The feather mite Plesialges mimus Trouessart, 1919, briefly described from the White-browed Babbler Pomatostomus superciliosus (Vigors & Horsfield) (Passeriformes: Pomatostomidae), is only species of genus 1919. In this work, I redescribe based on type specimens, transfer it into Hemialges 1895, and provide with valid name (Trouessart, 1919) comb. n. syn. synonymized Hemialges. A new diagno...

the spider mite, t. turkestani, is considered as one of the most important polyphagous pests of many crops. its reproductive ability, developmental time, preimaginal mortality and reproduction rate were determined on kidney bean at 20, 25 and 30°c,70±5% rh and 16l:8d. female longevity and immature developmental period (6.74 and 5.8 days, respectively) were shorter at 30°c than at 20 and 25°c. t...

Alarm-calling behaviour is common in many species that suffer from predation. While kin selection or reciprocal altruism are typically invoked to explain such behaviours, several authors have conjectured that some alarm calls may instead be costly signals sent by prey to inform approaching predators that they have been detected. We develop a general game-theoretical model, the watchful babbler ...
