“…The maximum fecundity of 239.16 eggs/ female was recorded on maize (48.5%)+ sorghum (48.5%)+ groundnut (3%) diet and minimum fecundity 180.67 eggs/ female was found on wheat (100%). The current findings are in close agreement with those of Jhala et al (2019) and Bhandari and Regmi (2014) and Patel (2011). Lowest growth index (1.39) was recorded on wheat (100%) diet and significantly highest (2.66) on maize (48.5%) + sorghum (48.5%)+ groundnut (3%) diet (Table 1).…”

The influence of various diets was evaluated on the biology of Corcyra cephalonica (Stainton) under laboratory conditions. Results revealed that the lowest egg hatching (60.33%) was found on wheat diet 100% and highest (87.50 %) was on bajra (32.33%) + maize (32.33%) + wheat (32.33%) + sugar (3%) diet.The shortest and longest incubation period (3.83 and 6.67 days), larval period (31.83 and 40.67 days) and total developmental period (50.50 and 65.00 days) were recorded on bajra (100%) and wheat (100%) diet, respectively. Meanwhile shortest and longest pupal period (14.83 and 19.33 days) were recorded on bajra (100%) and maize (100%) diet, respectively. The maximum and minimum adult emergence (88.33 and 53.75 %), sex ratio (1.72:1 and 0.42:1), adult male lifespan (12.50 and 7.17 days), fecundity (239.16 and 180.67 eggs/ female) and growth index (2.66 and 1.39) were recorded on maize (48.5%) + sorghum (48.5%) + Groundnut (3%) diet and Wheat (100%) diet, respectively. Life span of adult female was longest (8.67 days) and shortest (4.67 days) on diet maize (48.5%) + sorghum (48.5%) + groundnut (3%) and bajra (100%) diet, respectively. It may be concluded that among the seven diets, the most preferred diet for rearing of C. cephalonica was maize (48.5%) + sorghum (48.5%) + groundnut (3%) and the least preferred diet was wheat (100%).

“…Although there were no reports to date indicating either of the insect species identified in stored sesame seeds in Ethiopia, our current findings were consistent with earlier research that suggested that C. cephalonica was noted as a significant sesame storage pest in India (Babu et al 2020;Dilipsundar et al 2019). Similar to this, C. cephalonica was also identified as a significant insect pest of many stored products in the tropics, affecting a variety of commodities, including oil seeds like groundnuts, cotton seeds, flax seeds, and oil-cakes (Bhandari et al 2014;Debbarma et al 2021;Vincent et al 2021). Typically, the destructive larval stage of C. cephalonica prefers to infest cracked or damaged grains, where it feeds beneath the formed silken threads, which over time gather density and bulk up the contaminated items (Chaudhuri and Senapati 2017).…”

Insufficient storage practices and frequent infestations of insect pests pose significant obstacles to sesame production and storage, adversely affecting the quality and quantity of seeds. This forces farmers and traders to sell their crops at lower prices immediately after threshing to avoid market rejection caused by pests and mold damage during storage. The objective of this study was to investigate the insect species dynamics and the losses of on-farm-stored sesame seeds during the 2017- 2018 production year. Sesame seed samples obtained from randomly selected 431farm households in five districts were analyzed to determine the insect species present, insect density, seed weight loss, seed damage, germination percentage, and dockage using R software version 4.2.2. Biophysical parameters such as inter-granular temperature, seed moisture, and relative humidity were also recorded. Furthermore, interviews were conducted with the 431 farm households to gather information on their seed storage methods, practices for controlling insect pests, and the varieties of sesame they produce and store. The findings revealed the presence of 13 arthropod species from four orders (Coleoptera, Hemiptera, Hymenoptera, and Lepidoptera) which belongs to eight families (Tenebrionidae, Silvanidae, Bostrichidae, Curculionidae, Carabidae, Coreidae, Formicidae, and Pyralidae) in the stored sesame seeds at the study site. The most prevalent species was the flour beetle (Tribolium spp.), accounting for 44.26% of the infestation, followed by the rice moth, lesser grain borer, and rice weevil, which constituted 28.2%, 15.72%, and 4.88% of the infestation, respectively. The farmers grew and stored nine different cultivars along with one improved sesame variety called setit-1. On average, there was a 1.97% loss in seed weight, with insect pests causing damage to 8.3% of the seeds. The study districts exhibited an average of 3.79 insects per kilogram of sesame seeds, and the seeds showed a mean germination rate of 77%, which was significantly influenced by the extent of insect damage. The study underscores the significant challenges faced by sesame production and storage in Ethiopia due to inadequate storage practices and infestation by insect pests, resulting in diminished seed quality and quantity. To mitigate the losses incurred from storing sesame on farms, effective measures should be implemented, including improved storage practices and efficient pest control methods.

“…Moreover, the knowledge of the population trends, on the basis of the thermal conditions in the storage system, can be helpful for the management of alternative control methods, such as the use of natural enemies. Natural control methods can be offered by insect enemies belonging to the genera Trichogramma and Bracon (Bhandari et al, 2014). These valuable candidates may be involved in a biological control program, but one of the major difficulties is that their efficiency as pest management tools strongly depends on the time of release.…”

“…This is possible because the application of the model (1) provides for the estimation of the development rate functions parameters, which is made possible only using life tables data. Hence, once a valuable candidate is chosen among those proposed by Bhandari et al (2014) or Nasr et al (2015), a series of constant temperature rearing would enable their development rate function parameters to be estimated.…”

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.
