“…Although reviews indicate that the type II functional response is more frequently recorded for parasitoids and type III is not prevalent in parasitic insects, the form of the functional response on its own does not determine the success or failure of parasitoids in biological control (Fernandez-Arhex & Corely, 2003). Other factors like numerical response, intrinsic growth rates, host patchiness, and competition (Pervez, 2005), as well as abiotic and biotic environmental factors such as habitat heterogeneity (Lipcius & Hines, 1986), temperature (Mahdian et al, 2006;Jalali et al, 2010), host plant (Salehi et al, 2016) and light (Koshi & Johnson, 2002) also affect the effi cacy of natural enemies in pest management.…”

“…Attack rate and handling time are parameters that also help determine the magnitude of functional responses (Omkar 2005). The handling time is an important and reliable indicator of the amount of prey consumed and the predator efficiency as it determines the cumulative time spent on capturing, killing, and digesting the prey (Veeravel & Baskaran 1997).…”

The tomato/potato psyllid (TPP), Bactericera cockerelli, is a serious pest of some agricultural and ornamental plants, especially of the Solanaceae family. It has been an invasive species in New Zealand since 2006, heavily impacting the potato and tomato industry. The functional and numerical responses of the phytoseiid predators Amblydromalus limonicus and Neoseiulus cucumeris were examined by offering a range of prey densities (two, four, eight, 12, 16, 20, 24 and 28 TPP eggs or 1 st instar nymphs) and compared on a capsicum leaf disc under 25 ± 1ºC, 85% ± 5% RH and a 14:10 h light: dark (L:D) photoperiod. Both species displayed a type 2 functional response when fed on eggs or 1 st instar nymphs of TPP, indicating an increase in the number of prey killed with an increase in prey population density. The results were analysed by using a logistic regression and Holling disc equation. A. limonicus had a higher attack rate for both eggs (0.05 ± 0.01) and 1 st instar nymphs (0.06 ± 0.01) than N. cucumeris, which had an attack rate of (0.03 ± 0.01) for eggs and (0.02 ± 0.01) for 1 st instar nymphs of TPP. N. cucumeris had a longer handling time for both eggs (3.68 ± 0.67 hrs) and 1 st instar nymphs (2.50 ± 0.79 hrs) compared with A. limonicus, with a handling time of (1.74 ± 0.23 hrs) for eggs and (1.15 ± 0.15 hrs) for 1 st instar nymphs. A. limonicus consistently produced significantly more eggs than N. cucumeris across all densities when fed on either eggs or 1 st instar nymphs of TPP. However, the results showed the lack of numerical response of both predator species to prey density. The stronger functional response of A. limonicus to TPP eggs and 1 st instar nymphs indicates that this species can potentially be a more effective biocontrol agent of TPP than N. cucumeris.

“…More detailed studies considering different preys, precise statistical analyses and the effect in the different larval instars are required to know the specific details of the functional response of predatory syrphid larvae. The functional response of most polyphagous predators is one of the key aspects to consider their use as BCAs (Murdoch and Oaten, 1975), but field-based studies are always needed to confirm experimental results under controlled conditions (Pervez and Omkar, 2005;Montoya-Alvarez et al, 2010).…”

The average recorded duration of A. exotica development was 2.0, 7.4 and 5.7 days for eggs, larvae and pupae respectively, and 15.04 days from egg to adult emergence. The adult longevity was not significantly sex dependent, but imagoes lived longer than in previous studies. The offspring sex ratio was favorable to males. The mortality and survival rate were recorded on a daily basis for all immature stages and adults. The age specific survival rate was determined and the highest mortality occurred in eggs followed by mortality in 1st and 2nd instar larva.Moreover, in the present study different levels of aphid densities 10, 30, 40, 50, 60, 70, 80 and 100 were used to calculate the functional response. Based on logistic regression analyses the three instar larvae and the whole larval stage (first to third instar) exhibited a type II functional response. Handling time was shortest for the third larval instar followed by second and first instars. Potential use of A. exotica in augmentative biological control is discussed.
