Special Issue Information

Dear Colleagues,

During the growing period, horticultural crops are threatened by a wide range of invertebrate pests (especially insects, mites, nematodes, molluscs) and pathogens (fungi, bacteria, viruses), which can cause giant economic losses. With the increase in the number and size of protected cultivation areas, pest pressure increases, and becomes more complex. In recent years, the emergence of new invasive pathogens and pests, increasing problem of pesticide resistance, and the need for the sustainable use of pesticides are the main concerns of plant protection.

Nowadays, there is a great need to develop rapid and accurate diagnostic methods, monitoring and forecasting options and models, and optimize disease and pest management strategies by adopting novel, integrated, and sustainable control methods.

This Special Issue entitled “New Insights into Pest Management in Horticultural Production” cordially invites experts from around the world to submit scientific materials (original research, reviews, and opinions) covering all aspects of horticultural crop protection, such as the findings on newly establishing or invading diseases and pests; dispersal of invasive species; pesticide resistance; innovative monitoring approaches, models, and techniques; advances in chemical/biological methods of plant protection; methods to induce and utilize crop resistance. Particularly welcome are studies in which the efficacy of any of the approaches mentioned above have been not only designed but also tested in the field.

Tetranychus urticae is a severe threat and a major source of yield loss in some agricultural and horticultural crops and it is also as a vector for several viruses. The number of active substances used against the pest is limited. Therefore, there is a continuous need for new active substances. Recently, lithium salts have been shown to be one of the most promising potential alternatives to control Varroa destructor; an apicultural mite pest. Based on this, we aimed to test whether the efficacy of lithium chloride extends to other agricultural mite pests, such as the two-spotted spider mite. In the present pilot study, we report for the first time that the efficacy of lithium chloride is extended to the two-spotted spider mite. Additionally, this is the first report on the acaricidal effectiveness of lithium on a plant mite pest. In the present study, we report three different concentrations that bear 100% mortality at concentrations of 5.52 M, 2.76 M, and 1.38 M. The symptoms caused were similar and followed the same sequence compared to those observed on animal parasites such as V. destructor and Dermanyssus gallinae. Full article

Top rot is a new fungal fruit disease in Rosa roxburghii production regions of southwest China. In this study, the pathogen of top rot disease in R. roxburghii fruits was firstly identified as Colletotrichum fructicola CXCDF-3 based on the pathogenicity, morphology, and multigene phylogenetic analysis. The biological property test results indicated that the optimal growth conditions of C. fructicola CXCDF-3 were 25 °C, pH 6.0~8.0, full light or darkness, D-(+) maltose, peptone, and PDA medium. Moreover, difenoconazole, tebuconazole, azoxystrobin, prothioconazole, thiophanate-methyl, prochloraz, carbendazim, and cyprodinil displayed superior toxicity activities to C. fructicola CXCDF-3 with EC50 values of 0.26, 0.64, 0.99, 2.15, 4.64, 4.89, 7.27, and 7.73 mg L−1, respectively. The field control efficacies of 80% tebuconazole water-dispersible granule (WG) 6000-fold liquid, 10% difenoconazole WG 5000-fold liquid, and 250 g/L azoxystrobin emulsifiable concentrate (SC) 1000-fold liquid against top rot disease of R. roxburghii fruits were 85.44%, 84.47%, and 83.50%, respectively. This study reports for the first time that the novel top rot disease in R. roxburghii is caused by C. fructicola and highlights that 80% tebuconazole WG, 10% difenoconazole WG, and 250 g/L azoxystrobin SC could be recommended for controlling top rot disease.

Biofumigant and crop sequencing are effective and safe control system activators that maintain soil fertility and reduce pest populations. The study goals were to find new pesticide-free therapies for root-knot nematode management on cucumbers to maintain high yields and protect the environment and human health. In 2018 and 2019, the research employed a fully randomized block design under field conditions with five treatments and control: two bio- fumigants, cultivation of cucumber after broccoli plantlets incorporation (BPI) and radish plantlets incorporation (RPI), two crop sequence treatments (cultivation after broccoli (BCS) and radish (RCS), and nematicide treatment). Cucumber cultivation after BPI treatment exhibited the best horticultural traits, which reflected positively on early and total productivity. The increased yield was gained by suppressing all nematode parameters, the number of nematode larvae, galls, and egg masses, as well as egg hatching reduction. The most effective biocides, total phenols, myrosinase activity, total glucosinolates (GSLs), and isothiocyanates (ITCs) in brassica crops were estimated for their pesticide properties. The highest amount was released with BPI treatment, compared to adult plants and radish in its two stages. The bio-managed treatments revealed superior effectiveness compared to nematicide application and control to suppress the nematode population while enhancing cucumber growth and production.

Bois noir, an economically important disease of grapevine yellows that causes significant economic losses in wine production, is associated with ‘Candidatus Phytoplasma solani’ and transmitted to grapevines by cixiids Hyalesthes obsoletus and Reptalus panzeri. Polyphagous planthopper Dictyophara europaea, commonly found in natural habitats, harbors phytoplasmas from distinct groups and is an alternative vector in the open epidemiological cycles of the Flavescence dorée phytoplasma in grapevine in European vineyards. This study addresses the role of D. europaea in the transmission cycle(s) of ‘Ca. P. solani’ among wild habitats, natural reservoir plants, and the vineyard agroecosystem using MLSA and transmission trials with naturally infected adults to grapevine and Catharanthus roseus. The infection rates of D. europaea ranged from 7% to 13% in diverse locations, while reservoir herbaceous plants were infected in the amount of 29%. A total of 13 CaPsol MLSA genotypes were detected in D. europaea (7) and plants (8). Nine of them corresponded to previously identified genotypes. Two new genotypes were found in D. europaea (tuf-b1/S1/V14/Rqg50-sv1 and tuf-b1/S18/V14/Rqg50-sv1) and one in Convolvulus arvensis (tuf-b1/S1/V2-TA/Rqg31-sv1), whereas one was shared by two hosts, Crepis foetida and Daucus carota (tuf-b1/S1/V2-TA/STOL-sv1). Naturally infected D. europaea successfully transmitted the tuf-b1/S1/V2-TA/STOL type to five grapevines and six periwinkles, tuf-b1/S1/V2-TA/Rqg31 to one grapevine, and tuf-b1/S1/V2-TA/Rqg50 to one periwinkle, indicating that D. europaea is an intermediate vector in CaPsol epidemiological cycles.

The control strategies for the olive crop key pest, Bactrocera oleae, involve synthetic chemical insecticides and few eco-sustainable alternatives, such as ovideterrents and lures. In the last few decades, the interest concerning the formulation of botanical based biopesticides increased, but little research investigated the suitability of these approaches for B. oleae control. This research aimed to investigate the residual contact toxicity and the oviposition deterrence of three essential oil (EO)-based nano-emulsions (Pimpinella anisum, Foeniculum vulgare, Mentha × piperita) against B. oleae adult flies. All the nano-emulsions possessed optimal physical characteristics, with droplets dimensions ranging from 115 to 152 nm and low PDI values (<0.2), even after 1 year of storage. Although no notable residual contact toxicity was noted, all the tested formulations reduced the number of oviposition puncture in no-choice tests (percent repellence: mint < fennel < anise). In choice trials, olives treated with fennel and anise EO-formulations at the highest concentration (7.5%, 75 g of EO/L) were less attractive respect to control fruits and a significant reduction of olive punctures was recorded. Nano-biopesticides are promising eco-friendly tools to integrate B. oleae pest management programs and to reduce the use of harmful conventional active ingredients. Full article

Rhagoletis batava (Diptera: Tephritidae), is the most important pest of Hippophae rhamnoides fruits. For detection and monitoring of R. batava, traps supplied with nonspecific attractants are used. Thus, new, more specific attractants for environment-friendly pest control are needed. Such attractants could be fruit-related semiochemicals that are involved in the host location by flies. Behavioural Y-olfactometer tests revealed that R. batava males were attracted to ripe fruit odour, while females preferred unripe and semi-ripe fruits. Thermal desorption gas chromatography-mass spectrometry (GC-MS) analysis revealed substantial quantitative and qualitative changes in volatiles between unripe and ripe fruits. In the unripe fruit emission, 41 volatile compounds were isolated, whereas 64 compounds were sampled from the ripe fruits. The total amount of volatiles increased five times during the fruit ripening. Gas chromatography-electroantennogram detection (GC-EAD) and GC-MS analyses of the fruit headspace volatiles revealed at least 26 compounds in unripe and 27 compounds in ripe fruits eliciting antennal responses of R. batava for both sexes. The fruits of these two ripening stages differed qualitatively in the single EAD-active compound only, i.e., 3-methylbutyl 2-methylpropionate. Esters were the most abundant volatiles, composing 84% and 93% of EAD-active compounds in the emissions of unripe and ripe fruits, respectively. Based on the persistent EAG responses, 17 compounds were selected as the most promising candidates for kairomone attractants of the sea buckthorn pest R. batava. Full article

The state-of-the-art technique to control slug pests in agriculture is the spreading of slug pellets. This method has some downsides, because slug pellets also harm beneficials and often fail because their efficiency depends on the prevailing weather conditions. This study is part of a research project which is developing a pest control robot to monitor the field, detect slugs, and eliminate them. Robots represent a promising alternative to slug pellets. They work independent of weather conditions and can distinguish between pests and beneficials. As a prerequisite, a robot must be able to reliably identify slugs irrespective of the characteristics of the surrounding conditions. In this context, the utilization of computer vision and image analysis methods are challenging, because slugs look very similar to the soil, particularly in color images. Therefore, the goal of this study was to develop an optical filter-based system that distinguishes between slugs and soil. In this context, the spectral characteristics of both slugs and soil in the visible and visible near-infrared (VNIR) wavebands were measured. Conspicuous maxima followed by conspicuous local minima were found for the reflection spectra of slugs in the near infrared range from 850 nm to 990 nm]. Thus, this enabled differentiation between slugs and soils; soils showed a monotonic increase in the intensity of the relative reflection for this wavelength. The extrema determined in the reflection spectra of slugs were used to develop and set up a slug detector device consisting of a monochromatic camera, a filter changer and two narrow bandpass filters with nominal wavelengths of 925 nm and 975 nm. The developed optical system takes two photographs of the target area at night. By subtracting the pixel values of the images, the slugs are highlighted, and the soil is removed in the image due to the properties of the reflection spectra of soils and slugs. In the resulting image, the pixels of slugs were, on average, 12.4 times brighter than pixels of soil. This enabled the detection of slugs by a threshold method. Full article
