish edge. It is a large insect shaped shield with elongated shape, oval and length between 13-18 mm. It can be distinguished from the species Nezara viridula by the three segments of its outermost black antenna. Pronolateral margins (= in front and far from the center) are pronotal somewhat straight and not as strongly curved as in Acrosternum pennsylvanicum .
Both adults and nymphs have a large odor gland at the bottom of the thorax that extends over halfway to the edge of the metapleuron. They secrete large amounts of this foul-smelling fluid when disturbed. This liquid, dried and crushed, was once used at the industrial level to reinforce the smell of some acids. Now it's been replaced by an artificial composite.
Habitat
It is found in gardens, gardens, forests and crop fields throughout North America, eating by mouth like their needles on juices from various plants from May to the arrival of frost. Adults develop preferences for developing seeds and thus become plant pests (tomatoes, beans, nuts, cotton, corn, soybeans, eggplants). When there is no seed, they also eat stems and leaves, thus destroying some fruit trees, such as apple trees, cherries, oranges and peaches. In addition, it can be found in Queensland and New South Wales. The green smell insects are bored with bonfire salvia as well as tomatoes and mulberries. Also been found in peach, apricot, wine, silver bits and french beans. The difference here is that they do not seem to be a pest to them.
Life cycle
Adults appeared on the field in early September and became many in a sheltered position. Then, the mating takes place in early October and finally, the eggs can be found mid to late October. Nymphs appear in late October and early November. Two or three generations occur in the summer in the field and in the laboratory at 26 ° C.
Reproduction
They attach a barrel-shaped egg at the bottom of the leaf in two rows of twelve eggs or more. The green odor bugs produce a generation in the North and two generations in the South. The early instar ancestor was somewhat brightly colored and striped, turning green as it approached adulthood. Eggs are usually placed in groups of 14 (some groups contain fewer eggs, with 9 being the smallest number recorded from 77 observations). Eggs are placed under leaf undersurfaces or on stems of plants or on salvia flowers.
Pest management
This is a parasite by tachinid fly Trichopoda pennipes . The green odor bugs use methyl pheromone (E, Z, Z) -2,4,6-nearrienoate in its communication system and this can be used to attract insects from crop fields.
