The widespread use of such programmes may lead to the selection of drug-resistant strains of gastrointestinal nematodes.
The location of these nematodes perhaps provides circumstantial evidence for the occurrence of vertical transmission.
Cuticular detachment is likely to influence the physiology of the nematodes, including development of eggs and juveniles.
In the lowland rice experiment (2) no differences in nematode population densities were recorded between treatments, although densities were relatively low over both years.
Man between 1995 and 1997, may account for some of the differences in nematode densities between treatments between seasons during this period.
This result implies that rather complex mechanisms might be involved for cover crops or soil amendments in controlling plant-parasitic nematodes, which definitely need further investigation.
The three selected species of fungi produce three-dimensional adhesive nets in the presence of nematodes.
