Zygogramma
''Calligrapha'' is a large genus of Americas, American Chrysomelinae (a subfamily of leaf beetles), with over 100 species occurring from North America through Central America. Biology Some members of the subgenus ''Zygogramma'' are agricultural pests, while others are used as biological control agents. ''Calligrapha exclamationis'' is a pest species of sunflower crops in North America. At least two species have also been used as a form of biological pest control: ''Calligrapha bicolorata'' was introduced to India as a biocontrol agent for the weed ''Parthenium hysterophorus'', and ''Calligrapha suturalis'' was introduced to Russia as a control for ''Ambrosia artemisiifolia'' (common ragweed).

The Coleopterists Bulletin 78(2): 281-295. It is regarded as a pest of sunflower crops in North America. Description ''C. exclamationis'' is a small leaf beetle, 6–12 mm in length, 2–4 mm wide, with a brown pronotum and yellow elytra marked with three, elongated brown stripes and a single, shorter, lateral stripe ending at the middle of the wing in a small dot that resembles an exclamation point.

''Calligrapha bicolorata'', variously referred to as the Parthenium beetle or Mexican beetle, is a species of leaf beetle belonging to the family Chrysomelidae, in the subgenus ''Zygogramma'', which was formerly a genus.Shawn M.

The pattern on the elytra is greatly variable - in a study of 478 beetles, 29 variations on this pattern were identified. Distribution and habitat ''C. bicolorata'' is native to Mexico, but has been introduced to parts of India and Australia. Adults and larvae are used as a form of biological pest control in India in order to control invasive '' Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
