Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes and the causal agent of slow decline of citrus. T. semipenetrans is found in most citrus production areas and diverse soil textures worldwide. Their feeding strategy is semi-endoparasitic and has a very narrow host ...
The classification of stunt nematodes - those including the genus Tylenchorhynchus - is unstable; many newly discovered species within this genus are reconsidered to be actually subspecies. [1] Stunt nematodes such as Tylenchorhynchus and the closely related genera, Anguillulina and Merlinia , include more than 250 known species.
Feeding types of plant-parasitic nematodes This article is an attempt to list all agricultural pest nematodes . Species are sorted in alphabetical order of Latin name.
Bacillus firmus I-1582 (Bf I-1582) has proven to be an effective nematicide against nematodes such as Rodopholus similis, Xiphinema index, Heterodera sp., Ditylenchus sp., Tylenchulus semipenetrans and Meloidogyne sp. [7] It is approved as a biological-based nematicide against root-knot nematodes in crops by the European Commission. [8]
Nematode-trapping fungi are mostly concentrated in the upper part of the soil, in pastures, leaf litter, mangroves and certain shallow aquatic habitats. They employ techniques such as adhesive hyphal strands, adhesive knobs, adhesive nets formed from hyphal threads, loops of hyphae which tighten round any ensnared nematodes and non-constricting ...
Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs.
Under the new program, farms with herds that test negative for three consecutive weeks using bulk tank milk samples will be able to move cattle without additional pre-movement testing, USDA said ...
Ostertagia ostertagi, commonly known as the medium stomach worm or brown stomach worm, is a parasitic nematode (round worm) of cattle. O. ostertagi can also be found to a lesser extent in sheep, goats, wild ruminants, and horses. It causes ostertagiosis, which is potentially fatal in cattle.
