“…The average infestation rate/kg was higher than those reported by other studies such as the survey carried out by Santos et al (2012), in which they found infestation of 99.3 puparium/kg in collections carried out in organic guava crops in the municipality of Maceió, Alagoas. Similarly, Moura & Moura (2011) found infestation levels lower than the findings of the present study, reporting 30.3 puparium/kg in samples collected in a guava orchard in Fortaleza, Ceará.…”

Fruit flies are phytophagous insects that are important because of the damages caused to fruits, mainly by larvae that feed on the pulp. Surveys of the diversity of these tefritids are still scarce in Brazil, especially in the Amazon region, the objective of this study was to establish the tritrophic relationship existing between species of Anastrepha, their parasitoids, and the fruits acerola (Malpighia emarginata DC.), mango (Mangifera indica L.), and guava (Psidium guajava L.) in the municipality of Brasil Novo, Pará. Freshly fallen fruits were collected weekly from January to December 2018, in three farms. Throughout the survey, 4,324 puparium were collected in guavas, 2,682 in mangoes, and 644 in acerolas. The species Anastrepha obliqua (Macquart, 1835) were identified in mango (90.3%), acerola (7.7%) and guava (2.1%), and Anastrepha striata Schiner, 1868 were identified in guava (98.8%) and acerola (1.2%). Five species of parasitoids were identified in association with A. obliqua and six species of parasitoids were identified in association with A. striata. The specie Doryctobracon areolatus (Szépligeti, 1911) was the most frequent among the species of parasitoids recorded.

Parasitoides (Hymenoptera) De Moscas-Das-Frutas (Diptera: Tephritidae) No Semiárido Do Estado Do Ceará, Brasil

RESUMO -As moscas-das-frutas (Diptera: Tephritidae), Anastrepha spp. e Ceratitis capitata (Wiedemann), são importantes pragas da fruticultura no Brasil. Para desenvolver um sistema sustentável de manejo integrado para este grupo de pragas, é fundamental conhecer os parasitoides (Hymenoptera) que podem regular as populações destes tefritídeos. Portanto, o objetivo deste estudo foi relatar a diversidade, a distribuição geográfica e as relações tritróficas dos himenópteros parasitoides de moscas-das-frutas, na região do Baixo Jaguaribe, no semiárido do Estado do Ceará, Brasil. Foram realizadas coletas de frutos em sete municípios da região, no período de maio de 2010 a maio de 2013. Os frutos foram levados para o laboratório, onde foram contados, pesados, colocados em bandejas plásticas com vermiculita e fechadas com tecido voile. Após sete dias, a vermiculita foi peneirada para a obtenção dos pupários das moscas-das-frutas que, em seguida, foram contados e acondicionados em placas de Petri, onde permaneceram até a emergência dos adultos (moscas e/ou parasitoides). Quatro espécies de parasitoides foram encontradas: Doryctobracon areolatus (Szépligeti), Opius bellus Gahan, Utetes anastrephae (Viereck) (Braconidae) e Tetrastichus giffardianus Silvestri (Eulophidae), sendo o mais frequente e com maior distribuição geográfica na região, D. areolatus. Doryctobracon areolatus foi mais comum em associação com espécies de Anastrepha -A. sororcula Zucchi, A. obliqua (Mcquart) e A. zenildae Zucchi, em frutos nativos e com C. capitata em frutos exóticos. Tetrastichus giffardianus foi obtido apenas em associação com C. capitata, em frutos nativos e exóticos. Estas informações podem servir de base para inserção de parasitoides em futuros programas de manejo integrado de moscas-das-frutas, nas condições do Semiárido brasileiro.

PARASITOIDS (HYMENOPTERA) OF FRUIT FLIES (DIPTERA: TEPHRITIDAE) IN SEMIARID AMBIENT, IN THE STATE OF CEARÁ, BRASILABSTRACT -Fruit flies (Diptera: Tephritidae), Anastrepha spp. and Ceratitis capitata (Wiedemann), are important pests of Brazilian fruit-growing. In order to develop a system of pests integrated management in any region, it is essential to know the parasitoids (Hymenoptera) which can regulate the populations of these tefritids. Therefore the objectives of this study were to know the diversity, geographic distribution and tritrophic relations of the hymenoptera parasitoids of fruit flies, in Baixo Jaguaribe region, located in Ceará semiarid, Brazil. Thus, fruits were collected in seven counties of the region, from May 2010 to May 2013. The fruits were taken to the laboratory, where they were counted, weighted, put in plastic trays with vermiculite and closed with voile. After seven or ten days, the vermiculite was sieved to obtain the puparium of the fruit flies. The puparium were counted and put in Petri dish, where they stayed until the emergence of the adults (flies and/or parasitoids). Four species of parasitoids...

-The objective of this study was to evaluate the effects of different water depths and nitrogen fertilization levels applied by fertigation on the physical attributes of guava fruits cv. Paluma. The study was carried out taking into account factors water depths (1144, 1465, 1785 and 2106 mm) and nitrogen fertilization levels (50, 100, 150 and 200 kg ha -1 ). The water depths 1730 and 1750 mm increased production and the average weight of guava fruit in, respectively, 25.1 and 31.6%. The applications 178 and 152 kg N ha -1 increased at 67.1% in the production of fruits and 16.3% the average fruit weight. The combined application of 150 kg N ha -1 and 1789 mm of water amounted to 63.3% of the total weight of fruit. The equatorial diameter of the fruit was influenced by individual water depths applied evidencing an increase of up to 26.8%. Already combinations 200 kg N ha -1 and 1746 mm of water increased the longitudinal diameter of the fruits by 18.77%. The application of water depth to 1144 mm, associated with 143 kg N ha -1 gave index of the most satisfactory way to guava fruit. Keywords
