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.
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs.
Plum pox, also known as sharka, is the most devastating viral disease of stone fruit from the genus Prunus. The disease is caused by the plum pox virus (PPV), and the different strains may infect a variety of stone fruit species including peaches, apricots, plums, nectarine, almonds, and sweet and tart cherries. Wild and ornamental species of Prunus may also become infected by some strains of the virus.
Muhlenbergia schreberi, the nimblewill, is a grass species in the family Poaceae native to North America.
Paspalum scrobiculatum, commonly called Kodo millet or Koda millet, is an annual grain that is grown primarily in Nepal 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.
Coccinella transversalis, commonly known as the transverse ladybird or transverse lady beetle is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. It is not to be confused with Coccinella transversoguttata, a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together.
Brumoides suturalis, the three-striped lady-beetle, is a species of ladybird described by Johan Christian Fabricius in 1789. It is found in India, Pakistan, Bangladesh, Sri Lanka, Bhutan, Nepal, Indonesia, Philippines and Papua New Guinea. Found on indoor window ledge in Manchester, UK. February 25th 2022. Must have hitchhiked on flowers.
The Chrysanthemum Aphid,, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants.
The sugarcane aphid,, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is mostly found in Saccharum and Sorghum species. The species primarily reproduces via parthenogenesis, although sexual morphs have been discovered in China, Japan, and Mexico - in China the eggs overwinter in the host Miscanthus sacchariflorus.
Pentalonia nigronervosa is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap mainly from Musa species.
Rhopalosiphum rufiabdominale, the rice root aphid or red rice root aphid, is a sap-sucking insect pest with a wide host range and a global distribution. As a member of the superfamily Aphidoidea, it is one of 16 species of the genus Rhopalosiphum. Adults and nymphs are soft-bodied and usually dark green with brown, red, or yellow tones. Like all aphids, reproduction is sexual and asexual, depending on the environmental conditions and host plant. Rice root aphids cause injury to external plant parts, namely the roots or stem, by feeding on plant sap and vector several important plant viruses. The hosts of this pest extend across multiple plant families with most belonging to Rosaceae, Poaceae, and Solanaceae. R. rufiabdominale is universally associated with Prunus species but also infests various field crops, greenhouse vegetables, cannabis, and other ornamental plants. While this aphid originates from east Asia, it spans nearly every continent. Dispersal is particularly widespread across the United States, India, and Australia, with crop damage documented in multiple instances, although economic losses are primarily associated with Japanese rice crops. Nonetheless, it remains a pest of serious concern due to its high mobility, discrete habitat, and adaptive plasticity, giving it the rightful reputation as a successful invader.
The Indian grain aphid, also known as Sitobion (Sitobion) miscanthi, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from cereal plants, making it a pest of wheat production. It has also been recorded as a pest of finger millet, sorghum, and pearl millet in South Asia.
The sugarcane woolly aphid is an aphid in the superfamily Aphidoidea in the order Hemiptera. Found in India and Southeast Asia, tt is a true bug and sucks sap from plants. It is a foliage sucking aphid species.
Anoecia is a genus of aphids typical of the subfamily Anoeciinae.
Pseudaspidimerus trinotatus, is a species of lady beetle found in India, Sri Lanka and Myanmar.
Scymnus (Pullus) latemaculatus, is a species of lady beetle found in Pakistan, India, Bangladesh, Sri Lanka, Thailand, and Taiwan.
Scymnus (Scymnus) nubilus, is a species of lady beetle found in Pakistan, India, Bangladesh, Sri Lanka, Nepal, Myanmar, China, and Asia Minor.
Scymnus (Pullus) coccivora, is a species of lady beetle found in India, Bangladesh, Sri Lanka, Malaysia, and Pakistan and probably in Thailand, Bermuda, British Virgin Islands, Grenada, Saint Kitts and Nevis, Trinidad and Tobago and Papua New Guinea.
