Coloured SEM of grain weevil
Numéro d’image : 11907945
| False-colour scanning electron micrograph (SEM) of the grain weevil Sitophilus granarius emerging from a wheat grain. The weevil is a type of beetle. Its head is elongated into a snout,called a rostrum,which has blade-like mandibles at its tip. The rostrum bores through the fibrous coat of a wheat grain & the mandibles chew & crush the kernel. Female weevils insert their eggs in cavit- ies dug in the kernel,ensuring a food supply for the larvae. Stored grain is vulnerable to infestations,although the use of fumigants and improved storage methods has reduced the risk. Mag: x6 at 35mm size,x12 at 6x7cm size.
