The lesser grain borer is a cosmopolitan insect, but it survives best in tropical climates where it attacks cereals as well as milo and sorghum.... The lesser grain borer is a much more ferocious feeder than weevils and what they do not eat they spoil. The female lays about 300 to 400 eggs and the larvae feed on the kernel remains left by their parents. At 34 degrees C, it takes 25 days for a complete life cycle. The lesser grain borer is a small brown insect with a cylindrical form, about 3 millimetres long. Looking at the insect from the top, its head is completely hidden by the thorax, which forms a hood-like cover. Pronounced knobs protrude from the thorax.

OBS

A parasite of stored grains.

Le petit perceur des céréales est un insecte cosmopolite, qui prolifère toutefois essentiellement dans les régions tropicales où il attaque les céréales ainsi que le mil et le sorgho. [...] Le petit perceur des céréales est beaucoup plus vorace que les charançons; de plus, il gaspille une plus grande partie des céréales qu'il attaque. La femelle pond environ de trois cents à quatre cents œufs, et les larves se nourrissent des reliefs laissés par les adultes. À 34 degrés C, il faut vingt-cinq jours à l'insecte pour compléter son cycle évolutif. Le petit perceur des céréales est un insecte de couleur brune, de forme cylindrique, qui mesure 3,0 mm de longueur. Vue de haut, sa tête demeure entièrement cachée par le thorax qui l'encapuchonne et dont la surface dorsale, très bombée, forme de petites dents analogues à celles d'une râpe.

OBS

Parasite des grains entreposés.

Bacterial leaf stripe(Pseudomonas syringae subsp. andropogonis) is widely distributed and destructive on many types of sorghums(grain, forage, and sweet or sorgo), sudangrass, and broomcorn as well as on several other related grasses. Long, narrow stripes(1/4 inch by 9 inches or more) form on the leaves. These stripes are initially water-soaked, irregular, and bounded by veins. These areas soon dry and turn brick red, dark purplish red, reddish brown, or tan-to-dark brown depending on the sorghum variety. The color is continuous throughout the lesion. Later, the stripes elongate and fuse to form irregular blotches that cover a large part of the leaf surface and extend into the leaf sheath. Stalks and floral structures may show similar but more restricted lesions.

OBS

Raies bactériennes, Pseudomonas andropogonis. Les premiers symptômes sont de petites (1 cm) taches linéaires entre les nervures. Les taches sur les feuilles et la gaine sont de couleur pourpre, rouge, jaune ou brune, en fonction de la réaction de l'hôte. Si les conditions sont favorables, les taches peuvent dépasser une longueur de 20 cm. On observe de l'exsudat bactérien sur les feuilles infectées.
