  • Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015)
    Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015) By Richard Henderson Research Ecologist, WI DNR Bureau of Science Services Summary This is a preliminary list of insects that are either well known, or likely, to be closely associated with Wisconsin’s original native prairie. These species are mostly dependent upon remnants of original prairie, or plantings/restorations of prairie where their hosts have been re-established (see discussion below), and thus are rarely found outside of these settings. The list also includes some species tied to native ecosystems that grade into prairie, such as savannas, sand barrens, fens, sedge meadow, and shallow marsh. The list is annotated with known host(s) of each insect, and the likelihood of its presence in the state (see key at end of list for specifics). This working list is a byproduct of a prairie invertebrate study I coordinated from1995-2005 that covered 6 Midwestern states and included 14 cooperators. The project surveyed insects on prairie remnants and investigated the effects of fire on those insects. It was funded in part by a series of grants from the US Fish and Wildlife Service. So far, the list has 475 species. However, this is a partial list at best, representing approximately only ¼ of the prairie-specialist insects likely present in the region (see discussion below). Significant input to this list is needed, as there are major taxa groups missing or greatly under represented. Such absence is not necessarily due to few or no prairie-specialists in those groups, but due more to lack of knowledge about life histories (at least published knowledge), unsettled taxonomy, and lack of taxonomic specialists currently working in those groups.

In addition, this species is a regulatory concern in the USA. In this work, we investigated the influence of trap design, trap height, and trap color on pheromone trap catches of C. decolora males in cruciferous crops. Additionally, we investigated the seasonal dynamics of C. decolara for 3 yr. The water-trap captured a significantly higher number of males compared to the jug trap and the Scentry® Heliothis trap. There were no significant differences between in the number of males captured by traps positioned at 0.5, 1, and 1.5 m above ground level. There was also no an interaction between trap design and trap height. Green water-traps captured more males than red water-traps, however, the catches of red water-traps were intermediate and not significantly different from those captured by yellow, blue, and brown water-traps. A total of 6,978 C. decolora males were captured during the 3 yr of trapping. The overall distribution of trap captures over the season was unimodal, with a distinctive peak in trap catches occurring between Mar and Apr.

  • Errata and First Update to the 2010 Checklist of the Lepidoptera Of
    Errata and first uppppdate to the 2010 checklist of the Lepidoptera of Alberta Gregory R. Pohl, Jason J Dombroskie, Jean‐François Landry, Charles D Bird, and Vazrick Nazari lead author contact: [email protected] Introduction: Since the Annotated list of the Lepidoptera of Alberta was published in March 2010 (Pohl et al. 2010), a few typographical and nomenclatural errors have come to the authors' attention, as well as three erroneous AB records that were inadvertently omitted from that publication. Additionally, a considerable number of new AB species records have been brought to our attention since that checklist went to press. As expected, most are microlepidoptera. We detail all these items below, in what we hope will be a regular series of addenda to the AB list. If you are aware of further errors or additions to the AB Lepidoptera list, please contact the authors. Wit hin the NidNoctuoidea, there are a few minor iiiinconsistencies in the order of species wihiithin genera, and in the order of genera within tribes or subtribes, as compared to the sequence published by Lafontaine & Schmidt (2010). As well, the sequence of tribes in the AB list does not exactly match that of Lafontaine & Schmidt (2010), particularly in the Erebinae. We are not detailing those minor differences here unless they involve a move to a new genus or new higher taxonomic category. Errata: Abstract, p. 2, line 10, should read "1530... annotations are given" 41 Nemapogon granella (p. 55). Add Kearfott (1905) to the AB literature records. 78 Caloptilia syringella (p. 60). This species should be placed in the genus Gracillaria as per De Prins & De Prins (2005).

Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world.

We report chronological and physiological age-based survival curves for a potentially in- vasive noctuid, recently described as Copitarsia corruda Pogue & Simmons, collected from Peru and reared on asparagus at six constant temperatures between 9.7 and 34.5C. Copitarsia spp. are not known to occur in the United States but are routinely intercepted at ports of entry. Chronological age survival curves differ significantly among temperatures. Survivorship at early age after hatch is greatest at lower temperatures and declines as temperature increases. Mean longevity was 220 (+13 SEM) days at 9.7C. Physiological age survival curves constructed with developmental base temperature (7.2C) did not correspond to those constructed with a senescence base temperature (5.9C). A single degree day survival curve with an appropriate temperature threshold based on senescence adequately describes survivorship under non-stress temperature conditions (5.9–24.9C).

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.
