Poecilus Chalcites
''Poecilus chalcites'' is a species of woodland ground beetle in the family Carabidae. It is found in the Caribbean, Central America, and North America, and is common in cropland of Illinois and other states. ''Poecilus chalcites'' is a carnivourous species known to eat various crop pests including Diabrotica virgifera virgifera The Western corn rootworm, ''Diabrotica virgifera virgifera'', is one of the most devastating corn rootworm species in North America, especially in the midwestern corn-growing areas such as Iowa. A related species, the Northern corn rootworm, ''D ..., Helicoverpa zea, Agrotis ipsilon, and Mythimna unipuncta. Males and females can be distinguished by the shape of the most proximate foretarsus. In males, it is heart-shaped, but in females it is thinner.

Carabidae
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are phytophagous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their fore leg tibiae bearing a comb of hairs used for cleaning their antennae.

Diabrotica Virgifera Virgifera
The Western corn rootworm, ''Diabrotica virgifera virgifera'', is one of the most devastating corn rootworm species in North America, especially in the midwestern corn-growing areas such as Iowa. A related species, the Northern corn rootworm, ''D. barberi'', co-inhabits in much of the range and is fairly similar in biology. Two other subspecies of ''D. virgifera'' are described, including the Mexican corn rootworm (''Diabrotica virgifera zeae''), a significant pest in its own right, attacking corn in that country. Corn rootworm larvae can destroy significant percentages of corn if left untreated. In the United States, current estimates show that of corn (out of 80 million grown) are infested with corn rootworm. The United States Department of Agriculture estimates that corn rootworms cause $1 billion in lost revenue each year, including $800 million in yield loss and $200 million in cost of treatment for corn growers. Life cycle There are many similarities in the life cycles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicoverpa Zea
''Helicoverpa zea, ''commonly known as the corn earworm, is a species (formerly in the genus ''Heliothis'') in the family Noctuidae. The larva of the moth ''Helicoverpa zea'' is a major agricultural pest. Since it is polyphagous (feeds on many different plants) during the larval stage, the species has been given many different common names, including the cotton bollworm and the tomato fruitworm. It also consumes a wide variety of other crops. The species is widely distributed across the Americas with the exception of northern Canada and Alaska. It has become resistant to many pesticides, but can be controlled with integrated pest management techniques including deep ploughing, trap crops, chemical control using mineral oil, and biological controls. The species migrates seasonally, at night, and can be carried downwind up to 400 km. Pupae can make use of diapause to wait out adverse environmental conditions, especially at high latitudes and in drought. Distribution ...

Agrotis Ipsilon
''Agrotis ipsilon'', the dark sword-grass, black cutworm, greasy cutworm, floodplain cutworm or ipsilon dart, is a small noctuid moth found worldwide. The moth gets its scientific name from black markings on its forewings shaped like the letter "Y" or the Greek letter upsilon. The larvae are known as "cutworms" because they cut plants and other crops. The larvae are serious agricultural pests and feed on nearly all varieties of vegetables and many important grains.Capinera, John L"Common Name: Black Cutworm" ''Entomology and Nematology'', University of Florida, October 2006. This species is a seasonal migrant that travels north in the spring and south in the fall to escape extreme temperatures in the summer and winter. The migration patterns reflect how reproduction occurs in the spring and ceases in the fall. Females release sex pheromones to attract males for mating. Pheromone production and release in females and pheromone responsiveness in males is dependent on the juvenile h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mythimna Unipuncta
''Mythimna unipuncta'', the true armyworm moth, white-speck moth, common armyworm or rice armyworm, is a nocturnal agricultural pest belonging to the family Noctuidae. This moth is also commonly referred to by the scientific name ''Pseudaletia unipuncta''. The species was first described by Adrian Hardy Haworth in 1809. ''Mythimna unipuncta'' is found in the Americas and in parts of Europe, Africa and Asia. Its original distribution is North and South America. It has been introduced to other places from there. They are known as armyworms because the caterpillars move in lines as a massive group, like an army, from field to field, damaging crops.Palmer, Geoff (July 23, 2012)"Pest Alert - Armyworms Round Two Hit Hay and Corn Crops" ''Agriculture and Market''. The true armyworm has a distinct migration pattern in which they travel north in the spring and south in the fall to ensure that mating occurs in a favorable environment in the summer.

Pterostichinae
Pterostichinae is a subfamily of ground beetles (family Carabidae). It belongs to the advanced harpaline assemblage, and if these are circumscribed ''sensu lato'' as a single subfamily, Pterostichinae are downranked to a tribe Pterostichini. However, as the former Pterostichitae supertribe of the Harpalinae as loosely circumscribed does seem to constitute a lineage rather distinct from '' Harpalus'', its core group is here considered to be the present subfamily and the Harpalinae are defined more narrowly. They are usually mid-sized and rather stout ground beetles. Coloration is typically dark and without conspicuous patterns, but often with a strong sheen like polished metal. They are widely distributed and inhabit a wide range of terrestrial habitats. Unlike the more basal ground beetles which only eat small animals, the Pterostichinae include a large proportion of omnivorous or even herbivorous taxa. Systematics This group includes the following tribes and genera: Tribe A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
