Evaluation of insecticides against the cotton bollworm Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) under field conditions in Middle Awash, Ethiopia
Get PDFThe cotton bollworm complex presents a significant challenge to cotton farmers, resulting in substantial yield losses. While insecticides have been employed to manage this pest, ongoing research is crucial for developing new insecticides that mitigate the risk of resistance to current synthetic options. This study aimed to evaluate the effectiveness of selected insecticides against cotton bollworm through a field experiment conducted in the Middle Awash region. Utilizing a randomized complete block design, eight treatments were tested with four replications. Larval population, damage to fruiting bodies, yield, and yield component data were collected and analyzed. Results indicated that the application of various insecticides significantly (P < 0.05) influenced larval populations, fruiting body damage, and overall seed cotton yield. Notably, the combinations of profenofos 40% + alpha-cypermethrin 4% EC and profenofos + cypermethrin 44% EC resulted in yield increases of 88.5% and 76%, respectively, compared to the control group. These findings underscore the practical implications for cotton farmers in Ethiopia and similar regions facing pest challenges. The effective use of these insecticides could substantially reduce yield losses attributed to cotton bollworm infestations, thereby enhancing farmers' financial stability. However, further research should focus on the validation and demonstration of these insecticides under different agro-ecologies of the country
Health assessment of fan mussels in the southern part of the Sea of Marmara
Get PDFThe fan mussel (Pinna nobilis Linnaeus, 1758), a critically endangered species in the Mediterranean Sea, has experienced mass mortality events (MME) due to various pathogens, particularly the protozoan parasite Haplosporidium pinnae. Despite these challenges, the Sea of Marmara (SoM) still has significant populations of fan mussels, with no infection-related MME reported so far. This study aimed to assess the general health status of fan mussels in the SoM and understand the factors that contribute to their survival. The samples were collected on September 25, 2023, around the Kapıdağ Peninsula in the southern part of the SoM, a critical area for fan mussel populations, where a total of 20 live specimens were included in advanced laboratory analysis from four stations. Findings revealed that Haplosporidium and Mycobacterium species were present in P. nobilis across all stations, with higher oxidative stress indicators in the digestive gland tissues. Results also observed different life stages of Haplosporidium in the mantle and digestive gland. Molecular analyses revealed the presence of haplosporidian parasites, Perkinsus sp., and Mycobacterium sp. in some samples. Phylogenetic analysis showed that Haplosporidium isolates form a distinct clade separate from H. pinnae, suggesting they belong to a different species. The detected Haplosporidium species in the SoM displayed genetic differences from H. pinnae found in the Mediterranean Sea, potentially indicating a less virulent variant. This study raised the question of whether interactions between the detected Haplosporidium parasite and other pathogens or region-specific ecological characteristics were effective in the absence of a mass mortality in fan mussels in the SoM
Prevalence of Varroa and Acarapis woodi mites and Nosema in honey bee colonies of Kermanshah Province, Iran
Get PDFVarroa and Acarapis woodi mites and Nosema are the most important bee pathogens and cause a lot of damage to the apiculture industry. This study aimed to investigate the infection of Varroa and Acarapis woodi mites and Nosema among bee colonies in Kermanshah. For this purpose, 25 apiaries with at least 50 colonies were randomly selected, and eight colonies from each apiary were randomly selected for sampling (200 colonies in total). From each colony, 100 adult bees were collected from around and inside the hive and transferred to the laboratory. Also, the bottom debris of each colony was collected separately in unique bags. A 5 × 5 cm piece of wax containing larval cells was also cut from each colony. Varroa debris and neonatal cells were examined for Varroa infection in adult bee samples in the laboratory. The experiments were performed on adult bees to determine infection with Acarapis and Nosema. The results showed that 88% of studied apiaries and 32.5% of colonies were infected with Varroa. Also, 16% of apiaries and 7% of colonies showed Acarapis woodi infection, while 76% of apiaries and 34% of colonies were infected with Nosema. Most Varroa infections were found in adult bees. The results show that high infection with bee parasites, especially Varroa and Nosema, in the apiaries of Kermanshah, requires structural reform, management, and training of beekeepers to reduce these risks
In vitro investigation of the efficacy of myo-inositol (vitamin B8) as an antioxidant and preservative additive for feed safety
Get PDFThe study was carried out to examine the safety and potential activities of myo-inositol as an antioxidant, preservative, hygiene enhancer, and antiviral feed additive in pet nutrition. For this purpose, the antioxidant capacity of myo-inositol was expressed as vitamin C equivalent antioxidant capacity (VCEAC) by MTT assay. The cytotoxic concentration of 50% (CC50) was measured by the linearity between myo-inositol concentrations and the viability of mammalian kidney and liver cell lines. The virucidal and antiviral activities of myo-inositol were determined by the virus titration method on the host cell infectivity of murine norovirus-1 (MNV-1) and expressed as the tissue cell infective dose of 50% using the Spearman–Karber method. One milligram of myo-inositol equals the antioxidant capacity of 0.454 mg of vitamin C. The CC50 was determined between 280 and 966 mg/ml for kidney and liver cell cultures. Myo-inositol exhibited dose-dependently virucidal activity against MNV-1 as a surrogates for pet caliciviruses. In three different antiviral experiments, 50% inhibition concentrations were determined as 0.054, 0.084, and 0.047 mg/ml. This in vitro study presents that myo-inositol might be a potential candidate as an antioxidant, preservative, and hygiene enhancer feed additive against oxidative deterioration and microbial contamination in feed production technology for ensuring feed safety and promoting pet health
Histopathological and Micro-CT Scan Evaluation of the Repair of Large Bone Lesions using Apatite Carbonate and Titanium-Containing Bioactive Glass in a Rabbit Model
Get PDFIn recent years, several techniques have been used to reconstruct large bone fractures, including various scaffolds and bone reparative materials, but the results have not been remarkable. Therefore, this study investigates and compares the effect of new scaffolds based on apatite carbonate and bioactive glasses containing titanium in promoting the healing process of large bone lesions in animal models in laboratory conditions. After constructing the scaffolds, in vivo studies were performed by creating four circular defects in the calvarial bones of 10 adult New Zealand rabbits, and then the cavities were randomly filled with bioactive glass powders containing titanium and apatite carbonate. The survival and proliferation of mesenchymal stem cells through the MTT method and bone defects in the studied groups were evaluated using different diagnostic imaging methods and histological analyses. The XRD and FTIR results confirmed the high purity of the fabricated Bg-Ca and Bg-Ti scaffolds. In the MTT method, the scaffolds made at a concentration of 10 mg/ml had no cytotoxicity against MSCs. Also, in total, microCT scan analyzes and histological findings showed a significant improvement in the healing process in rabbits treated with Bg-Ti and Bg-Ca compared to the group that received the Bg scaffold alone and in the control group
Using Genetically Modified Feedstocks in Broiler Diets; Risks, Perceptions and Facts
Get PDFChicken meat has significantly contributed to people's access to animal protein sources in recent times. However, it fails to garner the same importance from experts in various sectors of public opinion. Therefore, the objective is to obtain expert opinions and present facts from their perspective, as opposed to consumer opinions typically collected in studies of broiler chickens that consume genetically modified feed raw materials.
In some surveys, certain experts who were selected based on their fields of expertise have been found to make errors. The opinions or views of individuals lacking real knowledge on the subject can have negative impacts on both consumers and their environment, who require access to healthy sources of animal protein, as well as the industry and its employees, who rank among the top 11 worldwide
A Comprehensive Review of Herbal and Synthetic Therapeutics in Managing Viral Diseases in Fish Health
Get PDFDisease outbreaks are the main cause of financial loss in aquaculture, resulting in an estimated annual loss of over $10 billion. Fish viral diseases pose a continuous risk to the production of aquaculture, and despite advancements in the industry, approximately 10% of cultured aquatic animals succumb to infectious diseases, resulting in significant losses. Preventing and treating viral diseases in animals and humans is one of the most difficult tasks due to the varying effectiveness of vaccines, interferons, and other medications. While salmonids have been successful in controlling significant bacterial diseases through the use of antibiotics and vaccines, vaccines for viral diseases often prove to be ineffective. Standard antibiotics are not effective in preventing or treating viral diseases in fish. The risk of infectious disease outbreaks, including viral infections, increases with monoculture, as in the case of terrestrial agriculture. Unfortunately, the treatment of viral diseases often fails, highlighting the need for more research to find effective drugs and vaccines to manage viral diseases. This article explores the potential of using herbal and synthetic drugs to combat viral diseases that impact fish populations
