The rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae) is a serious, polyphagus, extremely destructive primary pest mainly of rice that infests barley, maize and wheat in storage also worldwide. Its adults are capable of infesting intact grain kernels in the while its grubs feed and complete their development inside grain kernels. Adults prefer to feed endosperm decreasing carbohydrate content. On the other hand, grubs prefer to feed on proteins and vitamins decreasing nutritional value as well as germination capacity. For the management of this insect pest, methyl bromide as well as phosphine has been used as fumigants from past few decades. Inspite of receiving success, the use of these fumigants has been prohibited as these deplete ozone layer. In addition, rice weevils have developed resistance due to its continuous uses. This forced to search new alternatives as eco-friendly safe control systems. In this regard, plant based products like extracts, powders and essential oils have been evaluated and received significant promising results. Biological agents like hymenoptera parasite, predators and entomopathogenic fungi have also been investigated but received little success in this direction. Therefore, combined efforts of different control strategies would be more useful to maximize the protection level from rice weevil infestation.

“…Gamma irradiation (GI) has been approved as a safe method for storing products (Nasr et al 2022 ). Irradiation can be considered a successful method for reducing the prevalence of food-borne diseases and for treating several possible issues in food (Sajjabut et al 2019 ).…”

Bee pollen is a healthy product with a good nutritional profile and therapeutic properties. Its high moisture content, however, promotes the growth of bacteria, molds, and yeast during storage commonly result in product degradation. Therefore, the aim of this study is to assess the effectiveness of gamma irradiation (GI) and ozone (OZ) as bee pollen preservation methods for longer storage time, as well as whether they are influenced by pollen species. To do that, GI at a dosage of 2.5, 5.0, and 7.5 kGy was applied at a rate of 0.68 kGy/h and OZ application at a concentration of 0.01, 0.02, and 0.03 g/m3 was applied for one time for 6 h, to Egyptian clover and maize bee pollen, then stored at ambient temperature for 6 months. We then determined the total phenolic content (TPC) and antioxidant activity of treated and non-treated pollen samples at 0, 3, and 6 months of storage. Total bacteria, mold, and yeast count were also evaluated at 0, 2, 4, and 6 months. Statistical analyses revealed that, TPC, antioxidant, and microbial load of both clover and maize pollen samples were significantly (p < 0.05) affected by both treatment and storage time and their interaction. Both methods were extremely effective at preserving the antioxidant properties of pollen samples after 6 months of storage at room temperature. Furthermore, the highest concentrations of both GI and OZ applications completely protected pollen samples from mold and yeast while decreasing bacterial contamination. GI at the highest dose (7.5 KGy) was found to be more effective than other GI doses and OZ application in preserving biologically active compounds and lowering the microbial count of pollen samples for 6 months. As a result, we advise beekeepers to use GI at this dose for longer-term storage.

Plant mutation breeding plays a pivotal role in increasing plant genetic variability, pest and disease resistance and yield production. Gamma ray irradiation induced to infected plants to obtain resistant mutant plants. This research aims to examine the morphological characterization of pepper plants and the mutant plants produced from irradiated PepYLCV-infecting local pepper from Karo Regency, Sumatra Utara, Indonesia. The research was conducted in January to October 2021 in farming land in Tongkoh Village, Dolat Rayat District, Karo Regency, Sumatra Utara, using non-Factorial Randomized Block Design. The mutation was induced by exposing the seeds of local chili to varied doses (D): 0 (uninfected seeds and unirradiated infected seeds), 150, 200 and 250 Gy and was performed using T-Test, replicated 3 times. The results of research showed that different doses of gamma rays significantly affected the mutant plants from the observation on its plant height, stem diameter, canopy and fruit lengths, fruit weight, number of branches, leaves and fruits. Plant induced with gamma ray 150 Gy found to have the longest canopy and fruit and also demonstrated the highest number of branches, flowers, leaves and the highest fruit weight compared to other higher doses. The exposure of gamma irradiation gave positive effect to infected chili to enhance their resistance in order to produce higher yield.
