  1. Tropical cyclone effects on insect colonization and abundance in Puerto Rico

    The knowledge of the ways in which insects disperse is important in decisions concerning their control. The dispersal of insects aided by the wind cannot be regarded as accidental and occasional but as an adaptive feature of the phylum (Johnson and Bowden 1973). Due to its location, Puerto Rico is exposed to cyclone winds that can affect the colonization and abundance...

  2. Seed and Cone Insects of Southern Pines

    Distribution maps are included for all insect species, providing at a glance each insect's expected southern distribution. Knowledge of some distributions is incomplete. Accordingly, the range maps should be used as general rather than absolute guides.

    Insect species and their pine hosts are tabulated for each of the three damage...

  3. Could tanoak mortality affect insect biodiversity? Evidence for insect pollination in tanoaks

    Tanoaks, Notholithocarpus densiflorus (Hook. & Arn.) Manos, Cannon & S. H. Oh, are being killed by sudden oak death, caused by the pathogen Phytophthora ramorum Werres, de Cock & Man in't Veld. However, very little is known about the basic ecology of the species. Here we investigate the pollination ecology of...

  4. Effects of shelterwood management on flower-visiting insects and their floral resources

    Habitat alteration can affect pollinating-insect community structure, decreasing the efficiency of pollinators on which many agricultural and natural ecosystems rely. Within the Tenderfoot Creek Experimental Forest (TCEF), located in the Little Belt Mountains of Central Montana, two different types of silvicultural techniques, even and group shelterwood, were applied...

  5. Relations between wood-inhabiting insects and fungi

    It is widely known that xylophagous insects do not usually attack healthy, resistant trees. In order to overcome these defenses, inner-bark feeding insects have developed symbiotic interrelationships with various organisms, fungi in particular. In this paper, using our own data together with that available in the literature, we analyze the forms of relationships...

  6. Effects of temperature on development, survival and reproduction of insects: Experimental design, data analysis and modeling

    The developmental response of insects to temperature is important in understanding the ecology of insect life histories. Temperature-dependent phenology models permit examination of the impacts of temperature on the geographical distributions, population dynamics and management of insects. The measurement of insect developmental, survival and reproductive responses to...

  7. Dynamics of phytophagous insects and their pathogens in Alaskan boreal forests

    Boreal forests support an array of insects, including phytophagous (plant-eating) insects, saprophagous (detritus-eating) insects, and their associated parasites, predators, and symbionts. The phytophagous species include folivorous leaf chewers and miners, phloeophagous cambial and sapwood borers, stem gallers, and root feeders. Biological diversity and distribution...

  8. Interactive effects of large herbivores and plant diversity on insect abundance in a meadow steppe in China

    The structure and dynamics of insect community in grasslands can be influenced by grazing management via altered characteristics of plant community. However, attempts to better understand the complex relationships among plants, insects, and large herbivores is still hampered largely by the interactive effects of plants, insects, and large grazers on each other. In this...

  9. Changes in aquatic insect emergence in response to whole-lake experimental manipulations of introduced trout

    1. Insects emerging from mountain lakes provide an important food source for many terrestrial predators. The amount of insect subsidy that emerges from lakes is influenced by predator composition, but predator effects could be ameliorated by greater habitat complexity. We conducted a replicated whole-lake experiment to test the effects of introduced fish...

  10. Forest litter insect community succession in clearcuts of Norway spruce

    Insects are subjected to stress in fresh clearcuts due to changes in microclimate, vegetation, and trophic links. The objective of this study was to investigate succession in litter insect communities (most abundant by number of species and individuals of all clearcut insects).

  11. Host-plant specialization in needle-eating insects of Sweden

    It has been suggested that the enormous diversity of phytochemicals within the plant kingdom makes it impossible for one and the same insect species to exploit all plant species (Dethier 1954, Fraenkel 1959). Not surprisingly, the number and diversity of host plants utilized by different phytophagous insects are highly variable, and the specific selective pressures...

  12. Bacterial growth on stream insects: potential for use in bioassessment

    Growth of filamentous bacteria (Sphaerotilus sp., Leptothrix sp.) on aquatic insects was evaluated for its usefulness as a bioindicator of detrimental nutrient levels in streams. Field measurements of insect abundance, nutrient concentrations, and incidence/ degree of bacterial growth on insects upstream and downstream of livestock pastures were made in 2 Virginia, USA...

  13. A framework for standardizing flight characteristics for separating biology from meteorology in long-range insect transport

    Once airborne during long-range transport, to what extent is the final destination determined by the biota? It is well known that a biological mechanism initiates flight and another biological mechanism terminates flight. Therefore, efforts to answer the above question should be focused on en route insect behavior.

    A strategy is proposed to isolate biology...

  14. The role of mites in insect-fungus associations

    The interactions among insects, mites, and fungi are diverse and complex but poorly understood in most cases. Associations among insects, mites, and fungi span an almost incomprehensible array of ecological interactions and evolutionary histories. Insects and mites often share habitats and resources and thus interact within communities. Many mites and insects rely on...

  15. The indirect impact of long-term overbrowsing on insects in the Allegheny National Forest region of Pennsylvania

    Overbrowsing has created depauperate plant communities throughout the eastern deciduous forest. We hypothesized these low-diversity plant communities are associated with lower insect diversity. We compared insects inside and outside a 60-year-old fenced deer exclosure where plant species richness is 5x higher inside versus outside. We sampled aboveground and litter...

    Forests in virtually all regions of the world are being affected by invasions of non-native insects. We conducted an in-depth review of the traits of successful invasive forest insects and the ecological processes involved in insect invasions across the universal invasion phases (transport and arrival, establishment, spread and impacts). Most forest insect invasions...

    The focus of investigation in this study was to consider the potential of arthropods in the dissemination of the bacterium involved in drippy blight disease, Lonsdalea quercina. Arthropod specimens were collected and tested for the presence of the bacterium with molecular markers. The bacteriumL. quercina was confirmed on 12 different insect samples fromthree orders (...

  18. Ecology of insects in California chaparral

    Studies stimulated by the International Biological Program showed total insect faunal biomass and diversity to be greatest in the spring of the year, which matches increased plant growth and flowering at this time. Ground-inhabiting beetle studies indicated the family Tenebrionidae to be overwhelmingly dominant in biomass, but the family Staphylinidae to be richest in...

  19. Silvicultural Practices in Forests of the Southern United States: Insect and Disease Considerations

    The relationship between silvicultural practices, e.g. thinning, and pest organisms (insects and diseases) has been investigated extensively in pine species but to a lesser degree in hardwoods. Of critical interest is the potential negative impact to the residual stand resulting from insect damage and diseases that develop as a consequence of silvicultural practices....
