In This work, We investigate the investment of entomopathogenic Steinernema nematodes (Rhabditidae) in their symbiotic association with Xenorhabdus bacteria (Enterobacteriaceae). Their life cycle ...

The infectivity, incubation time, and reproduction of three heterorhabditid nematodes, Heterorhabditis sp. Bacardis and FL2122 strains and H. bacteriophora Poinar HP88 strain were studied in two ...

In the Mesorhabditis belari roundworm, the sole purpose of males is to help females produce clones of themselves. In 1949, the young biologist Victor Nigon described the reproduction of various ...

Nematodes go through four larval stages before they mature for reproduction. These stages are designated as larva 1 (L1) to L4 or juvenile 1 (J1) to J4. However, under harsh environmental conditions, ...

The nematode worms that cause the world's most devastating crop losses have given up on sexual reproduction and instead rely on their large, duplicated genomes to thrive in new environments, report ...

Male sex really is important to the survival of the species — at least for the nematode, a lowly worm that can reproduce without masculine help but adapts better if males get into the act. In a study ...

Male sex is important even for the lowly nematode, a soil worm that can reproduce without the masculine gender. A new study shows that keeping guys around may be essential to survival of the species.

As worm mothers age, they secrete a milk-like fluid through their vulva that is consumed by their offspring and supports their growth, according to a new study led by UCL researchers. Scientists say ...

In natural ecosystems, bacterial communities play an important role in nutrient cycling, primary production and decomposition 1. Bacteria are also heavily consumed by bacterivorous nematodes that are ...

This news release is available in German. Pristionchus nematodes come in two varieties: Most species consist of typical males and females, but in several species the females have evolved the ability ...

Is sex overrated? It depends on who you ask. In the case of the asexual root-knot nematode, the answer would probably be "yes". Unlike animals such as the American cockroach and leopard shark, which ...

In 1949, the young biologist Victor Nigon described the reproduction of various species of nematodes, small roundworms that live in the soil in its doctoral thesis. These include Mesorhabditis belari, ...
