“…Among harmful species, the case of the rice moth Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae) has caught the attention of the scientific community. In fact, despite its common name associated with rice cultivations, several studies have discussed the ability of C. cephalonica populations to infest other products including corn, sorghum, cocoa, almond, beans and dried fruit (Hashem et al, 2018).…”

The rice moth Corcyra cephalonica is a harmful insect pest for grains stocked in storage systems. Its infestations represent a serious concern among producers, because of the non-marketability of the products affected by it and subsequent economic losses. New technologies are improving the supply chain of the stored grains, in line with the integrated pest management framework. However, a prompt control action also requires an in-depth knowledge of insect pests' biology and their response to environmental parameters. If this information is available, it can also be translated into mathematical language. The modelling of insect pest populations is increasing in utility, particularly if the models are included in decision support systems. The aim of this work concerns two aspects of a model application and validation. Since physiologically based models require information about interactions between species and environment, C. cephalonica individuals were reared at different constant temperatures: 18, 21, 24, 26, 28, 30, 34 and 36 °. This first part provided the life tables, whose data were used to estimate the parameters of the Logan, Briére, and Sharpe and De Michele development rate functions. The second part of the work concerns the application of a physiologically based model described by a first order partial differential equation. The validation of the simulations was conducted with a semi-field experimentation with three repetitions. Results showed that the life tables are well represented by the Sharpe and De Michele development rate function, and that the physiologically based model proposed is reliable in representing field populations.

Medicinal and spices plants are crucial, and they can become infested by several insects, such as drugstore beetle (Stegobium paniceum l.) and the cigarette beetle (Lasioderma serricorne), during storage. Therefore, the present study aimed to assess the effect of enriched modified atmospheres (MAs), with CO2 or N2, on L. serricorne and S. paniceum adults and larvae and their effect on quality of chamomile flowers and coriander seeds during storage. Various carbon dioxide and nitrogen gas concentrations were tested, including 40% CO2, 50% CO2, 60% CO2, 97% N2, and 98% N2. The larval mortality for S. paniceum reached 100% after 6 days of 60% CO2 and 8 days for the L. serricorne. At 98% N2 treatment, the complete mortality (100%) of S. paniceum and L. serricorne adults was recorded following 3 and 9 day exposures and of larvae following 10 day exposure.The quality parameters (weight loss percentage, germination, essential oil percentage, and color) of chamomile flower and coriander seeds treated with 60% CO2 and control were studied after 3 and 6 months of storage. The MAs had the lowest weight loss percentage, the highest lightness value, the lowest color changes, and the highest essential oil content of chamomile flower and coriander seeds compared with the control treatment. Additionally, the MAs induced a higher germination percentage of coriander seeds compared with the control. Treatment with CO2 increased some essential oils compounds, compared with control after 6 months of storage of chamomile. All compounds were decreased in coriander seeds treated with CO2, except for carvone and anethole, which were increased. In conclusion, our study recommends using MAs to control S. paniceum and L. serricorne during storage and maintain the quality of chamomile flower and coriander seed.
