The Pest Information Management Systems (PIMS) is an online database of pests and diseases affecting food crops grown and traded across borders. PIMS is the first of its kind in across Africa and has been developed through the support of the East African Trade and Investment Hub (EATHUB), a USAID program.

Arthraxon hispidus (Thunb.) Makino (1912)small carpetgrassKenyawide range of habitats; terrestrial to acquatic, Warm temperate and tropical climate
Avena fatua L. (1753)wild oatKenyaA. fatua is a cosmopolitan grass weed growing on nearly all soil types. The plant tolerates soil pH as low as 4.5 (Holm et al., 1977), but calciphilous subspecies are also found (Korniak, 1985; Hanf, 1990). Growth and viability are not restricted by low temperatures, although A. fatua has its origin in the relatively arid climate of Asia. A. fatua has relatively large seeds, the majority of which fall close to the parent plant. There are no reports of natural dispersal by wind or water, though this must occur to some extent. Movement by animals is similarly not discussed in the literature. The dispersal and spread of A. fatua is closely associated with the cultivation of cereal crops around the world. Movement over longer distances is most likely the result of importation of contaminated grain.
Barley yellow dwarf virusesbarley yellow dwarfKenya They are spread efficiently by several aphid vectors (Rhopalosiphum padi, Sitobion avenae, Metopolophium dirhodum, Rhopalosiphum maidis, Schizaphis graminum among others) that are prevalent worldwide. They are not mechanically or seed transmissible.

Boerhavia diffusa L. (1753)red spiderlingKenyaB. diffusa is a terrestrial, prostrate, perennial herb which grows to 1-1.5 m long. It propagates by root stocks and by seed, although seeds only account for 21% of reproduction. It flowers and fruits throughout the year (Mathur and Bandari, 1983
Cadra cautella Walkerdried currant mothKenyaThe almond moth thrives best in warm, humid environments. The ideal temperature range for development is 30-32 degrees Celsius (86-90 degrees Fahrenheit), and the ideal humidity range is 70-80% plant trade and pathway vectors
Carpophilus Stephens 1829dried-fruit beetlesKenyafound widely throughout the tropical and subtropical regions of the world. They require relatively high moisture levels for successful development. plant parts (true seeds, fruits and roots), land vehicles
Ceratophyllum demersum Linnaeus, 1753coontailKenyaAn invassive weed with a wide ecological tolerance and grows relatively fast. Found in temperate and tropical climates water, animals (Pets and aquarium species), man, land vehicles, plant parts (debris),
Chenopodium album L. 1753fat henKenyaC. album occurs from sea level to altitudes of 3600 m, and from latitudes 70?N to more than 50?S. It is a common weed of almost all cultivated crops, gardens, horticultural crops and orchards. It is also found on wasteland, in pastures and strips of uncultivated land, and along roadsides and riverbanks. It is tolerant of a wide range of cultural conditions, climates, soil types, fertility and pH, a fact reflected in Coquilat's (1951) suggestion that it is one of the five most widely distributed plants in the world. It is most vigorous in fertile, heavy and well-irrigated soils (reaching up to 2 m in height), often remaining as a dwarf in dryer and less fertile soils. Reproduces solely by seed. C. album has no specialized seed dispersal mechanisms, so that the majority of seeds simply fall to the ground around the parent plant. They are not buoyant, but may be transported long distances by water. A percentage of seed also passes unharmed through animals and may be transported in this way (Holm et al., 1977).
