“…This type of response coincides with the results reported by Doker et al, (2016), Gotoh et al, (2004) and Song et al, (2016) (1985) and Xiao et al, (2013) mentioned that phytoseiid mites often prefer to feed on immature stages and eggs. On the other hand, Xiao and Fadamiro (2010), reported that N. californicus prefers nymphs over the eggs of P. citri; while Song et al, (2016) and Rezaie et al, (2017) expressed that N. californicus showed higher predation rate on T. urticae active stages than on the eggs.…”

Amblyseius orientalis (Ehara) (Acari: Phytoseiidae) is a native predatory mite species in China. It used to be considered as a specialist predator of spider mites. However, recent studies show it also preys on other small arthropod pests, such as Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). Experiments were conducted to investigate (1) prey preference of A. orientalis between Tetranychus cinnabarinus (Boisd.) (Acari: Tetranychidae) and B. tabaci, and (2) development, consumption and life table parameters of A. orientalis when reared on T. cinnabarinus, B. tabaci or a mix of both prey species. When preying on different stages of T. cinnabarinus, A. orientalis preferred protonymphs, whereas when preying on different stages of B. tabaci, A. orientalis preferred eggs. When these two most preferred stages were provided together (T. cinnabarinus protonymphs and B. tabaci eggs), A. orientalis randomly selected its prey. Amblyseius orientalis was able to complete its life cycle on B. tabaci eggs, T. cinnabarinus protonymphs, or a mix of both prey. However, its developmental duration was 53.9% and 30.0% longer when reared on B. tabaci eggs than on T. cinnabarinus and a mix of both prey, respectively. In addition, it produced only a few eggs and its intrinsic rate of increase was negative when reared on B. tabaci eggs, which indicates that B. tabaci is not sufficient to maintain A. orientalis population. The intrinsic rates of increase were 0.16 and 0.23 when A. orientalis was fed on the prey mix and T. cinnabarinus, respectively. These results suggest that although B. tabaci is a poor food resource for A. orientalis in comparison to T. cinnabarinus, A. orientalis is able to sustain its population on a mix of both prey. This predatory mite may thus be a potential biological control agent of B. tabaci when this pest co-occurs with the alternative minor pest T. cinnabarinus.

“…Interestingly, this exponential response curve has also been found on many other insects and arthropods species (Murdoch 1969;Xiao et al 2013;Zuharah & Lester 2011). According to some literatures, predators that displayed the Type II functional response are generally known as successful biological control agents (Reis et al 2003;Timms et al 2008;Xiao & Fadamiro 2010).…”

The rice green leafhopper Nephotettix virescens Distant (Hemiptera: Cicadellidae), zigzag leafhopper Recilia dorsalis Motschulsky (Hemiptera: Cicadellidae), and brown planthopper Nilaparvata lugens Stål (Hemiptera: Delphacidae) are the most economically important insect pests infesting rice crop. Paederus fuscipes Curtis has been reported as the natural predator for these rice pest species in Southeast Asia. Under laboratory conditions, we evaluated the prey preference of this generalist predator when it encountered the three main agricultural pests of rice plant. P. fuscipes typically displayed a Type II functional response for all prey species. However, at high prey densities they consumed predominantly R. dorsalis with highest attack rate on dead R. dorsalis prey. Conversely, significantly highest time was needed to handle live R. dorsalis. When various density of preys was tested simultaneously, the predator showed greater preferences towards R. dorsalis and Ni. lugens. We observed the behavioral response of P. fuscipes predator on its prey items. Highest number of searching and capturing attempt was most frequently displayed on live Ni. lugens prey species. Whereas, P. fuscipes spent more feeding time in consuming dead prey compared to the alive ones. Overall, P. fuscipes showed successful control of small and soft body crop pests at low prey density.
