Root-knot nematode larva, SEM
Root-knot nematode larva. Coloured scanning electron micrograph (SEM) of the whiplike larva of the root-knot nematode Meloidogyne incognita. Here, it is penetrating a tomato root. Once inside the root, it establishes a feeding site. Growths called galls form, and the larva consumes nutrients, stunting the plants growth

EDITORS COMMENTS
This print showcases the intricate world of root-knot nematode larvae. In this coloured scanning electron micrograph (SEM), we witness the relentless pursuit of a whiplike larva as it penetrates a tomato root, marking the beginning of its parasitic journey. Once inside, this tiny creature establishes a feeding site that triggers the formation of galls, peculiar growths that disrupt normal plant development. The consequences are dire for the tomato plant as these voracious larvae consume vital nutrients, ultimately stunting its growth. This image serves as a powerful reminder of nature's delicate balance and the constant battle between organisms seeking survival and those striving to thrive. With its botanical and zoological significance, this SEM offers valuable insights into both plant pathology and parasitology. The roundworm-like structure is characteristic of Meloidogyne incognita, commonly known as cotton or southern root knot nematode—a notorious plant pest responsible for devastating crop yields worldwide. Through cutting-edge scanning electron microscopy techniques, scientists can delve deep into the hidden realm beneath our feet—unveiling an astonishing world where microscopic parasites like these nematodes play significant roles in shaping ecosystems and impacting agricultural practices. This remarkable photograph from Science Photo Library not only captures scientific curiosity but also highlights the beauty found within even the tiniest organisms that surround us every day.
