“…The emerging adults are then forced into an artiÞcial environment that differs from their natural conditions (Moore et al 1985). This colonization process is the basis of mass-rearing operations (Ochieng-Odero 1994).…”

The demographic changes in Anastrepha obliqua (Macquart) (Diptera: Tephritidae) throughout laboratory colonization were characterized over the course of 11 generations. Four significant changes were determined. The first change was a reduction in the preoviposition period from the G(p) to G(1). The second was that wild female flies had difficulty ovipositing in an artificial substrate, yielding the lowest fecundity rates observed throughout the experiment. The third significant change was a decrease in longevity and life expectancy from G(p) to G(1), which then continued to decrease with successive generations. This resulted in a lab strain with high fecundity limited to a short period of oviposition. The last significant change was a reduction in larval and pupal weight. In addition, larval recovery decreased from G(p) to G(1) but displayed rapid recovery over the course of generations. There was no change in adult emergences for all generations, and flight ability increased with successive generations. These changes were correlated with demographic parameters, indicating that the increased investment in early age reproduction incurs costs such as a reduction in life expectancy or fecundity later in life. This trend was also correlated with an increase in early fecundity and reduction in the oviposition period.

“…The second selection pressure is the artiÞcial diet fed to the larvae, consisting mainly of a mixture of yeast, sugar and wheat bran, rather than fruit (Cayol 2000). Moreover, temperature, humidity, and light in mass-rearing facilities are constant and differ from the variable outdoor environment (Ochieng-Odero 1994, Artiaga-Ló pez et al 2004.…”

“…However, mating compatibility represents a very different issue, because male courtship behavior is altered during the mass-rearing process Eberhard 1998, 2002). Improvement of mass-rearing conditions has been suggested, especially of those environmental conditions that help to maintain male behavioral polymorphisms and sexual competitiveness (Ochieng-Odero 1994, Cayol 2000. Therefore, the development of methods to measure the impact of laboratory conditions on mass-reared insects becomes an important focus.…”

Comparison of Sexual Compatibility Between Laboratory and Wild Mexican Fruit Flies Under Laboratory and Field Conditions

The sexual compatibility between laboratory (LF) and wild (WF) strains of the Mexican fruit fly, Anastrepha ludens (Loew), was analyzed using analogous methodologies and experimental arenas under both laboratory and field conditions. Sexual compatibility was quantified with the following indices: the isolation index (ISI), male relative performance index (MRP), female relative performance index (FRPI), and the relative sterility index (RSI). ISI detected a certain level of incompatibility between strains under both laboratory and field conditions, because LF females tended to mate with LF males. LF mating performance was higher under laboratory than under field conditions. The relative performance indices for LF and the relative sterility index were higher in the laboratory than in the field. Differences between LF and WF in the times that males started calling and mating were observed in both environments. Importantly, WF males reduced their sexual activity under laboratory environments, whereas LF maintained similar activity levels in both conditions. The possible applications of the above-mentioned methods, not only to assess fly quality but also to determine the suitability of conditions in mass-rearing facilities, are discussed. Correlating laboratory quality to sexual behavior may contribute in the development of environmental parameters for mass-rearing facilities.

“…The effects of laboratory colonization on many aspects of insect behaviour are incremental, heterogeneous, and to a certain degree unpredictable, and many ideas have been developed as to how quality can be monitored in the laboratory and how Downloaded by [University of New England] at 22:53 18 May 2016 rearing systems can be adapted in an attempt to retain quality (Boller 1972;Chambers 1977;Huettel 1976;Ochieng-Odero 1994). Many quality parameters can be effectively monitored in the laboratory, for example, size, survival, etc., but the assessment of parameters related to behaviour would seem to be of little value when carried out under these conditions.…”
