Ecology of the field cricket (Gryllidae: Orthoptera) in farmland: the importance of livestock grazing
The field cricket Gryllus campestris used to be very common throughout Europe, but in recent decades its population has declined. We study ecology and behavior of crickets near the Odolanów, Poland, between 2009 2011, with emphasis on the effects of grazing of cattle and horses on insects population. We compared the number of burrows per square meter on both grazed and non-grazed areas and exam...
متن کاملMovement analyses of wood cricket ( Nemobius sylvestris) (Orthoptera: Gryllidae).
Information on the dispersal ability of invertebrate species associated with woodland habitats is severely lacking. Therefore, a study was conducted examining the movement patterns of wood cricket (Nemobius sylvestris) (Orthoptera: Gryllidae) on the Isle of Wight, UK. Juvenile (i.e. nymphs) and adult wood crickets were released and observed over time within different ground surface substrates. ...
متن کاملSexual dimorphism in cuticular hydrocarbons of the Australian field cricket Teleogryllus oceanicus (Orthoptera: Gryllidae).
Sexual dimorphism is presumed to reflect adaptive divergence in response to selection favouring different optimal character states in the two sexes. Here, we analyse patterns of sexual dimorphism in the cuticular hydrocarbons of the Australian field cricket Teleogryllus oceanicus using gas chromatography. Ten of the 25 peaks found in our chromatographs, differed in their relative abundance betw...
متن کاملThe Field Cricket Gryllus assimilis and Two New Sister Species (Orthoptera: Gryllidae)
Inpreparation for revisionary studiesofwesternU.S.GryllusÞeldcrickets, someeastern U.S. names for species with supposed transcontinental distributions must be resolved. One such species, Gryllus assimilis (F.), as currently characterized, occurs in the West Indies, Brazil, Central America, and Mexico, and in Þve of the southernmost U.S. states. Our studies of calling songs and morphology indica...
متن کاملMale Responses to Conspecific Advertisement Signals in the Field Cricket Gryllus rubens (Orthoptera: Gryllidae)
In many species males aggregate and produce long-range advertisement signals to attract conspecific females. The majority of the receivers of these signals are probably other males most of the time, and male responses to competitors' signals can structure the spatial and temporal organization of the breeding aggregation and affect male mating tactics. I quantified male responses to a conspecifi...
