“…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).…”

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.

“…Consequently, N. tenuis is considered a pest of heated greenhouse tomatoes in Northern Europe [ 45 ]. Nesidiocoris tenuis can also cause damage in open-field sesame and tobacco crops and is considered a pest [ 46 , 47 ]. Our cage studies and many other greenhouse studies showed that confining N. tenuis forces the mirid to rely on tomato plants for survival.…”

The silverleaf whitefly (Bemisia tabaci) and the South America tomato pinworm (Tuta absoluta) are two of the most destructive pests of tomato. Open-field tomato production frequently relies on chemical treatments, which has been shown to lead to pesticide resistance. The integration of biological control using predatory mirid bugs is an effective alternative method for managing these pests. However, methods to establish and maintain populations of zoophytophagous mirids are not adequately described. We explored the potential use of two mirids naturally occurring in Florida, Nesidiocoris tenuis and Macrolophus praeclarus. We conducted 6 field experiments over 4 consecutive years to develop a strategy to maintain the mirids. Pre-plant inoculation of tomato plants did not lead to their establishment, likely due to the low prevalence of prey. We explored the use of sesame (Sesamum indicum) to retain the mirids. Intercropping sesame maintained the populations of N. tenuis throughout the duration of the crop. Macrolophus praeclarus never established in any of the open-field experiments. Nesidiocoris tenuis damage was minimal (<1 necrotic ring/plant) and mirid damage was reduced in the presence of sesame. Our results show that intercropping sesame may provide a means to utilize mirids to manage B. tabaci, an established pest, and provide options to tomato growers should T. absoluta invade USA.

“…Sesame has been attacked worldwide by more than 200 insect pest species belonging to 55 genera (Dilipsundar et al, 2019). Of those, India has reported 55 species of arthropods (Thangjam & Vastrad, 2018), Bangladesh 29 insect pests (Biswas et al, 2001), Uganda 38 insect pests (Ssekabembe et al, 2006), and Nigeria 16 insect pests (Zakka et al, 2018), were identified as pests species of sesame.…”

Sesame is Ethiopia’s most significant oil crop, especially Tigray, Amhara, and some lowland Oromia, Somalia, and the Gambella region. Consequently, the crop is exposed to a wide range of insect pests feeding on leaves, flowers, pods, and seeds affecting sesame yields. This article review provides information on the biology, nature of the damage, and management methods of economically important sesame pests. Sesame webworm, Antigastra catalaunalis (Duponchel) is the most common and frequently encountered pre-harvest pest of sesame. Sesame seed bugs, Elasmolmus sordidus (Fabricus) is also the most serious under field and storage conditions. Gall fly, Asphondylia sesami (Felt) could become a severe insect issue because of sesame gall formation, and Indian meal moth, Plodia interpunctella (Hubner) is a critical stored pest and a significant challenging of crop sesame in Ethiopia. Reports on minor pests are also listed. This paper summarizes current knowledge on pest management strategies, including cultural, biological, and botanical methods, and pesticide applications. The information gathered here indicates that the bioecology, host range, host plant resistance, the occurrence of insecticide resistance, and the development of integrated pest management methods for economical insect pests need to be addressed.
