Identification of insect contaminants of food by the micromor-pholooy of the insect fragments

The identification of insect fragments showed that the infestation was done, mainly, by Coleoptera of the genus Sitophilus Sch›nherr, 1838 (Curculionidae) and Rhizoperthadominica (Fabricius, 1792) (Bostrychidae), that are caracteristic of internai infestation, and in lesser percentage by insects charac-teristic of externai infestation, as Crylolestes spp. (Cucujidae), Tribolium spp. (Tene-brionidae), Oryzaephilussurinamensis(Linnacus, 1758) (Cucujidae) and Lasioderma serricorne (Fabricius, 1792) (Anobiidae). From the total of recovered and identified insect fragments, 59% were fragments of elytra, 23% of mandibles, and in minor percentage by tarsal segments, claws, tibial spurs, legs, tarsus, eyes, antennae, exuviae and larvae urogomphi.
