Special Issue Information

Dear Colleagues,

Under the pressures of global climate change and agricultural intensification, the ecological adaptation of insect pests has become a critical factor influencing ecosystems and crop production. Insect pests exhibit remarkable ecological adaptations that enable their survival, reproduction, and expansion in diverse environments. These adaptations include phenotypic and behavioral plasticity, physiological tolerance, host-plant interactions, ecological resistance mechanisms, etc. Understanding these adaptations is critical for predicting pest outbreaks, developing targeted control strategies, and mitigating crop losses. By integrating insights from ecology, evolutionary biology, insect physiology and biochemistry, and molecular biology, this topic aims to unravel the genetic and phenotypic underpinnings of insect pest adaptation, explore their ecological and evolutionary consequences, and translate these findings into innovative insect pest management solutions.

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. Insects 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.

The wide distribution of Frankliniella occidentalis is largely due to its extreme temperature adaptability. In current studies, most scholars consider environmental changes to be the main factor affecting insect temperature adaptation. However, our previous studies have shown that the adaptability of F. occidentalis to extreme temperature conditions can be strengthened through domestication. In this study, the population of F. occidentalis raised in the laboratory for a long time (2008–2022) under relatively constant temperature and humidity conditions was used as the experimental material. Over 14 years, changes in temperature tolerance after the same high- and low-temperature stress were evaluated by comparing the survival data of the 2010 population, 2016 population (more than 100 generations), and 2022 population (more than 200 generations). The survival data and LT50 values demonstrated significant stage- and sex-specific differences in thermal tolerance: The cold tolerance of F. occidentalis improved significantly, with LT50 decreasing from −12.5 °C (P2010) to −13.4 °C (P2022) for females and −11.5 °C to −13.0 °C for males. Notably, male adults showed higher survival rates than females at −14 °C and −15 °C. Meanwhile, heat tolerance increased most markedly in 2nd instar larvae (ΔLT50 = +4.1 °C). These findings indicate an environment-independent evolutionary pathway within the population, providing a new research direction for insect population evolution. Full article
