The average wing beat frequencies during free flight of local Drosophila melanogaster was found to range from 215.63 ±5.26 to 261.20 ±6.53 Hz, from the smallest to large-sized flies respectively. The significant difference in wingbeat frequency between the two groups is due to the distinct differences in wing size and body weight. Variations seen within the group is a function of several factors like insect body weight, wing dimensions, age, metabolic status, locomotory requirements and ambient climatic conditions.","PeriodicalId":355136,"journal":{"name":"Asian Journal of Research in Zoology","volume":"71 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141653241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth coefficient (b) ranged from 1.196 to 2.649, with moderate to high correlations (r) between 0.437 and 0.798. Values of (b) were less than 3 indicating a negative allometric growth pattern, whereas weight increased at a lower rate than length. The condition factor (K) ranged from 1.966 ± 0.696 to 3.856 ± 3.856, suggesting the fish were in good health condition throughout the sampling sites.

Among animals, adult female mosquitoes of the Anopheles genus are infamously labelled the deadliest to humans in terms of the number of deaths they cause each year. In this scientific paper, an analysis is given over what other direct and indirect factors can be considered when classifying a species of animal as 'dangerous'. It discusses and concludes exactly why they make it more of a danger to human health and safety than others. This is done utilising a brand-new, categoric scale — which has been dubbed the \"Crespo scale\" — created and designed to categorise all animal species from categories 1–5. One posing the least danger and five the most. The categorisation is performed by examining factors relevant to the animals themselves, which include the estimated Population Size (PS) and Mortality Rate (MR). The hypothesis is that species possessing a larger PS and a higher MR will be placed further up on the scale and thus are more likely to be a threat. Ultimately, both PS and MR are quantifiable factors that can be used to measure and categorise a species' level of danger in a less biased and more accurate, consistent way. However, the factor of MR can often be indirectly influenced by human-related factors that apply to the human development of a country and its general populace.","PeriodicalId":355136,"journal":{"name":"Asian Journal of Research in Zoology","volume":"41 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140728012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed to assess the diversity, relative abundance, and distribution of collected specimens to understand their patterns within the study area. \u0000Location and Duration of Study: Tick specimens were Collected from the Bannu and Lakki Marwat districts of Khyber Pakhtunkhwa, spanning from August 2021 to June 2022. \u0000Methodology: Visual encounter surveys were conducted, involving both daytime and nighttime observations, to collect specimens from diverse host animals, totaling 106, including cows, buffalo, goats, and dogs. Following the collection phase, a total of 312 specimens were carefully gathered and transported to the laboratory for further analysis. Upon arrival in the laboratory, the collected specimens were carefully arranged and preserved in Eppendorf tubes filled with a 70% ethanol solution. The preservation process aimed to maintain the integrity of the specimens for subsequent examination. The identification process involved a thorough morphological analysis, where authentic literature, updated taxonomic keys, and observation of morphological parameters were utilized. \u0000Results: The specimens subjected to examination and identification belonged to the Ixodidae family of hard ticks, encompassing two genera: Hyalomma and Rhipicephalus. Within these genera, eight distinct species were recognized in the current study in which a higher prevalence of female ticks across various species were observed. From the Hyalomma genus, the identified species were H. asiaticum, H. anatolicum, H. detritum, and H. impeltatum. The Rhipicephalus genus included R. haemaphysaloides, R. microplus, R. sanguineus, and R. turanicus. R. microplus emerged as the most dominant species, with a count of 126 individuals (SOR=100% and AQ=40.38%). Conversely, H. detritum, H. impeltatum, R. sanguineus and R. turanicus were identified as satellite species. Additionally, H. anatolicum, R. haemaphysaloides, and nymphs were categorized as co-dominant. Moreover, this study reports the first-ever occurrences of H. asiaticum and H. detritum in Khyber Pakhtunkhwa, specifically in the Lakki Marwat district. Furthermore, R. haemaphysaloides is possibly reported for the first time in both the Bannu and Lakki Marwat districts. \u0000Conclusion: This research presents preliminary findings on the diverse tick population in regions where animal husbandry plays a crucial role in the local economy. The Lakki Marwat district exhibited the highest diversity indices compared to Bannu. The observed prevalence of ticks in the studied areas emphasizes their significant impact on domesticated animals. Cattle exhibit the highest infestation rates, followed by buffalo and goats. The current taxonomic work may require improvement.","PeriodicalId":355136,"journal":{"name":"Asian Journal of Research in Zoology","volume":"8 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140434989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Labeo rohita (Rohu) is commercial species of Pakistan and main food item. The base of this study is to enhance the growth of Labeo rohita under special dietary condition. The aim of this research project was to check the effect of traditional herb Aloe barbadensis on Growth rate, FCR, Survival rate and Gastrointestinal villi histopathology of Labeo rohita fed on different Aloe barbadensis concentration containing diet. Methodology: Initial stocks of 120 Labeo rohita fingerlings having average weight 14.30 +3.51g were bought from Government Fish Hatchery, Faisalabad. Aloe barbadensis leaf’s powder were prepared ad mixed with different concentration of conventional feed ingredients like such as fish meal, rice polish, corn, wheat bran. Four treatments were designed including a control and Aloe barbadensis incorporated in the fish feed at 0%, 05% and 10%, 15% which were administrated for a period of 180 days. This feeding trial remains continued till 180 days in aquarium. Iso nitrogenous diets having protein level 33±1g.45 but different concentration of Aloe barbadensis were prepared and fed to fingerlings. Ingredients quantity was calculated by using Pearson square method. Conventional feed ingredients i.e. fish meal, rice polish, corn and wheat brane were used in feed in pellet forn. At the end of feeding trial three fish from each aquarium were selected randomly for gastrointestinal analysis. Gastrointestinal Villi parameters like length, width of intestine villi were measured at the end of trail. Results: According to results, different levels of Aloe barbadensis leave’s powder had significant positive effect upon Growth, Survival rate, and FCR. Results showed that Aloe barbadensis at 15% (T3) resulted in improved growth rate, Survival rate and feed conversion ratio (FCR). The Aloe barbadensis-treated groups showed improvement in intestinal villi length, width and gap between villi.
