Contribution to the study of the egg parasitic Hymenoptera of the Azores Islands.

3rd International Symposium "Trichogramma and other egg parasitoids", San Antonio (Texas, USA), September 23-27, 1990.During the summer of 1989, several Hymenoptera egg and non egg parasitoids were captured in the island of Sao Miguel, Azores. The non egg parasitoids belong to the Ichneumonoidea, Cynipoidea, Ceraphronoidea, Proctotrupoidea (Diapriidae and Plastygasteridae) and Chalcidoidea (Aphelinidae and Eulophidae). The egg parasites are Proctotrupoidea (Scelionidae) and Chalcidoidea (Mymaridae and Trichogrammatidae). These last ones belong to the genera: Gryon, Telenomus, Ooctonus, Anaphes and Trichogramma. They are the first egg parasitoids to be recorded from the Azores. The Trichogramma is T. cordubensis, only known from Spain and North Africa

O contributo do projecto INTERFRUTA II para o desenvolvimento da fruticultura na ilha Terceira, Açores

13º Congresso da APDR (Associação Portuguesa para o Desenvolvimento Rural). Angra do Heroísmo, Julho de 2007.O Projecto Interfruta II é um projecto apoiado pelo programa Interreg III-B, desenvolvido nas Ilhas da Madeira, Tenerife (Canárias) e Terceira (Açores) destinado a contribuir para a promoção da fruticultura e viticultura nestas três regiões insulares, procurando uma melhoria dos conhecimentos sobre os problemas fitossanitários que afectam as macieiras, bananeiras, castanheiros e a vinha, aplicando técnicas que contribuam decisivamente para o conhecimento e procura de soluções, numa vertente de prospecção das pragas-chave, fauna auxiliar, doenças e vírus que afectam essas culturas. Destaca-se o facto de inicialmente se ter procedido à realização de 160 inquéritos aos produtores e ao levantamento e identificação, através de SIG, das áreas de produção frutícola da Ilha. Para a análise dos factores climáticos ao nível da parcela, foram instaladas nas três zonas em estudo, estações meteorológicas de leitura automática.ABSTRACT: The INTERFRUTA project is financed by the European Commission Interreg III-B Programme and was developed for the islands of Madeira, Tenerife and Terceira for the improvement of fruit and vineyard production in these three Atlantic regions. The project goal is a better knowledge of the phytossanitary problems that affect apples, bananas, chestnut and vineyards, applying methods that will contribute to solutions based on the survey of key pests, diseases and beneficial organisms. All these work began with a survey to 160 producers and those data permitted, applying GIS techniques to them to identify the Terceira island fruit and vineyard production areas. To register the climate conditions in each area studied fully automatic meteorological stations were put in each of the three studied areas

Populations and host/non-host plants of Spittlebugs Nymphs in olive orchards from Northeastern Portugal

The Aphrophoridae family contains important vectors of Xylella fastidiosa, a serious bacterial plant disease. In olive orchards, nymphs usually feed on the ground-cover vegetation. However, detailed information about their populations and host/non-host plants in some regions threatened by Xylella, such as the northeast of Portugal, is very limited. The goal of our work was to identify the vector species, nymphal development period, and their host and non-host herbaceous plants in olive orchards from northeastern Portugal. Ground-cover plant species hosting or not hosting nymphs were identified during the spring of 2017 to 2019 in olive orchards. Nymphal development period, nymph aggregation, and nymph's preferred feeding height of the ground-cover plants were recorded. The most abundant Aphrophoridae species was Philaenus spumarius followed by Neophilaenus sp. Nymphs developed from April to early May and showed a low number of individuals per foam (generally between one and three). They preferred the middle part of the plants. Philaenus spumarius feeds preferentially on Asteraceae and Fabaceae, and Neophilaenus sp. on Poaceae. Some abundant plants, such as Bromus diandrus, Astragalus pelecinus, Chrysanthemum segetum, Trifolium spp., Caryophyllaceae, and Brassicaceae, were barely colonized by Aphrophoridae nymphs. This knowledge is essential for the selection of the species composition of ground-cover vegetation to minimize the presence of vectors of X. fastidiosa in olive groves.This work was funded by European Union Horizon 2020 research and innovation program under grant agreement no. 727987 XF-ACTORS (Xylella fastidiosa Active Containment Through a multidisciplinary-Oriented Research Strategy), and Foundation for Science and Technology (FCT, Portugal) the financial support by national funds FCT/MCTES to CIMO UIDB/00690/2020.info:eu-repo/semantics/publishedVersio

CHALCIDOIDEA SPECIES (INSECTA: HYMENOPTERA) ON THE WOODY VINE CAMPSIS RADICANS (L.) SEEM. EX BUREAU

The woody vine Campsis radicans has extrafloral nectaries on the sepal, pedicel and green fruits. Its nectar attracts abundant Hymenoptera and especially representatives of the Chalcidoidea superfamily. During a six-year study (2012-2017) in the period from July to mid-October, 2117, specimens of Chalcidoidea from 13 families were collected. A total of 116 species were determined, of which 63 were new species to the Serbian fauna, and 11 to the fauna of the Balkan Peninsula. Campsis radicans can be considered as a “bait plant” that attracts many groups of Hymenoptera, which is very important for the study of their fauna, and in particular, for almost all the families of the Chalcidoidea superfamily. Campsis radicans is also significant since its extrafloral nectar is food to many Chalcidoidea species in periods when no other food is available. Given that almost all of the identified Chalcidoidea species are natural enemies of other insects (most commonly of phytophagous insects), C. radicans indirectly provides a natural balance in different terrestrial ecosystems
