Conteúdo: |
Com o objetivo de estudar a eficiencia do teste de estresse hidrico na avaliacao da qualidade fisiologica de sementes de tomate industrial (Lycopersicon esculentum Mill), cinco lotes da cultivar IPA-5 foram analisados pelos testes de germinacao, primeira contagem, de frio sem solo, envelhecimento acelerado, condutividade eletrica, emergencia em campo e comprimento das plantulas sob estresse hidrico nos potenciais de 0, -0,2, -0,4 e -0,6 MPa. Os trabalhos foram realizados no laboratorio de analise de sementes e no campo experimental do CPATSA, em Petrolina, PE. As determinacoes foram conduzidas com quatro repeticoes, em delineamento experimental inteiramente casualizado. Os resultados indicam que o teste de germinacao sob estresse hidrico de -0,4 MPa pode ser usado para estimar o desempenho das sementes de tomate em situcacoes desfavoraveis de disponibilidade hidrica no solo. |

The objective of this study was to evaluate the potential of the pioneer plant species Bellucia grossularioides (L.) Triana (Melastomataceae) to act as a reservoir for parasitoids of fruit flies in the Brazilian Amazon. We collected 48 samples of fruits (total of 4,012 fruits, 43.98 kg) during the months of July, August and September of 2013, in 15 of the 16 municipalities of Amapá State, Brazil. All samples showed infestation by fruit flies, with rates varying from 60.6 to 239.1 puparia/kg of fruit (mean of 106.8 puparia/kg of fruit). The percentage of emergence varied 18.6 to 64.3% (mean of 39.9%). Specimens of Anastrepha coronilli Carrejo & González (Diptera: Tephritidae) were obtained from all samples collected. Specimens of Neosilba (Diptera: Lonchaeidae) were obtained from five samples, where they were represented by Neosilba bella Strikis & Prado and Neosilba glaberrima (Wiedemann). The mean percentage of parasitism was 12.8%, varying 4.7 to 26.7%. Four species of parasitoids were obtained: Doryctobracon areolatus Szépligeti), Doryctobracon sp.2, Opius bellus Gahan (Braconidae) and Aganaspis pelleranoi (Brèthes) (Figitidae). Doryctobracon areolatus, present in all municipalities sampled, was the most abundant species. Considering that B. grossularioides is a plant species that is abundant in the area sampled, its relevance with respect to the maintenance of the population of parasitoids is discussed in the context of the integrated management of fruit flies in the Amazon.
