Abstract

The aim of our study was to verify the effect on plant growth and biomass production of a new olive mill by-products named "Patè Olive Cake" (POC) generated by a multi-phase decanter (MPD) technology. POC is an olive mill by-product consisting of olive pulp, olive skin and vegetative water. The POC was treated with Eco-sustainable Separation and Extraction Technologies according to the methods developed and standardized by the ENEA Casaccia Research Center. In CREA Research Center for Agriculture and Environment (CREA-AA), methodologies and measurement protocols were applied both for the evaluation of different fractions of POC through biological laboratory assays to highlight their nutritional, biostimulant and toxic properties and trough experimental pot tests for the evaluation for agronomic use, from the perspective of the circular economy. Several studies have been carried out on the effects of oil mill products on the biological fertility of the soil but not on the POC. In the present work the first results obtained are reported and discussed for the adoption of protocols for the evaluation of different POC fractions through laboratory bioassays. This study was conducted within the Lazio Innova ABASA project, CUP B81G18000770002 (Agricultural By-products into valuable Assets for Sustainable Agriculture). [ABSTRACT FROM AUTHOR]

Abstract

In accordance with the Directive 2009/128/EC, the spreading of biological methods based on the sustainable use of pesticides is one of the main objective aimed at limiting the risks caused by the use of pesticides on environment and health. Plant extracts offer significant advantages in terms of sustainable agriculture and represent a feasible alternative against infestant weeds and pests for disease control of crops. Garlic (Allium sativum L.) is known for its stimulating properties on plant growth and also protects plants due to its bactericidal and fungicidal activity. In this study, the antioxidant properties of aqueous extracts of garlic were evaluated by DPPH method, for the ability to provide stress resistance in plants. Moreovere, the bio-stimulant and repellent effect of 1 % (w/v) aqueous extract was evaluated on plants of zucchini (Cucurbita pepo L.) in an open field test, under the spontaneous attack of parasites and pathogens. The vegetative conditions of plants were assessed by measuring the chlorophyll content in vivo using the fluorimeter SPAD 5200. To evaluate the antioxidant properties of fruits, generallly stimulated by abiotic environmental stress, we determined the antioxidant activity on zucchini harvested, using the same DPPH method. The results showed a higher fruit yield in treated plants due to higher vegetative vigour, higher chlorophyll content in their leaves and better flower induction compared to control plants. The zucchini plants seemed to have taken advantage from the repellent effect against insect vectors and the preventive effect of garlic extract used. Moreover we found that zucchini fruits had lower antioxidant activity in treated plants than in control plants, due to their better physiologic conditions. The introduction of plant extracts to replace conventional chemicals, could provide significant benefits on the environment and human health. [ABSTRACT FROM AUTHOR]

22. Macro-moths as possible assessment endpoints for non-target effects of Bt-maize pollen: a faunistic study in three Italian protected areas.

Abstract

Lepidoptera are the phytophagous group most at risk of impact by insect-resistant genetically modified (GM) plants since most of these crops have been developed to express toxins to specifically target lepidopteran pests. In the case of Bt-maize cultivation, pollen grains released by GM plants could dust larval host plants growing inside or nearby maize fields, thus leading to the exposure of caterpillars to the Cry toxins. This way of exposure has been studied mainly for butterflies, whereas moths, in spite of their great diversity and abundance, were rarely considered. To evaluate the potential exposure of moth species to maize pollen in absence of Cry-expressing plants, macro-moths were sampled by means of light traps in three protected areas of Northern, Central and Southern Italy where conventional maize is among the main crops. Light traps were activated in two consecutive years (2010- 11) from the beginning of June to the end of July, a period that encompasses the anthesis of most maize cultivars grown in Italy. Overall, 11446 individuals belonging to 201 species and nine families were collected. Given that larvae of several sampled species are likely to match the criteria of potential exposure to maize pollen and susceptibility to Cry toxins, macro-moths might be considered among the potential assessment endpoints for environmental risk assessment of GM plants, especially in the vicinity of protected areas.

Abstract

Ladybird beetles (Coleoptera Coccinellidae) are important predators of aphids and other crop pests, and there is great interest in their conservation in agroecosystems. Bt-maize, genetically engineered to express insecticidal Cry proteins, is regarded as a taxon-specific way of controlling pests, but some concerns have been raised about the possibility of unintended negative effects on non-target organisms, including coccinellids. One of the possible routes of exposure of ladybird beetles to Cry toxins is by feeding on maize pollen, as for many species pollen is an important integrative food source. In this study, coccinellid adults were sampled by sweep netting in Ecological Compensation Areas (ECAs) in three sites of Northern and Central Italy, where conventional maize cultivars are grown (Bt-maize is currently forbidden for commercial cultivation in Italy). The coccinellid communities were sampled during and around the typical flowering periods of maize in order to check their diversity and their overlap with pollen shedding. A total of 11 species were recorded. Hippodamia variegata (Goeze), Coccinella septempunctata L. and the exotic Harmonia axyridis (Pallas) were the most abundant species in Northern Italy, whereas Tytthaspis sedecimpunctata (L.) and Coccinula quatuordecimpustulata (L.) were dominant in Central Italy. The potential exposure to maize pollen was different in the two areas, since in Northern Italy the maize flowering coincided with a period of high coccinellid activity in the field, whereas in Central Italy the ladybird population peaks occurred roughly one month earlier than the anthesis. The collected data might be useful for exposure characterization of ladybird beetles in a possible future scenario of Bt-maize cropping in the studied areas.
