Males of many animal species show intraspecific disputes for mating territories that range from displays without physical contact to physical fights with risk of injury. This variation motivated the proposition of different models that suggest possible rules used by rivals to decide the contest winner. To evaluate those models, it is necessary to identify how males behave during the fight and t...

The aquatic insect fauna of salt marshes is poorly characterized, with the possible exception of biting Diptera. Aquatic insects play a vital role in salt marsh ecology, and have great potential importance as biological indicators for assessing marsh health. In addition, they may be impacted by measures to control mosquitoes such as changes to the marsh habitat, altered hydrology, or the applic...

For eleven species of sympatric libellulids, male mean mass was positively correlated with wing aspect ratio, wing loading, and mean perch height. We tested the hypo theses that perch height selection was governed by interspecific competition or biomechanical responses to increased wind speed at higher perches. Although larger odonates might prefer higher perches to offset their increased wing ...

A short investigation was devised by Department of Agricultural Entomology, Tamil Nadu University, Coimbatore in 2022 to document the arthropod composition sugarcane (Saccharum officinarum L.) ecosystem. Arthropod fauna collected from ecosystem farmers’ field at Puthur district, weekly intervals. Totally, 2,310 individuals subclass Pterygota were and among them most specimens belonged Exopteryg...
