Abstract:
This study was conducted in the El-Goléa region from November 2023 to March 2024
with the aim of inventorying stored food pests. We selected three study stations: the
Mahmoud Hadjedj farm, containing dates, the CCLS El-Goléa station, containing cereals and
dried vegetables, and a point-of-sale station, also containing cereals. and bagged
vegetables. Samples were taken randomly, and the insect pests were identified in the
laboratory after incubation using determination keys. We observed the presence of a single
pest for rice (Rhyzopertha dominica), with an infestation rate of 58.3%. Similarly for beans
(Bruchus rufimanus), the infestation rate was 66.67%. The weight of the beans, varied
between 0.81g and 3.06g, but this variation had no effect on the infestation rate. Regarding
the infestation rate of dates, it was approximately 57%. Biometric measurements of dates
showed lengths between 32.0mm and 45.6mm, widths, between 12.8mm and 21.6mm, and
weights between 3.1g and 5.8g. These measurements did not affect the infestation of dates
by the moth (Ectomyelois ceratoniae). Similarly, no reported between these biometric
measurements and the infestation rate of dates by Boufaroua (Oligonychus afrasiaticus).
