Special Issue Information

Dear Colleagues,

Climate change has substantially impacted horticulture, causing a reduction in production and sometimes making harvests unviable. Furthermore, arthropod pests cause damage to crops and increase production costs. The abusive and indiscriminate use of synthetic chemical insecticides leads to environmental contamination, selection of resistant arthropod populations, and toxic effects on non-target organisms. The damage caused by arthropods in the post-harvest period must also be considered. Given the above, defining advanced strategies for controlling arthropod pests is necessary.

The purpose of this Special Issue, entitled “Advanced Strategies for Arthropod Pest Control in Horticultural Systems”, is to contribute to disseminating new knowledge and results developed by researchers worldwide. Further contributions are expected regarding good agricultural practices (GAPs); use of bioinputs; semiochemicals; biological control; selectivity and/or compatibility of pesticides for non-target organisms; botanical insecticides; studies involving structure/activity and biochemical mode of action of pesticides; mode of action of new compounds; integrated pest management (IPM); and resistance of pests and other essential themes for advancing the state of the art. Research papers on products of uncertain chemical composition, for example, crude extracts and essential oils with incomplete chemical descriptions, are not accepted for review.

Bitter Hawkesbury watermelon (BHW) Citrullus lanatus (Thunb.) Matsum. and Nakai (syn. Citrullus vulgaris Schad) contain high concentrations of cucurbitacin-E-glycoside (CEG), a compound that acts as an arrestant and feeding stimulant for diabroticine leaf beetles that are corn (maize) and cucurbit pests. Juice from BHW is used as feedstock to produce an insecticide synergist for improved chemical control of pests in cucurbit cropping systems. A positive linear relationship was observed between the CEG concentration of parent and offspring grown in open-pollinated field plots. However, subsequent experiments that explored the influence of parent and fruit maturity on CEG concentration did not confirm a relationship between accumulation patterns among offspring of half-sibling families. An effect of maturity was observed in that earlier harvested fruit had greater CEG concentrations than ripe or overripe fruit. In a field study, CIDETRAK L (active ingredient is BHW juice) was mixed with commonly used insecticides to enhance behavioral control of striped cucumber beetle Acalymma vittatum (F.) and squash vine borer Melittia cucurbitae (Harris). Equivalent control of A. vittatum and M. cucurbitae was observed on zucchini when treated with foliar applications of spinosad, acetamiprid, or lambda-cyhalothrin versus ground applications of the same products mixed with CIDETRAK L.

Phenology models are widely used in Decision Support Systems to predict the phenology of pests. Grapholita molesta (Busck) (Lepidoptera: Tortricidae), a polyphagous pest, has a high prevalence in apple trees (Malus domestica Borkh.) (Rosales: Rosaceae) in certain areas, despite the fact that apple trees are considered secondary hosts. Its natural behavior of feeding inside plant tissue at the larval stage makes monitoring and planning methods of control critical for Integrated Pest Management. The development times and survival rates of two field populations of G. molesta larvae on apple cultivars ‘Gala’, ‘Golden’, and ‘Fuji’ were determined under different temperature (constant versus field fluctuation) and feeding conditions (diet versus apples attached to the tree and detached from the tree). The results showed that G. molesta fitness in apples is affected by fluctuating temperature regimes in the field, the condition of the fruit, whether or not the fruit is attached to the tree, and the cultivar. The temperature was the main cause of the differences in the studied parameters. Larvae developme–nt time was delayed due to fluctuating field temperatures. Larvae had a shorter development time in fruits detached from the tree compared to attached fruits, and apple cultivars influenced development time in both laboratory and field conditions, with the ‘Golden’ cultivar having better fitness and a higher rate of larvae survival in the fruits attached to the tree. These factors need to be considered to properly adjust the phenology models and improve the Integrated Pest Management system of apples. Full article

The spotted wing drosophila, Drosophila suzukii (Matsumura), is currently distributed in the main soft-skinned fruits production areas in China and 59 other countries, presenting a significant threat to importing nations. Optimal phytosanitary treatments, including fumigation, irradiation, and cold treatment, have been developed to prevent the international movement of this invasive fly. To determine the most cold-tolerant stage and facilitate the development of the technical schedules requested by the Technical Panel on Phytosanitary Treatment (TPPT), cold treatments of D. suzukii immature stages in ‘Red Globe’ grapes were conducted. Dose–mortality data at 0 °C and 2 °C from repeated trials were subjected to analysis of covariance, linear regression, and probit analysis. Results identified 3 d old pupae as the most cold-tolerant stage, followed by 1 d old pupae, 4 d old larvae, and 6 h old eggs with similar tolerance. The 2 d old larvae were the most sensitive stage. In subsequent confirmatory tests, 3 d old pupae were subjected to cold treatment at 0 °C for 9 and 10 days, and at 2 °C for 10 and 12 days, based on the probit estimation of the probit-9 value. No adult emergence occurred in the confirmatory tests except for one deformed adult from a 2 °C 10 d treatment. Therefore, the recommended treatment schedule requires fruit temperatures below 0.00 °C (or 1.62 °C) for no less than 10 (or 12) continuous days, with treatment efficacy not less than 99.9960% (or 99.9955%) at a 95% confidence level, respectively. These schedules are intended for submission to TPPT for the development of phytosanitary treatment standards. Full article

The diamondback moth, Plutella xylostella L., is a lepidopteran pest that damages various vegetable plants belonging to the genus Brassica worldwide. Various biological controls, such as parasitoid wasps, have been used to control this pest. Among these, Diadegma semiclausum and Diadegmafenestrale are widely used globally. In field-based biological control research, the investigation of the population dynamics of parasitoids and the rate of parasitism within the pest population is very important. However, achieving profundity in research is difficult when morphologically similar species coexist in the field. The morphological characteristics of D. semiclausum and D. fenestrale are very similar, and they both parasitize P. xylostella larvae. Therefore, to accurately identify these species, in this study, we developed a molecular diagnostic method by using loop-mediated isothermal amplification (LAMP). The mitochondrial genome of D. fenestrale and partial nucleotide sequences, including the ITS region of D. semiclausum, were analyzed for use as species diagnosis markers. The results showed that the homology of D. fenestrale to D. semiclausum was 94%, due to the excessively low homology of the D loop, but the actual homology was higher than 94%, particularly in the coding region. D. fenestrale species-specific primers for LAMP were designed based on the region encoding COX3, and the optimal diagnostic reaction condition for the four primers (F3, B3, FIP, and BIP) was 63 °C for 35 min. A species-specific primer capable of classifying D. semiclausum was developed based on the ITS2 region, and the optimal reaction condition for diagnosis was 63 °C for 40 min. Under optimal conditions for both species, upon addition of the loop primer LB, the reaction efficiency increased, and the reaction time was shortened by more than 5 min. The diagnostic limit concentration was up to 10 pg under both optimal conditions; therefore, it was possible to detect even very low concentrations. For both species, diagnosis was possible by using LAMP assay with a DNA-releasing technique, without a DNA extraction process, and by incubating a tissue sample or the homogenized whole body at 95 °C for 5 min. In the case of D. fenestrale, it was possible to diagnose the parasitoid in P. xylostella larvae. Therefore, the developed LAMP diagnostic method can be used in a variety of ways to determine whether P. xylostella has been parasitized in the process of field research and mass breeding, and to accurately distinguish the species that are parasitic to P. xylostella larvae. This LAMP-based diagnostic method can be applied to identify various parasitoids that are used for the biological control of P. xylostella. Full article
