“…The effects of seasonality on entomofauna, principally rainfall and humidity as the main predictors of abundance has already been observed in Isoptera , Diptera (Alves et al, 2014), Coleoptera (Santos et al, 2014a), Hymenoptera (Santos et al 2014b), Lepidoptera (Gusmão & Creão-Duarte, 2004) and other orders (Vasconcellos et al, 2010). However, for membracids this pattern has not been directly observed since they heavily rely on the cycle of their host plants (Wood, 1993;Creão-Duarte et al, 2012).…”

“…(Creão-Duarte et al, 2012), but also probably due to the reproductive cycle of the membracids (Wallace & Maloney, 2010). On the other hand, T. pallescens was the species less subjected because it is found exclusively on Caesalpinia pyramidalis Tul., arboreal plant that can remain green during periods of less rigorous droughts (Creão-Duarte et al, 2012). Similarly, E. euniceae was well represented in both seasons due to the perenniality of its main host plants Mimosa tenuiflora (Wild.)…”

“…During the dry season plants from intermediate and degraded areas suffer climate effects earlier, since the vegetation structure is composed mostly of herbaceous plants that soon lose their leaves and cease to house their guests, membracids. Where as in the preserved areas plants are larger and take longer to relay the effects of the drought, and thus can accommodate membracids for a longer period of time (Lima & Rodal, 2010;Creão-Duarte et al, 2012). Brown (1997) includes the Membracidae in the group of insects that are potential indicators for conservation and monitoring, in order to promote sustainable use of tropical forests due to the strong association of membracids with their host plants (Wood, 1993).…”

“…From these parts, they suck plant sap and release honeydew, which attracts ants, with which they establish biological associations (Moreira & Del-Claro, 2005;Fagundes et al, 2013). They have varying degrees of host selectivity (Creão-Duarte et al, 2012), and some species have gregarious habits, and may form colonies with a significant number of nymphs and adults (Wood, 1993). However, in general, in most degraded environments there are changes in abundance status, marked by strong dominance of a few species (Lopes, 1995;Creão-Duarte et al, 2012).…”

Temporal Variation of Membracidae (Hemiptera: Auchenorrhyncha) Composition in Areas of Caatinga with Different Vegetation Structures

et al. 2016

View full text Add to dashboard Cite

The diversity of membracids in different Caatinga vegetation structures (preserved, intermediate and degraded) was studied during dry and rainy seasons in 2006. We recorded 1,107 individuals, belonging to 13 species, mostly during the rainy season (693). Melusinella nervosa (Fairmaire, 1846), Enchenopa brasiliensis Strümpel, 2007 and E. eunicea Creão-Duarte & Rothéa, 2007 were the most abundant species, although this pattern varied in the three areas. M. nervosa and E. brasiliensis were the most abundant during the rainy and dry seasons, respectively, due to the resistance of its main host plant to seasonality and climate rigors. Thrasymedes pallescens (Stål, 1869) was the species least affected by seasonality, with 51.3% and 48.7% of the specimens collected in the rainy and dry seasons, respectively, followed by E. eunicea, with 65.6% and 34.4%. A cluster analysis showed that membracids from preserved areas in the dry season were more related to the ones from rainy season, highlighting the importance of these areas in the Caatinga for maintenance of these insects, which are strongly associated with their host plants.

Blowflies (Diptera, Calliphoridae) Associated with Pig Carcasses in a Caatinga Area, Northeastern Brazil

et al. 2014

Studies that focused on Calliphoridae associated with pig carcasses are abundant in southern and southeastern Brazil; however, there are few in northeast. Here, we present an inventory of the blowfly species associated with the stages of decomposition of pig carcasses in a caatinga area during dry and rainy seasons. The study took place at the Private Reserve for the Environmental Inheritance "Fazenda Almas," state of Paraíba, Brazil. Using a modified version of the Shannon trap, 32,909 adult specimens belonging to eight species were captured. During the dry season, Cochliomyia macellaria (Fabricius) (52.2%) and Chrysomya albiceps (Wiedemann) (39.9%) were the most abundant species. In the rainy season, when the majority of individuals were captured (93.7%), Chloroprocta idioidea (Robineau-Desvoidy) (71.1%) was the most abundant. Five decomposition stages were recognized, being the active decay the most attractive to colonization by blowflies, except for Lucilia eximia (Wiedemann), which was more abundant in the bloated stage.

Attractiveness of Different Food Resources to Dung Beetles (Coleoptera: Scarabaeidae) of a Dry Tropical Area

et al. 2017

Excrement scarcity is one of the main historical factors leading dung beetles to adapt to other food resources. In the Caatinga, a seasonally tropical dry forest, harsh environmental conditions seem to restrict the availability of food resources. In this scenario, the aim of our study was to experimentally investigate the attractiveness of different potential food resources to these insects in the Caatinga. Field samplings were performed, and we tested five resources in pitfall baited traps: excrement, carrion, fruits of two species of columnar cacti, and seeds of one species of Euphorbiaceae (Jatropha mollissima (Pohl)). In a controlled setting, we tested dietary preferences of Deltochilum verruciferum Felsche by offering one or two resources simultaneously. In the field experiments, 297 dung beetles (9 species) were recovered from the traps, and D. verruciferum was the most abundant species. Carrion and excrement were the most attractive resources. Controlled dietary preference tests with D. verruciferum evidenced that these beetles used all tested food resources, excrement and carrion most pronouncedly. Our findings support copro-necrophagy as the main feeding habit of D. verruciferum, but also suggest that alternative resources might be utilized if preferred resources are scarce.
