ABSTRACT: The eucalyptus snout beetle Gonipterus scutellatus, was first reported in Galicia in 1991. In 1994 releases of the Gonipterus scutellatus egg parasitoid Anaphens nitens were initiated in some specific points to control the pest. However, it was not until 2000 that massive releases of the pest were performed, so the pest has not been controlled yet. Thus, there is a need to perform a biological control together with other control techniques not harmful for Anaphens nitens. The effectiveness of several insecticides has been studied in laboratory assays in order to determine their effect on both the snout beetle and Anaphens nitens. Of those insecticides assesed (azadiractin -1%, 3%, 3,2%-, Bacillus thuringiensis, Beauveria bassiana, deltametrin, etofenprox and flufenoxuron), piretrinoids have proved to be more effective on pest control, but causing Anaphens nitens death. Flufenoxuron, azadiractin 3,2 % performed the control of the snout beetle larvae causing no damage to Anaphens nitens. These insecticides proved to be the best option to perform an integrated pest management. KEYWORDS: Anaphes nitens, integrated control, eucalyptus, Gonipterus scutellatus, insecticides. |

ABSTRACT: Effect of
cyproconazole on Armillaria mellea control in grapevine. Armillaria
mellea causes white root rot in a wide range of hosts, including grapevine.
In Galicia this disease inflicts significant economic losses, due to the
insufficiency of preventive measures and the lack of an effective method of
control. An experiment was carried out to evaluate in vitroeffects of
eleven active ingredients on mycelial growth of A. mellea. Best results were
obtained for cyproconazole, which showed a clear fungicide activity and was
selected to be tested under field conditions. A field experiment was designed
to study vineyard: healthy, with initial infection and severely affected
grapevines. Despite of this after two years, the dose of 100mg/L controlled the
disease in most infected plants, further research is needed to confirm the
efficacy of cyproconazole for the contro lof A. mellea in
grapevine KEYWORDS: Armillaria mellea , Grapevine, Cyproconazole, chemical control, white root rot. |

ABSTRACT: Fruit yield and
characteristics of three cultivars of mirabelle plum (Prunus insititia
var. syriaca) were evaluated from 1990-1997 in northwest Spain. "Rosal" is the
local non-improved cultivar, highly susceptible to leaf fungal diseases; 'Nancy
1510' and 'Nancy 1725' are improved virus-free clones developed by the Institut
National de Recherche Agromique (INRA, Bordeaux, France) which had not
previously been cultivated in Spain. 'Nancy 1510' gave the best yield (avarage
annual production 31 kg per plant, versus 27 kg for'Nancy 1725' and 6 kg for
'Rosal'), which increased steadily with age. 'Nancy' fruits were on average
larger (average weight about 9 g, versus 7.7 g for 'Rosal' fruits). These
diferences may be of genetic origin, althought they could also be attributed to
the impact of Seterum purpureumon 'Rosal' plants. Althought affected by
this fungal phatogen, 'Nancy 1510' and 'Nancy 1725' adapted well to the climate
of the study area. KEYWORDS: Plum syriaca ,Calacarus carinatus, Prunus insititia, mirabelle, Production northwest, Spain. |

ABSTRACT: The occurrence and distribution of eryophyid mites in the south of Galicia and north of Portugal is reported in this work. A survey was performed on ten Camellia specimens, where 15 to 20 leaves and flower buds with symptoms of mite's attack were collected from March to May 2002. The result of this survey showed that Calacarus carinatus was the eriophyid mite more frequently found infesting camellias, since it was present in Camellias planted in all surveyed points; Acaphylla steindeweni, recently detected in Galicia was also found, and Cosetacus camelliae which appeared in lower densities. KEYWORDS: Acaphylla steinwedeni Calacarus carinatus, Cosetacus camelliae, eryophyid, Galicia, Portugal. |
