“…thus, by lowering the adult population, the quantity of larvae in the interior of the fruit can be reduced as well. Härter et al (2010), assessing peach orchards in the region of Pelotas (RS), verified that the populations of fruit flies were significantly lower in orchards which had toxic bait applied hidrolased protein + malathion) than in orchards which received insecticides in total area. despite the effect of the toxic bait, variations in the populations of fruit flies may occur due to factors such as microclimate and the ambient structure in the same region.…”

ABSTRACT-Diachasmimorpha longicaudata (ashmead) (hymenoptera: Braconidae) was introduced in 1994, in Northeastern Brazil, to evaluate its use in biological control programs of fruit flies. However, the effects of this specie on parasitism rates on the population of native parasitoids and fruit flies in Southern Brazil conditions are unknown. The objective of this study was to evaluate the impact of releases of D. longicaudata on the parasitism rates on loquats, peach trees, strawberry guava trees, and persimmons in an experimental area in the city of Eldorado do Sul, Rio Grande do Sul, in southern Brazil. In the first year of the study, fruits were collected and stored in the laboratory to obtain pupae. The flies or parasitoids that emerged were counted and identified. In the second year, adults of D. longicaudata were reared in the laboratory on Anastrepha fraterculus (Wied.) and larvae were released in the field (1.700 insects/ha) at each harvest time and the parasitism was evaluated in the same manner as in the first year. In the third year, the procedure was the same as the first year, without any releases. A significant increase in the rates of parasitism was recorded in the second year except in the persimmon, in which no parasitoid was recovered in any year. In the second year the number of emerged fruit flies was also lower. In the third year, no D. longicaudata were recorded and parasitism rates of parasitism were statistically similar to those found in the first year. The native parasitoids collected were Aganaspis pelleranoi (Brèthes), Doryctobracon areolatus (szépligeti), Doryctobracon brasiliensis (szépligeti) and Utetes anastrephae (Viereck). These species were found in at least one kind of fruit even in the years after the introduction of the exotic parasitoid, indicating that it was not harmful to these species. We conclude that D. longicaudata can help to reduce the population of fruit flies in Eldorado do Sul region, in Rio Grande do Sul.Index terms -biological control, Anastrepha fraterculus, Aganaspis pelleranoi, Doryctobracon, Utetes anastrephae.

“…Considering that the main form to control tephritidae in the orchards is through the application of insecticides (Härter et al, 2010), this low natural parasitism may be related to the frequent use of agrochemicals adopted as a management practice by the farmers. Araújo et al (2015) also found a small number of parasitoids, possibly due to the drought that occurred during the study period and also insecticides that were applied in conventional orchards.…”

The diversity of fruit flies (Diptera: Tephritidae) in commercial guava orchards in the Northwest region of Espírito Santo, Brazil was recorded. Also, their population dynamics, correlation with climatic factors and their parasitoids were recorded. This study was carried out in three commercial guava orchards of the cultivar Paluma, located in the municipality of São Roque do Canaã, Central region of the Northwestern Capixaba territory, from October 2013 to September 2014. The population monitoring of fruit flies was done by installing McPhail traps provided with an attractive solution (BioAnastrepha®), hung ¾ of the guava canopy height, starting from the ground level. After obtaining the data, the following indexes were calculated: pupal viability (PV), parasitism (P) and fruits infestation (I). A correlation analysis was performed between the number of flies collected, and the meteorological variables of the region. A total of 31.51 kg of guava was collected, in which 18.31 kg were collected in the guava trees and 13.2 kg were found on the ground. 1,699 pupae were obtained, and from these, 442 flies emerged with three genera, Anastrepha species and one genus, Ceratitis (Ceratitis capitata Wiedemann). Only two parasitoids were obtained from the fruits from the ground, which both belong to Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae). The correlation analysis showed a strong correlation between the flies and fluctuating temperatures. Population peak of fruit flies occurred in February 2014.

O objetivo deste trabalho foi avaliar a eficiência da técnica de confusão sexual, com o feromônio sexual sintético composto (Z)-11-hexadecenal (Z11-16: Ald) a 1,8% e (Z)-13-octadecenal (Z13-18: Ald) a 1,8%, no controle da população de traça-dos-cachos, Cryptoblabes gnidiella (Lepidoptera: Pyralidae), em cultivares de videiras (Vitis vinifera) destinadas à produção de vinhos. Os experimentos foram realizados em duas localidades na região do Vale do São Francisco, em áreas comerciais de produção de uva para processamento, com as cultivares Cabernet Sauvignon, Petit Verdot, Tempranillo e Chenin Blanc. Os tratamentos avaliados foram os seguintes: confusão sexual com uso de liberadores Splat ("specialized pheromone and lure application technology"), aplicados com pistola manual a 500 pontos por hectare (2 g por ponto); e testemunha sem aplicação. O efeito da técnica sobre os adultos de C. gnidiella foi avaliado com uso de armadilha tipo Delta, iscada em um septo com 2 g de feromônio sintético da mesma formulação. Os danos nos cachos foram avaliados à colheita. O uso da técnica de confusão sexual reduziu a captura de adultos de C. gnidiella em mais de 59% na 'Tempranillo', 68% na 'Chenin Blanc', 80% na 'Cabernet Sauvignon' e 97% na 'Petit Verdot'. À época da colheita, os danos nos frutos foram reduzidos de 65 a 100% nas áreas tratadas. O feromônio sexual sintético é eficaz para reduzir o acasalamento de C. gnidiella em vinhedos, com o uso da técnica de confusão sexual.
