In this article I review the diet and feeding behaviour of adult scorpionflies in the nine extant families. Members of the Apteropanorpidae and Panorpidae are saprophagous on dead and decaying invertebrates, and the only known eomeropid Notiothauma reedi is also saprophagous on animal matter. Bittacids are predacious on a variety of invertebrates, predominantly insects. Both bittacids and panorpids supplement their diet with a variety of food sources such as nectar, and members of the Nannochoristidae most likely utilise nectar as the primary food source. Adult Panorpodidae are phytophagous, and all species of Boreidae are also regarded as phytophagous, although feeding on invertebrate carrion has also been reported for this family. The diets of the Meropeidae and Choristidae in natural habitats are unknown, although choristids may be saprophagous based on laboratory investigations. Nuptial feeding is a feature of the Bittacidae and Panorpidae, whereby the male provides the female with a food item as a prelude to or during courtship, and the female feeds on it during copulation. Relating head morphology to known diets indicates some patterns. The rostrum is more elongate in those taxa known to feed predominantly on animal matter, and shorter and wider in plant-feeding taxa such as the Panorpodidae. An exception is the predominantly phytophagous Boreidae, in which most species have a long rostrum.

We present data from the first study of successional patterns of insect fauna in Calabria (southern Italy). The aim was to identify and qualitatively assess the major taxa of forensic importance in this region. Studies were conducted in autumn-winter 2006, summer 2007 and winter 2008 in the Botanical Garden, University of Calabria. Over 50 taxa were collected and identified. The most abundant fly species were Lucilia caesar (Linnaeus, 1758), L. sericata (Meigen, 1826), Chrysomya albiceps (Wiedemann, 1819), Calliphora vicina Robineau-Desvoidy, 1830, C. vomitoria (Linnaeus, 1758), Sarcophaga spp., Amobia sp ., Musca domestica Linnaeus, 1758, and Muscina stabulans ((Fallen). The successional patterns, relative abundance of adult sarcosaprophagous insects, carcass decay, diversity and seasonality of species are described and the taxa useful for estimating the post-mortem interval (PMI) are identified. The data of this study could be very useful for further forensic investigations in southern Italy.

The cerrado savanna of Brazil embraces an area of approximately 2 million km 2 , in which vegetation physiognomies may vary from open grassland to forest with a discontinuous herbaceous layer. Here we describe the main ecological factors accounting for the prevalence of ants on cerrado foliage, and present a general characterization of the arboreal ant fauna of this savanna. The high incidence of ants on cerrado foliage results mostly from the wide occurrence of predictable liquid food sources in the form of extrafloral nectaries (EFNs) and insect honeydew, which act as efficient promoters of ant activity on vegetation. In addition, stem galleries and cavities constructed by boring beetles and insect galls create a nesting space frequently used by arboreal ants. Specific studies involving ants, herbivores and plants are reported to demonstrate the impact that foliage-dwelling ants can have on phytophagous insects, herbivory levels, and ultimately on host plants. These studies show that: (i) ants visit EFNs and likely benefit from this resource; (ii) EFN-gathering ants can benefit particular plant species by reducing herbivory and increasing plant fitness; (iii) presence of EFNs does not affect ant species richness within a given tree; (iv) there is not a particular ant species composition typical of plants with EFNs; (v) although plants with EFNs are visited by more ant individuals than non-nectariferous plants, this visitation pattern does not translate into lower numbers of herbivores on the nectariferous plant community. We suggest some promising research avenues to elucidate how community-level parameters can be tied to the ecology of ant-plant associations in cerrado.

Nitidulid beetles of the genus Carpophilus are significant pests of a wide variety of fruits and grains and are also vectors of harmful microorganisms. The beetles are difficult to control with conventional insecticides because the beetle damage typically occurs just before harvest, when toxic residues must be avoided. These insects are generally attracted to scents such as from overripe or decomposing fruit. Starting in the 1960's, research was done to develop fermenting fruit and similar materials as trap baits, initially with the intent of achieving beetle control. These studies provided much new information about the ecology and chemistry of host location, but they did not prove successful in protecting crops from beetle damage. Beginning in the late 1980's, pheromones were discovered in Carpophilus beetles. These were potent, male-produced aggregation pheromones, and over the next 20 years much new information was gained about their ecological properties, physiology, and novel chemistry. Importantly, the pheromones were strongly synergistic with fermenting host odors, and the combination was far more attractive than fruit-related baits or pheromones alone, which greatly improved the ability to attract these pests to traps. A practical attract-and-kill method using the pheromones and host volatiles has been developed in Australia and shown to be at least as effective as insecticides for protecting stone fruit crops.

Arthropods are sexually dimorphic. An arthropod individual usually differentiates into a male or a female. With very low frequencies, however, individuals with both male and female morphological characters have repeatedly been found in natural and laboratory populations of arthropods. Gynandromorphs (i.e., sexual mosaics) are genetically chimeric individuals consisting of male and female tissues. On the other hand, intersexes are genetically uniform (i.e., complete male, complete female or intermediate in every tissue) but all or some parts of their tissues have either a sexual phenotype opposite to their genetic sex or an intermediate sexual phenotype. Possible developmental processes (e.g., double fertilization of a binucleate egg, loss of a sex chromosome or upregulation/downregulation of sex-determining genes) and causal factors (e.g., mutations, genetic incompatibilities, temperatures or endosymbionts) for the generation of gynandromorphs and intersexes are reviewed and discussed.

Terrestrial isopods (Crustacea: Oniscidea) are important detritivores in many ecosystems. Because reproductive success and population dynamics of the Oniscidea depend on diverse biotic and abiotic environmental factors, the effects of global climate change on their biology may be significant. Although few studies have examined the relationship between climate change and population ecology in terrestrial isopods, much is known about their environment, genetics, physiology, behavior, life history, population biology, and evolutionary patterns. This review addresses the influence of biotic and abiotic environmental factors on terrestrial isopod reproduction. Significant biotic factors include microorganism-mediated sex determination, mate choice, sperm competition, maternal effects, food availability, and predation. Significant abiotic factors include temperature and moisture regimes, photoperiod, altitude, latitude, and microhabitat diversity. Studies of these factors reveal general patterns, as well as informative exceptions, in the ways different oniscid species, as well as different populations within a species, respond to environmental variation.

Bromeliads are a Neotropical plant family (Bromeliaceae) with about 2,900 described species. They vary considerably in architecture. Many impound water in their inner leaf axils to form phytotelmata (plant pools), providing habitat for terrestrial arthropods with aquatic larvae, while their outer axils provide terraria for an assemblage of fully terrestrial arthropods. Many bromeliads are epiphytic.Dominant terrestrial arthropods with aquatic larvae inhabiting bromeliad phytotelmata are typically larvae of Diptera, of which at least 16 families have been reported, but in some circumstances are Coleoptera, of which only three families have been reported. Other groups include crabs and the insect orders Odonata, Plecoptera, and Trichoptera, plus Hemiptera with adults active on the water surface. The hundreds of arthropod species are detritivores or predators and do not harm their host plants. Many of them are specialists to this habitat.Terrestrial arthropods with terrestrial larvae inhabiting bromeliad terraria include many more arachnid and insect orders, but relatively few specialists to this habitat. They, too, are detritivores or predators.Arthropod herbivores, especially Curculionidae (Coleoptera) and Lepidoptera, consume leaves, stems, flowers, pollen, and roots of bromeliads. Some herbivores consume nectar, and some of these and other arthropods provide pollination and even seed-dispersal.Ants have complex relationships with bromeliads, a few being herbivores, some guarding the plants from herbivory, and some merely nesting in bromeliad terraria. A few serve as food for carnivorous bromeliads, which also consume other terrestrial insects.Bromeliads are visited by far more species of arthropods than breed in them. This is especially notable during dry seasons, when bromeliads provide moist refugia.

Plant galls are induced by physicochemical interactions between plants and gall-inducing organisms, such as insects, mites, nematodes, fungi, bacteria and viruses. Organisms that are unable to create galls on plants, but feed on gall tissues induced by other species, are referred to as gall-attackers (gall-feeders) and include various insect orders (Thysanoptera, Hemiptera, Lepidoptera, Coleoptera, Diptera, and Hymenoptera). Gall-attacking weevils (Coleoptera) and moths (Lepidoptera) may have acquired their gall-feeding habits independently (i.e. cecidophages), whereas other gall-attacking insects, such as inquiline gall wasps (Hymenoptera) and gall midges (Diptera) may have evolved these habits from gall-inducing ancestors (i.e., inquilines). Most species of gall-attacking weevils feed only on galls (obligate cecidophages), while most gall-attacking moths feed on galls and also on ungalled or normal plant tissues (facultative cecidophages). Weevils may have acquired their gall-attacking habits independently from other types of feeding habits, such as leaf mining, seed-feeding, and bud-feeding, while moths may have acquired them from leaf-chewing and wood-boring. Studies on the effects of gall-attacking weevils on gall-inducing arthropods report a higher proportion of lethal effects than studies on effects from gall-attacking moths. Weevil larvae rarely move around food resources because they have no legs, while moth larvae can actively move among food resources using their prolegs. This difference in mobility between weevils and moth larva may be related to their differential gall-attacking behaviors and effects on gall-inducers. Cecidophages provide a model system for investigating the evolution of feeding habits and the ecology of species interactions.

This difference in mobility between weevils and moth larva may be related to their differential gall-attacking behaviors and effects on gall-inducers. Cecidophages provide a model system for investigating the evolution of feeding habits and the ecology of species interactions.","PeriodicalId":88711,"journal":{"name":"Terrestrial arthropod reviews","volume":"2 1","pages":"41-61"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/187498309X435658","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64857089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urbanisation and intensification of agriculture has led to large scale destruction of natural and semi-natural areas in Western Europe. Consequentially, the conservation of biodiversity in small landscape units has become a matter of increasing urgency. In this paper, we inventoried the arthropod diversity in roadside verges in the Netherlands and studied the relative importance of these linear elements. In addition, the occurrence of arthropods in roadside verges in other countries was studied by literature research. In the period 1998-2008, we sampled 57 roadside verges. This was mainly done by pitfall trapping, using sweeping nets and insect nets, and by sight observations. For several arthropod groups the majority of the Dutch indigenous species was sampled: ants (56% of the indigenous species), grasshoppers (53%), harvestmen (67%) and two spider families (52% and 68%). For ground beetles, weevils, butterflies, bees, hoverflies and three other spider families, values between 18–41% were found. Considering that only a minute fraction of the vast network of roadsides was sampled, these figures are remarkably high. Roadside verges are occasionally reported to act as dispersal corridors for exotic species, but this could not be confirmed for arthropods in the Netherlands. Several of the arthropod species inventoried in the Dutch verges are classified as threatened: five grasshopper and eleven bee species appear on national Red Lists and six ant species on the IUCN Red List. Also, in several other countries roadside verges in intensively used landscapes appear to offer opportunities for arthropod conservation. We conclude that, if rightly managed, roadside verges can serve as an important and valuable arthropod habitat. Therefore, we strongly recommend taking always into account the conservation of these arthropod assemblages during planning and actual management of roadside verges.
