Special Issue Information

Dear Colleagues, 

Upland cotton (Gossypium hirsutum) is the principal source of natural fiber in the cotton industry, and is also a source of products such as linter and seeds, which contribute to its extensive cultivation. Cotton is grown in tropical to temperate locations between 30°N and 30°S, where warm summers promote its development. There are various types of cotton grown in over 90 countries, with cropping techniques ranging from low- to high-input technologies. Cotton is a plant that takes a long time to develop, with up to six months elapsing between sowing and harvesting; as a result, it can become infested with a variety of arthropod pests, some of which are common worldwide, while others are particularly significant in specific regions, necessitating both common and specialized pest management strategies. Cotton IPM has evolved through the use of biotechnologies to improve plant resistance to pests, the introduction of novel insecticides and biological control agents, and methods of mitigating pests’ resistance to these management tools.

Therefore, we invite authors to submit research and review articles to this Special Issue of Insects on different levels of cotton IPM for dealing with arthropod pests.

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 250 words) can be sent to the Editorial Office for assessment.

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 cotton bollworm, Helicoverpa armigera (Hübner), a cosmopolitan agricultural pest, inflicts severe impacts on global agriculture. As a poikilotherm, it was highly susceptible to climate change, yet critical gaps persist in understanding how its sensitivity interacts with climatic shifts—knowledge essential for integrated pest management (IPM). We, therefore, analyzed H. armigera’s susceptibility to temperature variations using long-term pest population and meteorological data from Maigaiti and Bachu Counties (southern Xinjiang) and Shawan County (northern Xinjiang). The results showed H. armigera populations increased overall, with reduced interannual fluctuation magnitude. The main meteorological factors influencing the interannual population changes of H. armigera in Maigaiti, Bachu, and Shawan were Tmax difference in winter (98.0%), Tmin difference in May (80.7%), and Tmin difference in July (99.4%), respectively. Higher winter temperature (particularly February) reduced the spring population sizes across all three regions, with only the population in Bachu showing a significant correlation. For annual populations, warmer winter caused a significant decline in Bachu, a marked increase in Maigaiti, and a non-significant rise in Shawan. Summer temperature below 33 °C boosted populations in all regions; above 33 °C, the Maigaiti population declined non-significantly, while the Bachu population dropped significantly. Climate warming advanced the pest’s first appearance, delayed its disappearance, and extended its active period, increasing population size—a trend projected to intensify in the future. Maigaiti and Shawan populations were governed by Tmax in winter and Tmin in July, respectively, whereas the Bachu population was constrained by temperature differences during multiple key growth and development periods throughout the year. These divergent regulatory patterns and climatic responses reflect varying vulnerability levels, providing a theoretical basis for targeted H. armigera control. Full article

Thrips pests have become an increasing concern in cotton fields in Xinjiang. Frankliniella intonsa is the primary thrips species during the flowering and boll stages, causing boll stiffening or cracking. However, limited studies have been conducted on controlling F. intonsa. In this study, using a leaf-tube residue method, we evaluated the susceptibility of F. intonsa field populations to three insecticides (spinetoram, imidacloprid, and acetamiprid) collected from different geographical sites across major cotton planting areas in Xinjiang. The results showed that F. intonsa populations exhibited very high susceptibility to spinetoram, ranging from 0.003 mg L−1 in the Shihezi population to 0.036 mg L−1 in the Korla population. The susceptibility of F. intonsa to imidacloprid and acetamiprid varied considerably among different field populations, with the relative resistance of 33.00 and 25.71, respectively. Reduced susceptibility to all three insecticides was detected in the Korla and Manasi populations, highlighting the importance of implementing effective resistance management and alternative control strategies. These findings provide valuable information for the appropriate control of F. intonsa in Xinjiang. Full article
