“…Most of the studies revealed that host age is an important factor that is considered by the parasitoids (Jowyk & Smilowitz 1978;Vinson & Iwantsch 1980) because the parasitoids must be provided with a suitable environment (the hosts and their feeding habitat) for their offspring (Qiu et al 2013;Chu et al 2014). Unlike gregarious koinobiont parasitoids, which prefer later instars in order to produce more offspring (Elzinga et al 2003), solitary parasitoids choose slowly-growing larvae as their hosts (Mironidis & Savopoulou-Soultani 2009;van Nouhuys et al 2012) and they regulate and adjust host development rate in favor of their own development (Khafagi & Hegazi 2004).…”

“…The intrinsic rate of increase can be also used to determine the finite rate of increase (λ), which depicts the number of times the population increases per unit time in a generation. Population growth parameters such as intrinsic rate of increase, net reproductive rate, and finite rate of increase are influenced by nature and quality of the host (Qiu et al 2013).…”

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most destructive pests of tomato, has recently invaded India. Before recommending any bio-control agent for its control, it is important to study the demographic parameters of the bio-agent on the pest. The present study evaluates the demographic parameters of indigenous trichogrammatids namely Trichogramma achaeae Nagaraja and Nagarkatti, T. pretiosum Riley, T. chilonis (Ishii), and T. pieridis Nagaraja and Prashanth against this pest, aiming to select the most effective egg parasitoid species. Significant differences were observed among the demographic parameters of different Trichogramma spp. Parasitization potential of a thelytokous strain of T. pretiosum was the highest, followed by T. achaeae, T. chilonis, and T. pieridis. Population growth parameters net reproductive rate, intrinsic rate of natural increase, finite rate of increase, and weekly multiplication rate were highest, and generation time and doubling period were shortest for T. pretiosum, followed by T. achaeae, T. chilonis, and T. pieridis. The study concluded that T. pretiosum could be considered a potential candidate for biological control of T. absoluta; however, field evaluation is required before final recommendation.

“…Our results support previous observations reporting a higher suitability of two and three-day-old M. vitrata caterpillar to Apanteles taragamae (Viereck) (Hymenoptera: Braconidae) 24 . In the same vein, the second instar of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) was identified as the most suitable host stage for Microplitis similis (Lyle) (Hymenoptera: Braconidae), based on the high values of r and Ro 29 . It was shown that parasitizing early host stages can reduce the development time in koinobionts parasitoids 16 ; however, adult fitness of the offspring may be affected, in terms of short life expectancy, small size eggs, and reduced oviposition period 30 .…”

Therophilus javanus (Bhat & Gupta) is an exotic larval endoparasitoid newly imported from Asia into Africa as a classical biological control agent against the pod borer Maruca vitrata (Fabricius). The parasitoid preference for the five larval instars of M. vitrata and their influence on progeny sex ratio were assessed together with the impact of larval host age at the time of oviposition on development time, mother longevity and offspring production. In a choice situation, female parasitoids preferred to oviposit in the first three larval instars. The development of immature stages of the parasitoid was observed inside three-day-old hosts, whereby the first two larval instars of T. javanus completed their development as endoparasites and the third larval instar as ectoparasite. The development time was faster when first larval instars (two- and three-day-old) of the host caterpillars were parasitized compared to second larval instar (four-day-old). The highest proportion of daughters (0.51) was observed when females were provided with four-day-old hosts. The lowest intrinsic rate of increase (r) (0.21 ± 0.01), the lowest rate of increase (λ) (1.23 ± 0.01), and the lowest net reproductive rate (Ro) (35.93 ± 6.51) were recorded on four-day-old hosts. These results are discussed in the light of optimizing mass rearing and release strategies.
