Maize (<i>Zea mays</i> L.) is a significant food security crop in Kenya and it serves as the main source of nutrition and calories among the small-holder farmers. The overall maize yields per hectare have been fluctuating in the past few years posing a great risk to food security. Among the stress factors associated with maize yield loss include plant-feeding nematodes. In this regard, this ...

The filariae are thread-like parasitic nematodes (roundworms) that are transmitted by arthropod vectors. The adult worms inhabit specific tissues where they mate and produce microfilariae, the characteristic tiny, thread-like larvae. The microfilariae infect vector arthropods, in which they mature to infective larvae.Quantitative taxonomic compositions of nematode communities help to assess soil environments due to their rich abundance and various feeding habitats.
