Abstract The oriental armyworm, Mythimna separata (Walker) is a serious pest of agriculture that does particular damage to Gramineae crops in Asia, Europe, and Oceania. Metamorphosis is a key developmental stage in insects, although the genes underlying the metamorphic transition in M. separata remain largely unknown. Here, we sequenced the transcriptomes of five stages; mature larvae (ML), wandering (W), and pupation (1, 5, and 10 days after pupation, designated P1, P5, and P10) to identify transition-associated genes. Four libraries were generated, with 22,884, 23,534, 26,643, and 33,238 differentially expressed genes (DEGs) for the ML-vs-W, W-vs-P1, P1-vs-P5, and P5-vs-P10, respectively. Gene ontology enrichment analysis of DEGs showed that genes regulating the biosynthesis of the membrane and integral components of the membrane, which includes the cuticular protein (CP), 20-hydroxyecdysone (20E), and juvenile hormone (JH) biosynthesis, were enriched. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated that DEGs were enriched in the metabolic pathways. Of these DEGs, thirty CP, seventeen 20E, and seven JH genes were differentially expressed across the developmental stages. For transcriptome validation, ten CP, 20E, and JH-related genes were selected and verified by real-time PCR quantitative. Collectively, our results provided a basis for further studies of the molecular mechanism of metamorphosis in M. separata.

Wild food plants play an important role in the diet of inhabitants of Oyam District. Some of these plants are drought -resistant and gathered throughout the year . These wild foods are an important source of nutrients. However, there is a lack of comprehensive data re garding the nutrient content s of these indigenous plants. The purpose of this study was to document and assess the nutrient and mineral content s of the selected food plants. Ethnobotanical surveys were used to collect data through formal and informal inter views and focused group discussions. Voucher specimens were collected during field excursions and taken to Makerere Herbarium for proper identification . Nutrients and mineral analyses of wild and cultivated fruits, seeds, underground organs and vegetables from Ngai and Otwal sub counties were carried out using known procedures. They were analysed for mineral nutrients such as calcium, iron, potassium, and phosphorus concentrations. Additionally nutrients such proteins, beta carotene, vitamin C and dietary fibre were determined . On average, vegetables were found to be richer in organic nutrients and minerals followed by fruits and seeds in that order . Generally the wild food plant species were found to be richer sources of mineral nutrient than their cultivated relatives. F or example , the highest concentration of calcium 867.59 mg/100g was found in Acalypha bipartita leaves compared to 294.18 mg/100g in Cleome gynandra . Plant species that showed high iron contents [>30% ] were leaves of swamp hibiscus , African spider flowers , fruits of Tamarind , Black night shade and Jews mallow . It was also noted that among the food plant species analysed, fruits were low in nutrients and mineral elements. Some of these food plants were also considered to have medicinal properties by the locals such as African spider flower, Rattle pod among others. However, it should be noted that there is a general decline in the consumption of wild plants , despite the apparent high nutritional values . T he conservation of wild food plants is not taking place among the communities in the study area, thus the poor rural communities who are limited on balancing their diet could be faced with diseases associated with nutrient deficiencies .
