    Abstract Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is the major invasive pest of small, soft-skinned and stone fruits, with a wide range of hosts. This study aims to test the susceptibility of this insect to entomopathogenic nematodes (EPNs) and their efficacy on infested fruits from first instar larvae to adult emergence. Drosophila suzukii and D. melanogaster (Meigen) (Diptera: Drosophilidae) were susceptible to Steinernema carpocapsae (Weiser) (Rhabditida: Steinernematidae), S. feltiae (Filipjev) (Rhabditida: Steinernematidae), Steinernema sp. (glaseri group) (Filipjev) (Rhabditida: Steinernematidae) and Heterorhabditis bacteriophora (Poinar) (Rhabditida: Heterorhabditidae) on two substrates (filter paper and agar). The greater efficacy against D. suzukii was achieved by S. feltiae and S. carpocapsae (94 and 84%, respectively) with equal efficacy than that obtained using D. melanogaster as host (93.37 and 92.88%, respectively). The EPNs infected and could reproduce inside D. suzukii larvae. In contrast, pupae of both species were not infected by them. Nematodes proved to be able to reduce adult emergence of D. suzukii (up to 35% by S. feltiae) on strawberry fruit under laboratory conditions. These results show that D. suzukii is as susceptible as D. melanogaster to EPNs, confirming the potential of these nematodes as biological control agents against this important pest.

    Abstract Entomopathogenic nematodes have been proposed as biological agents for the control of Drosophila suzukii, an invasive pest of small-stone and soft-skinned fruits. Larvae of the fly are susceptible to Steinernema carpocapsae infection but the reaction of immune defenses of the host are unknown. To determine the immune response, larvae were infected with S. carpocapsae and Xenorhabdus nematophila to evaluate the effector mechanisms of both humoral and cellular processes. The symbiont bacteria presented an inhibitory effect on the phenoloxidase cascade with a low level of melanization. Besides, X. nematophila activated the synthesis of putative antimicrobial peptides on the hemolymph of infected larvae. However, those peptides presented a lower antimicrobial activity compared to hemolymph from larvae infected with non-symbiont bacteria. Xenorhabdus nematophila avoided also the phagocytosis response of hemocytes. During in vitro and in vivo assays, S. carpocapsae was not encapsulated by cells, unless the cuticle was damaged with a lipase-treatment. Hemocyte counts confirmed differentiation of lamellocytes in the early phase of infection despite the unrecognition of the nematodes. Both X. nematophila and S. carpocapsae avoided the cellular defenses of D. suzukii larvae and depressed the humoral response. These results confirmed the potential of entomopathogenic nematodes to control D. suzukii.

    Abstract Drosophila suzukii is a global invasive pest of soft-skinned and small stone fruits. Fly larvae fall from fruit to the soil to pupate, after which time adults emerge. Biological control of D. suzukii larvae with entomopathogenic nematodes has been reported in previous studies with positive results, but susceptibility of adults has still not been evaluated. In this study, the susceptibility of mature adults to Heterorhabditis bacteriophora, Steinernema feltiae and S. carpocapsae was tested. We also evaluated the infection and dispersion of adults after emerging from soil treated with S. carpocapsae. The results showed that 65% of mature adults were infected with S. carpocapsae while the other nematode treatments barely reached 4% infection. This nematode was also able to reproduce inside the D. suzukii fly. When adults emerged from treated soil, S. carpocapsae infection reached 89%. The results of the dispersion assay showed that 21.4% of nematode-infected adults could fly. These results showed the potential of S. carpocapsae applications to soil in order to control adult emergence of D. suzukii.

    Abstract Entomopathogenic nematodes (EPNs) have been recently tested against target pests located on crop foliage with encouraging results. In these orchard environments, predator and parasitoid insects (natural enemies) are commonly released. However, the possible effect between these biological control agents has barely been approached. The aim of this study is to investigate the survival of four predator and four parasitoid species commonly used in horticulture exposed to EPNs under laboratory conditions. A first assay was done in Petri dishes with a dose of 100 IJs cm-2 of three different EPNs treatments separately. The results showed no effect of Heterorhabditis bacteriophora treatment on insect survival for 48 hours. Moreover, natural enemies registered a survival rate of over 75% with Steinernema feltiae treatment. These two EPNs were considered harmless according to the IOBC classification for side effects. In Steinernema carpocapsae treatment, parasitoids and predator nymphs had a survival rate of up to 76% while, in adult predators, survival ranged from 14% to 100%. Nematode infection and entry were also evaluated. The second assay tested the compatibility of insects with S. carpocapsae under more realistic conditions using a foliar application of 4000 IJs ml-1 on tomato plants. No insect species presented differences in survival between nematode and control treatments. The evaluation of EPN persistence showed that only half of the nematodes applied were still alive after seven hours. The three EPNs proved to be harmless to the natural enemies tested, with the discontinuous contact that a plant pot experiment involves. These results showed good compatibility between the natural enemies and EPNs tested, which should be confirmed in field conditions.

    Abstract The life-history traits of long-lived benthic littoral invertebrates remain poorly understood. In this study, we analysed patterns of growth in three abundant sublittoral sponges from the western Mediterranean Sea, chosen for their close phylogenetic relatedness, sympatric distribution, and contrasting amounts of photosymbionts: high in Ircinia fasciculata, lower in I. variabilis, and absent in I. oros. Sponge area, perimeter, number of oscula, and epibiont abundance were quantified from in situ digital images taken monthly for 1.5� years and volumetric growth rates were calculated from empirical area–volume relationships. Volumetric growth rates were different among species and coherent with the photosymbiont abundance: high in I. fasciculata (40.03� ±� 4.81� %� year⁻¹, mean� ±� SE), low in I. variabilis (5.65� ±� 6.11� % year⁻¹), and almost nil in I. oros (−0.04� ±� 3.02� % year⁻¹). Furthermore, a marked seasonality was observed in the first two species, with greater growth during the warm season. The high growth rates of I. fasciculata were likely fuelled by symbiont-derived photosynthates and required to compete in the well-lit, algal-dominated habitats this species prefers. In contrast, I. variabilis and I. oros tended to dwell in shaded habitats, where competition from slow-growing invertebrates is intense, and featured lower growth rates. The flattened morphology and lower circularity of I. variabilis indicates a capacity for adaptation to any space that is freed, while I. oros had less oscula and was more massive and circular, suggesting a strategy of passive occupation and minimisation of biological interactions. The results show that even congeneric species living sympatrically can achieve important biomass using different growth and substrate occupation strategies.
