Special Issue Information

Dear Colleagues,

It is a pleasure to introduce the new Special Issue of Applied Sciences, titled “Advances in Pest Treatment and Plant Protection”.

Plant damage and yield losses due to pests are a global problem threatening food security, causing critical economic losses, and increasing hunger worldwide. Furthermore, climate change and globalization are two main factors increasing the spread of pests and, therefore, crop protection and pest management are societal challenges requiring attention if we desire to achieve a healthy and sustainable agriculture allowing food access worldwide. New solutions and further research for pest management and plant defense against pests with integrated economically viable, ecologically careful, and safe for human health approaches are necessary and of urgent need.

We welcome original research, reviews, and opinion articles covering all related topics, including (1) molecular plant–herbivore interactions, (2) new technologies in plant protection and/or pest management, (3) genomic tools for plant protection, and (4) field studies of new pest treatments.

In contrast to most other Drosophila species that infest processing (overripe) strawberries, the spotted-wing drosophila (SWD) can also infest firm and ripe fruit intended for the fresh market. However, fresh fruit infestations of this invasive species did not become an economic problem for California growers until a decade after SWD’s first detection in California strawberries in 2008. This outbreak corresponds to the development of reported insecticide resistance in SWD populations from strawberry and other berry crops following years of incidental exposure of insecticide applications against other key pests. The objective of this study was to determine the current levels of Drosophila infestation in fresh market and processing strawberries which would inform the choice of insecticides to use for control. We sampled fresh market and processing strawberries from 17 fields over a two-year period in the three major strawberry production areas of California and determined the numbers of emerged SWD and non-SWD Drosophila adult flies. In addition, since holding fruit for adult emergence to determine species composition is impractical for making rapid control decisions and could be inaccurate due to potential interspecific competitions among larvae in the fruit, we developed a TaqMan assay that facilitates larval identification.

Botanical biopesticides have emerged as sustainable and eco-friendly alternatives to synthetic pesticides, whose indiscriminate use leads to several drawbacks to human and environmental health. To the best of our knowledge, there have been no reports on M. pubescens’ bioactivity on phytopathogens affecting crops as a potential fungicide or antifeedant. This has encouraged us to investigate the potential of the roots of this plant as a source of biopesticides. The present study reports on the evaluation of the roots extract from Magonia pubescens A. St.-Hill., a species from the Cerrado (Brazilian savannah), on the phytopathogenic fungi Botrytis cinerea, Fusarium oxysporum, and Alternaria alternata. In addition, its insect antifeedant effect was assayed against Chrysodeixis chalcites. Thus, an in vitro test-assay was used to determine the fungicide potential (percentage growth inhibition, % GI) of the ethanolic extract of this plant species, whereas a leaf-disk bioassay on the 5th instar larvae of C. chalcites was performed to evaluate its insecticidal potential. The ethanolic extract was further fractionated by liquid–liquid partition using solvents of increasing polarity. The hexane/dichloromethane fraction exhibited a moderated potency and was similar to the ethanolic extract on the three assayed fungi (around % GI 30 at 1 mg/mL), whereas the n-butanol fraction showed a slight improvement of the fungicide effect against B. cinerea (% GI 39.18 at 1 mg/mL). Moreover, the ethanolic extract exhibited a strong antifeedant activity, with a refusal rate (FR) higher than 90% in both choice and non-choice assays against C. chalcites, while the ethyl acetate and n-butanol fractions behaved as appetite suppressors. These results highlight M. pubescens as a promising source of biopesticides and deserve further investigations to optimize extraction procedures. Full article

Cercospora leaf spot disease is a serious problem for lettuce cultivation worldwide. Cercospora lactucae-sativa, the causative agent of leaf spot disease on lettuce, was treated with non-thermal atmospheric pressure gliding arc (GA), tesla coil (TC) and dielectric barrier discharge (DBD) plasmas for the in vitro fungal inactivation of both mycelial growth and conidial germination. The fungus was exposed to the three plasmas individually for 5, 10, 15 and 20 min. The results showed that DBD plasma inactivated fungal growth during all exposure periods, and the highest inhibitory effect was caused by exposure to DBD plasma for 20 min, at 93.33% inhibition. The germination of fungal conidia was completely inactivated after exposure to all three non-thermal plasmas for 5 min, as observed 4 and 24 h after incubation. The pathogenesis of C. lactucae-sativa on lettuce after plasma treatments for 5 min was examined by spraying an inoculation of the treated conidia on lettuce. The results showed that all three plasmas reduced the disease incidence and severity compared to the non-treated control. Therefore, the non-thermal atmospheric pressure GA, TC and DBD plasmas have antifungal potential for the inactivation of C. lactucae-sativa, making them an interesting novel technology for plant disease control.

This study analyzed the effect of combined phosphine (PH3) fumigation and low-temperature treatment on the control of Drosophila suzukii. In the low-temperature, single-treatment experiment, there was no significant difference in insecticidal activity between 1 °C and 5 °C except in D. suzukii adults. Adults showed 98.0% mortality after exposure to 1 °C for 7 d. Regarding fumigation treatment with PH3 alone, adults were the most susceptible, and pupae had the highest tolerance. Combined low-temperature treatment and fumigation showed a synergistic effect, except in the egg stage, and showed slight synergistic effects in larvae and pupae regardless of the combined treatment order. In pupae, the combination group exposed to 1 °C for 24 h after exposure to PH3 for 4 h had the lowest LCT99 value, at 10.49 mg·h/L. The sorption rate of PH3 on grapes decreased to 85.49% after 4 h of exposure, with a 15% loading ratio (w/v), and there was no significant difference in various criteria of phytotoxicity in exposed grapes compared to control, even after 14 d of combined treatment. Therefore, this study indicates that combined PH3 fumigation and low-temperature treatment could be useful in D. suzukii control. Full article
