The whitefly, Bemisia tabaci, damages various crops by releasing honeydew and spreading. Although farmers and pest control experts primarily rely on insecticides to manage whiteflies, the notable issue is their tendency to develop resistance to major insecticide categories, posing a significant challenge. This result has led to the improvement of new drugs or insecticide mixtures. In addition, some plant-based studies have been conducted to control whiteflies, and RNA interference (RNAi) technology has been used in recent years. This study aimed to identify the relationships between tobacco, cotton, tomato, and linen miRNAs and odorant-binding protein (OBP) and chemosensory protein (CSP) genes in whiteflies by using in silico approaches. We determined that 115 miRNAs belonging to these plants targeted 13 CSP and 8 OBP genes of B. tabaci. Obtaining findings are important to reduce dependency on chemicals and pesticides in pest management.

The aim of the present study was to determine the the effects of carazolol injection during mating following progestagen + eCG administration on conception rate in breeding season Lacaune ewes. Sixty-two Lacaune ewes were used in the study. On day 0, an intravaginal sponge containing 20 mg flugestone acetate was inserted and left in place for 10 days. On day 10, the sponges were removed, and each ewe received an intramuscular injection of eCG at a dose of 480 IU. Ewes in estrus were mated with a proven rams (ewe:ram ratio of 5:1). Fifty-nine mated ewes were randomly assigned into two groups: control and treatment. In the carazolol group (n = 30), ewes received an intramuscular injection of carazolol (0.01 mg/kg; Simpanorm, Fatro, Italy) on the day of estrus, post-mating. In the control group (n = 29), ewes were not administered any treatment. Pregnancy diagnosis was conducted in all ewes on days 30 and 60 post-mating using transabdominal ultrasonography with a Hitachi EUB-405 device equipped with a 3.5 MHz convex probe. The estrus rate, conception rate, total pregnancy rate, and early fetal death rate were evaluated across all groups. The study results indicated no statistically significant differences between the control group and the carazolol group regarding conception rates (62.1% vs. 66.7%) and total pregnancy rates (79.3% vs. 83.3%). In addition, as a result of repeated ultrasound examinations, no early fetal death was found in the study. In conclusion, carazolol injection during mating following progestagen + eCG administration did not increase on fertility in breeding season Lacaune ewes.

Ruminant hayvanların beslenmesinde kullanılan rasyonlar belirli oranlarda kaba ve kesif yem içermelidir. Besin madde içeriği bakımından zengin olan kesif yemler genelde rasyon maliyetini artırmaktadır. Hayvancılık işletmelerinde bu yüksek maliyetten kurtulmak kaliteli kaba yem üretimine bağlıdır. Ülkemizde faaliyet gösteren hayvancılık işletmeleri yem (besleme) maliyetlerinin azaltılması ve ürün kalitesinin yükseltilmesi amacı ile farklı kaba yem arayışı içindedirler. Bu çalışmanın konusunu teşkil eden soya bitkisi, ruminant rasyonlarında hasıl veya silaj formunda kullanılma potansiyeli olan bir kaba yem türüdür. Bir baklagil yem bitkisi olan soya bitkisi protein içeriğinin yüksek olması (yaklaşık %20) ile kaba yem grubu yemler içinde önemli bir yere sahiptir. Soya bitkisi bu özelliği ile ruminant rasyonlarında temel protein kaynağı olarak kullanılan bazı yem kaynaklarının bir kısmı yerine ikame edilebilmektedir. Nitekim bazı çalışmalarda soya silajının en kaliteli protein kaynağı olarak kabul edilen soya küspesinin yerine bile kısmen de olsa kullanılabileceği ortaya konulmuştur. Bu derlemede soya bitkisinin ruminant rasyonlarında kaba yem kaynağı (hasıl ve silaj) olarak kullanılma potansiyeli hakkında bilgi verilmiştir.

Population growth has increased demand and diversified use of Irish potato which have increased its demand. The crop has become a major source of food and income for many households across the world. However, despite the high potential of about 30 tonnes per hectare (ha), smallholder farmers in Kenya realize low Irish potato yields ranging from 4-8 tonnes per ha due to limited uptake of agricultural technologies. The low yields calls for a profound understanding of the factors influencing the uptake agricultural technologies. The study analyzed the effects of the adoption of agricultural technologies on Irish potato yield in Ol Kalou Sub County. The study considered chemical fertilizer, certified seeds, fungicides, and farm machinery as the four main agricultural technologies that that affect yield. A descriptive cross-sectional research design was used to obtain data from a study population of 21,942 smallholder Irish potato farmers in Ol Kalou Sub County. A multiple-stage sampling technique was employed to generate a sample size of 385 respondents who provided primary data. Data collected was analyzed using endogenous switching regression model using STATA version 17. The study found that the average treatment effect on treated (ATT) was 10.21 bags per acre. In addition, the Endogenous switching regression model showed that the expected yield for the adopter increased by 51.83%. Out of the four technologies, the use of chemical fertilizers had the highest effect of 37% on yield. The study concluded that the adoption of agricultural technologies increases the yield of Irish potatoes. The study recommends that national and county governments should develop policy regulations such as training and extension services, market access, price support and public-private partnerships encouraging farmers to uptake agricultural technologies. The study also recommends that both levels of government should subsidize agricultural technologies, hence reducing the cost of adoption.

The tomato is a significant vegetable in the world on the basis of consumption, nutrition, and extensive use in processed foods. During plant growth and development, amino acids especially exogenous application of proline (Pro), plays a crucial role to increase stress tolerance under various abiotic stresses. Among abiotic stressors, temperature is considered as an important and alarming stressor for plant development and growth. Sometime a significant drop in crop productivity is the outcome of harsh temperature increment. An investigation was carried out at the Horticulture Lab, College of Agriculture, University of Sargodha, during 2021-22 to inspect the role of foliar application of proline under heat stress in tomato plants. Tomato seedlings with true leaves were exposed to high temperatures (25°C [control], 40°C, and 45°C) with exogenous proline sprays of (0, 0.5, 1 and 1.5 mili-molars). Various growth attributes like morphological i-e number of leaves, leaf area cm2, shoot fresh weight (mg), shoot dry weight (mg), root fresh weight (mg), root dry weight (mg), and physiological [photosynthetic rate (µ mol/m-2s-1)], chlorophyll contents (spad), stomatal conductance (µ mols m-2 s-1 transpiration rate (µ mol/m-2 s-1),)] were studied. The findings indicated that foliar application of proline at 1.5 mM under heat stress on 40oC and 45oC was found to be more advantageous to improve growth attributes like number of leaves (12.2), leaf area (8.3 cm2), shoot length (10.39 cm), shoot fresh weight (1.88 mg), shoot dry weight (0.28 mg), root dry weight (0.20 mg), and remediated the detrimental effect of heat stress in tomato plants. The variation between control and proline treated heat-stressed plants supported that proline may have a function in alleviating heat stress.

The objective of this study was to evaluate the effects of palm oil, African walnut oil and their blends on hematological, inflammatory, and some oxidative stress markers in high fat diet (HFD) obese-induced Wistar rats. Obesity was induced for 60 days and treated for 28 days using edible oils [palm oil, African walnut oil, palm oil: African walnut oil (50:50) and palm oil : African walnut oil (60:40)] and orlistat (10 mg/Kg). Thereafter the animals were sacrificed, blood was collected for hematological studies and the preparation of the serum, while the organs harvested were used to prepare organ homogenates. Serum and organ homogenates were used for the evaluation of inflammation and oxidative stress markers. Results showed that the oils utilized were confirmed to be of high quality through their good stability indices (peroxide value: 2.52-3.87meq O2/Kg; p-anisidine value: 8.24-12.33, TOTOX value: 13.37-19.46,). Looking at the haematological study, animals that received the HFD presented the lowest (p<0.05) hematocrit and Platelet. PO:WO (50:50 and 60:40) significantly (p<0.05) decreased the granulocytes concentration in the blood of rats. PO:WO (50:50) significantly (p<0.05) increased the lymphocyte concentration while 100% PO increased the mid-size white blood cells level in the animals. Serum levels of inflammation markers were higher (p<0.05) in the negative control group (354.44-385.82 pg/mL) compared to the other groups (147.22-271.55 pg/mL). The analysis of oxidative stress parameters revealed that the administered oils and orlistat generally exhibited good protections compared to the normal and negative control groups, which might be due to the presence of omega-3 fatty acids and bioactives such as β-carotene and vitamin E which have good antioxidant and anti-inflammatory properties. It can be concluded that these oils have a role in protecting against obesity through their effects on oxidative stress, hematology, and inflammatory cytokines.

The aim of this study was to determine the relationships between body defects, egg and chick quality and hatching results at different age periods of the laying period of partridges raised in production conditions (cage system). The study was based on three different periods. The first period is the pre-peak egg production period (˂200 eggs), the second period is the peak egg production period (˃200 eggs) and the third period is the post-peak egg production period (˂200 eggs). These periods also represent the age of the animals. As material, 432 female and 216 male partridges in their first egg production year were used. The study was organized according to the random plots experimental plan. There were changes in body defects and other health parameters depending on egg production periods. Foot-pad dermatitis and elbow burns increased with increasing age. Parent partridges had better head, neck, back, chest and tail feather condition before peak egg production. Egg weight increased with advancing age. Hatching egg characteristics such as excessively pointed eggs and eggs with calcium deposits decreased in the peak and post-peak yield period. Eggshell transparency increased with advancing age. Fertility was higher in the pre-peak egg yield period compared to other periods. Hatchability was lower after the peak period. Tona score of chicks decreased with age. There were weak negative and positive phenotypic correlations between many traits. Practices that prevent body injuries in the early egg production period and deteriorating feather condition with advancing age, decreasing shell opacity, deterioration in hatching performance and chick quality traits in partridges will be beneficial in terms of increasing both production performance and animal welfare.
