“…According to Namaghi & Husseini (2009) and Marcos-García et al . (2012), the collecting method can influence the diversity and richness of species obtained, and this might explain the large difference between our results and the results of Morales & Köhler (2006, 2008). The latter authors used a manual collecting method, and the 2006 study was specifically directed at obtaining flies from Eryngium horridum Malme (Apiaceae).…”

The natural areas of the Coastal Plain of Rio Grande do Sul (CPRS) have suffered fragmentation due to anthropic action. The faunal surveys offer a low-cost method to quickly evaluate environmental alterations, and Syrphidae flies are often used as models in this kind of study. We aimed to ascertain the diversity of Syrphidae in the South region of Brazil by estimating its species' richness, and to use this data to identify new areas for conservation. In this survey Malaise traps were installed for 8 days in the CPRS, which was divided into five regions. Each region was subdivided into seven collecting areas and each of those areas received four traps, totaling 140 traps. A total of 456 Syrphidae individuals from 18 genera and 49 species were collected. In Region 1, there were nine exclusive species; in Region 2, there were three; in Region 3, there were 13, ten of which came from Estação Ecológica do Taim (ESEC Taim). In the Individual-based rarefaction analysis, Region 1 possessed the largest number of expected species out of the regions in the CPRS; we found 97% of these species. This insect collection effort, as one of the first in the CPRS, has broadened the known geographic distributions of 11 species of Syrphidae, and also indicated areas to be conserved. Additionally, it gave support for expanding ESEC Taim and creating new areas of conservation in Region 1, in Arroio Pelotas and Arroio Corrientes.

“…The morphology of flowers of the Apiaceae is compatible with the short mouthparts of adult Syrphidae hoverflies, thus facilitating access to nectar and pollen (Morales and Köhler, 2008). Flowers of the Asteraceae, including marigold species, are also attractive to syrphids, as verified by Robertson (1929), who reported that 25% of the 257 species of this family serve as hosts for hoverflies, and by Sajjad and Saeed (2010) who established that the Asteraceae is one of the families most visited by Syrphidae.…”

The effects of intercropping of Brassicaceae with coriander (Coriandrum sativum), dill (Anethum graveolens), African marigold (Tagetes erecta) and calendula (Calendula officinalis) on the abundance, species richness and diversity of predators and parasitoids of Lipaphis erysimi have been assessed. The numbers of aphids, parasitized aphids and natural enemies were determined during two consecutive phases. The first period comprised the vegetative phase of companion plants up to the onset of flowering and the development of kale up to the start of harvesting, while the second period encompassed the late flowering of companion plants up to senescence and the complete harvesting phase of kale. The establishment of L. erysimi and its natural enemies during the first period was enhanced by the climatic conditions and the additional nutritional resources offered by companion plants. Over the complete 13 week period, the abundance of natural enemies in kale intercropped with African marigold, calendula, coriander and dill increased by factors of 3.1, 2.1, 2.0 and 1.6, respectively, compared with the kale monoculture, while species richness increased by 1.8-fold in kale/African marigold intercrop and by a factor of 2.7 in the other treatments. The predominant predators were Syrphidae larvae and Hippodamia convergens whereas the predominant parasitoid was Diaeretiella rapae. The diversity of natural enemies was similar in all crops owing to the high proportion of syrphids in relation to the other groups of insects. The improved resources offered by companion plants can be exploited in the conservative biological control of insect pests.

“…Syrphidae larvae are known as important natural enemies of aphids in different crops (Oliveira et al, 2003;Ghahari et al, 2008), including greenhouses (Pimentel, 2007), due to their capacity of consuming great amounts of insects during its developmental time (Marinoni et al, 2007). Furthermore, adults perform an important role as pollinators of different vegetable species (Morales and Köhler, 2008). Thus, further studies such as those related to T. duplicatus biology and also multiplication techniques are necessary to investigate the possibility of using this predator as a biological control agent for both M. ochroloma and M. semilaevis larvae in different Brassicaceae crops.…”

Microtheca spp. (Coleoptera: Chrysomelidae) are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS), southern Brazil, they are found on forage turnip, Raphanus sativus L. var. oleiferus Metzg., which is commonly grown during fall/winter seasons. This work reports the predation of Microtheca spp. larvae by Toxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae) larvae, on forage turnip crop, in Santa Maria, RS. This register provides new information about Microtheca spp. natural enemies in Brazil, which might be a new option for integrate pest management of these species.Keywords: Brassicaceae, Raphanus sativus L. var. oleiferus Metzg., Predator.
