“…Therefore, these parameters should be obtained to enhance the information on a natural enemy's behavior and increase its efficacy (Fernandez-Arhex & Corley 2003), although functional response should not be taken into account alone to determine a potential species to be used in biological control programs (Lester & Harmsen 2002;Fernandez-Arhex & Corley 2003).…”

25, 50, 75, 100, 150, 200, 250 or 300 eggs of S. frugiperda for 24 h. Complete randomized design with ten replications was adopted. The parameters evaluated to construct the functional response curve were daily average parasitism, searching rate and oviposition time. It was observed that the higher the egg density, the higher the parasitism for 24-h and 48-h-old females although there was a tendency of parasitism stabilization at 150-egg density. The results showed a type II functional response curve for both 24-h and 48-h-old female.

“…These are characteristics of type II and type IV functional responses (van Alphen and Jervis 1996). A type IV response has never been observed in a parasitoid before (Fernandez-Arhex and Corley 2002), so it is more likely that M. plutellae has a type II response. Further experimentation (using higher host densities) could provide data to support or refute the inferences made in this paper about the functional response curves of D. insulare and M. plutellae.…”

“…It appears that D. insulare has a type I functional response curve: as the number of available hosts increased, D. insulare parasitized a larger number of hosts while maintaining a constant percentage parasitism. It is a somewhat unexpected result, as only one other parasitoid biological control agent (Eretmocerus eremicus (Hymenoptera: Aphelinidae)) is known to exhibit a type I functional response (Fernandez-Arhex and Corley 2002). It is important to note that the host densities tested in this experiment were relatively low compared to other experiments (Put nam 1968), and it is likely that the percentage parasitism by D. insulare would decrease when the number of available hosts reached a critical mass (as is evident with other type I functional response organisms) (van Alphen and Jervis 1996).…”

Parasitism levels by Diadegma insulare (Muesebeck) (Hymenoptera: Ichneumonidae) and Microplitis plutellae (Haliday) (Hymenoptera: Braconidae) at various densities of their host, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were assessed. Cages with densities of 10 hosts, 20 hosts, and 40 hosts were set up, with the cage volume (40 500 cm3) and number of wasps (2 females) remaining constant. The host populations were also exposed to the wasps for two different exposure times: 1 day and 3 days. The study showed that D. insulare was a better parasitoid overall, achieving a level of parasitism equal to or higher than M. plutellae at all densities. Microplitis plutellae performed best at a lower host density (76% ± 9% of 10 hosts vs. 43% ± 3% of 40 hosts). Diadegma insulare performed similarly at all densities tested (75% ± 5% of 10 hosts, 83% ± 4% of 20 hosts, and 79% ± 6% of 40 hosts). This suggests that D. insulare may be the better parasitoid overall and should be applied in severe, large-scale infestations, while M. plutellae may be better for small-scale infestations.

“…The maximum attack rates (T/Th) were 14.54, 24.74 and 20 Different letters in a row (A, B) indicate significant differences between different temperatures, P < 0.05. (Fernandez-Arhex & Corley, 2003). This may be due to the generally artificial experimental design in which parasitoids have a fixed time to search for hosts and there is a lack of any spatial complexity within patches (Fernandez-Arhex & Corley, 2003).…”

Abstract. Diaeretiella rapae MacIntosh (Hymenoptera: Aphidiidae) is one of the most common and successful parasitoids of the cabbage aphid. The functional response of D. rapae towards cabbage aphids was examined in laboratory studies at three constant temperatures, 17°C, 25°C and 30°C. D. rapae exhibited a type II functional response at all three temperatures. The search rates were uninfluenced by temperature whereas handling times differed significantly between 17°C and 25°C, and between 17°C and 30°C, but not between 25°C and 30°C. This study is a first-step in the evaluation of the effectiveness of D. rapae as a biocontrol agent of Brevicoryne brassicae at different temperatures.
