“…Thelytokous forms of Trichogramma may have great potential in this respect, as they offer several advantages. However, in the present study, the TdW + line showed reduced fitness and therefore may not be as good as the Td line when decision‐making only is considered. However, a single evaluation is insufficient to determine the potential of the TdW + line, especially as we also found positive effects of Wolbachia infection on the functional response of T .…”

“…In comparison with bisexual strains, some authors suggested that thelytokous Trichogramma may be better biological control agents because of these advantages: (1) a higher rate of population increase, as all wasps are female; (2) lower production costs because they do not ‘waste’ expensive hosts for the production of males during mass rearing; (3) easier population establishment because females do not need to mate to produce female offspring; (4) the ability to depress a host population to a lower level . However, whether a biological control agent is successful cannot be determined by consideration of the above factors alone, as Wolbachia are also able to affect other important biological control traits of a host in addition to reproduction phenotypes.…”

“…Besides, there were no significant differences in the developmental time at any stage, oviposition days, longevity, or fecundity between the thelytokous and arrhenotokous strains (Table 1). The fecundity of our arrhenotokous females was similar to that of arrhenotokous females (50.5 eggs/female) reported by Liu et al 33 Similar developmental time and longevity in other parasitoids with two reproductive modes have also been reported (e.g., pyralid moths parasitoid Venturia canescens 67,68 and lepidopterous cotton pest parasitoid Trichogramma pretiosum 69 ). In contrast, Ameri et al 23 found that the immature stage and longevity of arrhenotokous females were shorter than those of thelytokous females of the aphidiine parasitoid Lysiphlebus fabarum.…”

“…It was noteworthy that T. pretiosum is a thelytokous strain, which possibly led to the deviation in the consistency of biological parameters of three wasps. Previous studies have reported that the biological attributes of thelytokous and non‐thelytokous T. pretiosum were different, and the thelytokous strain had a higher fecundity and parasitism rate than non‐thelytokous strain (Prabhulinga et al, 2013; Prabhulinga et al, 2016). Besides, the developmental period was shorter in thelytokous form (Roopa et al, 2009).…”
