Three concentrations of nematodes
(103, 104, and 105 IJ/mL) were prepared according to methods of Kaya & Stock (1997).
After the first description of Onchocerca lupi nematodes
in 1967 in a Caucasian wolf (Canis lupis cubanensis) from Georgia (former Union of Soviet Socialist Republics), this nematode
has been recognized as the causative agent of canine and feline onchocercosis (3,4).
The fact that nematodes
are virtually impossible to eliminate will, for better or for worse, help to naturally maintain a healthy market for nematicide manufacturers.
In a preliminary study, the plant-parasitic nematodes
root-knot (Meloidogyne javanica), citrus (Tylenchulus semipenetrans), root-lesion (Pratylenchus spp.
are known to respond directionally to various cues, including electrical stimuli.
Integrated solutions are key to effective nematode
are natural organisms that prey on garden pests and are already present in our soil.
The resistant wheat, however, serves as a trap crop to trick the nematodes
into starting their life cycle but then prevents them from reproducing, according to researchers at the University of California.
Because of this problem, we looked for a method that does not require the use of higher animals, and decided to test whether nematodes
could be used for ricin detection.
But when the researchers looked at a variety of nematodes
, they found the very same types of chemicals being combined and used for communication, said Paul Sternberg, the Thomas Hunt Morgan Professor of Biology at Caltech and senior author on the study.
are an incredibly diverse group encompassing numerous intestinal parasites and the widely studied laboratory roundworm C.
Tactics for management of plant-parasitic nematodes
continue to rely on nematicides for suppression of population densities.
