A. Mahdi Abstract Original Research Article The present study was done to assess the species abundance, monthly occurrence and diversity of cricket fauna (Orthoptera: Ensifera) in Rajshahi City, Bangladesh. A total number of 283 individuals of cricket fauna were collected and they were identified into three families, six genera and seven species. The collected specimens belonged to three families such as Gryllidae (166), Tettigoniidae (59) and Gryllotalpidae (58). The seven species and their relative abundance were viz. Gryllus texensis (36.40%), Gryllus campestris (18.37%), Lepidogryllus comparatus (3.89%), Neoconocephalus palustris (9.89%), Scudderia furcata (4.95%), Montezumina modesta (6.01%) and Gryllotalpa gryllotalpa (20.49%). Among them, highest population with dominance was Gryllus texensis (103) and lowest population was Lepidogryllus comparatus (11). Among the collected species, the status of Gryllus texensis, Gryllus campestris and Gryllotalpa gryllotalpa were very common (VC); Neoconocephalus palustris and Montezumina modesta were fairly common (FC) and Lepidogryllus comparatus and Scudderia furcata were considered as rare (R). Base on monthly occurrence 2 species of cricket were found throughout 12 months, 2 were 9-11 months, 2 were 6-8 months and 1 was 3-5 months. -
Mole Crickets Scapteriscus Spp
Mole Crickets Scapteriscus spp. Southern mole cricket, Scapteriscus borellii Tawny mole cricket, Scapteriscus vicinus DESCRIPTION OF INSECT All stages live in the soil and are rarely see on the surface. Immature stage Nymphs of both species are similar in appearance to adults, but lack wings. Nymphs proceed through 8-10 instars ranging in size from 0.2 to 1.25 inches in length. Each instar is progressively larger with wing buds apparent on later instars. Color varies from gray to brown. Pronotum (large shield behind head) with distinctive mottling or spots, depending on species and location. Mature stage Adults are somewhat cylindrically shaped, light colored crickets 1.26 to 1.38 inches in length. Adults have two pairs of wings, but only fly at night during two brief flight periods in fall and early spring. Spring flights are generally more extensive than fall flights. Damaging stage(s) Both nymphs and adults cause damage Predictive models (degree day, plant phenology, threat temperatures, other) Eggs being to hatch at threat temperatures of 65° F and higher (spring/early summer in most locations). Egg-laying and hatch timing are affected by soil moisture. Threat temperatures can be used to trigger preventive treatments. See the article, “Threat temperatures” for more information. Preventive treatments should be applied prior to egg-hatch (early June) or at the time of peak hatch (last week of June, first week of July in most years and locations). Weekly soap flushes in June and early July is the best method to determine when hatch is occurring, and the best time to treat. -

Populations are known to currently occupy fragmented prairie sites in Oklahoma, Arkansas, Kansas and Missouri, including The Nature Conservancyʼs Tallgrass Prairie Preserve in north central Oklahoma. Prairie mole cricket populations were surveyed at this site and at another site in Craig County, OK during the spring of 2005 and 2006, using the male cricketʼs acoustic call to locate advertising aggregations of males. Five males from one large aggregation were removed in a study to describe (1) the hearing thresholds across the callʼs range of frequencies, (2) the distances over which the higher harmonic components of the maleʼs calls are potentially detectable, (3) the speciesʼ sensitivity to ultrasound and (4) the spatio-auditory dynamics of the prairie mole cricket lek. Results indicate that G. major has a bimodal pattern of frequency tuning, with hearing sensitivities greatest at the 2 kHz carrier frequency (41 dB SPL) and declining through the callʼs frequency range (84 dB at 10 kHz). -

Food composition and food consumption of the Rook Corvus frugi legus in agrocoenoses in Poland. Acta orn. 17: 227-256. Throughout the year Books take vegetable and animal food in nearly equal proportions. Vegetable food consists mainly of grains, and animal food of insects. The author has used a new method for estimating weight proportions of different food items, a method which takes into consideration digestion time for different food types. A high percentage of pests have been found in the Eook’s diet. One Rook takes annually about 13 kg of grain and 16 kg of animal food. J.

Folk Taxonomy, Nomenclature, Medicinal and Other Uses, Folklore, and Nature Conservation Viktor Ulicsni1* , Ingvar Svanberg2 and Zsolt Molnár3
Ulicsni et al. Journal of Ethnobiology and Ethnomedicine (2016) 12:47 DOI 10.1186/s13002-016-0118-7 RESEARCH Open Access Folk knowledge of invertebrates in Central Europe - folk taxonomy, nomenclature, medicinal and other uses, folklore, and nature conservation Viktor Ulicsni1* , Ingvar Svanberg2 and Zsolt Molnár3 Abstract Background: There is scarce information about European folk knowledge of wild invertebrate fauna. We have documented such folk knowledge in three regions, in Romania, Slovakia and Croatia. We provide a list of folk taxa, and discuss folk biological classification and nomenclature, salient features, uses, related proverbs and sayings, and conservation. Methods: We collected data among Hungarian-speaking people practising small-scale, traditional agriculture. We studied “all” invertebrate species (species groups) potentially occurring in the vicinity of the settlements. We used photos, held semi-structured interviews, and conducted picture sorting. Results: We documented 208 invertebrate folk taxa. Many species were known which have, to our knowledge, no economic significance. 36 % of the species were known to at least half of the informants. Knowledge reliability was high, although informants were sometimes prone to exaggeration. 93 % of folk taxa had their own individual names, and 90 % of the taxa were embedded in the folk taxonomy. Twenty four species were of direct use to humans (4 medicinal, 5 consumed, 11 as bait, 2 as playthings). Completely new was the discovery that the honey stomachs of black-coloured carpenter bees (Xylocopa violacea, X. valga)were consumed. 30 taxa were associated with a proverb or used for weather forecasting, or predicting harvests. Conscious ideas about conserving invertebrates only occurred with a few taxa, but informants would generally refrain from harming firebugs (Pyrrhocoris apterus), field crickets (Gryllus campestris) and most butterflies. -

Insect resources are vast and diverse due to their enormous diversity. The exploitation and utilization of insect resources is broadly classified into four different categories. The first category is the insects of industrial resources. This level includes the utilization of silk worm, honeybee, lac insect, dye insect, and aesthetic insect. The second category is the utilization of insects for edible and therapeutic purposes. Insects are high in protein and many are rich sources of vitamins and minerals. The third category is the use of insects in forensic investigation. By analyzing the stages of succession of insects at first, rough estimation of the postmortem intervals can be done. The fourth category is the insects of ecological importance. Many insect species act as potential predators and parasites of destructive pests of insect order Lepidoptera, Diptera, and Orthoptera. Insects are also used as bioindicator to assess the cumulative effects of environmental stressors such as pollutants. -
Phylogeny of Ensifera (Hexapoda: Orthoptera) Using Three Ribosomal Loci, with Implications for the Evolution of Acoustic Communication

Jost a,*, K.L. Shaw b a Department of Organismic and Evolutionary Biology, Harvard University, USA b Department of Biology, University of Maryland, College Park, MD, USA Received 9 May 2005; revised 27 September 2005; accepted 4 October 2005 Available online 16 November 2005 Abstract Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals pro- duced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most ensiferan families, and the superfamily Gryllacridoidea which would include Stenopelmatidae, Anostostomatidae, Gryllacrididae, and Lezina. Schizodactylidae was recovered as the sister lineage to Grylloidea, and both Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than has been suggested by prior studies. The ambidextrously stridulating haglid Cyphoderris was found to be basal (or sister) to a clade that contains both Grylloidea and Tettigoniidae. Tree comparison tests with the concatenated molecular data found our phylogeny to be significantly better at explaining our data than three recent phylogenetic hypotheses based on morphological characters. A high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures. In contrast to prior evolutionary hypotheses based on most parsi- monious ancestral state reconstructions, we propose that tegminal stridulation and tibial tympana are ancestral to Ensifera and were lost multiple times, especially within the Gryllidae. -

The acoustic chambers of the European mole cricket Gryllotalpa gryllotalpa (L., 1758) were studied in the north-west of Iran. Observations showed that all the calling burrows in this area had one horn shape entrance and branching tunnels beyond the bulb (the site of the head and thorax of insect in calling position). The patterns of these burrows were alike; however, the sizes of different parts of tunnels were dependent on the dimension of males.
