“…Some species are pests of crops of edible and ornamental aquatic plants, and these, and others verified as phytophages, have been considered for biological control of nuisance aquatic 'weeds' (e.g. Hashimoto 1985;Earle et al 2013;Andersen et al 2015).…”

Polypedilum johannseni Sublette & Sublette (= Chironomus (Polypedilum) anticus Johannsen), described from Indonesia, is recorded from Australia, where larvae are newly reported to feed on species of the aquatic fern Azolla Lam. (Salviniaceae). We extend the Australian distribution for the species that was reported previously as Polypedilum ‘nr seorsus’ from northern Australia. Review of the species in Asia shows previously known presence in Singapore as Polypedilum anticus and in Thailand and the Philippines, where the larva was reported to feed on Azolla. In China, Polypedilum johannseni is reported from a diverse range of aquatic host plants, including Azolla. We also newly report the species from Japan, where larvae feed on hybrid Azolla cristata × Azolla filiculoides and Trapa japonica Flerow (Lythraceae). We review the taxonomy, provide new illustrations, record and map the wider distribution and comment on morphological variation. Here, we also redescribe the Australian Polypedilum seorsus (Skuse) with which P. johannseni has been confused, and from China, we redescribe Polypedilum tigrinum Hashimoto, the larva of which is a proven aquatic phytophage that co‐occurs with several species of Polypedilum, including P. johannseni.

“…Polypedilum is a worldwide genus that includes at least 440 described species (Andersen et al 2015) with an internal classification system of subgenera that is unstable and not fully validated from phylogeny (e.g. Kawai et al 2012;Cranston et al 2016).…”

Aquatic weeds, including invasive species, are a worldwide problem. The presence of aquatic weeds poses several critical issues, such as hindering the continuous flow of water in irrigation channels and preventing the proper distribution of adequate water quantities. Therefore, effective control measures are vital for agriculture and numerous downstream industries. Numerous methods for controlling aquatic weeds have emerged over time, with herbicide application being a widely used established method of weed management, although it imposes significant environmental risks. Therefore, it is important to explore nonchemical alternative methods to control existing and emerging aquatic weeds, potentially posing fewer environmental hazards compared with conventional chemical methods. In this review, we focus on nonchemical methods, encompassing mechanical, physical, biological, and other alternative approaches. We primarily evaluated the different nonchemical control methods discussed in this review based on two main criteria: (1) efficiency in alleviating aquatic weed problems in location-specified scenarios and (2) impacts on the environment, as well as potential health and safety risks. We compared the nonchemical treatments with the UV-C-radiation-mediated aquatic weed control method, which is considered a potential novel technique. Since there is limited published literature available on the application of UV-C radiation used exclusively for aquatic weed control, our review is based on previous reports of UV-C radiation used to successfully control terrestrial weeds and algal populations. In order to compare the mechanisms involved with nonchemical weed control methods, we reviewed respective pathways leading to plant cell death, plant growth inhibition, and diminishing reemergence to justify the potential use of UV-C treatment in aquatic habitats as a viable novel source for aquatic weed control.
