The development, survival, and fecundity data of Conogethes punctiferalis (Guenée) (Lepidoptera: Crambidae) reared on chestnut (Castanea mollissima Blume), maize (Zea mays L.), sunflower (Helianthus annuus L.), hawthorn (Crataegus pinnatifida Bunge), and apple (Malus domestica Miller) were collected at 25 ± 1°C and 70 ± 5% RH. Raw data were analyzed and compared by using the age-stage, two-sex life table. The mean fecundity (F) was the highest (282.3 eggs per female) when larvae were reared on chestnut. The lowest mean fecundity (19.2 eggs per female) occurred on apple. The net reproductive rates (R0) were 134.52, 106.77, 30.29, 27.61, and 8.63 offspring on chestnut, maize, sunflower, hawthorn, and apple, respectively. The intrinsic rates of increase (r) were 0.1359, 0.1326, 0.0807, 0.0811, and 0.0448 d-1 on chestnut, maize, sunflower, hawthorn, and apple, respectively. Computer projections based on the age-stage, two-sex life table revealed the stage structure and variability of the population growth of C. punctiferalis. Our results demonstrated that although chestnut and maize were the most suitable host plants for C. punctiferalis, the moths were also able to develop and reproduce on sunflower, hawthorn, and apple.

Article Synopsis
- Pre-gelatinized starch is modified starch that can swell in cold water and has diverse industrial applications; this study evaluates high-pressure homogenization (HPH) as a method to produce it from various sources.
- Eleven types of starch were processed through HPH, resulting in altered physical properties such as disrupted surface structures, improved water absorption, and changes in crystallinity and gelatinization temperatures.
- The study found that waxy rice yielded the highest pre-gelatinization and water absorption, while cassava showed the greatest viscosity, suggesting HPH is an effective technique for enhancing the functional properties of pre-gelatinized starches.

Slavonia is the most developed agricultural region in Croatia. With rich and fertile soils that have enabled the cultivation of a wide variety of fruits, vegetables, and cereals, Slavonia has always met the food needs of its population. Today, the biocultural diversity of local varieties and semi-natural vegetation has irretrievably disappeared.

Chinese Xiaokeng green tea (XKGT) possesses elegant and fascinating aroma characteristics, but its key odorants are still unknown. In this study, 124 volatile compounds in the XKGT infusion were identified by headspace-solid phase microextraction (HS-SPME), stir bar sorptive extraction (SBSE), and solvent extraction-solid phase extraction (SE-SPE) combined with gas chromatography-mass spectrometry (GC-MS). Comparing these three pretreatments, we found HS-SPME was more efficient for headspace compounds while SE-SPE was more efficient for volatiles with higher boiling points.

This experiment aimed to investigate the impact of malic acid (MA) and citric acid (CA) on the nutritional composition, fermentation quality, rumen degradation rate, and microbial diversity of a mixture of apple pomace and corn protein powder during ensiling. The experiment used apple pomace and corn protein powder as raw materials, with four groups: control group (CON), malic acid treatment group (MA, 10 g/kg), citric acid treatment group (CA, 10 g/kg), and citric acid + malic acid treatment group (MA, 10 g/kg + CA, 10 g/kg). Each group has 3 replicates, with 2 repetitions in parallel, subjected to mixed ensiling for 60 days.

Since the human population is continuously growing, sufficient food with low environmental impact is required. Especially, the challenge of providing proteins will deepen and insects can contribute to a more sustainable and efficient source of protein for human consumption. larvae are highly nutritious and rearing mealworms is more environmentally friendly compared to the production of traditional livestock meat.
