“…Lanzoni et al (2004) report an intrinsic rate of increase of 0.114 day -1 for H. variegata, which is higher than that of Harmonia axyridis (Pallas) and Adalia bipunctata (L.) fed on Myzus persicae (Sulzer). Farhadi et al (2011) report an r m value of 0.203 ± 0.005 day -1 for H. variegata fed bean aphids, Aphis fabae Scopoli, which is similar to the value recorded in this study for H. variegata fed on RWA reared on the susceptible cultivar of wheat. In addition, parameters other than R 0 have similar values.…”

“…The predation rates of some other natural enemies have been studied using agestage two sex consumption rate MSChart software (Bailey, Chang, Lai, & Hsu, 2010;Chi & Yang, 2003;Farhadi et al, 2011;Yu et al, 2005). Chi and Yang (2003) noted that the net predation rate for P. japonica (Coleoptera: Coccinellidae) fed on M. persicae was 1199.5 ± 212.3 aphids.…”

“…Yu, Chi, and Chen (2005) applied the same method to study the predation rate of Lemnia biplagiata Schwartz (Coleoptera: Coccinellidae) feeding on Aphis gossypii. Farhadi, Allahyari, and Chi (2011) also studied the predation rate of Hippodamia variegata Goeze (Coleoptera: Coccinellidae) feeding on Aphis fabae. All these studies show the advantage of using an age-stage, two-sex life table.…”

Predation rate and numerical response are basic to any investigation of predatorprey relationships and key components in the selection of predators for biological control. The density-dependent predation rate and numerical response of Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae) to varying densities (5, 10, 20, 40, 60 and 80) of third-instar Aphis craccivora (Koch) (Hemiptera: Aphididae), were studied in laboratory conditions [23±1°C, 70 ± 5% relative humidity (RH), and a photoperiod of 16:8 h L:D. Predation rate data were analysed using the age-stage, two-sex consumption rate software. Net consumption rate (C 0 ) increased by increasing prey density. The lowest and highest net consumption rates were 20.75 and 190.8 prey nymphs at densities of 5 and 80 A. craccivora. The transformation rate from prey population to predator offspring (Q p ) increased by increasing prey density. The reproductive numerical response, in terms of eggs laid, increased curvilinearly with increasing prey density. Females laid 121.375 ± 4.301 eggs when exposed to the highest prey density (80) and 52.5 ± 1.544 eggs at lowest prey density (5). It can be concluded that different densities of A. craccivora influenced the reproductive performance of A. aphidimyza in terms of predation rate and numerical response.

“…Because they ignore the effects of male predators in biological control studies and male consumers in agricultural studies, female age-4 specific life tables are incapable of accurately describing predator-prey relationships or growth in two-sex and stage-structured populations. Using the age-stage, two-sex life table 6,7 has solved these problems and is now often used in ecological studies 8,9,10,11,12 .…”

“…However, because the predation ability generally varies with age and stage 8,9,10,11 , the finite predation rate is a better indicator of predation potential than the finite rate. If ψ < 1, then ω < λ.…”

To better understand the effect of individual- and group-rearing conditions on predator performance, we studied the life table and predation rate of the predatory mite, Phytoseiulus persimilis Athias-Henriot, after the mites had been individually- or group-reared on two-spotted spider mites, Tetranychus urticae, eggs at 25±1°C, 65±5% RH and a photoperiod of 16: 8 (L:D) h. The net reproductive rate (R0), intrinsic rate of increase (r), net predation rate (C0), finite predation rate (ω) in the individually-reared predators were 40.61 offspring, 0.2594 d-1, 437.3 T. urticae eggs, and 4.8668 preys/d, respectively. Similar values were obtained when the predators were reared in groups (R0 = 43.10 offspring, r = 0.2837 d-1, C0 = 420.9 T. urticae eggs, and ω = 5.9054 preys/d). Mean adult longevities were 28.42 and 25.29 d for group-reared male and female predators, respectively; these values were significantly shorter than those of individual-reared mites (49.87 d for male and 36 d for female). Our results showed that P. persimilis mites could be group-reared in biological control programs without negative effect on their growth and predation potential.
