Genetics, Development and Functional Genes of Insects

Dear Colleagues,

Insects exhibit remarkable genetic diversity within and between species. This diversity plays a crucial role in their adaptation to different environments and ecological niches. Insects often exist in large populations, and the study of genetic variation within and between populations provides insights into evolutionary processes and adaptation. Genetic diversity can be observed within a single insect species (intraspecific) and between different species (interspecific), which is crucial for conservation and pest management.

The development of insects is a complex and highly regulated process that involves distinct stages, from egg to adult. This complex life cycle is regulated by intricate genetic and hormonal mechanisms. Juvenile hormones and ecdysteroids play crucial roles in orchestrating the transitions between developmental stages. These hormones regulate molting, metamorphosis and the development of specific structures. Understanding the development of insects is crucial for various fields, including agriculture, ecology and entomology. The study of developmental biology provides insights into the mechanisms that drive the incredible diversity of insect forms and life histories.

Functional genes in insects are responsible for a variety of biological processes, including development, reproduction, metabolism and responses to the environment. These genes contribute to the diverse adaptations and behaviors observed in different insect species. For example, insect olfactory genes, including odorant-binding proteins, chemosensory proteins and odorant receptors, are often highly specific, allowing them to respond to particular pheromones or odors associated with food sources or mates. When an odor molecule binds to an olfactory receptor, it triggers a series of molecular events leading to a nerve signal that is interpreted by the insect's brain. Understanding these molecular processes helps researchers decipher how insects perceive and respond to different scents. Olfactory molecular biology involves studying the genes and genetic mechanisms that underlie the development and function of olfactory receptors. This knowledge can be crucial for manipulating insect behavior or developing novel pest control strategies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Genes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
