Water immersion tolerance by larval instars of stable fly, Stomoxys calcitrans, L1758 (Diptera: Muscidae) impairs the fitness performance of their subsequent stages

open access: yesBMC Ecology and Evolution, 2021
Background In holometabolous insects, environmental factors experienced in pre-imaginal life stages affect the life-history traits within that stage and can also influence subsequent life stages.

Study of some biological aspects of the blowfly Chrysomya albiceps (Wiedemann 1819) (Diptera: Calliphoridae) in Jeddah, Saudi Arabia

open access: yesEgyptian Journal of Forensic Sciences, 2016
We reared Chrysomya albiceps (Wiedemann 1819) unadult stages (first larval instar, second larval instar, third larval instar and pupal stage) under four constant temperatures. Results proved that increasing temperature from 20 to 25, 30 and 35 °C reduced

SUPERNUMERARY LARVAL INSTARS IN CYCLORRHAPHOUS DIPTERA

open access: yesThe Biological Bulletin, 1972
1. The developmental program for metamorphosis is determined in third instar larvae of Calliphora and Sarcophaga very early after ecdysis. The process is activated by feeding and can be delayed for many days by starvation.2. High doses of ecdysterone (20 µg per larva) injected just after ecdysis or in starved larvae cause a precocious molt and the ...
