We examined the effects of anxiety and situation-specific contextual information on attentional, interpretational, and behavioural processes underpinning perceptual-motor performance as proposed by Nieuwenhuys and Oudejans (Psychological Research 76:747-759; Nieuwenhuys, Oudejans, Psychological Research 76:747-759, 2012) using an in situ task. Twelve skilled cricket batsmen played against a skilled spin bowler under conditions manipulated to induce low and high levels of anxiety and the presence of low and high levels of situation-specific context...

BACKGROUND: In Drosophila early post-meiotic spermatids, mitochondria undergo dramatic shaping into the Nebenkern, a spherical body with complex internal structure that contains two interwrapped giant mitochondrial derivatives. The purpose of this study was to elucidate genetic and molecular mechanisms underlying the shaping of this structure. RESULTS: The knotted onions (knon) gene encodes an unconventionally large testis-specific paralog of ATP synthase subunit d and is required for internal structure of the Nebenkern as well as its subsequent disassembly and elongation...

The causes and consequences of among-individual variation and covariation in behaviours are of substantial interest to behavioural ecology, but the proximate mechanisms underpinning this (co)variation are still unclear. Previous research suggests metabolic rate as a potential proximate mechanism to explain behavioural covariation. We measured the resting metabolic rate (RMR), boldness and exploration in western stutter-trilling crickets, Gryllus integer, selected differentially for short and fast development over two generations...

The genus Calliscelio Ashmead is presumed to be a diverse group of parasitoids of the eggs of crickets (Orthoptera: Gryllidae). A least one species has been found to be an important factor in depressing cricket pest populations. The New World species of Calliscelio are revised. Forty-two species are recognized, 3 are redescribed: Calliscelio bisulcatus (Kieffer), Calliscelio laticinctus Ashmead, Calliscelio rubriclavus (Ashmead), comb. n.; and 38 are described as new: Calliscelio absconditum Chen & Johnson, sp...

Female field crickets use phonotaxis to locate males by their calling song. Male song production and female behavioural sensitivity form a pair of matched frequency filters, which in Gryllus bimaculatus are tuned to a frequency of about 4.7 kHz. Directional sensitivity is supported by an elaborate system of acoustic tracheae, which make the ears function as pressure difference receivers. As a result, phase differences between left and right sound inputs are transformed into vibration amplitude differences. Here we critically tested the hypothesis that acoustic properties of internal transmissions play a major role in tuning directional sensitivity to the calling song frequency, by measuring tympanal vibrations as a function of sound direction and frequency...

Silicon (Si) has important functional roles in plants, including resistance against herbivores. Environmental change, such as increasing atmospheric concentrations of CO2, may alter allocation to Si defences in grasses, potentially changing the feeding behaviour and performance of herbivores, which may in turn impact on higher trophic groups. Using Si-treated and untreated grasses (Phalaris aquatica) maintained under ambient (400 ppm) and elevated (640 and 800 ppm) CO2 concentrations, we show that Si reduced feeding by crickets (Acheta domesticus), resulting in smaller body mass...

Thousand Island Lake (TIL) is a fragmented landscape consisting of more than 1000 land-bridge islands isolated during reservoir formation. To evaluate the effects of fragmentation and island attributes on insect populations, we examined the genetic structure of Loxoblemmus aomoriensis, a species of cricket widely distributed in TIL, and compared genetic diversity between islands samples. Population genetic analyses was conducted based on mitochondrial DNA haplotype frequencies of 10 sample islands. By comparing three island attributes with population genetic diversity reveals that island area influenced population genetic diversity (r(2 )=( )0...

In this study we describe two new species of cavicolous-straminicolous crickets for southern Brazil. Endecous chape n. sp. and E. naipi n. sp. are sympatric crickets that inhabit the Atlantic Semideciduous Forest of the Iguaçu National Park and adjacent areas. The descriptions were based on morphological characters, mainly from male genitalia and tegmina of adult males. Furthermore, we describe the chromosomes and the calling song of one of the new species, E. chape n. sp., presenting a discussion about the morphology of the phallic complex of Endecous and a distribution map for the species of the genus...

BACKGROUND: When an athlete has more than one injury over a time period, it is important to determine if these are related to each other or not. The subsequent injury categorisation (SIC) model is a method designed to consider the relationship between an index injury and subsequent injury(ies). OBJECTIVE: The primary aim was to apply SIC to longitudinal injury data from two team sports: rugby union and cricket. The secondary aim was to determine SIC inter-rater reliability...

The use of edible insects has a long history in China, where they have been consumed for more than two thousand years. In general, the level of acceptance is high for the consumption of insects in China. Many studies on edible insects have been conducted in the last twenty years, and the scope of the research includes the culture of entomophagy and the identification, nutritional value, farming and breeding of edible insects, in addition to food production and safety. Currently, 324 species of insects from 11 orders are documented that are either edible or associated with entomophagy in China, which include the common edible species, some less commonly consumed species, and some medicinal insects...

OBJECTIVES: The fibula transmits loads within the lower limb of hominids. The few studies of variation in the cross-sectional geometric (CSG) properties of the fibula have established differences in its rigidity among groups engaged in distinct habitual loading activities. This study adds to this research by considering the relationship between CSG properties and the anatomical position of the fibula relative to the tibia among groups with differences in documented activity patterns. MATERIAL AND METHODS: We used pQCT scans taken at 50% of the length of the lower leg in 83 healthy young adult collegiate-aged individuals divided into five activity groups: runners, swimmers, cricketers, field hockey players, and non-athletes...

Distance estimation plays an important role in location-based services, which has become very popular in recent years. In this paper, a new short range cricket sensor-based approach is proposed for indoor location applications. This solution uses Time Difference of Arrival (TDoA) between an optical and an ultrasound signal which are transmitted simultaneously, to estimate the distance from the base station to the mobile receiver. The measurement of the TDoA at the mobile receiver endpoint is proportional to the distance...

We present a rare case of primary tuberculous tenosynovitis in a young patient with an acute history of non-penetrating traumatic injury. The patient had recently visited Pakistan and presented with sudden onset pain at the base of their right fifth digit after trying to catch a cricket ball. A provisional diagnosis of haematoma was made; however, ultrasonography revealed a mass attached to the A2 pulley. Surgical excision followed by histological examination and culture identified Mycobacterium Tuberculosis infection...

Cricket is one of the world's most popular sports, followed by hundreds of millions of people. It can be dangerous, played with a hard ball flying at great velocities, and accidents have occasionally been fatal. Traditionally, cricket has been played during the day, using a dark red ball. Since the late 1970s, a shorter form of one-day cricket has been played both during the day and at night under floodlights. To overcome visibility issues, one-day cricket uses a white ball, and players wear coloured clothing...

Recent theory predicts that the magnitude of sexual antagonism should depend on how well populations are adapted to their environment. We tested this idea experimentally by comparing intersexual genetic correlations for adult survival in pedigreed populations of Southern field crickets (Gryllus bimaculatus) raised on naturally balanced (free-choice) vs. imbalanced (protein-deprived) diets. We tested for 1) sex differences in nutritional intake and preference, 2) sex-specific effects of protein deprivation on survival and 3) diet-dependence of the level of sexual antagonism...

The non-consumptive effects of predation contribute to reduce preys' fitness. In this way, predation imposes a cost to animals, not only through direct consumption, but also as an energetic cost. One way used to estimate this cost in the past has been to measure the production of CO2 to estimate the change in metabolic rate because of predation. It has been proposed that this change is mediated by the insect stress neurohormone octopamine. Here we study the change in metabolic rate of the black field cricket (Teleogryllus commodus), and how the production of CO2 varies when a chemical cue from a sympatric predator is added...

INTRODUCTION: Fractures of the proximal tibial epiphysis rare. It has been estimated that fractures of the upper tibial epiphysis account for 0.5-3.1% of all epiphyseal injuries. Who had no neurovascular deficit, with fixed extension deformity at the left knee was treated early with closed reduction techniques. CASE REPORT: We present a case of a 16-year-old boy who while playing cricket on the road was hit by a car. The patient presented in emergency room with extremely swollen knee and soft tissue swelling (hemarthrosis), he was unable to lift his leg actively due to severe pain because of hamstrings spasm, and he had no wound over his left knee and had no other associated injuries...

Recently, the benefits of entomophagy have been widely discussed. Due to western cultures' reluctance, entomophagy practices are leaning more towards incorporating insects into food products. In this study, whole crickets (Gryllodes sigillatus) were hydrolyzed with alcalase at 0.5, 1.5, and 3.0% (w/w) for 30, 60, and 90min. Degree of hydrolysis (DH), amino acid composition, solubility, emulsion and foaming properties were evaluated. Hydrolysis produced peptides with 26-52% DH compared to the control containing no enzyme (5% DH)...

The lumbar spine is subjected to considerable stress during many athletic efforts. The purpose of this study was to assess the effects of physiological loading on the lumbar spine in national male players of different games, which may be predictive of the future development of low back pain and injury symptoms. Thirty-four national players (12 cricket players, 12 field hockey players, and 10 basketball players) underwent magnetic resonance imaging, and selected geometric variables including intervertebral disc angles, the Farfan ratio, the lumbar body index, the compression deformity ratio, the biconcave deformity ratio and the anterior wedge deformity ratio were measured using KINOVEA-0...
