“…pretiosum did not present genetic degeneration after being reared in the laboratory during 23 generations, and this finding can be used for evaluation of quality of this natural enemy in mass rearing programs (Boller & Chambers, 1977). This also shows that this egg parasitoid presents good adaptation to laboratory rearing in eggs of A. kuehniella .…”

“…In general, when the population is introduced into the laboratory, there will be a drop in genetic variability, due to genetic drift, selection and inbreeding during the first generations. It is only about the fifth to seventh generation that a recovery on the variability will occur due to mutation and recombination (Boller and Chambers 1977, Bartlett 1984, Leppla and Ashley 1978, Leppla and Fisher 1989, Leppla and Williams 1992, Bigler 1994.…”

“…1 does not claim to be complete but it may help to analyse the subsystems and components of a rearing system in order to elucidate the most critical points. BOLLER and CHAMBERS (1977) divided the overall quality of fruit flies reared for sterile insect release programmes into major quality components, traits and measurable parameters. The question remains whether laboratory assessed traits or attributes have a predictive value for the performance of an insect in the field.…”

The necessity for quality assessment and control in entomophagous insects and mites depends on a variety of factors that can be summarized in four main topics 1. the genetic structure of a population and the inheritance of attributes, 2. the physical rearing conditions, 3. the rearing diet (host, prey) and 4. the objective of release. The four topics are discussed with regard to their relative impact on the performance of a natural enemy. The interrelationships among the factors are presented in a diagram. The overall quality is divided into major components and single attributes and their importance is discussed. When we try to assess the quality, the problem we are concerned with is to know what, why and how to measure. The next step is the very difficult interpretation of laboratory results and their relation to the field performance. Examples of successful prediction of the field performance based on laboratory assessment of single attributes are presented. The quality control requirements relative to the rearing systems of three successfully applied parasitoids are discussed using a partition of the overall quality into the major components. The need for quality control increases with decreasing natural rearing conditions. In conclusion, each particular situation has to be analysed carefully to determine significant parameters relevant to the field performance. Zusammenfassung Zur Qualitätsbeurteilung und ‐überwachung entomophager Insekten im Rahmen der biologischen Schädlingsbekämpfung Die Notwendigkeit von Qualitätsüberwachungen bei entomophagen Insekten und Milben hängt von vielen Faktoren ab, die in vier Hauptgruppen zusammengetaßt werden können: 1. Die genetische Struktur der Population und die Vererbung einzelner Eigenschaften, 2. die physikalischen Zuchtbedingungen, 3. die Nahrung (Wirte, Beute) und 4. das Ziel und die Methode der Anwendung von Parasitoiden und Räubern. Die vier Hauptthemen werden im Hinblick auf ihre Bedeutung für die Vitalität der gezüchteten Nützlinge diskutiert. Die gegenseitigen Beziehungen zwischen den Hauptgruppen sind schematisch dargestellt. Die Gesamtqualität (Nutzleistung und Zuchteigenschaften) wird in Hauptkomponenten und einzelne meßbare Qualitätsmerkmale unterteilt, und ihre Bedeutung ist in Abhängigkeit der jeweiligen Zielsetzung der biologischen Methode besprochen. Damit Qualitätsüberwachung erfolgreich wird, muß man sich genau im klaren sein, welche Parameter warum und wie gemessen werden sollen. Ergebnisse von Labormethoden sind nur sinnvoll, wenn sic mit Felddaten erhärtet werden können. Es werden Beispiele gezeigt, bei denen die Nutzleistung im Feld aufgrund von Labormessungen erfolgreich im voraus ermittelt wurde. Die Bedürfnisse der Qualitätsüberwachung werden anband von drei erfolgreich eingesetzten Parasitoiden gezeigt. In jedem Fall sind die Haupteigenschaften je nach den Bedürfnissen und Anforderungen gewichtet. Die Beispiele verdeutlichen, daß der Bedarf an Qualitätsüberwachung im allgemeinen steigt, je künstlicher die Zuchtbedingungen im Vergleich...
