Resumo(s)
The chestnut moth is one of the principal pests on Terceira Island affecting
the quality of all chestnut production. Investigation work developed by the
Interfruta II Project (a project of interregional cooperation among the three
Atlantic regions: Azores, Madeira and Canaries) aims at increasing interest in fruit
and the vineyard production in the three partner regions. The chestnut moth (Cydia
splendana Hubner) (Lepidoptera: Tortricidae) is the only specie responsible for
chestnut fruit damage.
The monitoring of this pest using Delta traps with sex pheromone revealed
the adult abundance during the season. The higher activity period was between July
and October, the months when the chestnut harvest begins.
A map of Terceira Island using a GPS and ArcGis 8.0 software was made
showing the locality of all the chestnut production areas studied.
In the evaluated orchards, fruit damage reached its maximum of 38% at
Terra Chã, 218 m of altitude and a southern exposure, and a minimum of 0%
damage at Biscoitos, at about the same altitude but with a northern exposure. In
both cases, the percentages of infestation were achieved by analyzing a sample of
2.500 chestnuts for each parcel of land.
