Near the body wall but under the epidermal cells are muscle cells; they run in the longitudinal ...Abstract. Root-knot nematodes are severe pests that affect a wide variety of crops. These nematodes are controlled by various types of nematicides that have hazardous effects on the environment. Hence, identification of new approaches alternate to harmful chemical nematicides could be effective in controlling root knot nematodes.

Basal cell carcinoma on the scalp can appear as: Red raised patches that might be itchy. Flat and firm, flesh-colored lesions that appear similar to a scar. Sores that bleed, scab, and either don't heal or heal and return regularly. Small, pink, or red pearly bumps that might have blue, brown, or black areas.Cutaneous larva migrans is a pruritic dermatitis due to the inoculation of helminths larvae in the skin, and it often occurs in children in tropical and subtropical areas. The authors describe an atypical case of cutaneous larva migrans in a 11 year-old child with scalp involvement, an unusual topography for this lesion.

Nematode as pests of important crops. Tylenchida and Dorylaimida are the only two that contain plant parasites among the 17 orders of nematodes (Wyss Citation 1982).More than 4,100 species of plant-parasitic nematodes have been identified between these two orders (Decraemer & Hunt Citation 2006), and new species are continually being discovered (Nicol Citation 2002).

Plant-parasitic nematodes range from 250 um to 12 mm in length, averaging 1 mm, to about 15-35 um in width.Filariasis is spread from host -to-host via the bites of certain flies and mosquitoes that act as vectors for the parasites. For example the filarial nematode Onchocerca volvulus enters the skin from the bite of an infected blackfly (Simulium species). The nematode is in its third larval stage before it moults to its fourth larval stage in 4-6 ...Nematodes are difficult vectors to deal with experimentally because of their small size and their rather critical requirements with respect to soil moisture content, type of soil, and, to a lesser extent, temperature. To overcome these problems, five criteria have been proposed for establishing the nematode vectoring of viruses (Brown et al., 1989; Trudgill et al., 1983).

Root-knot nematodes cause characteristic galls on roots; galls may be up to 1 inch in diameter, but are usually smaller. These galls interfere with the flow of water and nutrients to the plant; infected plants appear less vigorous than healthy plants, may be yellowed, are prone to wilt in hot weather, and respond poorly to fertilizer.Hair worms are long and thin—2 to 118 inches (5 to 300 centimeters) long and 0.02 to 0.4 inch (0.5 to 10 millimeters) wide. They are black, brown, yellow, white, or gray. The front end of most of these worms has a white tip with a thin dark band behind it. Some hair worms have raised bumps on their surface. Most nematodes look similar to each other: slender tubes, tapered at each end (Figure \(\PageIndex{3}\)). Nematodes are pseudocoelomates and have a complete digestive system with a distinct mouth and anus. The nematode body is encased in a cuticle, a flexible but tough exoskeleton, or external skeleton, which offers protection and support.Nematoda is the phylum of the Kingdom Animalia that includes roundworms.
