Observations on the post-emergence and mating behaviours of adults of the Mediterranean flour moth, Anagasta kuehniella (Zeller) and investigation on some of their reproductive properties

Observations on the post-emergence and mating behaviours of adults of the Mediterranean flour moth revealed that the adults could not fly 15-20 min. after their wings expansion. Despite of non-feeding normally, adults fed from sucrose solution. Females were polygamous and mated 3 times. Sexual dimorphism is obvious in adults, so that, males have a smaller body and their abdomens seem elongated and rectangonal, while, females have a bigger body and before the end of oviposition period, their abdomens seem fusiform and swollen. Results of present study indicated that adding bran to the rate of 25% could increase femalesʹ fertility and also could affect some of desired aspects of mass rearing, positively. Malesʹ longevity lasted more than that of females. Females oviposited up to 12 days, but laid most of their eggs (95%) during the first 5 days. By considering this and also mean of femalesʹ longevity (about 7 days), it is recommended that collecting eggs could be continue up to 5 days. There were high and positive con-elation coefficients between weight of female 5th instar larvae, pupae and adults, and length of femalesʹ hind tibia with number of eggs were laid by females.
