7.3. Quality control procedures
Development of insects is a dynamic process influenced by a complex of biotic and abiotic factors. Since biodegradation of waste by fly larvae depends on controlled mass-rearing of these insects, suitable quality control procedures should be established in the biodegradation facilities to avoid deterioration of fly strain which could result in a collapse of waste processing.
Routine procedures should involve continuous monitoring of the health and egg productivity of adult fly colony, as well as basic parameters of larval development and physicochemical parameters of end products. Additionally, laboratory populations should be periodically out-crossed to reduce problems (decreased fitness levels) associated with continuous inbreeding (Reed and Bryant, 2001 and Day et al., 2003).
The flies are susceptible to a number of pathogens, particularly entomopathogenic fungi, which can threaten an adult colony (Čičková et al., 2012b). Decreased fecundity of adults is often indicative of problems encountered during larval development, e. g. poisoning (Diener et al., 2011a), inadequate environmental conditions and/or food supply of adults (Pastor et al., 2011).
