Grain weevil Z330 / 0408
Grain weevil. Coloured scanning electron micrograph of a grain weevil (Sitophilus granarius). This beetle infests and damages stored grain, using the mandibles at the end of its elongated snout, or rostrum, to cut through the shell of a wheat grain and gain access to the food within. Females lay their eggs inside wheat grains, in order that their larvae can have a food supply. It can be controlled using fumigants. Magnification: x33 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate details of a grain weevil, known as Sitophilus granarius. The coloured scanning electron micrograph reveals the fascinating features of this tiny beetle that infests and damages stored grains. With its elongated snout or rostrum, the grain weevil uses its mandibles to cut through the shell of wheat grains, gaining access to the nourishing food inside. This destructive behavior is further exacerbated by females who lay their eggs within wheat grains, ensuring a constant supply of food for their larvae. The image highlights the importance of controlling these pests using fumigants in order to safeguard stored crops from spoilage. At a magnification of x33 when printed 10 centimeters wide, every minute detail becomes apparent - from the structure and function of its mandibles to its distinctive body shape. This photograph not only offers insight into the biology and behavior of this particular species but also serves as a reminder of how crucial it is to protect our valuable food resources from such invasive insects. As an invaluable tool in zoological research and pest control strategies, scanning electron microscopy allows us to appreciate both the beauty and intricacy found within even some of nature's smallest creatures.
