Leptocorisa acuta, [1] the paddy earhead bug, [2] is a species of bug recorded from northern Australia, Malesia and Taiwan. [3] Its basionym is Cimex acutus and it is now placed in the family Alydidae. One of several rice bug species, it may be confused with Leptocorisa oratoria .

Pest status

Rice bugs can be a significant pest of the rice plant, as they feed-on developing (milk stage) grains: reducing crop quality and sometimes yield. Because attacks occur near to harvest, if farmers spray insecticides in an attempt to control outbreaks, they risk leaving harmful pesticide residues on the crop.

It is also a pest of sorghum, pearl millet, and finger millet in Asia. [2]

Rice Staple grain of Oryza and Zizania species

Rice is the seed of the grass species Oryza sativa or less commonly Oryza glaberrima. The name wild rice is usually used for species of the genera Zizania and Porteresia, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.

Millet Group of grasses (food grain)

Millets are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa.

Proso millet Species of plant

Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where about half a million acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet. Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass subfamily Panicoideae. While all of these crops use C4 photosynthesis, the others all employ the NADP-ME as their primary carbon shuttle pathway, while the primary C4 carbon shuttle in proso millet is the NAD-ME pathway.

<i>Eleusine coracana</i> Species of grass

Eleusine coracana, or finger millet, also known as ragi in India, kodo in Nepal, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.

Crambidae Family of moths

The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes.

Pearl millet Species of cultivated grass

Pearl millet is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC.

Foxtail millet Species of grass

Foxtail millet, scientific name Setaria italica, is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity.

<i>Echinochloa frumentacea</i> Species of grass

Echinochloa frumentacea is a species of Echinochloa. Both Echinochloa frumentacea and E. esculenta are called Japanese millet. This millet is widely grown as a cereal in India, Pakistan, and Nepal. Its wild ancestor is the tropical grass Echinochloa colona, but the exact date or region of domestication is uncertain. It is cultivated on marginal lands where rice and other crops will not grow well. The grains are cooked in water, like rice, or boiled with milk and sugar. Sometimes it is fermented to make beer. While also being part of staple diet for some communities in India, these seeds are, in particular, eaten during religious fasting. For this reason, these seeds are commonly also referred to as "vrat ke chawal" in Hindi. Other common names to identify these seeds include oodalu (ಊದಲು) in Kannada, Shyamak (শ্যামাক) or Shyama Chal in Bangla, jhangora in the Garhwal Hills, bhagar (भगर) in Marathi-speaking areas, samo or morio seeds in Gujerati, or kuthiraivaali (குதிரைவாளி) in Tamil.

<i>Echinochloa</i> Genus of flowering plants in the grass family

Echinochloa is a very widespread genus of plants in the grass family and tribe Paniceae. Some of the species are known by the common names barnyard grass or cockspur grass.

Alydidae Family of true bugs

Alydidae, commonly known as broad-headed bugs, is a family of true bugs very similar to the closely related Coreidae. There are at least 60 genera and 300 species altogether. Distributed in the temperate and warmer regions of the Earth, most are tropical and subtropical animals; for example Europe has a mere 10 species, and only 2 of these occur outside the Mediterranean region.

<i>Paspalum scrobiculatum</i> Species of grass

Paspalum scrobiculatum, commonly called Kodo millet or Koda millet, is an annual grain that is grown primarily in Nepal (not to confuse with Kodo and also in India, Philippines, Indonesia, Vietnam, Thailand, and in West Africa from where it originated. It is grown as a minor crop in most of these areas, with the exception of the Deccan plateau in India where it is grown as a major food source. It is a very hardy crop that is drought tolerant and can survive on marginal soils where other crops may not survive, and can supply 450–900 kg of grain per hectare. Kodo millet has large potential to provide nourishing food to subsistence farmers in Africa and elsewhere.

<i>Panicum sumatrense</i> Species of grass

Panicum sumatrense, known as little millet, is a species of millet in the family Poaceae.

<i>Oebalus pugnax</i> Species of true bug

Oebalus pugnax, the rice stink bug, 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.

Micraspis discolor is a species of ladybird. It was described by Johan Christian Fabricius in 1798. It is widespread throughout Asia, North America and parts of Oceania.

<i>Leptocorisa oratoria</i> Species of true bug

Leptocorisa oratoria, the rice ear bug, is an insect from the family Alydidae, the broad-headed bugs. This species is commonly confused with Leptocorisa acuta, and other similar, related "rice bug" genera and species.

<i>Musgraveia sulciventris</i> Species of true bug

Musgraveia sulciventris is a large stink bug found in Australia, sometimes known as the bronze orange bug. It is considered a pest, particularly to plants in the citrus group. Bronze orange bugs suck the sap from trees, which causes the flowers and fruit to fall.

<i>Leptocorisa</i> Genus of true bugs

Leptocorisa is a genus of broad-headed bugs in the family Alydidae. There are about 17 described species in Leptocorisa, some of which are known as "rice bugs" or gundhi bugs ; they are found in south and east Asia and in Oceania.
