Clavigralla gibbosa, the tur pod bug,[ citation needed ] is a species of leaf-footed bug in the family Coreidae. It is found in India, Sri Lanka and Myanmar, where it is a pest of pigeon pea (Cajanus cajan). [1]
Clavigralla gibbosa occurs in India, Sri Lanka and Myanmar, where the adults and nymphs feed on pigeon pea. [2]
As a hemipteran, this species is hemimetabolous, meaning that it does not undergo metamorphosis. Instead, the young are called nymphs. They moult several times, and each instar resembles the adult more than the previous one. Eggs are laid in clutches of five to ten on leaves and pods of the host plant, three or four hundred eggs being laid by each female over a period of five months. The eggs hatch in four to twenty days, nymphal development taking 4.3 days in May and 20 days in January. Generations show considerable overlap and up to six generations can occur between November and May. Although adult insects can live on other leguminous plants, nymphal development only takes place on pigeon pea. [3]
Pigeon pea is an important leguminous crop in semi-arid areas of tropical and subtropical India, ranking second behind chickpeas. The plant is a perennial, has a long tap root and can thrive in drier conditions than maize and millet. The seeds of pigeon pea contain high levels of protein and the amino acids methionine, lysine, and tryptophan; [4] they are eaten fresh or dried, the hulm is fed to livestock and the woody parts of the plant are used for firewood. The plant is attacked by a number of insect pests, including the gram pod borer (Helicoverpa armigera), the arhar plume moth (Exelastis atomosa), arhar pod fly (Melanagromyza obtusa), the legume pod borer (Maruca vitrata), the tur pod bug and the blister beetle ( Mylabris spp.).[ citation needed ]
The tur pod bug is the most damaging sap-sucking pest of pigeon pea in India.[ citation needed ] The pods and seeds are the prime site for attack, young seeds being damaged; during heavy attacks the pods become shrivelled. Flowers, leaves and young shoots are additionally attacked.[ citation needed ]
The cowpea is an annual herbaceous legume from the genus Vigna. Due to its tolerance for sandy soil and low rainfall, it is an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name.
The genus Lygus includes over 40 species of plant-feeding insects in the family Miridae. The term lygus bug is used for any member of genus Lygus.
The coffee borer beetle or coffee berry borer is a small beetle native to Africa. It is among the most harmful pests to coffee crops across the world where coffee is cultivated. Spanish common names of the insect include barrenador del café, gorgojo del café, and broca del café.
Archidendron pauciflorum, commonly known as djenkol, jengkol or jering is a species of flowering tree in the pea family, Fabaceae. It is native to Southeast Asia, where the seeds are a popular dish. They are mainly consumed in Thailand, Malaysia, Myanmar, and Indonesia and prepared by frying, boiling, or roasting and are also eaten raw. The beans are mildly toxic due to the presence of djenkolic acid, an amino acid which causes djenkolism. The beans and leaves of the djenkol tree are traditionally used for medicinal purposes such as purifying the blood. To date, djenkol is traded on local markets only.
Maruca vitrata is a pantropical insect pest of leguminous crops like pigeon pea, cowpea, mung bean and soybean. Its common names include the maruca pod borer, bean pod borer, soybean pod borer, mung moth, and the legume pod borer. The species was first described by Johan Christian Fabricius in 1787.
Adisura atkinsoni, the field-bean pod borer, is a moth of the family Noctuidae. The species was first described by Frederic Moore in 1881. It is found in Lesotho, KwaZulu-Natal, Transvaal, Zimbabwe, Mozambique, Zambia, Malawi, Congo, Kenya, Uganda and on Madagascar. It is also present in India, China, Korea, Indonesia (Sumatra), Japan, Sri Lanka, Taiwan, Vietnam and the Himalayan region.
Cryptophlebia ombrodelta, the litchi fruit moth or macadamia nut borer, is a moth of the family Tortricidae. The species was first described by Oswald Bertram Lower in 1898. It is native to India, Sri Lanka, Nepal, Indonesia, China, Taiwan, Vietnam, Thailand, western Malaysia, New Guinea, the Philippines, Japan, Guam, the Caroline Islands, Australia and has been introduced to Hawaii.
Chilo suppressalis, the Asiatic rice borer or striped rice stemborer, is a moth of the family Crambidae. It is a widespread species, known from India, Sri Lanka, China, eastern Asia, Japan, Taiwan, Malaysia to the Pacific.
Orius insidiosus, common name the insidious flower bug, is a species of minute pirate bug, a predatory insect in the order Hemiptera. They are considered beneficial, as they feed on small pest arthropods and their eggs. They are mass-reared for use in the biological control of thrips.
Tessaratomidae is a family of true bugs. It contains about 240 species of large bugs divided into 3 subfamilies and 56 genera.
Scirpophaga incertulas, the yellow stem borer or rice yellow stem borer, is a species of moth of the family Crambidae. It was described by Francis Walker in 1863. It is found in Afghanistan, Nepal, north-eastern India, Sri Lanka, Bangladesh, Myanmar, Vietnam, Thailand, Malaysia, Singapore, Sumatra, Java, Borneo, Sumba, Sulawesi, the Philippines, Taiwan, China and Japan.
Cajanus scarabaeoides is a flowering plant in the genus Cajanus. Of the 32 different species within the genus Cajanus, only one, C. cajan (pigeonpea), is cultivated. Cajanus scarabaeoides is the closest wild relative to C. cajan, and is one of the easiest wild species to cross with pigeonpea cultivars. C. scarabaeoides is found naturally in both temperate and tropical zones around the globe. This species has higher levels of drought tolerance, is found to have greater protein content, and has higher levels of resistance to insect pests compared to cultivated types. These genetic traits can be crossed with C. cajan to improve the crop's productivity. For subsistence farmers, this can reduce economic losses and drastically improve overall crop yield.
The pigeon pea is a perennial legume from the family Fabaceae. Since its domestication in the Indian subcontinent at least 3,500 years ago, its seeds have become a common food in Asia, Africa, and Latin America. It is consumed on a large scale in South Asia and is a major source of protein for the population of the Indian subcontinent. It is the primary accompaniment to rice or roti and has the status of staple food throughout the length and breadth of India.
Dysdercus cingulatus is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so.
Xylosandrus compactus is a species of ambrosia beetle. Common names for this beetle include black twig borer, black coffee borer, black coffee twig borer and tea stem borer. The adult beetle is dark brown or black and inconspicuous; it bores into a twig of a host plant and lays its eggs, and the larvae create further tunnels through the plant tissues. These beetles are agricultural pests that damage the shoots of such crops as coffee, tea, cocoa and avocado.
Rhynocoris longifrons is a species of assassin bug in the family Reduviidae. It is a predator of other insects and is found in Asia. Crops on which it is found feeding on pests include pigeon pea, cardamom and peanuts. The insects are potentially useful in biological control because they are more resistant to pesticides than are the pests they consume.
Pyrilla perpusilla, commonly known as the sugarcane planthopper, is a planthopper in the family Lophopidae. It is native to Asia where it feeds on grasses and other plants and is a major pest of sugarcane.
