Introgression of ivermectin resistance genes into a susceptible Haemonchus contortus strain by multiple backcrossing [PDF]

, 2012
Anthelmintic drug resistance in livestock parasites is already widespread and in recent years there has been an increasing level of anthelmintic drug selection pressure applied to parasitic nematode populations in humans leading to concerns regarding the

The consequences of host heterogeneity for parasite transmission depend on how host infectiousness is determined

Journal of Animal Ecology, EarlyView.
This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...

Rhizosphere Microbiomes Modulated by Pre-crops Assisted Plants in Defense Against Plant-Parasitic Nematodes

Frontiers in Microbiology, 2018
Plant-parasitic nematodes cause considerable damage to crop plants. The rhizosphere microbiome can affect invasion and reproductive success of plant-parasitic nematodes, thus affecting plant damage.

Diversity of Xenorhabdus and Photorhabdus spp. and their symbiotic entomopathogenic nematodes from Thailand [PDF]

, 2012
Xenorhabdus and Photorhabdus spp. are bacterial symbionts of entomopathogenic nematodes (EPNs). In this study, we isolated and characterized Xenorhabdus and Photorhabdus spp.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Nematode survival in relation to soil moisture [PDF]

, 1973
Established nematode populations are very persistent in the soil. It is known that they need sufficient soil moisture for movement, feeding and reproduction (fig. 5), and that there are adverse soil moisture conditions which they cannot survive.

Anthelmintic resistance in sheep nematodes in Australia: a compilation of recent test results

Australian Veterinary Journal, EarlyView.
Objective The results of recent faecal egg count reduction tests (FECRTs) were collated to provide an indication of the prevalence and severity of anthelmintic resistance in sheep nematodes across Australia and of changes in comparison to earlier testing reports.

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Nematode Management in Okra

EDIS, 2002
Plant-parasitic nematodes are small, microscopic roundworms that live in the soil and attack the roots of plants. Crop production problems induced by nematodes therefore generally occur as a result of root dysfunction; nematodes reduce rooting volume ...

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.
