“…Traps with attractive bait contained banana fermented for 48 hours in 100 g portions and the traps were exposed for 48 hours in order to capture frugivorous drosophilids (Martins et al 2008). This exposure time is in agreement with other studies for surveying drosophilids (Martins 1987; de Medeiros & Klaczko 2004; Penariol et al 2008; Coutinho‐Silva et al 2017; Mendes et al 2017, 2021; Duarte et al 2018), as well as effects of the loss of bait attractiveness after 48 hours (Nascimento et al 2014). After this period, the collected drosophilids were removed from the traps with a mechanical sucker and stored in 96% alcohol and individualized by traps.…”

To mitigate the impacts of deforestation, Brazilian legislation requires the implementation of a Degraded Area Recovery Plan (PRAD). One way to assess the recovery of these areas is using bioindicators. This research tested the use of the drosophilid community structure as an indicator to evaluate post‐mining area restoration. We compared two regeneration techniques within the same chronological sequence and as reference used the forest remnants within the exploration area. The study was conducted in the municipality of Paragominas—Pará, in areas managed by Hydro mining company. Five sites of forest remnants were selected, five in natural regeneration and five in the nucleation technique, the latter two making up the PRADs. A total of 5,919 male drosophilids were collected belonging to 10 genera, and 32 species. Rarefaction showed the curves of the PRADs to be more asymptotic, than forested areas. Forest areas are potentially richer and, on average, have lower abundances and lower diversity. Beta diversity components in the forest present greater turnover and less nestedness processes when compared to PRADs areas. The PRADs showed no differences between them for any of the analyzed patterns. D. nasuta and D. sturtevanti behaved as generalists in relation to habitats, D. paulistorum and D. willistoni as forest specialists. D. malerkotliana, D. simulans, Scaptodrosophila latifasciaeformis, and Zaprionus indianus behaved as specialists in PRADs areas. The structure of the drosophilid community varied according to the environment, proving to be a good indicator for forest and regenerating environments, but it did not detect differences between the PRADs environments in early regeneration (6 years).

RBE 57 1-6 Revista Brasileira de Entomologia xxx (2015) xxx-xxx w w w . r b e n t o m o l o g i a . c o m a b s t r a c tThe population dynamics of a species tends to change from the core to the periphery of its distribution. Therefore, one could expect peripheral populations to be subject to a higher level of stress than more central populations (the center-periphery hypothesis) and consequently should present a higher level of fluctuating asymmetry. To test these predictions we study asymmetry in wing shape of five populations of Drosophila antonietae collected throughout the distribution of the species using fluctuating asymmetry as a proxy for developmental instability. More specifically, we addressed the following questions: (1) what types of asymmetry occur in populations of D. antonietae? (2) Does the level of fluctuating asymmetry vary among populations? (3) Does peripheral populations have a higher fluctuating asymmetry level than central populations? We used 12 anatomical landmarks to quantify patterns of asymmetry in wing shape in five populations of D. antonietae within the framework of geometric morphometrics. Net asymmetry -a composite measure of directional asymmetry + fluctuating asymmetry -varied significantly among populations. However, once net asymmetry of each population is decomposed into directional asymmetry and fluctuating asymmetry, most of the variation in asymmetry was explained by directional asymmetry alone, suggesting that populations of D. antonietae have the same magnitude of fluctuating asymmetry throughout the geographical distribution of the species. We hypothesize that larval development in rotting cladodes might play an important role in explaining our results. In addition, our study underscores the importance of understanding the interplay between the biology of a species and its geographical patterns of asymmetry.

“…Adults of Z. indianus species were collected from three distinct locations in Brazil (Figure S1). The collections were conducted between April and June 2018, using ten closed traps baited with banana and natural yeast (Penariol et al., 2008) distributed at five collection points per area, with three traps per point. The traps were positioned at 1.80 m from the ground, spaced 3 m apart, and kept in place for three days until the collection, sorting, and individualization of females of Z. indianus in tubes containing banana‐agar culture medium for the establishment of isofemale lineages.…”

Geographical and sex‐specific effects of malathion insecticide selection in African fig fly Zaprionus indianus Gupta, 1970 (Diptera: Drosophilidae)

The African fig fly (AFF) Zaprionus indianus Gupta, 1970, is an invasive species that has caused significant damage to several monoculture crops since its introduction in the Brazilian territory, resulting losses for farmers and decrease of fruit productions. A way to manage fruit pests is the chemical control, which could act as a selective pressure against genetic variation in the insect populations. The esterases are detoxifying enzymes that can respond to the selection by insecticides, they are conserved in evolution, and are involved in the hydrolysis of esters, including insecticide degradation. Esterases can be identified by isoenzyme electrophoresis, which is a valuable tool for genetic, biochemical, and ecological studies, particularly in approaches with pest species. This experimental study aimed to evaluate survival and esterase polymorphisms at the Est2 and Est3 loci in three different geographical populations of Z. indianus from Brazil (Aracaju, Uberaba and Florianópolis) after exposition to organophosphate malathion. We identified patterns of sex‐specific genetic variation that indicate a response to insecticide exposition. These results indicated that the insecticide biological response in this species is sex‐dependent, providing relevant information about the AFF‐malathion interaction. This study may contribute to the development of more effective and sustainable management strategies for AFF control in Brazil using genetic and ecological approaches.
