Populational fluctuation of frugivorous flies (Diptera: Tephritoidea) in two orange groves in the State of Mato Grosso do Sul, Brazil

Abstract

PALAVRAS-CHAVE: Mosca-das-frutas, armadilha McPhail, Anastrepha, Ceratitis capitata, NeosilbaABSTRACT -This paper evaluated the capture of frugivorous flies (Tephritidae and Lonchaeidae) with plastic McPhail traps, in two commercial citrus groves, located in the municipalities of Anastácio and Terenos, in the state of Mato Grosso do Sul, Brazil. The aim of this work was to determine the populational fluctuation of adult frugivorous flies, and to study its relationship with the damaged fruits in the groves. The traps were placed about 30 m apart over the entire area in both groves, hung up approximately 1.70 m high from soil, in the canopy of the citrus plants. Eight traps were installed (two traps/ha) at Anastácio and 21 traps in Terenos (one trap/ha). The traps were baited with the hydrolyzed corn protein (5%) Tephritid TM (food bait). Evaluations were carried out from March 22, 1994 to March 23, 1996. Ceratitis capitata (Wiedemann) and 25 species of Anastrepha were caught during several months in both orange groves, but no fruit fly species were found infesting oranges. Neosilba sp. was caught from the traps during all the experiment and was also reared from the damaged oranges, thus suggesting that that fly can be a pest. The predominant species of frugivorous flies caught in the traps were: Neosilba sp., C. capitata, Anastrepha punctata Hendel and A. sororcula Zucchi. There was no correlation between adult frugivorous flies caught in the traps and the number of larvae and adult flies reared from the infested oranges collected in the groves.

Biodiversidade de moscas-das-frutas (Diptera, Tephritoidea) em matas nativas e pomares domésticos de dois municípios do Estado do Tocantins, Brasil

“…Canal et al (1998) A porcentagem relativa dos indivíduos de A. obliqua capturados no Estado do Tocantins é superior aos resultados para a mesma espécie, nos municípios de Anastácio e Terenos, Mato Grosso do Sul (Uchôa-Fernandes et al 2003). Naquele trabalho, em dois anos de amostragens, A. obliqua representou apenas 11% do total de indivíduos de moscas-das-frutas capturadas.…”

Hidrogenionic potential (pH) of the attractant, trap density and control threshold for Ceratitis capitata (DIPTERA: TEPHRITIDAE) on Hamlin oranges in São Paulo central region, Brazil

“…However, the best trap density for monitoring these insects in citrus is unknown and may depend on the fruit fly population. Although there are some indications on control thresholds for fruit flies , little research has been done on the relationship between insect trap captures and the damage caused (AGUNLOYE, 1987;UCHÔA-FERNANDES et al, 2003;GROUT et al, 2011). The objectives of this research were to evaluate the effect of pH of the attractant suspension and also estimate the control threshold for C. capitata at four trap densities, based on captures and fruit damage in Hamlin variety (sweet orange).…”

Biodiversity of Fruit Flies (Diptera: Tephritidae) in a Permanent Preservation Area Located at Araraquara - Sp

“…Dentro deste contexto, as informações referentes à análise faunística e também quanto a flutuação populacional de espécies de moscas-das-frutas permitem o entendimento sobre a ocorrência dos adultos destes tefritídeos, além da estimativa do número de gerações anuais e também a orientação das principais espécies para referida região, sendo que geralmente uma ou duas espécies ocorrem como predominantes (UCHÔA-FERNANDES et al, 2003;BOMFIM et al, 2007). Diante da escassez de pesquisas conduzidas em ambientes naturais, os objetivos da pesquisa foram identificar as espécies de moscas-das-frutas, bem como caracterizar estas populações por meio de análise faunística e observar a flutuação populacional destes tefritídeos em área de preservação permanente localizada no município de Araraquara -SP.…”
