“…The number of parasitized eggs is 34.7 and 40.4 for S. frugiperda and S. litura respectively. This is in line with the research of (Carneiro, Fernandes, Cruz, & Bueno, 2010) who tested the functional response of S. frugiperda with different exposure times that on the number of host eggs by 50 eggs, the number of parasitized eggs was 20-30 eggs. In general, T. remus has a type II functional response in which the more the number of hosts is given, the number of parasitized hosts is increasing.…”

INTRODUCTIONSpodoptera spp. (Lepidoptera: Noctuidae) are the common pest of Indonesia including Spodoptera litura and S. exigua (Kalshoven, 1981). Spodoptera litura is the most voracious among the genus of Spodopotera which is commonly found in leguminous plants (Tengkano & Suharsono, 2005) and S. exigua is commonly found in onion and other 170 plant species (Zhang, Huai, Helen, & Wang, 2011). In the meantime, Spodoptera frugiperda is a newly reported pest species of Indonesia in 2019.

“…The functional response of P. nigrispinus has been assessed in various cotton agroecosystems (Malaquias et al., ). Factors such as temperature (Malaquias et al., ), plant species (De Clercq et al., ), and plant physiology (Carneiro et al., ) influence the natural enemy's predation behavior. In addition, the developmental stages of both the predator (Hassanpour et al., ; Madadi et al., ) and the prey (Farhadi et al., ) are known to affect the attack efficiency of this biological control agent.…”

The functional response of a predator to the density of its prey is affected by several factors, including the prey's developmental stage. This study evaluated the functional response of Podisus nigrispinus (Dallas) (Hemiptera: Heteroptera: Pentatomidae) females to fourth instars and pupae of Alabama argillacea (H€ ubner) (Lepidoptera: Noctuidae), an important pest of cotton (Gossypium hirsutum L., Malvaceae) in Brazil. The prey were exposed to the predator for 12 and 24 h, and in densities of 1, 6, 12, 18, 24, and 30 items per predator female. The predation data were subjected to polynomial regression logistic analysis to determine the type of functional response. Holling and Rogers' equations were used to estimate parameters such as attack rate and handling time. Podisus nigrispinus females showed functional response types II and III by preying on larvae and pupae, respectively. The attack rate and handling time did not differ between the 12 and 24 h exposure times. Predation rate was higher at higher larval and pupal densities; predation was highest at a density of 30 prey items per female, and it was similar at 18 and 24 prey per predator. Understanding the interaction of predators and their food resources helps to optimize biological control strategies. It also helps the decisionmaking and the improvement of release techniques of P. nigrispinus in the field.

“…In the fourth type, the response curve is dome-shaped. Studies on the interaction of a natural enemy and its host, as the functional response, for instance, can be helpful in integrated pest management programs, once this helps determine the predation/parasitism dynamics of a natural enemy (Carneiro et al 2010). On the other hand, the success of the Integrated Pest Management (IPM) programs simultaneous use of biological control agents and chemical compounds are recommended (Hull and Beers 1985).…”

Abstract:Habrobracon hebetor Say is one of the most important natural enemies of the Helicoverpa armigera Hübner (Lep.: Noctuidae). In this study, the sublethal effects of LC 30 concentration of azadirachtin, cypermethrin, methoxyfenozide and pyridalil on the functional response of H. hebetor to different densities of 5th instars larvae of Ephestia kuehniella Zeller were evaluated. Young females were exposed to LC 30 of the insecticides for an appropriate time of exposure. Then, six randomly selected alive females were transferred individually to plastic Petri dishes (10 cm in diameter) and supplied with the following densities: 2, 4, 8, 16, 32 and 64 of 5th instars of E. kuehniella for 24 h. Eight replicates were considered for each insecticide treatment and the control. The results revealed a type II functional response in the control, and all of the insecticide treatments. This study showed that the control and the cypermethrin treatment had the shortest (0.4143 h) and longest (0.624 h) handling time, respectively. The highest (0.0035 per hour) and lowest (0.0029 per hour) attack rate was observed in pyridalil and cypermethrin treatments, respectively. Based on values of handling time, cypermethrin had the highest adverse effect on host-finding in H. hebetor.
