Ascariasis is the infection of Ascaris lumbricoides. Ascaris lumbricoides is the human form of the parasite‚ while ascaris suum is the pig form. Ascaris lumbricoides are the most common worm infection found in humans‚ this is because with 200‚000 eggs that are being made and excreted each day‚ that the chances of infection are exponential. Ascariasis is also known as the Giant roundworm. The Giant roundworm can grow up to 35 cm or 13.7795 inches. This worm may not seem very harmful but the cycle

the smallest known nematode. There are three different types of ecological life cycles of the nematodes. The cycles are called urban‚ sylvatic‚ and marine cycles. The trichinella species is found worldwide. They are prevalent in Mexico‚ the northern hemisphere‚ parts of South Asia‚ Africa‚ South America‚ and Middle East. In the urban cycle the nematodes are carried by pigs and rats. In the sylvatic cycle they are hosted by walruses‚ wales‚ and polar bears. The male’s nematode is 1.4 mm in length

It is preferred to cowpeas and crotalaria‚ for its ability self-reseed along with good disease‚ insect and nematode resistance (Norris and Lawrence‚ 1962). Hairy indigo is currently listed by IFAS as a recommended cover crop with the following agronomic information. Hairy Indigo can produce 15-22 Mg ha-1 forage and 90-170 kg ha-1 nitrogen.
