Neosilba perezi (Romero & Ruppel) is known as the cassava shoot fly or shoot fly, because, unlike other species of its genus, its larvae feed exclusively on shoots of cassava (Manihot esculenta Crantz). These larvae kill the affected cassava shoots. Natural parasitism by a braconid, Phaenocarpa neosilba Arouca & Penteado-Dias, 2006, on shoot fly larvae was studied at 3 locations in the southwestern region of the state of São Paulo, Brazil. Larvae-infested shoots of cassava were collected at 3 distinct locations where cassava crops were grown. The shoots were kept in plastic boxes for pupation and emergence of adult flies and the parasitoid. The percentage of parasitism was separately correlated with temperature, rainfall, and age of the cassava plants. The average percent parasitism was 24.36%. A negative correlation between temperature and percent parasitism was observed at 1 location. At all 3 study areas percent parasitism of N. perezi showed a negative correlation with plant age. Therefore, given the high percent parasitism observed at the 3 locations, natural biological control may be an important factor in the population dynamics of N. perezi.

The objectives of this work were to assess the infestation of ten genotypes of cassava by the shoot fly Neosilba perezi (Romero & Ruppell) and to investigate effects of plant age, temperature or precipitation on cassava plants infestation by the shoot fly. Thirty-two individuals of each cassava genotype were planted and analyzed every two weeks in order to calculate the percentage of plants infested by shoot fly larvae at each sampling event and per genotype. Infestation by the fly was different across the genotypes. Genotype IAC Caapora 105-66 and genotype IAC Cascuda were resistant to shoot fly infestation, whereas the genotype IAC 15 was the most susceptible to this insect. Plant age may have an influence on infestation by shoot flies. Advanced plant age apparently favors lower or even inexistent infestation rates. However, infestation rate does not seem to be affected by temperature or precipitation.

L Romero & R F Ruppell) is one of the most prevalent. It attacks mainly the terminal shoots and causes infected plants to produce lateral shoots. Reports on this species are rare or inexistent; thus, the purpose of this study was to assess three different areas for N. perezi infestation. The survey commenced in March 2008 and ended in February 2009. Fortnightly analyses were performed starting 45 days after planting, calculating the rate of parasitism by N. perezi larvae in each study area. The areas were correlated separately for each parameter: fortnightly mean temperature, fortnightly mean rainfall, and plant age. The N. perezi larvae occurrence rate was higher in area 1 – which presented the highest population peaks in autumn and winter. There was only a single population peak in area 2, in winter; and area 3 presented the weakest population peak among the three, in November. The shoot fly population dynamics in the studied region is separately correlated to temperature, rainfall and plant age: temperatures above 23ºC, relatively high rainfall and older plants seem to have a negative effect on populations of this insect. Finally, a new species of parasitoid of N. perezi was found in the sampled areas. 1 aGisloti, L.J.1 aPrado, A., P. do uhttps://lonchaeidae.myspecies.info/cassava-shoot-parasitism-larvae-neosilba-perezi-romero-ruppell-diptera-lonchaeidae-southeastern-s-o00988nas a2200133 4500008004100000245011300041210006900154260003900223300001400262520049300276100001800769700002100787856004600808 2006 eng d00aNeosilba (Tephritoidea: Lonchaeidae) Species Reared from Coffee in Brazil, with Description of a New Species0 aNeosilba Tephritoidea Lonchaeidae Species Reared from Coffee in  aSalvador, BRAZILc10-15 September  a187 - 1933 a

Neosilba bella is introduced as a new species. Neosilba species are believed to be secondary invaders of fruit, so, little attention has been paid to its presence in coffee fruits. In this article we present a key to Neosilba species present in coffee fruits and describe a new species that is considered a primary invader. We hope this will help researchers working with coffee fruits to better quantify the economic importance of Neosilba species associated with coffee fruits.
