Advances in Animal Science and Zoology. Volume 15 begins by presenting the main advances of artificial insemination and timed artificial insemination, highlighting the technical parameters, advantages, and influencing factors in an effort to discuss practical and current strategies for the improvement of the herd via artificial insemination programs.

Following this, the authors provide current knowledge on the influence of insecticide resistance in Culex quinquefasciatus in India, as well as the governing molecular mechanisms including gene interactions and gene regulation. The potential impact of the latest findings on aspects of research in the field, associated issues and probable solutions is also addressed.

A study on eusocial Hymenoptera, a large order of insect, is included. The factors that determine castes are addressed, and the varying methods of initiation of reproduction by workers in primitive and advanced eusocial species are outlined.

This compilation goes on to discuss Mycoplasma synoviae, an important poultry pathogen that causes airsacculitis, synovitis, and eggshell apex abnormalities. M. synoviae infections cause significant economic losses to the poultry industry due to the culling of birds, increased carcass condemnation and decreased egg production.

The authors review the most relevant scientific contributions to the understanding of brain mechanisms related to working memory using macaques as a study model. The neurophysiological mechanisms of working memory in the macaque have been thoroughly explored, which has given rise to unprecedented advances in the understanding of the neurophysiological mechanisms that underlie this type of memory in other mammals, including humans.

The conclusion centers on the utmost task of a biologist: knowing the taxonomic status of the organism on which the study is focused. A taxonomist fulfills this task by distinguishing the salient characteristics of the organism concerned, giving it an appropriate name and placing it to taxonomic hierarchies.
