“…There are no behavioral data on how male (or female) T. dilatus use their mandibles besides capturing food. It is unlikely that they use them to interact with the paper wasps A. vicina, whose nest refuse piles they are occupying, because A. vicina is a well-studied organism (e.g., Zucchi et al, 1995;Sakagami et al, 1996;Baio et al, 1998;Mancini et al, 2006;Oliveira, Noll & Wenzel, 2010;Moretti et al, 2011;Souza et al, 2013) and there are no reported interactions.…”

The rove beetle Triacrus dilatus is found in the Atlantic forest of South America and lives in the refuse piles of the paper wasp Agelaia vicina. Adults of T. dilatus are among the largest rove beetles, frequently measuring over 3 cm, and exhibit remarkable variation in body size. To examine sexual dimorphism and allometric relationships we measured the length of the left mandible, ocular distance and elytra. We were interested in determining if there are quantifiable differences between sexes, if there are major and minor forms within each sex and if males exhibit mandibular allometry. For all variables, a t-test was run to determine if there were significant differences between the sexes. Linear regressions were run to examine if there were significant relationships between the different measurements. A heterogeneity of slopes test was used to determine if there were significant differences between males and females. Our results indicated that males had significantly larger mandibles and ocular distances than females, but the overall body length was not significantly different between the sexes. Unlike most insects, both sexes showed positive linear allometric relationships for mandible length and head size (as measured by the ocular distance). We found no evidence of major and minor forms in either sex.

“…These insects belong to the order Hymenoptera, family Vespidae, and they play various ecological roles, acting as predators of pest crops such as coffee (Coffea arabica L.) and Surinam cherry (Eugenia uniflora L.) (sOuza et al 2013), and they are frequent visitors of various angiosperms (cLemente et al 2012) and pollinators of some families (GranJa & BarrOs 1998).…”

Biodiversity of Social Wasps (Hymenoptera: Vespidae) at Altitudes Above 1600 Meters in the Parque Estadual da Serra do Papagaio, State of Minas Gerais, Brazil

Abstract. The Parque Estadual da Serra do Papagaio is the largest area of natural preservation in the south of Minas Gerais, with areas of Floresta Atlantica, Floresta de Araucaria and Campos de Altitude. Although this is an area of biological importance, there are many groups that have not yet been studied there: for example social wasps, which are insects belonging to order Hymenoptera, family Vespidae, which play an important ecological role in different ecosystems. This study was carried out in the aforementioned natural preservation area at altitudes between 1600 and 2200 m in 20 days of sampling between July of 2013 and April of 2014, using active searches and attractive traps to record species. Twenty two species of social wasps were sampled, distributed in seven genera. This number is small compared to counts from other studies in this state, which is probably due to the high altitude of this area. There was a predominance of nests with protective casings in the most common species recorded, and the most populous species was Polybia fastidiosuscula Saussure, a finding that can be explained by the superior thermoregulation afforded by the nest casing. Two other common species were Mischocyttarus drewseni Saussure, and Mischocyttarus rotundicolis (Cameron), which have nests without casings; however, these species have dark coloration, as does the substrate used for nesting, and can therefore enhance retention of solar radiation; nevertheless, other biotic and abiotic factors could be involved.

“…These groups include many of the major urban tree pests, and specifi c parasitoids may be available for many of them as control agents. General measures, such as promoting fl oral diversity as sources of nectar for generalist insect predators such as native social wasps (Souza et al 2013 ) can help to provide alternatives to pesticide use. Surveillance to detect early incidence of key pest taxa can help to reduce the more severe impacts likely if the pest is already well-established, and many ingenious approaches to such early detection and monitoring have been proposed.…”

The major interest of 'Urban entomology' developed largely from concerns over pest insects and ways to eradicate or suppress them in and near human dwellings and settlements. Pest problems are still a major entomological focus in urban areas, but their long domination of interests in urban insects, emphasised by Frankie and Koehler ( 1978 ), has lessened considerably, although insect pest management remains an almost universal priority theme in urban environments as the variety of insect impacts on human wellbeing continues to diversify. Many insect groups, including numerous innocuous forms, are fi rst noticed by people in urban environments, and the many insects that are associated in some way with anthropogenic regimes lead to increasing practical and psychological concerns, with efforts to suppress them as putative 'pests'. Other than those causing direct tangible damage or injury, many 'urban pest insects' are essentially defi ned as such by peoples' attitudes and reactions -urban people 'defi ne under what circumstances insects are a problem ' (Dreistadt et al. 1990 ), so that aesthetic factors such as appearance are added to (or replace) features such as economic injury or loss. Domestic pests , those found mainly in buildings, benefi t from a narrow and relatively stable range of climate conditions and from assured shelter and resources. Both domestic pests and the larger array of 'periurban pests' (Robinson 2005 ) persist largely through the presence of reservoir populations and habitats across the landscape, from where colonisation of homes and gardens can be easy and frequent. Their management includes attention to those habitat networks -examples such as pest mosquitos breeding in small water pools such as abandoned swimming pools and rain collected in discarded cans or tyres, wasp nests on old walls or in tree cavities, and cockroaches in water pipes are cited commonly, but almost any natural vegetation or anthropogenic feature can be exploited by insects. Many pest insect species are widespread and, whether native or (as commonly) alien, their impacts may transcend rural and urban environments. A number of generalist feeders, most 104 commonly herbivores, can affect commercial plantations or forests and amenity or garden plantings (including ornamentals, lawns, vegetables, street trees, and many other plant categories) alike, across a variety of scales and environments. Their impacts are thus scale-related: the smaller areas affected by widespread agricultural or forestry pests in urban areas may demand clearly focused management, and the range of treatment options available for use over large areas be restricted.Effects can be very varied. Adults of the polyphagous Japanese beetle ( Popillia japonica , Scarabaeidae ), for example, have been recorded feeding on more than 300 plant species over 79 families (Potter and Held 2002 ) since it was introduced to the eastern United States in 1916, in imported nursery stock. As one facet of a diverse suite of control measures for this now widespread pest, s...
