The susceptibility of the newest and most used strawberry cultivars to the Spotted Wing Drosophila (SWD) in southwestern Spain was evaluated. Sixteen strawberry cultivarswere selected (‘Calderón’, ‘Calinda’, ‘Charlene’, ‘Flaminia’, ‘Flavia’, ‘Fortuna’, ‘Marisol’,‘Marquis’, ‘Melissa’, ‘Palmeritas’, ‘Petaluma’, ‘Plared0955’, ‘Primoris’, ‘Rábida’, ‘Rociera’and ‘Sabrina’) and no-choice tests were carried out under laboratory conditions. In addition, fruit weight, fruit firmness, °Brix, pH, protein content and total phenolic content were recorded in order to assess what influence these variables had on SWD infestation. The sixteen strawberry cultivars tested in this study were susceptible to SWD, although significant differences have been found among them. The mean number of emerged adults in ‘Calderon’ and ‘Plared0955’ were significantly higher than in the other tested cultivars. Significant differences in developmental time were also detected among these cultivars and both sexes but these were unrelated to the level of infestation. No correlation between fruit quality and chemical traits and infestation parameters was found. Our results detected significant differences in the susceptibility of strawberry cultivars in southwestern Spain to SWD; these may help to design IPM programs and to make recommendations for strawberry production, one of the most important crops in southern Europe.

New records of Oecanthus species (Orthoptera, Oecanthidae) in the Madeira archipelago

Journal of Orthoptera Research (2024)

Hugo Miguel Silva Laura Avivar‐Lozano Gonçalo Gomes Howon Rhee Thomas Dellinger

The Madeira and Porto Santo Islands have both witnessed substantial habitat loss since their initial colonization. Despite their small size and the degradation of their natural habitats, they harbor a rich diversity of terrestrial invertebrates, including a significant number of endemic species. While research on Orthoptera fauna has predominantly focused on the largest island of Madeira, the smaller island of Porto Santo has remained relatively understudied. Fieldwork on both islands has led to the discovery of Oecanthus dulcisonans Gorochov, 1993 in the Madeira archipelago (Porto Santo and Madeira) for the first time. This species was described based on specimens collected in Tenerife and the Arabian Peninsula. However, its distribution, which includes parts of Africa, Western Asia, and some localities in Southern Europe, remains poorly understood. Oecanthus dulcisonans is morphologically very similar to Oecanthus pellucens (Scopoli, 1763), the only species of this genus previously recorded for the island of Madeira. Due to this resemblance, doubts have arisen regarding which of these two species is present in Madeira. By examining new material of O. pellucens , we have confirmed the presence of this species on Madeira as well. These new findings highlight the fact that, for these species, the Madeira archipelago represents the western limit of their distributional ranges in the Palearctic region.

Three leafhoppers newly recorded from the European mainland (Hemiptera: Auchenorrhyncha: Cicadellidae), with notes on their habitats

Zootaxa (2024)

Laura Avivar‐Lozano Sergio Pérez‐Guerrero José María Molina Fábio de Barros Reis Dora Aguín‐Pombo

The leafhopper fauna of the Iberian Peninsula is the least studied in Europe. Recent surveys in agroecosystem areas of southern Spain, specifically in Andalusia, aimed to identify potential Auchenorrhyncha vectors of the bacterium Xylella fastidiosa. During these surveys, three previously unrecorded species of Cicadellidae belonging to the subfamily Deltocephalinae have been discovered. These newly recorded species are Balclutha incisa (Matsumura), Cicadulina (Cicadulina) bipunctata (Melichar), and Maiestas angustisecta (Linnavuori). Generally, these species were previously only known from American, African and eastern Palaearctic regions. This work is the first to record these species on the European mainland. Detailed descriptions of adult specimens have been provided, along with information on their current distribution and host plants. The potential role of these leafhoppers as potential vectors of plant pathogens is discussed, highlighting their importance in agroecosystems.

peaches) are the crops most susceptible to infestation.In Andalusia (southern Spain), D. suzukii was fi rst detected in 2012 in the province of Huelva.As over 80% of the berries in Spain are produced in Huelva, they are an important socio-economic driver in this region.Damage of around 80% of the strawberry crop, 100% of the cherry crop and 100% of organic crops were detected relatively shortly after D. suzukii arrived in Spain (Sorribas, 2013).In conventional farming D. suzukii is mainly chemically controlled in Europe using organophosphorates, pyrethroids and spinosyns.However, using these insecticides has consequences in terms of resistance (Bruck et al., 2011;Smirle et al., 2017;Gress & Zalom, 2019) and environmental pollution, is detrimental to benefi cial arthropods, incompatible with organic management and violates the MRL (maximum residue limit) zero tolerance policy in Laboratory evaluation of effects of powdered sulphur on the oviposition,

Short communication: Laboratory evaluation of nine highbush blueberry cultivars susceptibility to Drosophila suzukii (Matsumura, 1931) in the Southwestern Spain

Spanish Journal of Agricultural Research (2020)

José María Molina Laura Avivar‐Lozano Sergio Pérez‐Guerrero

Aim of study: To determine how susceptible the most used Southern highbush blueberry (SHB) cultivars were to the spotted wing Drosophila (SWD), Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) as well as those recently introduced to Southwestern Spain.Area of study: Southwestern Spain (Huelva province).Material and methods: Nine of the SHB cultivars which were recently introduced in Southwestern Spain and the most used ones were selected: ‘Arana’, ‘Camellia’, ‘Kirra’, ‘Mayra’, ‘Misty’, ‘O'Neal’, ‘Sharpblue’, ‘Star’ and ‘Ventura’. In order to determine how susceptible the cultivars were to SWD, no-choice tests were performed under laboratory conditions. In addition, berry size, berry firmness, ºBrix, and pH were recorded in order to assess what influence these variables had on oviposition preference by SWD.Main results: Mean clutch size and mean number of emerged adults in ‘Star’ were significantly higher than in the other tested cultivars. ‘Mayra’, ‘Camellia’ and ‘Ventura’ received the lower clutch sizes and mean number of emerged adults. Mean developmental time (egg to adult) differed significantly among tested cultivars and were highest in ‘Camellia’ than in the other tested cultivars. Only firmness and pH were correlated with SWD infestation as females tend to oviposit more eggs in softer fruits than in firmer fruits. Results also showed that a higher pH increased the emergence of adults and shortened the egg to adult developmental time.Research highlights: Our results showed significant differences in the susceptibility of SHB to SWD. This information may help design IPM programs and in making recommendations for blueberry crops as planting of low-chill cultivars expands.

The effectiveness of Chrysoperla carnea (Neuroptera: Chrysopidae) and Beauveria bassiana (Ascomycota: Hypocreales) as control agents of Neophilaenus campestris (Hemiptera: Aphrophoridae) a vector of Xylella fastidiosa

European Journal of Entomology (2023)

Laura Avivar‐Lozano José María Molina Sergio Pérez‐Guerrero

The effectiveness of two biological control agents, Chrysoperla carnea (Neuroptera: Chrysopidae) and the entomopathogenic fungus Beauveria bassiana (Ascomycota: Hypocreales) against nymphs and adults of Neophilaenus campestris (Hemiptera: Aphrophoridae) was determined under laboratory conditions. First, different nymphal stages of N. campestris were presented to different larval stages of C. carnea. Second, the effect of the foam produced by N. campestris nymphs on the larvae of C. carnea predation was evaluated. Finally, four concentrations of a wild strain of B. bassiana, BbGEp1, were sprayed on plants in order to determine their lethality for adults of N. campestris. Second and 3rd-instar larvae of green lacewing larvae are capable of capturing and killing 3rd and 5th-instar nymphs of N. campestris. The percentage of 3rd-instar lacewing larvae that killed nymphs was significantly higher than that were killed by second-instar larvae. Second-instar larvae killed significantly more 3rd-instar nymphs than 5th-instar nymphs. Third instar lacewing larvae killed an average (± SEM) of 1.50 ± 0.31 5th-instar nymphs and 2nd-instar larvae killed very few nymphs. Spittlebug foam reduced, but did not prevent predation. The lethality of the entomopathogenic B. bassiana BbGEp1 used against adults of N. campestris was characterized by an LC50 value of 1.61 × 106 conidia/mL and LT50 of 3.63 days at 1 × 107 conidia/mL. The present study provides new and valuable data on the activity of two promising biological control agents of vectors of the bacterium Xylella fastidiosa. Further research is needed to confirm the results presented here and on the cost effectiveness of using these control agents as alternatives to synthetic insecticides for preventing the further spread of X. fastidiosa in Europe.
