The relationship between the index of female's size, hind tibia length (HTL), and selected fitness parameters used in quality assessment of mass‐reared Trichogramma spp. (Hymenoptera, Trichogrammatidae) was investigated. The studied fitness parameters were: the number of mature eggs present in the ovaries of females 0–2 hours, as well as 1, 2 and 3 days old, lifetime fecundity, fecundity during a 24 h period, longevity in the presence and absence of the factitious host ( Ephestia kuehniella Zeller) and locomotor activity. The relationship between HTL and fitness parameters was analysed in 7 strains of Trichogramma spp. ( Trichogramma dendrolimi Matsumura, T. evanescens Westwood, T. maidis Pinturea et Voegelé and T. ostriniae Pang et Chen) using linear correlation. No significant relationship was found between HTL and egg complement, fecundity, longevity and locomotor activity. The results indicate that HTL used as an index of female's size is not suitable for quality assessment of Trichogramma reared on E. kuehnieIla.
