“…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.

“…We firstly compared the developmental durations of N. poppiusi and N. tenuis preying on C. cephalonica eggs, one of the most efficient surrogate hosts for rearing a wide range of biological control agents (Vincent et al 2021, Wang et al 2021, Di et al 2022). The hatching time for N. poppiusi was significantly slower than that for N. tenuis at 25°C in this study, which was similar to the several previous studies (Fauvel et al 1987, Perdikis and Lykouressis 2002, Sanchez et al 2009).…”

Mirid predators are increasingly used in biological control of multiple greenhouse crops pests. However, due to great morphological similarity and tiny body size, some mirid predators have been largely confused with their allied species. Nesidiocoris tenuis Reuter as a commercial mirid predator was confused largely with Nesidiocoris poppiusi Carvalho in China. To evaluate the biocontrol potential of N. poppiusi, its biological traits and the functional response to Bemisia tabaci Gennadius were studied compared with N. tenuis under laboratory conditions. The results showed that no significant differences of the developmental times from the first instar to adult stages between the 2 mirids fed on Corcyra cephalonica Stainton eggs were observed, while N. poppiusi had better population growth parameters than N. tenuis. Under the condition with prey, both female and male of N. poppiusi lived significantly longer than those of N. tenuis. It could lay 74.0 eggs, which was significantly higher than that of N. tenuis (30.2 eggs). Under the condition without prey, both N. poppiusi and N. tenuis couldn't complete development to adulthood on tomato, tobacco, muskmelon, and cabbage leaves, however, tobacco and tomato were more suitable than the other 2 plants. A type II functional response was observed for both males and females of the 2 predators. Nesidiocoris poppiusi females consumed significantly more B. tabaci pupae than N. tenuis when prey densities were large than 30. Our results indicated that N. poppiusi could be a promising candidate for biological control of B. tabaci.

Parasitism research Trichogramma sp. (Hymenoptera: Trichogrammatidae) has been carried out with the aim of studying the functional response of the parasitoid Trichogramma sp. Functional response is one measure to determine the effectiveness of a predator or parasitoid as an agent in biological control, so that it can express a change in the number of preys attacked by individual predators. Temperature is one of the most important host-parasitoid interactions in functional responses. The method used in the parasitoid parasitism Trichogramma sp. on the host Corcyra sp. using four levels of egg density Corcyra sp. with two different temperature treatments (27OC and room temperature). The results show the functional response model of the parasitoid Trichogramma sp. against its host Corcyra sp. described in the type I model. Parasitization level of Trichogramma sp. showed the same results for both temperature treatments, however, it also shows differences in the speed of predation. It also showed linearity between the parasitoids Trichogramma sp. with the host Corcyra sp. Parasitism rates are still increasing, along with an increase in host density. This research can be a starting point to improve the control of Corcyra sp. using the parasitoid Trichogramma sp. in the field.
