Development and longevity of Nosopsyllus laeviceps kuzenkovi (Siphonaptera) from Inner Mongolia under laboratory conditions.
The development and longevity of Nosopsyllus laeviceps kuzenkovi (Yagubyants), a major plague vector among sylvan and campestral rodents in Inner Mongolia, China, was studied under controlled laboratory conditions of 11, 14, 17, 20, 23, 26, 29, and 35 C at 76% relative humidity (R.H.), and 32, 53, 76, 87, and 100% at 23 C. Development from egg to adult was shortest (21-23 days) under favorable conditions of 26 C at 76% R.H., but maximum survival to adulthood (84%) occurred at 23 C. Average longevity was 13.25 days (13.70 in females and 12.80 in males) at 17 C and 76% R.H.; it was longer at cooler and shorter at warmer temperatures. Findings provided experimental data that helped clarify seasonal fluctuations, summer mortality, generation cycles, and survival of compared flea species from Russia, Azerbaidzhan, and China.
