Effectiveness of mass trapping by bottle traps baited with salt sardines to control Bactrocera oleae (Gmelin)
2007
Various substances are known as attractants of tephritid flies; the putrescine and other compounds coming from animal decay have been positively tested for attraction of Bactrocera cucurbitae (Coquillett) and other tephritids. In Sicilian coastal areas, usually heavily infested by Bactrocera oleae (Gmelin), few organic farmers producing high quality olive oil apply mass trapping by using bottle traps baited with salt sardines. The aim of this paper is to test the effectiveness of this kind of mass trapping to control the olive fruit fly. In 2005 and 2006 mass trapping was tested in an organic olive grove (Cerasuola cultivar) located in Trapani. In 2005 two plots were delineated: 189 untreat…
Effects of Organic and Chemical N-fertilization on Yield and Morpho-biological Features in Coriander (Coriandrum sativum L.).
2009
Although MAPs are subjected to a growing interest (from growers, transformation industries, public and private institutions), a full introduction of such species into the Mediterranean cropping systems still needs the pointing out of many aspects. An important task concerns some aspects of cropping technique, whose definition could allow these crops to optimize the yields (both from the qualitative and the quantitative point of view), also allowing the best exploitation of land resources. One of the most crucial aspects is linked to plant fertilization, above all with Nitrogen. The trial that we report the results of has been performed in 2003- 04 and 2004-05 with the aim to study the effec…
Dannosità e controllo di Rhagoletis cerasi (L.) in ceraseti biologici della Sicilia occidentale.

Damage and control of Rhagoletis cerasi (L.) in organic cherry orchards in Western Sicily The study was carried out in 2009, 2010 and 2011 in organic cherry orchards in Western Sicily, were the control of Rhagoletis cerasi (L.), the cherry fly, is a problem for medium-late ripening cultivars. Presence and infestation of the dipteran were monitored on local cultivars and the effectiveness of pyrethrum, allowed in organic farming, was tested, comparing it with net bags. The presence of the cherry fly was recorded in all cherry orchards except in one isolated and recently planted. The infestation on fruits was not very high; it was absent until the end of May. Nets drastically reduced the infe…
The use of kaolin to control Ceratitis capitata in organic citrus groves
2011
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera Tephritidae), is the key pest in some organically managed citrus orchards in Sicily. The effectiveness of processed kaolin (Surround WP) for control of C. capitata damage was tested in field trials carried out in 2003-2004 on two early ripening citrus species: satsuma (Citrus unshiu Markow.) and clementine (Citrus clementina Hort. ex Tan.). Although the number of males captured in trimedlure baited traps was high in both years and in both orchards, the percentage of damaged fruit varied greatly from almost 0% (satsuma 2003) to more than 60% (clementine, both years). Nevertheless, the application of processed kaolin signifi…

Economic and Financial Comparison between Organic and Conventional Farming in Sicilian Lemon Orchards
2015
Sicily has a long tradition in citrus fruit cultivations that with vineyard and olive tree represent the main Mediterranean tree crops. In this paper we have evaluated the economic and financial sustainability of lemon production, both in organic farming and in conventional farming
Grano duro biologico: i consigli varietali.
2019
Nell’annata agraria 2018-19, per il 17° anno consecutivo, sono state effettuate prove collegiali di confronto tra varietà di frumento duro in coltura biologica, in collaborazione con diverse Istituzioni. Le prove sono state realizzate in 7 località, dislocate in 6 regioni del Centro-Sud (Sicilia, Sardegna, Puglia, Toscana e Marche), utilizzando uno schema sperimentale a blocchi randomizzati con 3 o 4 ripetizioni. In tutti i campi sono state messe a confronto le stesse 19 varietà, fornite non conciate dalle ditte sementiere.A livello produttivo le varietà Emilio Lepido, Iride e Antalis hanno fornito i migliori risultati, mentre le varietà Aureo e Furio Camillo sono risultate, rispettivamente…
Rhagoletis cerasi (L.) in Western Sicily: presence, damages and control in cherry orchards.
2012
The research was carried out from 2006 to 2010 in 12 cherry orchards in Western Sicily, were Rhagoletis cerasi (L.), the cherry fly, represents a problem for medium late ripening cultivars. Presence and infestation of the dipteran were monitored on local cultivars and effectiveness of some products allowed in organic farming was tested compared with net bags. The presence of the cherry fly was recorded in all cherry orchards except in two recently planted and isolated. The infestation on fruits was not very high until the end of May. Pyrethrum and spinosad did not lower the infestation, on the contrary nets reduced it.
