Dolbear's Law - Wikipedia 14/12/17 22:21
Dolbear's law - Wikipedia 14/12/17 22:21 Dolbear's law Dolbear's law states the relationship between the air temperature and the rate at which crickets chirp.[1][2] It was formulated by Amos Dolbear and published in 1897 in an article called "The Cricket as a Thermometer".[3] Dolbear's observations on the relation between chirp rate and temperature were preceded by an 1881 report by Margarette W. Brooks,[n 1] although this paper went unnoticed until after Dolbear's publication.[2] Dolbear did not specify the species of cricket which he observed, although subsequent researchers assumed it to be the snowy tree cricket, "Oecanthus niveus".[1] [2] However, the snowy tree cricket was misidentified as O. niveus in early reports and the correct scientific name The tree cricket Oecanthus fultoni for this species is Oecanthus fultoni.[4] The chirping of the more common field crickets is not as reliably correlated to temperature—their chirping rate varies depending on other factors such as age and mating success. In many cases, though, the Dolbear's formula is a close enough approximation for field crickets, too. Contents 1 Equations 2 In popular culture 3 See also 4 Notes 5 References Equations Dolbear expressed the relationship as the following formula which provides a way to estimate the temperature TF in degrees Fahrenheit from the number of chirps per minute N60: This formula is accurate to within a degree or so when applied to the chirping of the field cricket. Counting can be sped up by simplifying the formula and counting the number of chirps produced in 15 seconds ( ): https://en.wikipedia.org/wiki/Dolbear%27s_law Pagina 1 di 3 Dolbear's law - Wikipedia 14/12/17 22:21 Reformulated to give the temperature in degrees Celsius (°C), it is: A shortcut method for degrees Celsius is to count the number of chirps in 8 seconds ( ) and add 5 (This is fairly accurate between 5 and 30°C): The above formulae are expressed in terms of integers to make them easier to remember—they are not intended to be exact. -

Chapter 9. Orthoptera of the Grasslands of British Columbia and the Yukon Territory
271 Chapter 9 Orthoptera of the Grasslands of British Columbia and the Yukon Territory James Miskelly Research Associate, Royal BC Museum 675 Belleville St., Victoria, B.C., V8W 9W2 Abstract. Of all the habitats available in British Columbia and the Yukon Territory, grasslands support by far the greatest diversity, 87 species, of Orthoptera. Although most of these species have broad distributions in western North America, 23 are not found in other provinces or territories and one is endemic to Yukon. The rarest and most restricted species are those that have their Canadian ranges limited to the arid shrub-steppe in southern British Columbia. Although most Orthoptera in British Columbia and Yukon grasslands are phytophagous, few cause economic damage to cultivated crops. The Orthoptera of British Columbia and Yukon are relatively well studied thanks to the work of a series of researchers over the last century. However, basic inventory and ecological study is needed throughout the region. Since 2005, Orthoptera in British Columbia and Yukon have received renewed attention in fi eld collections and basic research. Résumé. De tous les habitats disponibles en Colombie-Britannique et au Yukon, ceux des prairies présentent de loin la plus grande diversité d’orthoptères, soit 87 espèces. La plupart de ces espèces sont largement répandues dans l’ouest de l’Amérique du Nord, mais 23 d’entre elles sont inconnues dans les autres provinces et territoires, et une est endémique du Yukon. Les espèces les plus rares et les plus restreintes sont celles dont l’aire de répartition canadienne se limite à la steppe arbustive aride du sud de la Colombie-Britannique. -
Effects of Temperature on Chirp Rates of Tree Crickets (Orthoptera: Oecanthidae)
70 S.-Afr. Tydskr. Dierk. 1992,27(2) Effects of temperature on chirp rates of tree crickets (Orthoptera: Oecanthidae) A.B. Toms Department of General Entomology, Transvaal Museum, P.O. Box 413, Pretoria, 0001 Republic of South Africa Received 2 October 1991; accepted 3 February 1992 The relationship between temperature and chirp rate is described for three African tree crickets, Oecanthus capensis, 0. karschi and O. sycomorus. Knowledge of the variation in the chirp rates of 0. karschi and 0. capensis makes it possible to discriminate between the songs of these species with a stopwatch. Their songs can also be used to estimate air temperature. When signals like cricket songs change with temperature, the response may also be affected. Some problems associated with temperature dependent communication systems are discussed. Die verhouding tussen temperatuur en t,jirptempo word beskryf vir drie Afrika boomkrieke, Oecanthus capensis, 0. karschi en O. sycomorus. Kennis van die verskille in die tjirptempo's van O. karschi en O. capensis maak dit moontlik om tussen die sang van die twee spesies te onderskei met 'n stophoriosie. Hulle sang kan oak gebruik word om lugtemperatuur te meet. Wanneer seine soos kriekklanke verander met temperatuur, kan die reaksies ook be"invloed word. Sommige probleme geassosieer met temperatuur afhanklike kommunikasie-stelses, word bespreek. Surprisingly little is known about the effects of temperature Several studies have been made on the relationship on rates within poikilothenn nervous systems (Walker between temperature and chirp rate of the American snowy 1975). Since poikilothenn metabolic rates generally increase tree cricket Oecanthus fultoni (e.g. Brooks 1882; Dolbear with temperature, pulse rates and chirp rates of the calling 1897; Block 1966; Walker 1969). -

Snowy Tree Cricket
Pest Profile Photo credit: Joseph Berger, Bugwood.org Common Name: Snowy Tree Cricket Scientific Name: Oecanthus fultoni Order and Family: Orthoptera, Gryllidae Size and Appearance: Adults are about ¾ inch long and have slender bodies. They have translucent/light green wings and a light green body. Eggs are laid in the stems and canes of host plants. The chirping rate of the snowy tree cricket is given by the equation T=50+(N-40)/4, where T is temperature in Fahrenheit and N is chirps per minute. Length (mm) Appearance Egg 3mm Pale yellow in color; kidney shaped egg; laid in stems and canes of plants; females drill a tiny hole in the twig to lay eggs and then seal the hole with chewed plant tissue. Larva/Nymph The nymphs resemble adults; develop wing buds slowly; pale almost white in color; slender. Adult 15-18mm Translucent light green wings, light green body; pale legs and antennae; have oval black marking on first and second antennae segments; long slender body and small head; antennae longer then body; one generation a year. Pupa (if applicable) Type of feeder (Chewing, sucking, etc.): Nymphs and Adults: Chewing Host plant/s: Trees and shrubs, especially caneberries and fruit trees. Can also feed on apple, plum, peach, and cherry. Description of Damage (larvae and adults): Adults and nymphs feed on leaves. Feeding on leaves does little damage. Calloused areas, susceptibility to stem breakage, and fungal problems can result when females lay eggs in host plants. Adults can feed on ripe fruits, eating holes in them that may cause rot. -
Common Buckthorn, Rhamnus Cathartica L.: Available Feeding Niches and the Importance of Controlling This Invasive Woody Perennial in North America
Common buckthorn, Rhamnus cathartica L.: available feeding niches and the importance of controlling this invasive woody perennial in North America M.V. Yoder,1 L.C. Skinner1,2 and D.W. Ragsdale1 Summary Common buckthorn, Rhamnus cathartica L., an invasive woody perennial of northern hardwood forests in North America, has been targeted for classical biological control, and research has been underway since 2001. In support of biological control research, a survey was conducted for insects associated with common buckthorn in a portion of its introduced range in the state of Minnesota. This survey provides baseline information on available feeding niches for potential control agents of common buckthorn and identifies the natural enemy community that could potentially interfere with agent establishment. In 2 years of sampling, 356 species representing 111 families and 13 orders were collected from common buckthorn in Minnesota. There was no significant defoliation observed at any of the study sites. We surmise that ample feeding niches are available given that most herbivores collected can be classified as generalists. However, the abundance of parasitoids and predators may hinder establishment of potential biological control agents. Further research is needed to determine if biotic resistance could play a significant role in preventing establishment of herbivores in a classical biological control programme for common buckthorn in North America.

III. the Orthoptera (Grasshoppers and Crickets)
United States Department of Invertebrates of the Agriculture Forest Service H.J. Andrews Experimental Forest, Pacific Northwest Research Station Western Cascades, Oregon: Research Note PNW-443 III. The Orthoptera (Grasshoppers May 1986 and Crickets) David C. Lightfoot F I L E C l } | Abstract An inventory of Orthoptera (grasshoppers and crickets) at the H.J. Andrews Experimen- tal Forest, near Blue River, Oregon, was conducted to determine the species present and ecological relationships. A key for identification and an annotated list are presented. From qualitative assessments of successional habitat relationships, generalized species associations of forest Orthoptera are proposed, and their responses to forest succession are predicted. Keywords: Invertebrata, keys (invertebrata), checklists (invertebrata), Oregon (H.J. Andrews Exp. For.). Introduction Orthoptera are important primary consumers in many terrestrial ecosystems (Odum and others 1962, Rodell 1977, Uvarov 1977). In temperate regions they are especially prevalent in grassland and scrub formations (Barnum 1964, Campbell and others 1974, Otte 1976). Relatively few Orthoptera occur in temperate forests of the Pacific Northwest and little is known about species composition or about orthopteran community patterns or processes. This study was conducted to inventory the Orthoptera of the H.J. Andrews Experimental Forest (HJA) (a long-term ecological research site of the National Science Foundation), Willamette National Forest, near Blue River, Oregon, and to provide information about and identify those species that occur there. Analysis of long-term ecological trends is of primary concern at the HJA. To determine how orthopteran communities change over time, patterns of habitat associations were qualitatively assessed for a series of sites at different stages of vegetational succession.
