    ABSTRACT: Sublethal effects of NeemAzal®-T/S (1 % azadirachtin A) on female cockchafers were studied in two experiments with caged beetles. The beetles were collected in early spring whilst leaving the soil after hibernation. At that time, they had not fed before and they were virgin. The beetles were kept singly in plastic boxes and provided with treated leaves at different stages of egg maturation. The amount of food consumed and the progression of body weight were recorded daily, whereas the state of oogenesis was surveyed at defined intervals. It was shown that food consumption, body weight development and egg maturation were affected by the uptake of azadirachtin-treated plant material compared to beetles from control groups. In no-choice experiments, azadirachtin-treated leaves were accepted readily and feeding was reduced by 60–70 % compared to females fed with untreated foliage. Recovery by feeding on untreated leaves after the uptake of contaminated foliage was either not evident or at a very low level. Moreover, egg maturation was interrupted when females were fed with azadirachtin-treated leaves during the process of oogenesis. If egg maturation was accomplished at the time of first uptake of azadirachtin-treated plant material, caged females were able to lay as many eggs as females from the control group, the egg hatching rate was not affected, and there were no signs of morphological malformations in the freshly hatched L1-larvae.

    ABSTRACT: Seed treatments with essential oils (from savory and thyme) and biocontrol agents (Pseudomonas spp. and Fusarium oxysporum) have been evaluated in vivo after dry hot air treatments against Fusarium oxysporum f. sp. basilici on basil seeds. The savory and thyme essential oils showed a significant pathogen control activity because of their innate antifungal activity and because of the seed application method, but the dry hot pre-treatment did not show any obvious effect on the performance of the essential oil treatments. The dry heat treatment improved the Pseudomonas seed dressing effect against F.oxysporum f. sp. basilici, and showed important reductions in plant infection and the disease index on the treated seed plants, without any negative effect on seed germination. However, the pathogen control provided by the heat treatments combined with the application of the biocontrol agents never reached the same performance as the chemical treatments considered as the reference. Thus, short dry heat treatments on basil seeds have been shown to be a valid but complementary seed disinfection method against Fusarium wilt.

    ABSTRACT: The chive maggot, Bradysia odoriphaga (Diptera: Sciaridae), is the major pest that damages Chinese chive in China. Benzothiazole is a volatile compound derived from microorganisms secondary metabolites and has fumigant activity against B. odoriphaga. However, the sublethal effects of benzothiazole need to be evaluated before registration and application, to fully understand the potential for control of this pest. Laboratory investigations showed that sublethal concentrations (LC10 and LC30) of benzothiazole decreased the survival rate and the fecundity of B. odoriphaga compared with control. However, the developmental times of eggs, larvae and pupae, and the total preoviposition period were prolonged. Additionally, population parameters were significantly affected in the treated groups. The intrinsic rate of increase (r m ) decreased to 0.1391 (LC10) and 0.1140 (LC30) day-1 compared with the control population (0.1589 day-1). The net reproductive rate (R 0 ) in the control was 54.39 offspring/individual, whereas the R 0 decreased to 41.80 and 25.08 offspring/individual in the LC10 and LC30 treatments, respectively. This study demonstrated that sublethal concentrations of benzothiazole adversely affected the developmental time, fecundity and life table parameters of B. odoriphaga. Therefore, benzothiazole has the potential to be exploited as a natural derived fumigant for the control of this pest. Graphical abstract Scheme about the life table experimental setup

    ABSTRACT: The infection process was explored by light and electron microscopy techniques, as well as bioassays assessing phytotoxins and cell wall-degrading enzymes. We found that germ tubes of asparagus stem blight fungus were produced at 0-24 h after culture on dextrose agarose medium, and mycelia were formed at 24-48 h. Then, mycelia grew and spread continuously, making incursions into host tissues after 4 days. The conidial fructification began to form after 8 days. Subsequently, pycnidia were produced after about 12 days, with conidia released after about 16 days. Interestingly, through culture, extraction and bioassay of phytotoxin culture filtrates, no overt damage of asparagus tissues was found. As for cell wall-degrading enzymes, PG showed the highest activity, followed by Cx and PMG; PGTE and PMTE displayed the lowest activities. Finally, we demonstrated that permeable reducing sugars and relative electric conductivity in the culture increased after incubation in cell wall-degrading enzyme solutions, in an enzyme concentration dependent manner.

    ABSTRACT: The quick decline syndrome of olive (OQDS) is a disease that appeared all of a sudden some years ago in a restricted area near the city of Gallipoli (Ionian coast of the Salento peninsula, southern-east Italy) and began spreading through the heavily olive-grown countryside of lower Salento. Xylella fastidiosa, a quarantine pathogen of American origin previously undetected in the European Union territory, except for two unconfirmed records from Kosovo and Turkey, proved to be consistently associated with symptomatic trees. X. fastidiosa is a Gram-negative bacterium that invades and multiplies in the xylem vessels of infected hosts, from which it is acquired by xylem-feeding insect vectors (belonging to Auchenorrhyncha, including cicadellids sharpshooter leafhoppers group, Cicadellidae, Cicadellinae), and aphrophorids (cercopids and spittlebugs, Cercopidae) and transferred to other plants. The Salentian strain of X. fastidiosa, denoted CoDiRO, was obtained in axenic culture. Its genome, a DNA molecule ca. 2.5 million base-pairs in size, was sequenced and identified as a genotype of X. fastidiosa subsp. pauca molecularly identical to an isolate of the same subspecies from Costa Rica. In nature, strain CoDiRO infects a number of woody and shrubby hosts but not grapevines and citrus and is mainly transmitted by Philaenus spumarius (meadow spittlebug), a froghopper quite common in the Salento area where it thrives primarily on olive. Since OQDS eradication and sanitation of infected olives are unfeasible, strategies have been envisaged for restraining the spread of the pathogen and its vector within the boundaries of the currently infected zone.

    ABSTRACT: The combined effects of soil solarization and application of compost of various maturity levels upon soil microbial activity were studied under field conditions during 2010–2012. Eight treatments were divided into solarized and non-solarized treatments, and each was either non-amended or annually amended with compost at 6 kg (DW) m-2. The composts were mature, partially mature, or immature. In all three tested parameters of microbial activity (respiration rate, heat output, and dehydrogenase activity) the immature compost showed higher activity than the other compost types. Soil samples were collected weekly in order to assess microbial activity, which was evaluated from measurements of soil respiration rate, heat output, and dehydrogenase activity. Significant and year-to-year reproducible differences in all three parameters were observed between soils amended with the three compost types. Some residual (carry-over) effects of previous-year treatments were obtained. Microbial activity decreased in both solarized and non-solarized treatments during the experimental period, probably because of increasing summer temperatures, but the decline was sharper in the solarized treatments probably due to oxygen deficiency under the tarp. Significantly higher activity was found in the treatments amended with the immature compost, both in the solarized and non-solarized treatments. This could be a result of the high level of dissolved organic matter in the immature compost, which enhanced microbial activity.

    ABSTRACT: Survival of entomopathogenic nematodes (EPNs) in soils is attributed to their entering a dormant state—anhydrobiosis—as soil moisture decreases, but EPNs with poor desiccation tolerance and low anhydrobiotic capabilities may practice desiccation avoidance. We compared the effect of soil moisture gradient on downward movement of the highly desiccation-tolerant Steinernema carpocapsae and the poorly desiccation-tolerant Heterorhabditis bacteriophora. Infective juveniles (IJs) were applied to the surface of moist (11–13% w/w moisture) sandy soil in buckets. Nematode distribution was monitored at different depths 3, 14 and 28 days after application. In uncovered buckets, soil moisture decreased to 1% in the upper 5-cm layer after 28 days. H. bacteriophora IJs abandoned the upper soil layers as dryness intensified with >80% found in the bottom (20–25 cm) layer. In contrast, >70% S. carpocapsae IJs remained in the upper layer. In covered buckets, with 10% moisture throughout the experiment, heterorhabditid IJs were equally distributed between the 10–15 cm and 20–25 cm layers; only 7% remained in the upper layer. Again, >70% S. carpocapsae IJs remained in the upper layer throughout. Soil type influenced H. bacteriophora IJs' downward migration. In sandy and sandy loam soils, with rapid evaporation, >80% IJs were in the bottom layer 14 and 28 days after application. In the loam soil, with higher moisture retention, >75% IJs remained in the 10–15 cm layer and <20% migrated to the bottom. Results provide initial evidence of a possible stress-avoidance strategy in H. bacteriophora under natural conditions.
