In general, these nematodes are available in medium to high value markets. Considerable efforts and resources were used in the development of nematode efficacy against corn rootworm, root maggots, and wireworms. These insects are considered the true soil insects, and they are the key target for nematode entry into the agricultural market. Failure of the nematodes to achieve successful and predictable results against these insects have significantly reduced their market potential in this market segment. Against white grubs in turfgrass, nematode performance is inconsistent and expensive compared to standard insecticides.
Cockroaches are the most susceptible insect to the nematodes.
However, failure to develop a nematode-bait station with more than a twelve month shelf life has shattered its commercial introduction. There are many species in the soil that have yet to be discovered. Improving temperature and desiccation tolerance of current formulations through genetic engineering. Introducing nematodes into IPM programs. Baculoviruses Baculoviruses are ingested by the insect larvae causing infection of the insect's cells and its death occurs in 3 to 8 days, depending on the larval species and instar.
