Дыхание калифорнийской щитовки (Quadraspidiotus perniciosus Comst.) (Insecta, Coccoidea)

Abstract

Respiration of Quadraspidiotus perniciosus Comst was studied at different stages of ontogenesis. The lowest oxygen intake and respiratory coefficient were observed in larvae of age I at the diapausal state. Both indices grow in feeding specimens of Q. perniciosus. The highest level of gas exchange was observed in the insects just after moults and in a winged male.
