The Brown marmorated stink bug (BMSB) [Halyomorpha halys (Hemiptera: Pentatomidae)] is a polyphagous pest causing significant damage to approximately 300 crops, such as  nuts, vegetables, and ornamentals. In 2017, the BMSB was discovered for the first time in Türkiye. There is currently no published data available on the biology of the pest in Türkiye.  This preliminary study was carried out in Sakarya province, where the BMSB has observed a low population since 2021. In this study, some biological parameters such as voltinism, mortality rates, egg hatching rates, and egg-adult developmental times of the 1st and 2nd generations of the insect populations were determined. The study was carried out under semi-field conditions and laboratory. Considering the BMSB's minimum temperature threshold, which has yet to be determined in Turkey, the accumulation of degree days was calculated using the references to four possible thresholds (DD12, 12.5, 13, 13.5) and was determined to be between 536.91 - 608.69 DD.  The average egg-adult developmental time was 47.85 days for the 1st generation at naturally fluctuating temperatures and 47.13 days for the 2nd generation under laboratory conditions at 25 ֯C. The hatching rate of egg masses was determined to 90.63% in the 1st generation and 57.75% in the 2nd generation. Total mortality in the first generation was 22.97% and 90.24% in the second generation.  It was revealed  that the insect could produce two generations in Türkiye, but the number of egg-producing adults and eggs laid in the second generation was significantly lower than that in the first. This preliminary study was carried out with a limited number of samples due to the initial infesting in the region and,  therefore more comprehensive research is needed to reveal the the biology of BMSB in the country.

An experiment was conducted during Kharif-1 of 2022 at Bangladesh Institute of Nuclear Agriculture (BINA), Substation, Satkhira to know the effect of foliar application of micronutrients (zinc and boron) on the growth and yield of mungbean. There were three levels of zinc (Zn) (0.2%, 0.4%, 0.6%) and boron (B) (0.2%, 0.4%, 0.6%) along with a blanket dose of urea (35 kg ha-1, triple super phosphate (TSP) (80 kg ha-1), murite of potash (MoP) (40 kg ha-1) and Sulphur (60 kg ha-1). The growth and yield of mungbean was significantly affected by foliar application of different levels of Zn and B. Results revealed that foliar application of Zn at the rate of 0.6% and at the rate of B 0.6% along with recommended dose at 45 days after sowing increases the branches/plant, fresh weight (g), dry weight (g), chlorophyll content, flower/plant, pod/plant, seed/pod thereby increase seed yield. Therefore, the foliar spray of 0.6% Zn significantly increased and influenced 1000 seed weight (g), decreased days to flowering, increased number of seed/pod and yield ton/ha along with blanket dose of Urea, TSP, MoP, gypsum might be considered as suitable dose for mungbean production in southern region of Bangladesh.

Bu çalışma, Eskişehir Geçit Kuşağı Tarımsal Araştırma Enstitüsü (EGKTAE) Tavuk Islah işletmesinde ıslahı gerçekleştirilen 2 saf baba (B1 ve B2) ile 3 saf ana (A1, A2 ve A3) hattında 14-42 haftalar arasında yürütülmüştür. Tüm saf hatlarda artan yaşla birlikte FPD skorlarında artış görülmüştür. Canlı ağırlıkların daha yüksek olduğu baba hatlarında (B1 ve B2) 14 haftalık yaşta daha düşük FPD skorları görülürken, 42 haftalık yaşta ana hatlarından (A1, A2 ve A3) daha yüksek olmuştur. Ana hatlarında 30 ve 42 haftalık yaşlarda baba hatlarına göre daha yüksek yumurta verimi ve kuluçkalık yumurta verimi elde edilmiş ve hatlar arasındaki farklılıklar önemli bulunmuştur (P<0,01). Yumurtlama döneminde A1, A2, A3, B1 ve B2 saf hatlarında gerçekleşen kuluçkalık yumurta oranları sırasıyla %98,55, %96,68, %97,75, %96,39 ve %97,23 olarak belirlenmiştir. Saf hatlarda yumurta ağırlıkları bakımından farklılıklar önemli bulunmuştur (P<0,01). Döllülük oranları bakımından genotipler arasında önemli farklılıklar belirlenmiştir (P<0,01). Ebeveynlerin 14, 20, 30 ve 42 haftalık yaşlarındaki canlı ağırlıkları ile FPD skorları arasında belirlenen korelasyon katsayıları sırasıyla 0,70, 0,64, 0,72 ve 0,67 bulunmuştur (P<0,01). 42. hafta yumurta verimi ve kuluçkalık yumurta verimi ile FPD değerleri arasında -0,56 ve -0,54’lük korelasyon katsayıları belirlenmiştir (P<0,01). Döllülük oranları ile canlı ağırlıklar arasındaki korelasyon katsayıları önemli bulunmamıştır. Canlı ağırlıklar ile yumurta verimi ve kuluçkalık yumurta verimi arasındaki önemli düzeyde negatif yönlü korelasyonlar bulunmuştur (P<0,01). Sonuç olarak, CA ve FPD düzeyleri baba hatlarında daha yüksek bulunurken, KYV bakımından ana hatları üstünlük sağlamıştır. Artan CA ile FPD düzeyindeki artış üreme performansındaki düşüşe katkı sağlamış olsa da döllülük oranı üzerinde olumsuz bir etki ortaya çıkmamıştır.

The purpose of this study was to determine the effects of selenium, vitamin E, vitamin A, and vitamin D3 treatments on reproductive parameters in Awassi sheep fed solely dry grass and grain stubble during the breeding season with estrus synchronization. Seventy-five sheep were implanted with intravaginal sponges containing 20 mg of flugestone acetate for 9 days for estrus synchronization. On the day the sponges were inserted, the first group received an intramuscular injection of a supplement containing 200,000 IU of vitamin A, 30,000 IU of vitamin D3, and 20 mg of vitamin E, as well as a supplement containing 1 mg of sodium selenite and 60 mg of vitamin E. The second group was the control group, with no supplementary vitamin injected. On the day of sponge removal, the sheep received intramuscular injections of 500 IU PMSG and 250 mcg cloprostenol sodium in both groups. The sheep in the first group were given a second injection of the supplement on the same day that contained 20 mg of vitamin E, 30,000 IU of vitamin D3, and 200,000 IU of vitamin A. The sheep that showed signs of estrus were mated naturally after the estrus synchronization. Estrus rates were 86.11% and 85.29%, conception rates were 74.19% and 58.62%, pregnancy rates were 63.88% and 50%, lambing rates were 100% and 100%, and litter size was found to be 126.08% and 123.52% in Group I and II, respectively (P=0.858). Although there was no significant difference in the reproductive characteristics between the groups (P>0.05), Group I had a greater pregnancy rate and litter size. During the breeding season, it is believed that the regular application of vitamin and mineral supplements on a program basis in sheep fed only dry pasture and grain stubble contributed to fertility.

In the study, the impact of employing vermicompost to boost oil rose (Rosa damascena Mill.), a native of Isparta province, to improve yield and nutrient content, was explored. Four different doses (V0: 0 kg ha-1, V1: 1000 kg ha-1, V2: 2000 kg ha-1, and V3: 3000 kg ha-1) of vermicompost were tested in the field conditions at 3 replicates. Vermicompost was applied to the canopy projection area and incorporated into the soil. Flower harvest was started on April 30, 2018, and throughout 20 days, the blooming flowers were collected and weighed daily basis. Following the harvest, leaf samples were collected from the plants, and the concentrations of certain macro and micronutrients were assessed.The study's findings demonstrated that applying vermicompost boosted the yield of oily rose blooms. The greatest yield value was determined to be 5850 kg ha-1 at a vermicompost dose of 2000 kg ha-1, which was 660 kg ha-1 greater than the control application. It was observed that vermicompost treatments had no significant influence on plant nutrient concentrations.  This condition is assumed to be related to the removal of minerals from the plant during harvest. The findings indicate that the usage of vermicompost can contribute in the production of oil roses, and a dose of 2000 kg ha-1 can be suggested. This research establishes the feasibility of employing vermicompost in oil rose cultivation and sets the framework for future research.

In Ethiopia livestock feed shortage and soil acidity are serious problems. In recent years sweet lupins (white and blue species) were introduced as multipurpose crops in the country. However, there is no information about their nodulation potential. This study was conducted to evaluate nodulation potential of these sweet lupins and their effect on nitrogen (N) and phosphorous (P) content of the soil. Seven lupin varieties were evaluated using factorial arrangement (seven varieties * two inoculations) in a randomized complete block design in two locations for two years. The result showed that effect of inoculation and location was not significant (P > 0.05) on biomass, seed, nodule number and soil parameters. While the effect of variety was significant (P < 0.05) on nodule parameters. Its effect on dry biomass and seed yields was also significant in either of the years. Variety and year had no effect on soil N and P contents. In the first year, blue sweet lupin entries had the highest nodule number per plant, 222 nodules.  In the second year similar nodulation performance was observed among species and varieties. Soil N and P were not affected by varieties and inoculation. In addition to their yield advantage, compared to the sweet white entries, blue sweet lupin varieties had high potential in nodulation. Therefore, these introduced sweet blue lupins can be used as multipurpose crops in acidic soils of Ethiopia.

Foods for special medical purposes are specially produced or formulated with the intention of regulating children's diets for specific nutrition applications, and used under medical surveillance. These food should not offer a microbiological risk to human health as well as their compositions. The purpose of this study was the microbiological evaluation of foods for special medical purposes used in children’s diet. For this evaluation, eleven imported foods for special medical purposes that were sold in Ankara-Turkey were analyzed in terms of Salmonella spp., coagulase positive staphylococci, staphylococcal enterotoxin, Escherichia coli, Escherichia coli O157, Enterobacteriaceae, Listeria monocytogenes, and Bacillus cereus. The bacterial examinations were done according to each related EN ISO standart methods. In result of the examination, the microbial growth was not observed on the food samples. In conclusion, the samples investigated have no microbiological risk. Also, consumers should examine their expiration dates during purchase because the expiration dates declared on the foods have showed their microbiological stability.

While shellfish species are widely consumed due to their nutritional advantages, they are also among the top eight food items for food-borne allergies. Five distinct thermal processing techniques were applied to the crustacean to investigate the tropomyosin level variations caused by heat processing. Fresh shrimp and prawns were utilized as controls for the determination of allergen-encoding genes. Prior to molecular analysis, the proximate composition and acidity of raw and processed samples were also performed. The yield and purity of DNA were also determined. Melting curve and gel electrophoresis tests verified the existence of allergen-coding genes. Thermal processing procedures affected the proximate composition, particularly the total protein and fat concentrations, according to the findings. Following the heat treatment, the pH levels decreased, particularly in the grilled samples. There were also significant differences in the quantity and quality of the extracted DNA. Regardless of crustacean species, the tropomyosin-encoding gene was detected in both fried and grilled samples. These findings demonstrated that RT-PCR identification and validation of the crustacean allergy gene by gel electrophoresis might be a reliable approach for the thermally treated shrimp and prawn samples. This study shows that investigating the allergen coding gene might provide a viable way for detecting food-borne allergens in other thermally processed food items, which are becoming more concerned about food safety.

Böcekler, birçok farklı habitata uyum sağlayabilen en başarılı türlerden biridir. Böceklerin bu özelliği onların evrimsel açıdan güçlü becerilerini göstermektedir. Şimdiye kadar tanımlanan türlerin yaklaşık %80’inden fazlası Insecta’ya aittir. DNA dizisi teknolojisindeki gelişmeler ve düşük maliyet, araştırmacıların birçok böcek türünün tüm genomlarını dizilemesine izin verdi. Karşılaştırmalı genomik yaklaşımı, böceklerin hızlı ve başarılı adaptasyonunun altında yatan moleküler ve evrimsel mekanizmaları ortaya çıkarmak için güçlü araçlardan biridir. Protein aileleri ve kopya sayıları, türlerin evrimsel ihtiyaçlarını ortaya çıkarmak için kilit faktörlerden biridir. Farklı böcek taksonları kullanılarak böcek evrimi üzerine çeşitli çalışmalar yapılmıştır. Bununla birlikte, bu çalışmalar gen ailesinin evrimi ve filogenetik ilişkilere odaklandı. Bu çalışmada, protein familyalarını ve bunların kopya sayılarını ve böceklerdeki varyasyonlarını belirlemek için yirmi böcek türünün genomları incelenmiştir. Sonuçlar, böceklerin temel protein ailelerini (Reseptör proteinleri, Pkinaz, Tripsin) temel yaşam görevlerini yerine getirmek için benzer kopya numaralarıyla paylaştığını gösterdi. Ek olarak, birkaç protein ailesinin bazı türlerde farklı kopya sayılarına sahip olduğu bulundu, bu da her türün adaptasyon ihtiyacının farklı olduğunu gösterdi. Bu çalışma aynı zamanda böceklerdeki birkaç proteinin varyasyonunu da vurguladı.
