Review On Locusta Migratoria Cinerascens (Fabricius, 1781)., Laib Djamel Eddine, Benzehra Abdelmadjid, Laib Imen, Aouzal Badis, Salah Akkal

Journal of Bioresource Management

The migratory locust, scientifically known as Locusta migratoria (Linnaeus, 1758), is a captivating insect species that has drawn the interest of scientists, farmers, and the general public. Recognized for its notorious swarming behavior, this insect has the potential to cause extensive damage to crops, leading to agricultural plagues and food shortages. However, beyond its reputation as a pest, the migratory locust is a subject of scientific fascination due to its intricate life cycle, remarkable ability to undergo rapid and dramatic transformations, and its crucial role within the ecosystems it inhabits. This review delves into various facets of L. migratoria, including …

Establishment Of Hand Rearing Protocols With Respect To Feeding, Physiological And Behavioral Aspects In Abandoned Lion Cubs At Safari Zoo Lahore, Muhammad Azhar, Bushra Nisar Khan, Fahd Haseeb, Muhammad Hassan Saleem, Abdul Rehman, Zahid Iqbal Khan, Muhammad Rizwan Khan

Journal of Bioresource Management

African lion (Panthera leo) being most attractive but vulnerable exhibit of zoos and safaris; need particular attention to breeding plans. At captive sites, lioness neglects newborns commonly; at that stage, hand rearing is preferred. This study will highlight the best practices for hand-rearing lion cubs, including knowledge of early medical issues along with their treatment during the first 4 months of growth. 34 lions (08Male: 17Females: 9Cubs) were housed on 15 acres during 2019-21 at Safari Zoo Lahore. A total of 04 lionesses were found entirely abandoned to 05 newborns (03 males & 02 females). The hand-rearing period …

Utilizing An Extract From Endophytic Fungus, Alternaria Alternata, Isolated From Ricinus Communis L. Leaves As A Biological Agent For Controlling The Migratory Locust In Algeria, Laib Djamel Eddine, Benzehra Abdelmadjid, Laib Imen, Aouzal Badis, Akkal Salah Dec 2023

Utilizing An Extract From Endophytic Fungus, Alternaria Alternata, Isolated From Ricinus Communis L. Leaves As A Biological Agent For Controlling The Migratory Locust In Algeria, Laib Djamel Eddine, Benzehra Abdelmadjid, Laib Imen, Aouzal Badis, Akkal Salah

Journal of Bioresource Management

In this research, we aimed to explore the insecticidal potential of Alternaria alternata, an endophytic fungus derived from the leaves of castor oil plant. To test its insecticidal efficacy, various doses of A. alternata mycoextract were administered to Locusta migratoria L. through both topical and oral pathways. The findings revealed that the insects displayed the highest susceptibility to a concentration of 2 g/L, leading to an impressive mortality rate of 87.5 % and 93.75 % for topical and oral administrations, in the same order. The extract displayed remarkable insecticidal properties, demonstrating LC50 values of 1.09 g/L for the topical …

On Some Teratological Scorpions In The Natural History Museum, London And Checklist Of The Scorpiological Literature On Morphological Anomalies (Arachnida: Scorpiones), Danniella Sherwood, Luis F. De Armas

Euscorpius

Whilst undertaking curation in the collections of the Natural History Museum, London, the senior author came across a jar of scorpions marked ‘scorpions with curled feet’. Further investigation showed this jar was full of scorpions with teratological anatomy. We hereby document and illustrate all of the specimens and discuss their respective anomalies. Furthermore, a comprehensive checklist of the literature on anomalies in scorpions, including giving the life stage and sex where known, is compiled for the benefit of future workers.

Hypothalamic Manipulation Of The Anuran Hpg Axis: Alternative Hormones And A Non-Invasive Administration Route For Amphibian Assisted Reproductive Technologies (Art), Erin Michelle Saylor Dec 2023

Hypothalamic Manipulation Of The Anuran Hpg Axis: Alternative Hormones And A Non-Invasive Administration Route For Amphibian Assisted Reproductive Technologies (Art), Erin Michelle Saylor

Theses and Dissertations

Amidst the amphibian extinction crisis, in situ and ex situ amphibian species conservation initiatives utilize assisted reproductive technologies for optimal genetic management of captive and wild populations. Development of effective, simple, low-cost methods for obtaining gametes for artificial fertilization, sperm biobanking, or natural breeding alleviates obstacles for institutions or programs to apply reproductive technologies. Objectives herein include investigating the efficacy of alternative hormones for inducing spermiation, an alternative hormone administration route for inducing ovulation, exploring the physiological effects of hormone therapy, and utilizing sperm from deceased animals for biobanking.

Advancing Salamander Conservation Efforts In Zoos And Aquaria Through Assisted Reproductive Technologies (Art), Devin Marie Chen Dec 2023

Advancing Salamander Conservation Efforts In Zoos And Aquaria Through Assisted Reproductive Technologies (Art), Devin Marie Chen

Theses and Dissertations

Salamanders are one of the most at-risk taxa in the world due to habitat destruction, pollution, climate change, invasive diseases, and more. This has led to a need for conservation breeding programs that are often associated with zoos and aquaria. Salamanders can be difficult to breed in captivity, though, due to their dependence on specific environmental cues and other unknown factors that stimulate sperm and egg production. To overcome these challenges, assisted reproductive technologies (ART) such as exogenous hormone administration, sperm cryopreservation, and in-vitro fertilization have been developed to increase offspring propagation and maintain genetic diversity. If genetically robust populations …
